WEBVTT 00:01.450 --> 00:06.080 Prof: You remember, when I was talking about 00:06.078 --> 00:12.018 Europe, we discussed the fact that during marriage Europeans 00:12.024 --> 00:15.464 just had babies, in a sense willy-nilly, 00:15.458 --> 00:19.338 but we also said it was nowhere near the maximum that humans are 00:19.344 --> 00:22.204 capable of, but we thought it was sort of 00:22.199 --> 00:24.829 cultural constraints, late marriage, 00:24.826 --> 00:26.466 and stuff like that. 00:26.470 --> 00:30.550 Now we come to China in which the birth rate within marriage 00:30.547 --> 00:34.207 was quite a bit lower and I introduced the question of 00:34.210 --> 00:37.940 whether this was voluntary in the sense of individually 00:37.943 --> 00:40.393 decided, an individual decides what they 00:40.389 --> 00:43.609 want and acts on it, or was this low birth rate due 00:43.606 --> 00:48.036 to cultural constraints in a crowded household with maybe the 00:48.040 --> 00:50.700 grandmother sleeping beneath you. 00:50.700 --> 00:53.470 There's no opportunity, if the cultural rules say you 00:53.467 --> 00:56.537 can't be friends with your wife, there may be a reduction in 00:56.541 --> 00:59.031 passion, and the conclusion that I gave 00:59.031 --> 01:03.251 you was that this didn't seem to be an individual decision kind 01:03.250 --> 01:06.040 of thing but a cultural kind of thing. 01:06.040 --> 01:09.760 It's a little bit out of place but I just can't-- 01:09.760 --> 01:13.080 I love this data so much, it's so very striking as an 01:13.082 --> 01:16.532 example of people that are not individually voluntarily 01:16.534 --> 01:18.584 controlling their fertility. 01:18.580 --> 01:21.160 How would you tell if someone is? 01:21.159 --> 01:25.029 --You have a big huge population, you can't interview 01:25.025 --> 01:28.345 all of them, maybe it's a dead population, 01:28.352 --> 01:32.402 old, how do you tell whether they're making individual 01:32.397 --> 01:33.387 decisions? 01:33.390 --> 01:37.120 Well you have--one of the ways of doing it is to consider 01:37.120 --> 01:40.520 individual events in their lives that you think, 01:40.519 --> 01:43.579 under any reasonable idea of what it is to be a human, 01:43.580 --> 01:45.700 would affect their fertility. 01:45.700 --> 01:50.260 One of those events is the death of a child. 01:50.260 --> 01:53.510 There's many--I mean I think you all would naturally say, 01:53.510 --> 01:56.080 if you want a certain number of children you're going to control 01:56.078 --> 01:57.828 consciously-- if your children die, 01:57.830 --> 02:00.110 you're going to try harder to have more, 02:00.109 --> 02:01.699 you're going to try longer. 02:01.700 --> 02:06.040 Here is a Chinese population from 1982, so we're talking 02:06.039 --> 02:11.009 about just at the time when the one child policy is starting. 02:11.008 --> 02:15.078 These are women who have finished their childbearing by 02:15.084 --> 02:19.464 1982, so it's the generation exactly prior to the one-child 02:19.460 --> 02:20.290 policy. 02:20.288 --> 02:23.898 It gives you a lot of data but look over here, 02:23.900 --> 02:26.600 it says what happened to the first four children, 02:26.598 --> 02:30.428 and it gives you two cases: all the children died or all 02:30.432 --> 02:31.202 survived. 02:31.199 --> 02:34.479 There's a lot of intermediate cases which are not shown in 02:34.484 --> 02:37.944 this particular graph and it's spread out by age to seeing if 02:37.941 --> 02:39.901 there some sort of age effect. 02:39.900 --> 02:44.140 Here is the mother's age at last birth, so if all of them 02:44.138 --> 02:48.748 survived--if all of them died you would think the mother would 02:48.754 --> 02:50.954 really want to have more. 02:50.949 --> 02:54.959 She stops giving birth at age 38.7. 02:54.960 --> 02:58.380 If they all survived, 1/10th of a year, 02:58.378 --> 03:02.608 she stops giving birth 1/10th of a year earlier, 03:02.610 --> 03:04.590 one month earlier. 03:04.590 --> 03:09.500 Same, a little bit older group you have 0.4 year, 03:09.495 --> 03:15.115 maybe four months later, and here's 0.1 months again for 03:15.116 --> 03:19.916 women who are 20--their age at first birth. 03:19.919 --> 03:23.689 I'm sorry; the age at which they stop depends on the age at 03:23.686 --> 03:26.086 which they start to a large degree. 03:26.090 --> 03:29.290 The numbers of this way are different because they started 03:29.289 --> 03:32.029 at different ages, but there's no difference 03:32.026 --> 03:35.876 within an age group depending on whether all four children died 03:35.884 --> 03:37.944 or all four children survived. 03:37.940 --> 03:43.390 That's just--to me that's an amazing set of statistics that 03:43.394 --> 03:47.944 apparently the continuation, the attempt to have as many 03:47.942 --> 03:51.392 children as possible just does not depend on that event. 03:51.389 --> 03:55.539 Here's another example of this, this is-- 03:55.538 --> 03:58.608 as was discussed in most of Asia, a lot of the world, 03:58.610 --> 04:01.170 and especially China, they need males, 04:01.169 --> 04:04.109 sons are much preferred over daughters. 04:04.110 --> 04:10.140 Here's a very nicely displayed set of data saying how many sons 04:10.137 --> 04:13.537 have you had, how many daughters? 04:13.538 --> 04:18.328 Here's--that have had no son or no daughter, and the question is 04:18.334 --> 04:20.394 how many of them proceed? 04:20.389 --> 04:24.259 These numbers show the fraction that proceeds to have the first 04:24.259 --> 04:24.759 birth. 04:24.759 --> 04:29.589 When they get married and they have no children, 04:29.591 --> 04:35.761 neither a son nor a daughter 0.958--I'm sorry they have a son 04:35.761 --> 04:38.481 first; they have one son or one 04:38.483 --> 04:39.193 daughter. 04:39.190 --> 04:44.130 Those that have a son 95.8% of them proceed to have a second 04:44.132 --> 04:48.072 child and that can be either a boy or a girl. 04:48.069 --> 04:53.519 If their first child is a daughter 96.8% proceed, 04:53.519 --> 04:55.739 so you don't have to look up here and the details aren't 04:55.735 --> 04:58.805 important, but look at for instance those 04:58.810 --> 05:05.710 that have seven sons in a row, and 72%, 72.5% of them proceed 05:05.706 --> 05:08.906 to get pregnant again. 05:08.910 --> 05:12.810 Here's seven daughters in a row, they want the sons, 05:12.810 --> 05:15.560 and they may not want daughters, 76%, 05:15.564 --> 05:19.164 a 3.5% difference, almost no difference in their 05:19.158 --> 05:19.998 life. 05:20.000 --> 05:23.320 Again, how many of them, after having seven sons, 05:23.319 --> 05:27.019 you presume that's enough sons, whereas seven daughters they 05:27.017 --> 05:30.777 would be desperate to have more but there's a very small-- 05:30.778 --> 05:35.798 a 3% difference between the fraction of them that proceed. 05:35.800 --> 05:37.720 You can also see the numbers are very high; 05:37.720 --> 05:41.280 those that have had seven children already, 05:41.279 --> 05:44.329 76% proceed to have another birth. 05:44.329 --> 05:47.309 They just keep going, and whether they have all 05:47.314 --> 05:49.914 daughters in a row, or all sons in a row, 05:49.908 --> 05:52.048 makes very little difference. 05:52.050 --> 05:56.200 Finally at eight there is--it is a 10%-- 05:56.199 --> 05:58.579 less than, yes, a 10% difference, 05:58.576 --> 06:01.406 but whether that's-- that doesn't fit with the rest 06:01.406 --> 06:03.436 of the graph but it's still very small difference. 06:03.439 --> 06:08.259 Here's the last graph of this nature. 06:08.259 --> 06:11.449 This is again the age at the mother's last birth, 06:11.447 --> 06:14.167 and again, it's the same kind of graph. 06:14.170 --> 06:17.630 Those that have had eight daughters in a row versus those 06:17.629 --> 06:20.459 that have eight sons in a row, and you think, 06:20.459 --> 06:23.579 in a son desiring culture, if they were controlling their 06:23.583 --> 06:25.593 fertility in any individualistic way, 06:25.589 --> 06:28.599 that the ones with a lot of sons would say, 06:28.600 --> 06:31.490 okay enough and the ones with a lot of daughters would be 06:31.487 --> 06:33.237 desperate to finally have a son. 06:33.240 --> 06:36.480 Look at the difference, the age of 41.4, 06:36.476 --> 06:40.546 if they have eight sons in a row and the age 41.7, 06:40.545 --> 06:42.865 again 3/10ths of a year. 06:42.870 --> 06:49.040 They try just a little bit longer, three months longer. 06:49.040 --> 06:53.510 Basically I think what this data is telling you is that 06:53.509 --> 06:56.149 people are, for sure, not responding to the 06:56.149 --> 06:58.439 most important fertility events in their life, 06:58.440 --> 07:01.250 either the sex composition of their children or the death of 07:01.245 --> 07:04.735 the children; they're just having children. 07:04.740 --> 07:10.790 Not at an enormous rate because of the cultural things that 07:10.786 --> 07:16.306 everybody is behaving under, not with respect to their 07:16.312 --> 07:20.382 individual experiences and desires. 07:20.379 --> 07:24.369 This is the context into which the one-child-- 07:24.370 --> 07:26.120 first the Wan, Xi, Shao, the later, 07:26.120 --> 07:30.800 longer, fewer policy drops in and then ten years later the 07:30.798 --> 07:33.588 one-child policy, so it gives you an 07:33.593 --> 07:36.673 amazing--here's a population that's just finished 07:36.673 --> 07:40.523 childbearing when the policy starts and there's apparently no 07:40.521 --> 07:43.411 thought whatsoever of individually controlling 07:43.408 --> 07:44.498 fertility. 07:44.500 --> 07:46.890 All of a sudden the government tells you, 07:46.889 --> 07:50.879 hey you got to have fewer children, 07:50.879 --> 07:55.079 and I showed you the rate of fall, the rate of fall during 07:55.077 --> 07:57.357 the 1970s was just fantastic. 07:57.360 --> 08:01.240 Then after that fall, again as I told you last time, 08:01.235 --> 08:04.955 to control momentum, they instituted the one-child 08:04.958 --> 08:08.528 policy and the number of births levels off. 08:08.528 --> 08:11.608 Why does the number of births level off? 08:11.610 --> 08:16.170 This is again the fertility drop, this is the longer, 08:16.165 --> 08:21.065 later, fewer policy in the 1970s and that's where you get 08:21.069 --> 08:24.239 the big drop; 1980 the one-child policy, 08:24.242 --> 08:26.382 you don't get any further drops. 08:26.379 --> 08:32.759 That was a sign of--well, an incompetent government, 08:32.761 --> 08:38.771 an incompetently carried out fertility policy. 08:38.769 --> 08:41.909 It turns out that one arm of the government was doing 08:41.907 --> 08:45.107 something to the opposite effect of another arm of the 08:45.105 --> 08:46.005 government. 08:46.009 --> 08:52.929 Here the Chinese were--for women's rights issues and to 08:52.929 --> 08:55.079 control-- somewhat control the 08:55.082 --> 08:56.982 population--they were encouraging later marriage, 08:56.980 --> 08:59.210 they didn't want girls married at 13, 08:59.210 --> 09:00.800 14,15 and so forth. 09:00.798 --> 09:03.638 It had been very successful, the revolution is out here, 09:03.639 --> 09:08.259 and the age of marriage is already up to 19.5 or so by 1965 09:08.255 --> 09:11.995 and they're being very successful and the age of 09:11.996 --> 09:17.486 marriage keeps going up until it reaches a quite respectable 23, 09:17.490 --> 09:19.260 that's older than basically all of you are-- 09:19.259 --> 09:21.529 most of you, not all of you. 09:21.529 --> 09:24.169 It reaches a peak there. 09:24.168 --> 09:25.288 Then what does the government do? 09:25.288 --> 09:29.328 It says well we're doing great, we're now very worried, 09:29.325 --> 09:33.725 this is the year where they introduced the one-child policy, 09:33.734 --> 09:36.354 we want this to continue on up. 09:36.350 --> 09:39.250 They don't have good demographic statistics and they 09:39.245 --> 09:42.055 don't know this data, they don't actually know what 09:42.063 --> 09:43.973 age people are actually marrying at, 09:43.970 --> 09:49.880 so they have an official age which was actually above this 09:49.875 --> 09:54.095 and they-- I'm sorry, they raised that age 09:54.104 --> 09:59.594 to prevent more marriages but since people were below that 09:59.591 --> 10:02.551 what happened was-- let's see I'm getting this 10:02.552 --> 10:02.912 backwards. 10:02.908 --> 10:06.348 They--anyway the result of a policy they had an opposite 10:06.352 --> 10:08.822 result, that the result of instituting 10:08.817 --> 10:12.487 a new policy intending to raise marriage age reduced marriage 10:12.490 --> 10:13.410 age instead. 10:13.408 --> 10:16.568 Then you see when they introduce the one-child policy 10:16.567 --> 10:19.967 the mean age of marriage goes down and it goes down quite 10:19.966 --> 10:21.056 significantly. 10:21.058 --> 10:25.588 The one-child policy saying you should have fewer children is 10:25.594 --> 10:30.054 working oppositely to a new policy that actually reduces the 10:30.052 --> 10:33.002 age at marriage and increases the . 10:33.000 --> 10:35.990 The result is, this is the number of new 10:35.991 --> 10:38.591 marriages, first marriages, 10:38.586 --> 10:42.876 and there's a rise here, then there's kind of dipsy 10:42.884 --> 10:45.184 doodles, and then, just at the time of 10:45.184 --> 10:48.174 the one-child policy, the number of new marriages 10:48.172 --> 10:48.922 goes crazy. 10:48.918 --> 10:52.988 This big rise in the number of marriages, 10:52.990 --> 10:55.800 and remember 98% of Chinese women, when the get married, 10:55.798 --> 10:57.848 get pregnant right away, so the next year they had 10:57.851 --> 11:00.881 babies, this counteracts basically all 11:00.878 --> 11:04.268 of the effect of the one-child policy. 11:04.269 --> 11:07.989 That's one branch of government making one set of laws, 11:07.994 --> 11:11.584 not having the data and not being in accord with what 11:11.580 --> 11:14.270 another set of government is doing. 11:14.269 --> 11:17.979 In fact the one-child policy--I don't want to leave you with 11:17.976 --> 11:21.556 impression that the one-child policy had no effect but you 11:21.557 --> 11:23.817 have to do different statistics. 11:23.820 --> 11:28.510 Remember the total fertility rate takes all the women that 11:28.508 --> 11:31.638 are in an age group, whether they're married or not, 11:31.639 --> 11:33.319 and ask how many children they're having. 11:33.320 --> 11:37.560 Well when you have a big change in the fraction of women married 11:37.559 --> 11:40.589 then you have to use a different statistic. 11:40.590 --> 11:43.800 When the age of marriage changes, as it did in China at 11:43.804 --> 11:46.234 that time, you have to now look at a new 11:46.230 --> 11:49.530 statistic called the parity progression ratio which is very 11:49.532 --> 11:52.552 much like those triangle graphs that I showed you. 11:52.548 --> 11:59.468 This says--this black line is how many proceed from having no 11:59.469 --> 12:05.349 children to having one child, so the fraction of women--and 12:05.346 --> 12:08.286 this is in the 95% range or something. 12:08.288 --> 12:11.328 Basically all the Chinese women, at this time when they 12:11.331 --> 12:13.981 get married, give birth to their first child. 12:13.980 --> 12:17.570 Now the next number is those that already have one child, 12:17.571 --> 12:20.971 what fraction of them proceed to have two children? 12:20.970 --> 12:24.820 The answer is, before this policy, 12:24.817 --> 12:30.377 even more than the one, 98% of women that already have 12:30.380 --> 12:35.020 one child proceed to have a second child and that may be 12:35.020 --> 12:39.290 that in this group are fairly-- are sterile women or sterile 12:39.293 --> 12:41.953 men and so that may be the difference between here, 12:41.950 --> 12:43.390 but we don't have that data. 12:43.389 --> 12:46.169 Again, this is very, very high and then the other 12:46.173 --> 12:49.713 numbers, those that have two children how many go to three? 12:49.710 --> 12:53.220 Those that have three children how many go to four or more and 12:53.221 --> 12:55.871 so forth and we don't have data before this. 12:55.870 --> 12:59.910 You can see that the first child is uninterrupted; 12:59.908 --> 13:01.948 the Wan, Xi, Shao, the later, 13:01.952 --> 13:05.822 longer, fewer policy and the one-child policy does not 13:05.820 --> 13:08.010 interrupt the first birth. 13:08.009 --> 13:11.149 That goes on as normal which is what is expected, 13:11.149 --> 13:14.569 but going to a second child now at the time of the introduction 13:14.570 --> 13:20.780 of the one-child policy, this crashes as does later 13:20.784 --> 13:22.244 births. 13:22.240 --> 13:28.250 The one-child policy did have an effect if you look at those 13:28.245 --> 13:32.065 already married, but the two different policies, 13:32.068 --> 13:35.358 one lowering the age of marriage counteracts the effect 13:35.360 --> 13:39.200 and for a number of years the fertility rate stays constant. 13:39.200 --> 13:42.070 We've just had some visitors, let me show what I was talking 13:42.070 --> 13:42.460 about. 13:42.460 --> 13:45.640 This is the birthrate in China, what's called the total 13:45.639 --> 13:48.739 fertility rate, and here is 1970 when the 13:48.741 --> 13:52.341 later, longer, fewer policy was introduced and 13:52.337 --> 13:56.547 it was the decade of the 1970s where the fertility rate in 13:56.546 --> 13:57.576 China fell. 13:57.580 --> 14:01.970 In 1979/1980 the one-child policy is introduced and for 14:01.966 --> 14:06.106 about a decade or so the birthrate does not decrease 14:06.110 --> 14:07.330 under that. 14:07.330 --> 14:14.530 We have some guests apparently. 14:14.528 --> 14:18.148 What was happening was that in the cities, 14:18.149 --> 14:20.929 as I mentioned, there was a very significant 14:20.932 --> 14:24.272 birth drop in the 1960s, even before the government 14:24.274 --> 14:26.644 was--then in the 1970s, during Wan, Xi, 14:26.638 --> 14:30.118 Shao, the city populations went down to below fertility level. 14:30.120 --> 14:34.100 In the countryside's, even though there was a big 14:34.097 --> 14:38.077 drop in the 1970s, it wasn't anything like it was 14:38.077 --> 14:39.567 in the cities. 14:39.570 --> 14:44.180 As you heard from Qing who talked about her family's 14:44.182 --> 14:46.792 experience, in the cities there were many 14:46.785 --> 14:48.625 people that worked for the government, 14:48.629 --> 14:50.479 and so were under tight government control. 14:50.480 --> 14:52.790 Many of them worked in government owned factories so 14:52.785 --> 14:54.545 were under tight government control, 14:54.548 --> 14:58.318 and in general, in cities there is much more 14:58.316 --> 15:01.116 ability to control the people. 15:01.120 --> 15:04.900 However, at that time, 80% of Chinese people lived in 15:04.899 --> 15:05.699 villages. 15:05.700 --> 15:10.000 It was still a very rural country and there the story is 15:10.000 --> 15:10.940 different. 15:10.940 --> 15:12.900 Among other things, in many villages, 15:12.899 --> 15:15.729 all the people are related, they're all relatives. 15:15.730 --> 15:19.300 So, the professor who's got the next lab to mine is named Zhong 15:19.304 --> 15:22.484 and in his village everybody is a Zhong, and they're all 15:22.476 --> 15:23.166 related. 15:23.168 --> 15:27.798 If people don't believe in a policy, 15:27.798 --> 15:30.088 they don't want to obey the government and everybody is 15:30.091 --> 15:33.031 related, your uncle second removed can't 15:33.029 --> 15:37.329 really enforce a policy on you if you're a relative, 15:37.330 --> 15:41.390 especially in a culture where kinship means so much and the 15:41.394 --> 15:44.694 relationship between relatives means so much. 15:44.690 --> 15:52.660 The one-child policy was much, much less successful in the 15:52.660 --> 15:54.620 countryside. 15:54.620 --> 15:58.020 Similarly, the cities were beginning to have excess jobs 15:58.022 --> 16:01.242 and people were streaming out of the countryside, 16:01.240 --> 16:03.870 also because of the population growth there was no land left, 16:03.870 --> 16:06.020 so they were streaming out of the countryside going into the 16:06.024 --> 16:09.344 cities, they didn't have legal living 16:09.335 --> 16:10.245 permits. 16:10.250 --> 16:12.800 They have a system where you document where you live and you 16:12.796 --> 16:15.466 have to stay there and they were not allowed officially to come 16:15.472 --> 16:17.832 into the cities, but of course they did, 16:17.830 --> 16:21.110 and so the government didn't know where they were and 16:21.107 --> 16:24.887 basically had no control over them and so they were very hard 16:24.890 --> 16:25.900 to control. 16:25.899 --> 16:34.509 Even though among--Then another thing that happens, 16:34.509 --> 16:40.299 again just at this time, is that previously everybody-- 16:40.298 --> 16:42.768 the peasants had been in communes and I talked about them 16:42.774 --> 16:45.424 last time, several thousand families in 16:45.419 --> 16:47.479 one big farm, and under again, 16:47.482 --> 16:49.512 strict control of the government. 16:49.509 --> 16:52.659 Then with the Great Leap Forward they realized the 16:52.663 --> 16:56.143 commune system has failed and the land goes back to the 16:56.136 --> 16:58.836 people, they break up the communes and 16:58.839 --> 17:01.089 people get their own plot of land. 17:01.090 --> 17:04.340 They don't own it in our sense but they have the rights to work 17:04.343 --> 17:05.553 on that plot of land. 17:05.548 --> 17:08.898 Well they started growing their own food, private markets for 17:08.902 --> 17:11.312 food grow up, and the people are not getting 17:11.305 --> 17:13.815 everything they need from the government. 17:13.818 --> 17:16.778 If they really oppose some government policy then they can 17:16.777 --> 17:20.147 tell the government 'bye-bye,' I don't need anything from you, 17:20.150 --> 17:24.820 I'm now an independent farmer and I'll do what I want. 17:24.818 --> 17:29.688 The change to a market economy, that changed to more economic 17:29.692 --> 17:34.142 freedom for the individuals, led to all kinds of personal 17:34.141 --> 17:38.281 freedom and led to the ability to say no to the government. 17:38.279 --> 17:43.359 17:43.358 --> 17:44.688 At the time, in the press, 17:44.694 --> 17:47.744 there were all kinds of examples of what was going on, 17:47.740 --> 17:52.910 and for instance here's one article from 1980 again-- 17:52.910 --> 17:55.580 I'm sorry this is 2000. 17:55.578 --> 17:58.828 The one-child policy has been in effect for 20 years, 17:58.832 --> 18:02.272 "No one can accuse Huo Suifa of not knowing what he 18:02.271 --> 18:02.961 wanted. 18:02.960 --> 18:06.260 The 47-year-old farmer dreamed of having a son. 18:06.259 --> 18:11.629 After seven daughters he finally got a male heir in 1989. 18:11.630 --> 18:15.460 Ho named him Gaifeng, or 'change-in-the-weather,' and 18:15.463 --> 18:18.193 then he stopped having children," 18:18.192 --> 18:22.062 so seven daughters and a son, so this person--most--almost 18:22.055 --> 18:24.955 all of that time must have been under the one-child policy; 18:24.960 --> 18:27.130 eight children. 18:27.130 --> 18:30.510 He says, "It wasn't easy to have all these children, 18:30.505 --> 18:32.365 but it wasn't hard either," 18:32.374 --> 18:33.584 the farmer said. 18:33.578 --> 18:35.368 "If things became tough in our village, 18:35.368 --> 18:38.398 if there was a campaign to enforce the rule in their 18:38.403 --> 18:40.903 village" and China has these political 18:40.902 --> 18:44.062 campaigns to get people to change their behavior quite 18:44.055 --> 18:47.205 routinely at this time, "Well my wife just went to 18:47.211 --> 18:49.071 another township to have the child." 18:49.068 --> 18:53.328 What's the other side of the coin is this Huo now has a wife 18:53.334 --> 18:57.964 and eight children to support, and how much land does he have? 18:57.960 --> 19:03.600 One-third of an acre for eight, nine, ten people; 19:03.598 --> 19:08.338 this is not a good economic system, exactly why the 19:08.344 --> 19:11.574 one-child policy was instituted. 19:11.568 --> 19:14.138 An American misconception, fed by our press, 19:14.140 --> 19:17.010 is that China's government is very monolithic. 19:17.009 --> 19:20.899 The chairman in Peking or some bureaucrat says this is the 19:20.903 --> 19:23.093 rule, this is law, spells it out, 19:23.088 --> 19:25.478 everybody has to obey this law. 19:25.480 --> 19:30.060 Isn't the case; there's whole books now on how 19:30.056 --> 19:33.396 China is actually ruled, and the story is that the 19:33.403 --> 19:35.343 government almost gives a slogan, 19:35.338 --> 19:37.918 it's a one-child policy, or they sometimes call it the 19:37.924 --> 19:41.484 only child policy, is not a set of rules it's kind 19:41.483 --> 19:43.123 of almost a slogan. 19:43.118 --> 19:46.408 Then it goes down to the provinces, and each province has 19:46.413 --> 19:49.893 to determine in accord with local conditions as which is the 19:49.885 --> 19:51.705 official way of stating it. 19:51.710 --> 19:53.990 Then each province gives it down to the prefectures and the 19:53.989 --> 19:55.829 same thing, it's interpreted by 19:55.834 --> 19:59.724 local--under local conditions and then it goes down to the 19:59.718 --> 20:02.578 villages where it's completely changed. 20:02.578 --> 20:06.998 There's no--absolutely no uniformity from village to 20:07.001 --> 20:07.871 village. 20:07.868 --> 20:12.808 What that resulted in was the policy was never able to be 20:12.808 --> 20:15.718 consistently put into practice. 20:15.720 --> 20:19.690 The statistics give you the answer to that. 20:19.690 --> 20:23.230 The total fertility rate during this initial period of 20:23.226 --> 20:27.226 enforcement of the one-child policy never fell below two, 20:27.230 --> 20:31.290 so the policy was one child, but it never fell below two 20:31.288 --> 20:32.098 children. 20:32.098 --> 20:37.048 In the rural areas it never fell below 2.5. 20:37.048 --> 20:39.928 As you saw a couple of lectures ago, 20:39.930 --> 20:44.270 Qing showed you the one child certificate where the couple 20:44.266 --> 20:45.926 promises, it's just a promise, 20:45.929 --> 20:47.839 this doesn't say you've done it and this is just-- 20:47.838 --> 20:49.988 even to promise that you're only going to have one child, 20:49.990 --> 20:55.500 and less than 20% of married couples ever signed onto even 20:55.500 --> 20:58.980 that promise of having one child, 20:58.980 --> 21:01.830 which was telling the government, no we're not going 21:01.828 --> 21:03.448 to comply with this policy. 21:03.450 --> 21:07.150 Throughout the 1980s, which again was when the policy 21:07.150 --> 21:11.090 was strictly enforced, nearly half of all the births 21:11.087 --> 21:15.087 were second, third, or higher order births. 21:15.088 --> 21:17.908 Eighty percent of China's children had brothers or 21:17.914 --> 21:22.254 sisters, or both, many had both and only 21:22.247 --> 21:28.807 1/5th of the 300 million children under age 14 were from 21:28.807 --> 21:31.787 single child families. 21:31.788 --> 21:39.938 In 1986, again after the first--Question? 21:39.940 --> 21:43.210 Student: Would you say this is a result of inconsistent 21:43.208 --> 21:46.268 applications of the one-child policy or a reflection of the 21:46.265 --> 21:49.475 fact that the one-child policy was never (inaudible) one child 21:49.480 --> 21:51.220 and not in that urban area? 21:51.220 --> 21:53.700 Prof: Both, at this time initially it was 21:53.698 --> 21:56.808 supposed to be one child for all except minority people, 21:56.808 --> 21:59.608 so a very small part of the population. 21:59.608 --> 22:02.008 I'll tell you in a minute that--because of popular 22:02.008 --> 22:04.258 resistance they immediately loosened it up, 22:04.259 --> 22:09.289 so the main thing which you're probably referring to is that 22:09.289 --> 22:14.059 rather soon they said peasants-- the city people had already had 22:14.055 --> 22:15.375 their fertility drop. 22:15.380 --> 22:17.880 Many of them were not very interested in having more than 22:17.883 --> 22:18.423 one child. 22:18.420 --> 22:22.940 It was not a huge issue for you; one of your readings discusses 22:22.940 --> 22:23.410 that. 22:23.410 --> 22:25.590 In the countryside the peasants still wanted, 22:25.588 --> 22:27.688 certainly a son, more children, 22:27.692 --> 22:31.832 so the policy was changed rather rapidly so that if you-- 22:31.828 --> 22:35.298 if your first child is a daughter you can have another 22:35.295 --> 22:38.395 one and try for a boy, but two is the limit and of 22:38.403 --> 22:44.553 course two was not-- even that was not always 22:44.547 --> 22:46.627 observed. 22:46.630 --> 22:52.100 Remember I told you last time that the goal when the Chinese 22:52.095 --> 22:56.665 population crossed a billion, or looked like it was very 22:56.671 --> 23:00.241 close to crossing a billion, and the government sort of 23:00.242 --> 23:04.272 desperately wanted to keep the population below 1.2 billion in 23:04.265 --> 23:06.765 the year 2000 they didn't make it, 23:06.769 --> 23:09.149 the population was 1.3 billion. 23:09.150 --> 23:13.700 They missed by a 100 million and now it's considerably over 23:13.702 --> 23:17.082 that and the population is still growing. 23:17.078 --> 23:21.268 Because of population momentum, again the age structure of 23:21.268 --> 23:24.668 China, China's population is expected 23:24.672 --> 23:29.062 to grow by another 150 million people by 2025, 23:29.058 --> 23:32.338 so even though they've worked so hard and suffered so much 23:32.336 --> 23:35.436 under these various policies to restrict fertility, 23:35.440 --> 23:37.320 they're still going to increase from now, 23:37.318 --> 23:42.398 from 2008 to 2025 by half the total population of the United 23:42.404 --> 23:43.184 States. 23:43.180 --> 23:47.360 Again, comparable to a calculation I gave earlier, 23:47.358 --> 23:53.488 Hu Jintao, who was president of China recently says, 23:53.490 --> 23:58.060 the party plans to quadruple economic output per capita in 23:58.057 --> 23:59.017 that time. 23:59.019 --> 24:01.439 This was before the economic crash that has just happened. 24:01.440 --> 24:04.810 He wanted to quadruple the per capita income, 24:04.807 --> 24:09.397 which would still bring China up only to a low European level 24:09.401 --> 24:10.321 perhaps. 24:10.318 --> 24:16.498 With a 1.3 billion population, and you're quadrupling it, 24:16.500 --> 24:20.410 that's equal to 5.2 billion and the whole population of the 24:20.413 --> 24:24.533 earth is only 6.3, so you're talking about China's 24:24.534 --> 24:29.334 economic and population growth alone almost doubling the 24:29.333 --> 24:33.963 world's economic activity and therefore something like 24:33.957 --> 24:37.357 doubling the economic drain on it. 24:37.358 --> 24:41.618 China's TFR now, after this period of stability 24:41.622 --> 24:47.092 and after the marriage thing got settled it has drifted down 24:47.087 --> 24:50.977 slowly as almost all of the world has. 24:50.980 --> 24:54.670 It's now 1.6, it's still nowhere near one 24:54.673 --> 24:57.503 child per family, its 1.6 now, 24:57.498 --> 25:01.898 but that will eventually reduce the size of the Chinese 25:01.897 --> 25:04.667 population if it is maintained. 25:04.670 --> 25:11.080 What you should keep in mind is, this was the Chinese route 25:11.077 --> 25:13.507 to lower population. 25:13.509 --> 25:16.969 I described to you the population that they started 25:16.971 --> 25:21.061 with that was not paying any attention to individual desires 25:21.055 --> 25:24.995 in fertility and they brought it down by strong government 25:25.000 --> 25:27.740 policy, good amount of coercion and so 25:27.744 --> 25:28.164 forth. 25:28.160 --> 25:31.750 The Chinese populations around other parts of East Asia have 25:31.749 --> 25:35.099 lowered their birth rate even more, or I should say they 25:35.095 --> 25:37.495 started lower; they reached an even lower 25:37.497 --> 25:37.847 level. 25:37.849 --> 25:41.919 China is 1.6 as I told you; the Chinese population of 25:41.920 --> 25:44.570 Singapore is 1.4 children per women. 25:44.568 --> 25:47.618 The Japanese, who are not Chinese obviously, 25:47.623 --> 25:50.433 1.3; Taiwan 1.1; 25:50.430 --> 25:52.940 South Korea, again not Chinese, 25:52.938 --> 25:57.748 1.3; Hong Kong 1.0 and Macau 1.0. 25:57.750 --> 26:00.160 None of these places were under the one-child policy. 26:00.160 --> 26:02.140 Actually I'm not sure about Macau, but all the others are 26:02.137 --> 26:05.717 not under the one child policy, and they have a lower birth 26:05.722 --> 26:10.902 rate than the Chinese policy, and we'll have to discuss in a 26:10.903 --> 26:13.923 later lecture why this should be so. 26:13.920 --> 26:18.050 I'm going to finish up talking specifically about China to 26:18.053 --> 26:21.973 mention a little bit about economic globalization which 26:21.969 --> 26:23.709 you're all aware of. 26:23.710 --> 26:25.790 Because of globalization the U.S. 26:25.794 --> 26:28.014 and China are joined at the hip. 26:28.009 --> 26:32.819 For both our economies to succeed, we have to buy a lot of 26:32.816 --> 26:35.706 Chinese stuff, they have to buy our bonds, 26:35.714 --> 26:38.704 they keep their people employed by shipping us stuff, 26:38.700 --> 26:41.200 and we send them green paper back. 26:41.200 --> 26:45.000 The economics of this is quite crazy altogether because they 26:45.002 --> 26:47.242 can never use-- what's interesting is they 26:47.241 --> 26:49.571 basically can never use the money that we send them. 26:49.568 --> 26:52.628 That if--they have a trillion dollars or so in U.S. 26:52.628 --> 26:55.988 bonds and if they ever try to sell them the value of the 26:55.993 --> 26:59.853 dollar goes to zero and they have to sell them for nothing. 26:59.848 --> 27:02.028 That's a separate story, it's crazy. 27:02.028 --> 27:05.028 Lot of causes--reasons for globalization. 27:05.028 --> 27:07.998 Number one is shipping costs, the whole idea of the shipping 27:07.999 --> 27:11.619 when it went to containers, the cost of shipping something 27:11.623 --> 27:15.923 from China to the West Coast of America dropped drastically. 27:15.920 --> 27:18.530 Ships carry an awful lot, the water floats them across, 27:18.528 --> 27:21.778 and they just have to--the only energy that's used is to get 27:21.777 --> 27:24.747 over the friction of the water that they go through. 27:24.750 --> 27:28.920 Even many years ago I was in Bolivia discussing with an AID 27:28.921 --> 27:32.231 guy, Bolivia is very poor, what can they do? 27:32.230 --> 27:34.690 Well they have the mountains but then they have a jungle 27:34.694 --> 27:37.254 sloping down to the Amazon where they could grow rice, 27:37.250 --> 27:44.120 very good agricultural land, and why can't they give that to 27:44.123 --> 27:48.623 Lima or to La Paz, Lima and Peru where they're 27:48.615 --> 27:49.825 importing rice. 27:49.828 --> 27:52.678 The problem was that the Chinese can grow it in the 27:52.682 --> 27:55.402 Yangtze Valley, float it down the river to 27:55.395 --> 27:57.045 Shanghai, put it on a boat, 27:57.050 --> 27:59.210 and ship it and deliver it to Callao, 27:59.210 --> 28:01.680 Lima's port, cheaper than the Bolivians who 28:01.683 --> 28:04.633 are right next door to Peru can truck it over -- 28:04.630 --> 28:07.720 the Andes sort of go up and down and up again-- 28:07.720 --> 28:10.800 and down again and they have to ship it-- 28:10.798 --> 28:12.908 to get to the coast they have to ship it over two peaks of 28:12.912 --> 28:15.542 mountains on lousy roads, and trucking is just very 28:15.535 --> 28:16.355 inefficient. 28:16.358 --> 28:20.438 It's cheaper to get the thing from 15,000 miles away up in 28:20.439 --> 28:24.519 Sichuan than to get it next door from the Amazon slopes of 28:24.519 --> 28:26.579 Bolivia, so shipping costs is very 28:26.575 --> 28:27.065 important. 28:27.068 --> 28:29.808 For white collar jobs it's telecommunication. 28:29.808 --> 28:33.018 Now--we used to say let's let the low, 28:33.019 --> 28:37.819 the cheap labor manufacturing jobs go to China but now China 28:37.819 --> 28:41.199 and India we're in-- its immediate contact by 28:41.195 --> 28:45.225 telecommunications so the white collar jobs are going there. 28:45.230 --> 28:49.020 The engineering is going to India, the accounting is going 28:49.019 --> 28:52.009 to India, the call centers are going to India, 28:52.011 --> 28:54.541 and other jobs are going to China. 28:54.538 --> 29:01.028 This--what happens to population I think, 29:01.028 --> 29:04.268 in the long term view, and long terms means 25 or 50 29:04.268 --> 29:06.388 years, I'm not talking 1000 years, 29:06.393 --> 29:09.903 probably the one most important thing which will determine the 29:09.903 --> 29:10.943 future of the U.S. 29:10.938 --> 29:14.158 economy is what happens to population in China and India, 29:14.160 --> 29:17.440 and you can include Indonesia and the rest of Asia. 29:17.440 --> 29:21.550 As long as they have an incredible number of people 29:21.547 --> 29:25.747 willing to work for incredibly-- needing to work for incredibly 29:25.753 --> 29:27.893 low wages, we can't compete with them. 29:27.890 --> 29:31.730 There is no economic reason why an American should earn $40 a 29:31.729 --> 29:34.349 day or something like that, plus benefits, 29:34.352 --> 29:37.042 and that's a low wage for an American. 29:37.038 --> 29:41.738 Whereas, a third of China the per capita income is about $1 a 29:41.742 --> 29:46.292 day for the lowest third of China and that means the worker 29:46.289 --> 29:48.249 makes $2 or $3 a day. 29:48.250 --> 29:50.900 There's no way that we can earn, without benefits, 29:50.900 --> 29:54.260 that we can earn $40 or $80 depending on what you calculate 29:54.259 --> 29:57.389 and other people in the other world are earning $3, 29:57.390 --> 29:59.740 so jobs are going to continue to go to China; 29:59.740 --> 30:00.410 not only from the United States. 30:00.410 --> 30:01.680 They are leaving Mexico. 30:01.680 --> 30:05.110 I told you the story in Thailand, the jewelry business 30:05.112 --> 30:09.732 in Thailand that moved to China, that there's just this vast, 30:09.729 --> 30:14.509 vast sea of people who are desperate to work for basically 30:14.511 --> 30:15.521 $2 a day. 30:15.519 --> 30:18.479 A further thing happening, there are now a few 100 million 30:18.484 --> 30:20.414 people floating around the cities, 30:20.410 --> 30:22.280 migrant laborers trying to get jobs, 30:22.278 --> 30:24.498 and now with the current economic climate, 30:24.500 --> 30:28.120 being thrown out of jobs, but Chinese agriculture is 30:28.115 --> 30:29.885 incredibly inefficient. 30:29.890 --> 30:35.030 As I told you, the average farm size there is 30:35.029 --> 30:42.389 0.1 acre in China and that's just economically unsustainable. 30:42.390 --> 30:46.480 The average farm size in the world is--in Japan is 400 acres 30:46.484 --> 30:47.184 I think. 30:47.180 --> 30:49.450 No, I'm sorry in the world 400, in the U.S., 30:49.445 --> 30:50.285 an economic U.S. 30:50.288 --> 30:52.818 farm is like thousands of acres of big farms. 30:52.818 --> 30:55.308 We're talking about that, eventually China is going to 30:55.310 --> 30:57.710 have to compete in the agricultural world on an even 30:57.709 --> 30:59.589 footing with the rest of the world, 30:59.588 --> 31:01.878 which means their farms are going to have to combine. 31:01.880 --> 31:03.770 That's already happening. 31:03.769 --> 31:06.479 People are voluntarily sort of pooling their land, 31:06.480 --> 31:09.670 having big things--enough of the land to be-- 31:09.670 --> 31:11.710 to make it worth them to buy a tractor and so forth, 31:11.710 --> 31:14.930 so this economic rationalization of agriculture 31:14.930 --> 31:15.980 is happening. 31:15.980 --> 31:21.810 Think of the numbers there, you have 800 million peasants 31:21.805 --> 31:23.985 with 0.1 acre each. 31:23.990 --> 31:27.860 When you combine it even to 100 acre farm, which is still a 31:27.855 --> 31:31.785 small farm worldwide that means you combined 1000 farms into 31:31.786 --> 31:32.316 one. 31:32.318 --> 31:37.708 In the modern world 100 acres is probably farmed by one or two 31:37.714 --> 31:41.174 people, so you go from 1000 families 31:41.173 --> 31:47.063 living on 0.1 acre each to maybe two families living on 100 acres 31:47.057 --> 31:49.077 of a combined farm. 31:49.078 --> 31:52.978 That means that something like 99% of the population of the 31:52.976 --> 31:55.996 countryside has to get jobs somewhere else. 31:56.000 --> 32:00.270 If you have 800 million peasants, almost 800 million new 32:00.265 --> 32:04.685 people are waiting for these economic changes to come onto 32:04.685 --> 32:10.455 the modern job market, and so there are a vast number 32:10.458 --> 32:14.758 of people waiting, that are now competing with us 32:14.757 --> 32:17.587 and every other industrial advanced country, 32:17.588 --> 32:20.548 and who will continue to compete with us. 32:20.548 --> 32:23.528 The Chinese government is well aware, of course, 32:23.530 --> 32:24.800 of all this stuff. 32:24.798 --> 32:28.338 In October last year, previously I-- 32:28.338 --> 32:31.358 they don't really own their land and they still don't, 32:31.358 --> 32:34.878 but they what they call a land reform and the plan allows 32:34.878 --> 32:38.708 farmers for the first time to lease or transfer their land use 32:38.712 --> 32:40.412 rights to someone else. 32:40.410 --> 32:43.320 Basically the Chinese are now allowed to sell their farm, 32:43.318 --> 32:45.668 which will ease--now they have to have very complicated 32:45.673 --> 32:48.073 collective arrangements where everybody is sort of still 32:48.069 --> 32:50.659 there, but once you can basically sell 32:50.659 --> 32:53.109 or alienate your land in some way, 32:53.108 --> 32:57.888 than you can totally leave the land and go into the cities. 32:57.890 --> 33:02.160 The government has started encouraging this kind of push. 33:02.160 --> 33:07.260 What they'll do now, with the economic collapse, 33:07.260 --> 33:08.890 I don't know. 33:08.890 --> 33:14.040 It's--we have a long way to go before the population issue in 33:14.036 --> 33:19.096 China is settled and our fate and all of the developed world 33:19.097 --> 33:23.127 depends very much on what happens in China. 33:23.130 --> 33:26.950 Just to finish, the Chinese have--the 33:26.952 --> 33:31.732 achievement of China is just mind boggling. 33:31.730 --> 33:35.730 that In a half a century they took people from an extremely 33:35.734 --> 33:39.604 poor country, devastated by over 100 years of 33:39.596 --> 33:41.976 war, and now it's becoming one of 33:41.976 --> 33:44.676 the first ranked countries in the world. 33:44.680 --> 33:47.490 Before this all started, no one would have thought this 33:47.489 --> 33:48.269 was possible. 33:48.269 --> 33:51.019 If you can read the literature of that time, 33:51.017 --> 33:52.357 China was hopeless. 33:52.358 --> 33:55.398 With respect to fertility, which you'll see is a very 33:55.397 --> 33:58.727 important part of the whole story of economic success, 33:58.730 --> 34:01.890 their decline, the rapidity of their decline 34:01.891 --> 34:06.381 to get a country like China to drop its fertility in ten years 34:06.375 --> 34:13.405 is just an amazing achievement; just incredible. 34:13.409 --> 34:23.189 Now, we want to get onto this next question that a student 34:23.190 --> 34:26.280 asked last time. 34:26.280 --> 34:29.310 When I was saying the Chinese--remember the Chinese 34:29.313 --> 34:32.533 started this population thing for economic reasons. 34:32.530 --> 34:38.040 They said--our economy is going along, 34:38.039 --> 34:39.459 we're increasing, like I said, 34:39.456 --> 34:41.946 agricultural production what was it 2.5% a year, 34:41.949 --> 34:44.699 which was very good -- but population is growing 2.3% a 34:44.702 --> 34:46.512 year, so we're not helping the people. 34:46.510 --> 34:52.280 It was very overtly stated that the one-child policy was to 34:52.275 --> 34:54.855 improve China's economy. 34:54.860 --> 34:57.660 They wanted to improve the standard of living of the 34:57.655 --> 34:58.145 people. 34:58.150 --> 35:00.490 At the time, when they started this policy, 35:00.489 --> 35:02.939 the standard of living in China was very low, 35:02.942 --> 35:05.062 and I don't have to tell you that. 35:05.059 --> 35:08.779 Healthcare was very--was certainly better than it had 35:08.784 --> 35:11.224 been but still a very low level. 35:11.219 --> 35:15.629 Education was not widely available below the very early 35:15.634 --> 35:17.764 primary grades in China. 35:17.760 --> 35:20.760 Basically, as the Chinese perceived it themselves, 35:20.759 --> 35:24.369 and as they talked about it quite a bit, their children were 35:24.371 --> 35:26.821 growing up unhealthy and uneducated. 35:26.820 --> 35:31.250 When the Chinese talk about economic development, 35:31.250 --> 35:34.130 it's not only manufacturing more stuff which they basically 35:34.130 --> 35:36.800 are not too interested in, they ship it to America. 35:36.800 --> 35:39.140 They were primarily interested in what they called the quality 35:39.143 --> 35:39.763 of the people. 35:39.760 --> 35:43.460 They thought their population was not of the quality that they 35:43.458 --> 35:46.428 wanted, and quality means health and education. 35:46.429 --> 35:50.739 They wanted--their children were growing up not healthy and 35:50.739 --> 35:53.139 not educated, and they like everyone in the 35:53.143 --> 35:55.153 world, realizes that uneducated, 35:55.150 --> 35:58.900 sick children, and sick adults don't--are not 35:58.900 --> 36:00.420 very productive. 36:00.420 --> 36:03.070 Western economists, for a long time, 36:03.070 --> 36:06.920 considered capitalist--physical capital your factories and 36:06.916 --> 36:11.026 machines that you have and the idea of human-capital is fairly 36:11.032 --> 36:14.412 recent and has now come massively into vogue in the 36:14.407 --> 36:15.147 West. 36:15.150 --> 36:17.660 That one of the most important determinants of the wealth of a 36:17.657 --> 36:19.617 country, why is one country rich and one 36:19.619 --> 36:23.149 country poor is not resources, is not your physical capital 36:23.148 --> 36:25.608 base, but your human capital base. 36:25.610 --> 36:28.600 Partly we've learned that from the Chinese. 36:28.599 --> 36:32.499 I mean we learned it ourselves but also the Chinese examples 36:32.498 --> 36:34.678 were very good example of this. 36:34.679 --> 36:39.309 Just to give you an example of what happens when people don't 36:39.309 --> 36:41.869 have education, in this particular case 36:41.869 --> 36:45.799 biological education, is a story from again the year 36:45.804 --> 36:48.934 2000-- again not that many years back. 36:48.929 --> 36:53.959 This is from Du who was a local official in a small village. 36:53.960 --> 36:57.470 He said, "One day there were hundreds of people lined up 36:57.469 --> 37:01.029 at the entrance of our village, I thought it must be a 37:01.027 --> 37:03.807 vegetable market or a movie coming in. 37:03.809 --> 37:05.949 It turned out to be blood selling. 37:05.949 --> 37:09.239 I felt so terrified because there was no sterilization 37:09.244 --> 37:10.804 equipment at all." 37:10.800 --> 37:14.520 This village official had some education, he understood about 37:14.519 --> 37:18.119 sterilization and he had seen these blood campaigns before, 37:18.117 --> 37:19.417 no sterilization. 37:19.420 --> 37:23.350 "Villagers just tell the traffickers their blood type, 37:23.351 --> 37:26.201 if they know it, if not they make it up. 37:26.199 --> 37:29.249 The villagers just tell the traffickers their blood type and 37:29.246 --> 37:31.826 then lie die on the ground to offer blood." 37:31.829 --> 37:34.109 What is the result of this? 37:34.110 --> 37:37.690 A vast AIDS epidemic in these rural villages that were doing 37:37.693 --> 37:39.573 this, because they use the same 37:39.572 --> 37:42.862 needle to repeatedly take blood from person after person, 37:42.860 --> 37:44.770 they line up on the ground and they stick one needle, 37:44.766 --> 37:45.386 take the blood. 37:45.389 --> 37:48.459 Needles are so expensive, the apparatus for collecting it 37:48.458 --> 37:50.598 is expensive, and so they reuse the same 37:50.597 --> 37:51.197 needle. 37:51.199 --> 37:56.009 Of course when you use the same needle from person to person the 37:56.012 --> 38:00.602 odds are if one person gets it the next ones are going to get 38:00.597 --> 38:02.747 it, but actually the transmission 38:02.748 --> 38:05.988 rate by blood to blood contact by a needle is something like 1 38:05.985 --> 38:08.325 in 200, it's not terribly efficient. 38:08.329 --> 38:11.059 What do they do with the blood? 38:11.059 --> 38:12.959 They collect blood from everybody, then instead of 38:12.960 --> 38:14.990 keeping it individually, which is expensive, 38:14.990 --> 38:17.240 they dump it into a big vat, they pool it, 38:17.235 --> 38:19.905 they take it to the city, they extract the components 38:19.909 --> 38:21.959 that they want which is the gamma globulin, 38:21.960 --> 38:24.510 the clotting factor, and a few other components and 38:24.505 --> 38:26.385 then they have a lot of blood left. 38:26.389 --> 38:27.239 What do they do? 38:27.239 --> 38:30.279 They go back to the village and re-inject the blood, 38:30.277 --> 38:32.537 the remaining blood into the people. 38:32.539 --> 38:34.309 Now you don't just have a needle stick, 38:34.309 --> 38:37.779 you've got a pint of someone else--of a mixed blood of 38:37.775 --> 38:40.975 everyone in the village going into your veins, 38:40.980 --> 38:44.630 and now for sure if anyone in the village has AIDS you're 38:44.628 --> 38:46.648 going to be infected with it. 38:46.650 --> 38:49.110 Du continued, "The villagers become 38:49.110 --> 38:52.460 crazy about selling blood because they are so poor and 38:52.456 --> 38:53.716 life is so hard. 38:53.719 --> 38:57.389 Many had built their houses by selling blood. 38:57.389 --> 39:00.339 Some will even bribe traffickers to be able to sell 39:00.338 --> 39:02.048 more than once a day." 39:02.050 --> 39:04.160 The traffickers are interested in giving them back blood 39:04.157 --> 39:05.687 because then they'll make more blood, 39:05.690 --> 39:09.470 they can sell more blood again, but the people want to sell 39:09.472 --> 39:13.222 more than a pint in each day, so they kind of lie and fake 39:13.224 --> 39:14.714 because they're so poor. 39:14.710 --> 39:17.750 39:17.750 --> 39:21.640 The officials estimate something like 600,000 HIV 39:21.641 --> 39:25.371 cases, that's probably nowhere near correct. 39:25.369 --> 39:29.169 The blood collections, starting in the 1990s, 39:29.168 --> 39:32.448 were protected by corrupt officials. 39:32.449 --> 39:34.769 This was of course against public policy, 39:34.768 --> 39:38.358 but it may have infected a million people, 39:38.360 --> 39:41.220 this blood selling in Henan Province, 39:41.219 --> 39:45.599 especially and virtually all of them poor peasants who sold the 39:45.596 --> 39:47.146 blood to make money. 39:47.150 --> 39:54.140 That gives you an idea again of the status of education of the 39:54.143 --> 40:00.683 population and why human capital is so very important, 40:00.679 --> 40:03.689 because you're collecting blood to sell to hospitals, 40:03.690 --> 40:06.080 which will improve the health of presumably of some people who 40:06.077 --> 40:08.457 receive the blood, but not if they get AIDS. 40:08.460 --> 40:14.620 While you're helping a few people with transfusions you're 40:14.615 --> 40:20.445 infecting millions of people with AIDS so you're making 40:20.449 --> 40:23.149 things totally worse. 40:23.150 --> 40:27.160 Does cutting your population--so China had the 40:27.155 --> 40:30.795 idea, not alone, that if they reduce their 40:30.804 --> 40:35.614 population growth rate their economy will improve. 40:35.610 --> 40:39.200 Is this true? 40:39.199 --> 40:43.049 Most economists, at the time, 40:43.047 --> 40:47.307 would certainly have said no. 40:47.309 --> 40:52.449 That's a Malthusian idea that population-- 40:52.449 --> 40:56.879 that economic development is limited by population growth and 40:56.880 --> 41:00.790 people thought that the industrial revolution had sort 41:00.793 --> 41:04.133 of gotten rid of Malthus, Malthus was irrelevant. 41:04.130 --> 41:06.590 Marx, as I mentioned last time, hated Malthus. 41:06.590 --> 41:11.090 Marx was totally opposed and so a lot of the world's opinion was 41:11.088 --> 41:15.658 that no, population growth was not detrimental to the economy. 41:15.659 --> 41:20.089 In fact, they believed that population growth was good for 41:20.092 --> 41:23.672 an economy because it increased the market, 41:23.670 --> 41:25.180 and everybody wants to increase the market, 41:25.179 --> 41:30.339 and you can get efficiencies of scale for all kinds of reasons, 41:30.340 --> 41:33.100 a growing population was considered to be a wonderful 41:33.103 --> 41:33.533 thing. 41:33.530 --> 41:35.820 Businessmen, especially in the capitalist 41:35.824 --> 41:38.424 economies, love population growth because 41:38.418 --> 41:40.758 the population of the United States, 41:40.760 --> 41:43.120 for instance, is now growing at 1% a year, 41:43.119 --> 41:46.869 which is less than it had been, it had been 1.5% or so. 41:46.869 --> 41:51.359 The economic growth rate is about 3%, at best in a very good 41:51.360 --> 41:53.720 year, in a good year it's 3%. 41:53.719 --> 41:59.449 Population growth at 1% or 1.5%, if your total economy is 41:59.454 --> 42:03.574 growing at 2% or 3%, population growth is half the 42:03.570 --> 42:07.090 increase in gross national product and that means it's half 42:07.092 --> 42:08.432 of company profits. 42:08.429 --> 42:11.959 When you have General Motors, it was counting every year on 42:11.963 --> 42:15.683 population growing and being able to sell more automobiles. 42:15.679 --> 42:21.519 That was basically the idea that population growth was not a 42:21.521 --> 42:22.711 bad thing. 42:22.710 --> 42:29.460 In 1958 two American demographer economists had a 42:29.458 --> 42:31.848 different idea. 42:31.849 --> 42:35.909 They looked at the developing countries, which had enormous 42:35.914 --> 42:40.264 population and very high growth rates and they weren't doing so 42:40.259 --> 42:40.889 well. 42:40.889 --> 42:42.759 What's with this theory? 42:42.760 --> 42:46.260 They should be doing wonderfully, they should be 42:46.255 --> 42:49.275 improving tremendously, and they came up with a 42:49.280 --> 42:52.170 different understanding of the relationship between population 42:52.172 --> 42:52.982 and economics. 42:52.980 --> 42:55.940 This is based on some very simply economics. 42:55.940 --> 43:00.090 That economic development requires investment. 43:00.090 --> 43:01.990 If you want to produce something you've got to build a 43:01.994 --> 43:03.114 factory and that takes money. 43:03.110 --> 43:04.390 Where does that money come from? 43:04.389 --> 43:06.379 That comes from someone else saving. 43:06.380 --> 43:09.820 Someone earns some money, by his labor or by whatever, 43:09.824 --> 43:12.594 earns some money; he can either spend that right 43:12.585 --> 43:15.375 away or he can put it in the bank and then the bank will 43:15.380 --> 43:18.380 invest it for him, or he can put it into stocks or 43:18.382 --> 43:19.662 something like that. 43:19.659 --> 43:23.799 Investment in a country, within some kind of economy, 43:23.800 --> 43:26.190 investment requires savings. 43:26.190 --> 43:30.570 One person has to save so another can spend it as an 43:30.568 --> 43:33.228 investment, they borrow that. 43:33.230 --> 43:38.570 43:38.570 --> 43:42.920 That's the key idea in everything that follows. 43:42.920 --> 43:47.060 What Coale and Hoover realized is that if you have-- 43:47.059 --> 43:49.699 if a family has a lot of children, if all the workers are 43:49.704 --> 43:51.504 married and have a lot of children, 43:51.500 --> 43:54.800 all of their income goes for food, clothing, 43:54.800 --> 43:57.220 and shelter to support the children. 43:57.219 --> 43:58.809 They can't save any money. 43:58.809 --> 44:02.409 If a country has no savings, they don't have any money to 44:02.405 --> 44:05.485 invest, they don't make any economic progress. 44:05.489 --> 44:09.659 This had a big political effect, this theory. 44:09.659 --> 44:12.639 It seems so simple and so obvious but it-- 44:12.639 --> 44:15.289 apparently they had good empirical support, 44:15.289 --> 44:17.859 they studied Mexico and a couple of other countries, 44:17.860 --> 44:21.810 and showed that this really seemed to be the case. 44:21.809 --> 44:25.409 Well at that time the third world was--the population 44:25.407 --> 44:28.937 explosion was happening, they were desperately poor, 44:28.936 --> 44:31.216 and so there were two groups. 44:31.219 --> 44:35.529 One, conservatives were at that time worried about the Cold War. 44:35.530 --> 44:39.930 America was locked in the Cold War with communists and China, 44:39.931 --> 44:44.481 Russia, but especially Russia was our big enemy at the time. 44:44.480 --> 44:46.900 We saw that all these desperately poor countries, 44:46.900 --> 44:49.590 the governments were not--their current economic and political 44:49.585 --> 44:51.605 systems were not giving them what they want. 44:51.610 --> 44:54.750 They were poor and getting poorer as they perceived it, 44:54.750 --> 44:57.090 and they were trying out all kinds of different political 44:57.086 --> 44:59.156 solutions, some of which were leftist. 44:59.159 --> 45:02.739 In America, there was a big push by conservatives, 45:02.739 --> 45:06.679 by the anti-communists, to do something about the third 45:06.684 --> 45:09.464 world to save them from communism. 45:09.460 --> 45:13.830 Meanwhile, the liberals were less involved in this us versus 45:13.827 --> 45:16.777 them kind of controversy, but they saw all these poor 45:16.782 --> 45:18.782 people in the world and wanted to help all the poor people, 45:18.780 --> 45:21.320 so they thought we should do something about all these poor 45:21.320 --> 45:22.980 people, and the answer was economic 45:22.981 --> 45:23.571 development. 45:23.570 --> 45:28.230 Economic development was universally approved in America 45:28.228 --> 45:31.308 by everyone, as either benevolent act by 45:31.311 --> 45:34.531 someone who considered themselves liberal or by a 45:34.532 --> 45:38.292 self-serving anti-communist act by someone who considered 45:38.291 --> 45:40.171 himself a conservative. 45:40.170 --> 45:45.720 Well, once the Coale/Hoover paper came out and people 45:45.721 --> 45:50.121 started realizing the-- what was considered to be the 45:50.117 --> 45:53.547 obvious at that time, it was very clear that family 45:53.545 --> 45:57.795 planning programs had to be a part of economic development. 45:57.800 --> 46:00.840 That these countries just--with these booming populations and 46:00.842 --> 46:03.432 there were televisions full of stories of India, 46:03.429 --> 46:05.449 and how it was starving people in India. 46:05.449 --> 46:08.159 China was kind of closed to us at that time, 46:08.159 --> 46:10.989 but India was open, but a desperate situation that 46:10.990 --> 46:14.400 was in India and India had quite leftist governments and was 46:14.400 --> 46:16.540 India going to go communist, etc. 46:16.539 --> 46:20.799 Both sides of the--the whole political spectrum believed in 46:20.800 --> 46:25.430 economic aid to the developing world and family planning aid. 46:25.429 --> 46:28.639 It turns out that George Bush, the senior, 46:28.639 --> 46:31.019 the first George Bush President, when he was a 46:31.021 --> 46:33.771 congressman was one of the sponsors of the very first 46:33.773 --> 46:36.893 family planning bill, not only for domestic family 46:36.889 --> 46:39.929 planning but also the international aid for family 46:39.934 --> 46:40.684 planning. 46:40.679 --> 46:44.179 This was not a debatable issue, everybody agreed with it, 46:44.179 --> 46:47.739 and it was really due to this economic thesis by Coale and 46:47.742 --> 46:48.432 Hoover. 46:48.429 --> 46:51.459 You've read some of Ansley Coale's stuff already. 46:51.460 --> 46:54.710 Now, however, the economists keep working, 46:54.710 --> 47:18.010 the scholars keep going--what they did is they looked cross 47:18.005 --> 47:33.265 nationally and tried to figure out, 47:33.268 --> 47:39.138 is it really true that population growth rate would 47:39.137 --> 47:42.657 affect GDP, the growth of gross domestic 47:42.664 --> 47:45.334 product per capita, it's basically per capita 47:45.329 --> 47:45.729 income. 47:45.730 --> 47:48.320 What did they find when they got all the countries they could 47:48.317 --> 47:49.177 find in the world? 47:49.179 --> 47:52.629 Here's the growth rate and here's per capita economic 47:52.632 --> 47:53.232 growth. 47:53.230 --> 47:56.450 What's the pattern? 47:56.449 --> 48:01.649 Zero, there is no pattern here, so it looks like that this--it 48:01.646 --> 48:03.176 was meaningless. 48:03.179 --> 48:07.329 That in fact the Coale/Hoover hypothesis was wrong, 48:07.327 --> 48:11.967 and however nice the theory seemed, you just couldn't get 48:11.971 --> 48:14.461 empirical evidence for it. 48:14.460 --> 48:18.100 That was terribly important, again a reversal, 48:18.099 --> 48:21.779 now the Reagan Administration comes in and on the basis of 48:21.782 --> 48:26.802 information like that says, economic population control is 48:26.797 --> 48:30.487 no benefit to an economy's growth, 48:30.489 --> 48:33.089 and we, as conservatives, are opposed to government 48:33.092 --> 48:35.542 intervention in the private lives of people, 48:35.539 --> 48:39.339 so we're opposed to--we're not going to give out the-- 48:39.340 --> 48:43.140 anywhere near the level of family planning aid that we used 48:43.141 --> 48:43.471 to. 48:43.469 --> 48:46.469 The United States went from a big leader in funding family 48:46.474 --> 48:49.324 planning programs in the rest of the world to trying to 48:49.320 --> 48:50.270 discourage it. 48:50.268 --> 48:53.428 We didn't drop to zero, there were still programs that 48:53.427 --> 48:56.047 we funded and they were very good by AID, 48:56.050 --> 48:58.800 but we were the main discourager in the world, 48:58.800 --> 49:00.910 we didn't like this whole idea. 49:00.909 --> 49:06.429 What came up as--in opposition to this, 49:06.429 --> 49:09.429 and there was a big World Congress about population and 49:09.431 --> 49:13.361 development in Bucharest, Romania at the time, 49:13.364 --> 49:20.494 and the kind of data that came out in this period is they-- 49:20.489 --> 49:25.069 they came out with the idea that the way to get-- 49:25.070 --> 49:27.980 that it is good to have fertility down for a lot of 49:27.983 --> 49:31.013 reasons but the way to do it, that the causality, 49:31.014 --> 49:34.764 the Coale/Hoover causality is a reduction in population growth 49:34.757 --> 49:37.087 will lead to economic development, 49:37.090 --> 49:42.570 that the idea of the reverse causality that an increase in 49:42.570 --> 49:48.340 economic development will lead to a decrease in fertility. 49:48.340 --> 49:53.610 The slogan that came out of this Bucharest meeting of all 49:53.612 --> 49:57.092 the world leaders, is that development was the 49:57.090 --> 49:59.550 best contraceptive, that if you wanted to lower 49:59.550 --> 50:02.980 birth rates, what you had to focus on was 50:02.980 --> 50:05.150 economic development. 50:05.150 --> 50:09.020 And that became the mantra for the world and the developing 50:09.016 --> 50:10.946 countries bought into that. 50:10.949 --> 50:14.459 It was very interesting because just at that time Romania, 50:14.460 --> 50:17.710 the host of this meeting, was having the most extreme 50:17.710 --> 50:21.220 family planning program ever, but in the opposite direction. 50:21.219 --> 50:24.639 They, at that time, it was a Soviet block country 50:24.635 --> 50:27.335 that was doing poorly economically, 50:27.340 --> 50:30.980 their birth rate was very low, their mechanism of birth 50:30.978 --> 50:34.968 control was abortion; 4 out of 5 pregnancies were 50:34.972 --> 50:38.232 terminated by abortions in Romania. 50:38.230 --> 50:42.000 For every one child-birth, there were four abortions. 50:42.000 --> 50:45.240 Romania, not for economic reasons, but for nationalist 50:45.237 --> 50:48.967 reasons, they wanted a bigger stronger Romania so they clamped 50:48.965 --> 50:50.305 down tremendously. 50:50.309 --> 50:51.989 Abortion completely de-legalized, 50:51.990 --> 50:54.250 you couldn't get contraceptives anymore, 50:54.250 --> 50:59.800 and the end result was that the birth rate temporarily fell but 50:59.797 --> 51:04.987 then the women established networks of illegal abortion and 51:04.985 --> 51:10.085 gradually the birth rate rose because they didn't have any 51:10.085 --> 51:12.915 means, but very rapidly within a year 51:12.918 --> 51:15.918 or a two they established illegal abortion networks and 51:15.922 --> 51:17.482 the birth rate came down. 51:17.480 --> 51:20.210 It never came down to its original level and there's 51:20.210 --> 51:23.050 actually a fairly big total effect of their policy. 51:23.050 --> 51:29.590 It was just the political chicanery going on that here, 51:29.590 --> 51:32.630 Ceausescu, who was running Romania as a very strong 51:32.630 --> 51:35.830 communist dictator, was doing a very strong 51:35.827 --> 51:39.147 pronatalist family policy, but saying no, 51:39.152 --> 51:42.542 the opposite won't work; you have to go through economic 51:42.536 --> 51:43.156 development. 51:43.159 --> 51:49.729 Then people went to work on that theory and here's the data, 51:49.730 --> 51:53.730 that in this period of time, these are the countries with 51:53.731 --> 51:58.161 slow economic growth and their population growth rate was about 51:58.164 --> 52:02.314 2.7% and here's the ones with fast economic growth rate and 52:02.309 --> 52:04.969 their-- fast economic growth and 52:04.965 --> 52:08.415 they're the same in terms of population growth. 52:08.420 --> 52:11.320 Here's your look some years later and you have the same 52:11.317 --> 52:13.297 story, those with slow economic 52:13.304 --> 52:17.254 growth, those with fast economic growth have the same population 52:17.253 --> 52:17.883 growth. 52:17.880 --> 52:23.160 It is not true that development itself acts as a contraceptive. 52:23.159 --> 52:26.059 You look at it, you spin the data, 52:26.059 --> 52:30.849 the same data but differently, you look at those countries 52:30.847 --> 52:35.297 which have slow population growth which are these, 52:35.300 --> 52:37.520 and while it wasn't--or fast population growth-- 52:37.518 --> 52:40.688 and you ask, is that affecting GDP? 52:40.690 --> 52:44.760 And you're not seeing a big effect here in this time frame. 52:44.760 --> 52:49.470 But you are seeing a big time effect in this time frame. 52:49.469 --> 52:51.599 Now something different is going on, 52:51.599 --> 52:55.329 here those countries with slow population growth are increasing 52:55.327 --> 52:57.767 economically, those countries with fast 52:57.768 --> 53:00.548 population growth are decreasing economically. 53:00.550 --> 53:02.670 The funny thing about this graph, you say well it's the 53:02.670 --> 53:04.790 same data, how can you come to opposite conclusions? 53:04.789 --> 53:07.099 It's not, the same data spun differently. 53:07.099 --> 53:12.769 This is the population growth rate in 1965 to 1980 and then 53:12.773 --> 53:18.843 the economic situation 25 years later, 15 to 25 years later. 53:18.840 --> 53:22.700 So something it looks like from--This is not wildly 53:22.695 --> 53:25.835 conclusive data, but something about population 53:25.835 --> 53:29.125 growth, much later, has an effect on 53:29.134 --> 53:31.334 your economic growth. 53:31.329 --> 53:35.589 That's what has now been figured out to be exactly the 53:35.585 --> 53:40.235 really important relationship between population growth and 53:40.242 --> 53:42.252 economic development. 53:42.250 --> 53:44.640 You've seen this graph many, many times. 53:44.639 --> 53:47.799 This is the standard demographic transition where the 53:47.797 --> 53:50.797 mortality rate, the death rate falls first, 53:50.800 --> 53:55.120 then after some delay the birth rate falls and your population 53:55.117 --> 53:59.507 growth rate is this period when the birth rate is way above the 53:59.507 --> 54:00.637 death rate. 54:00.639 --> 54:05.089 Another aspect of that, here's the same graph again up 54:05.090 --> 54:09.790 here, is that if you ask what does the share working look 54:09.793 --> 54:10.553 like? 54:10.550 --> 54:12.430 How many of these people are working? 54:12.429 --> 54:16.449 You have an idea called the 'dependency ratio' which is your 54:16.445 --> 54:19.365 number of workers, divided by your number of 54:19.371 --> 54:22.231 children and your number of old folks. 54:22.230 --> 54:25.480 Well in developing countries the medical care is bad so you 54:25.476 --> 54:28.446 don't have-- you can almost ignore the old 54:28.447 --> 54:31.087 folks for quite a period of time, 54:31.090 --> 54:33.230 so basically the workers divided by the number of 54:33.228 --> 54:33.718 children. 54:33.719 --> 54:42.909 What happens during this period is that as the fertility rate 54:42.905 --> 54:50.095 falls what happens is you have a population-- 54:50.099 --> 54:52.939 we've seen the population pyramid for that with a number 54:52.938 --> 54:55.828 of workers in the middle and then many more children than 54:55.829 --> 54:58.479 workers, half again as many children as 54:58.480 --> 55:00.660 workers, so each worker has to 55:00.659 --> 55:04.859 support--each person in working age has to support 1.5 or 2 55:04.858 --> 55:07.028 children of children's age. 55:07.030 --> 55:10.140 Then you get this fantastic fertility drop, 55:10.144 --> 55:13.934 as we saw in places like China, where, in ten years, 55:13.929 --> 55:17.489 the fertility comes down, and what happened? 55:17.489 --> 55:20.999 This is the big population of people at that age, 55:20.998 --> 55:24.288 and there's no children coming behind them. 55:24.289 --> 55:27.549 Kids are born, you have a very high 55:27.547 --> 55:29.827 population, kids are born, 55:29.833 --> 55:33.613 then all of a sudden the population stops having children 55:33.606 --> 55:35.676 basically, it drops tremendously, 55:35.679 --> 55:37.939 but you still have all these children born. 55:37.940 --> 55:41.510 It takes 15,20 years for them to get into working age, 55:41.510 --> 55:46.040 so once you drop your fertility you see no effect then because 55:46.041 --> 55:50.201 you still have to support all those children for the next 55:50.201 --> 55:51.391 15,20 years. 55:51.389 --> 55:55.149 It's only after delay of 15 to 20 years that you have this huge 55:55.146 --> 55:57.326 number of people in working ages, 55:57.329 --> 56:02.129 very few children behind them, and the ratio of workers to 56:02.128 --> 56:04.738 dependents becomes very good. 56:04.739 --> 56:07.909 This is the--the people inside the snake. 56:07.909 --> 56:10.789 That's a takeoff on another 'you are here' graph that I 56:10.788 --> 56:13.878 showed you of the population growth, anyway forget that. 56:13.880 --> 56:18.610 Here is--you've seen this for China but here's for all of East 56:18.606 --> 56:22.946 Asia, this is the death rate and the death rate is really 56:22.947 --> 56:25.037 basically down by 1970. 56:25.039 --> 56:28.519 I've showed you that for Egypt and all around the world that 56:28.521 --> 56:31.951 the mortality rate comes down fast and then doesn't make an 56:31.945 --> 56:34.125 awful lot of progress since then. 56:34.130 --> 56:36.450 This is people aging, so this is where we are now, 56:36.449 --> 56:39.889 about 2009, so this stuff is all guessing about the future 56:39.887 --> 56:43.147 but basically since 1970 the death rate has been pretty 56:43.146 --> 56:45.736 constant but the birth rate comes down. 56:45.739 --> 56:48.909 This big drop in 1970s, again this is all of East Asia 56:48.914 --> 56:52.754 but primarily what you're seeing is China's big drop in the death 56:52.750 --> 56:55.010 rate, and so population growth 56:55.010 --> 56:57.850 narrows, narrows down to almost nothing. 56:57.849 --> 57:02.629 Presumably in the near future the death rate will climb above 57:02.634 --> 57:03.994 the birth rate. 57:03.989 --> 57:07.709 In looking at age structure, this is kind of a complicated 57:07.706 --> 57:09.726 graph, but they're very cute. 57:09.730 --> 57:13.330 This is Sub-Saharan Africa as a comparison, this is an opposite 57:13.331 --> 57:14.031 situation. 57:14.030 --> 57:16.070 Here this is like a piece of a pyramid; 57:16.070 --> 57:17.350 this is your age group. 57:17.349 --> 57:21.499 Here you have very few old people, here you have-- 57:21.500 --> 57:26.060 in 1950 this stripe is for the year 1950 very few oldsters, 57:26.059 --> 57:29.809 this is your working age population in here say from 20 57:29.806 --> 57:32.926 to 60 or whatever numbers you want to put, 57:32.929 --> 57:35.869 and there's more children in any age group than any of them. 57:35.869 --> 57:38.239 You've seen the population pyramid like that. 57:38.239 --> 57:41.539 Now as time goes on, in a place like Sub-Saharan 57:41.538 --> 57:45.678 Africa that does not go through fertility transition is that 57:45.677 --> 57:50.377 this shape of more children than oldsters just continues 1975, 57:50.380 --> 57:52.290 2000,2025. 57:52.289 --> 57:56.639 You begin to see the--they hope again--This is where we are now; 57:56.639 --> 57:58.359 this is all guessing about the future. 57:58.360 --> 58:04.300 Up to now that shape of more children down here--stays 58:04.300 --> 58:10.020 unchanged and just the whole population gets bigger, 58:10.016 --> 58:12.366 you've seen that. 58:12.369 --> 58:18.899 Now contrast that to East Asia, which in 1950 had what looked 58:18.898 --> 58:24.768 like Sub-Saharan Africa: many more children than people 58:24.773 --> 58:29.383 in working ages, and again very few real old 58:29.382 --> 58:29.902 folk. 58:29.900 --> 58:34.750 Then time goes on but then you start seeing funny things happen 58:34.746 --> 58:37.276 where-- anyway up there follow 58:37.275 --> 58:42.505 the--anywhere from 1975 and 2000 to the left and you see now the 58:42.507 --> 58:45.577 number of children starts dipping. 58:45.579 --> 58:52.069 Up at the top it dips a lot and the bulge of children becomes a 58:52.065 --> 58:56.585 bulge in the working ages, so you may have a lot of people 58:56.585 --> 58:59.795 in working ages, very few children, 58:59.804 --> 59:05.474 no oldsters yet, so you don't have anybody that 59:05.465 --> 59:07.775 you have to support. 59:07.780 --> 59:11.450 What happens is, you calculate this dependency 59:11.447 --> 59:13.957 ratio; this is the number of working 59:13.958 --> 59:17.678 age people to non-working age and look what happens in East 59:17.677 --> 59:18.187 Asia. 59:18.190 --> 59:23.550 Here's the fertility decline, as soon as ten years have 59:23.554 --> 59:27.834 passed boom, boom, boom the ratio gets to be 59:27.827 --> 59:29.217 wonderful. 59:29.219 --> 59:32.679 Again we are--at this level we're somewhere near the peak, 59:32.682 --> 59:36.452 the rest of this is guesswork off to the right of that line. 59:36.449 --> 59:40.339 The dependency ratio just gets better and better for East Asia 59:40.335 --> 59:44.155 and this has tremendous--this is what has tremendous economic 59:44.157 --> 59:45.237 consequences. 59:45.239 --> 59:49.629 Here is the difference in the economic growth per year 59:49.634 --> 59:54.694 over--now this is a 25 year time period we're not looking at a 59:54.693 --> 59:56.023 single year. 59:56.018 --> 1:00:00.488 It's tremendously bigger than a place like Africa which has not 1:00:00.489 --> 1:00:02.219 reduced its fertility. 1:00:02.219 --> 1:00:05.529 We say this is based a lot on savings and you'll have a 1:00:05.532 --> 1:00:09.152 reading about this that you won't like because it's somewhat 1:00:09.152 --> 1:00:14.072 complicated economics, but look at the savings rate in 1:00:14.065 --> 1:00:15.215 East Asia. 1:00:15.219 --> 1:00:18.949 It goes from 1955, way before any of this, 1:00:18.945 --> 1:00:23.485 14% to 35%, it goes up like a factor of 2.5% or 3%; 1:00:23.489 --> 1:00:25.489 tremendous saving. 1:00:25.489 --> 1:00:28.129 Investment then, since you're saving, 1:00:28.130 --> 1:00:32.090 you can have an incredible increase in investment which 1:00:32.094 --> 1:00:35.034 builds up your country economically. 1:00:35.030 --> 1:00:37.840 Now the catch in this, that savings equals investment, 1:00:37.840 --> 1:00:41.000 you can also borrow money from abroad and so that's what they 1:00:41.001 --> 1:00:42.901 call the current account balance, 1:00:42.900 --> 1:00:48.020 how much money you can attract from abroad to get developed. 1:00:48.018 --> 1:00:50.828 We, in the West, believe that it was Western 1:00:50.829 --> 1:00:54.559 capital that went into China, allowed them to build up and 1:00:54.556 --> 1:00:56.186 did wonderful things. 1:00:56.190 --> 1:00:59.340 But no, it was never huge, this was a 4.8-- 1:00:59.340 --> 1:01:03.560 less than 5% was the current--now that's a minus sign 1:01:03.559 --> 1:01:07.219 in front of it, that's what they're importing, 1:01:07.222 --> 1:01:11.192 but very rapidly by 1980 they start to be a net capital 1:01:11.188 --> 1:01:12.068 exporter. 1:01:12.070 --> 1:01:15.910 That these poor countries have an excess of capital and they 1:01:15.907 --> 1:01:19.247 now export to us, so the development of China in 1:01:19.246 --> 1:01:21.646 particular, East Asia in general, 1:01:21.650 --> 1:01:24.910 is not as you would think a result of West-- 1:01:24.909 --> 1:01:26.449 infusion of Western capital. 1:01:26.449 --> 1:01:29.549 I mean some of the early special cases Hong Kong and so 1:01:29.554 --> 1:01:32.854 forth clearly were, but the main part of China, 1:01:32.851 --> 1:01:36.911 they produced their own capital because the sequence of 1:01:36.914 --> 1:01:41.754 causality is fertility decline, you wait 15,20 years all those 1:01:41.750 --> 1:01:43.670 kids grow up, there's none behind them, 1:01:43.672 --> 1:01:45.492 they all become workers, you start--you don't have 1:01:45.487 --> 1:01:47.297 children to support, you start saving, 1:01:47.295 --> 1:01:50.135 those savings become investments and you become one 1:01:50.137 --> 1:01:53.657 of the economic miracles or one of the tigers of the world. 1:01:53.659 --> 1:01:59.009 Now until recently, this theory is about 10 or 15 1:01:59.010 --> 1:02:01.840 years old, we're gradually coming to 1:02:01.842 --> 1:02:04.222 understand this idea about the economics, 1:02:04.219 --> 1:02:06.479 and we start seeing something special about Asia. 1:02:06.480 --> 1:02:10.040 That, yes, this was important, but also the culture of Asia, 1:02:10.039 --> 1:02:20.319 the propensity to saving--the savings-- 1:02:20.320 --> 1:02:23.060 when China was poor the savings were not fabulous, 1:02:23.059 --> 1:02:25.699 they are fabulous now, but they weren't then, 1:02:25.699 --> 1:02:27.489 that's a result of being rich. 1:02:27.489 --> 1:02:31.039 It was thought there was something special about East 1:02:31.039 --> 1:02:33.619 Asia and China, in particular, 1:02:33.623 --> 1:02:37.883 something cultural, and that when you did the 1:02:37.876 --> 1:02:42.126 econometrics you had to have one set of-- 1:02:42.130 --> 1:02:45.150 you could use the same amount, you have one set of parameters 1:02:45.150 --> 1:02:47.870 for Asia and a completely different set for Africa, 1:02:47.869 --> 1:02:51.289 and another set for Europe when you don't consider the 1:02:51.289 --> 1:02:52.839 demographic situation. 1:02:52.840 --> 1:02:56.290 Once you put in the demographic situation we now know that the 1:02:56.291 --> 1:02:58.331 same model fits around the world, 1:02:58.329 --> 1:03:01.329 and it looks like that this dependency burden is the key 1:03:01.333 --> 1:03:01.773 thing. 1:03:01.768 --> 1:03:04.698 One of the things that first clued us into this was Ireland. 1:03:04.699 --> 1:03:08.739 Ireland, which is a totally different culture than China, 1:03:08.739 --> 1:03:11.889 had this--it was totally Catholic and they really 1:03:11.891 --> 1:03:15.241 believed that they used Catholicism as fighting-- 1:03:15.239 --> 1:03:18.219 as a mode of fighting the British and so they had a very 1:03:18.215 --> 1:03:21.405 high birth rate and they didn't have legal contraception. 1:03:21.409 --> 1:03:24.869 In 1980 the government legalized contraception. 1:03:24.869 --> 1:03:28.079 Here's the birth rate, just takes a drive and then 1:03:28.083 --> 1:03:30.843 after a little blip, continues downward. 1:03:30.840 --> 1:03:33.440 Again, it's the government action of legalizing 1:03:33.440 --> 1:03:36.100 contraception and the Irish birth rate drops. 1:03:36.099 --> 1:03:38.729 The death rate, again, is slowly going down and 1:03:38.726 --> 1:03:42.096 then sort of not really going anywhere in this period and so 1:03:42.097 --> 1:03:44.437 the population growth rate decreases. 1:03:44.440 --> 1:03:48.210 Again, this is the same thing, you get the same effect that 1:03:48.211 --> 1:03:50.881 Ireland's population looks like China, 1:03:50.880 --> 1:03:52.340 on a smaller scale, it's not anywhere near as big 1:03:52.344 --> 1:03:53.774 as China, but again, you have an 1:03:53.766 --> 1:03:55.586 underdeveloped country looking thing. 1:03:55.590 --> 1:03:59.160 There was a lot more children than middle--than workers or old 1:03:59.161 --> 1:04:02.791 people and then this continues going up until you start getting 1:04:02.793 --> 1:04:03.793 this decline. 1:04:03.789 --> 1:04:07.019 Now in this modern period currently there's a lot more 1:04:07.023 --> 1:04:10.563 workers than there are either children or old people so the 1:04:10.561 --> 1:04:12.881 dependency burden looks real good. 1:04:12.880 --> 1:04:16.180 This is the graph of that. 1:04:16.179 --> 1:04:19.439 The purple curve on the bottom is Sub-Saharan Africa which 1:04:19.438 --> 1:04:22.408 again up--just consider what's up to the line because 1:04:22.411 --> 1:04:24.301 everything else is guesswork. 1:04:24.300 --> 1:04:28.630 Look, here the black is East Asia and the green is Ireland, 1:04:28.626 --> 1:04:30.636 looks very, very similar. 1:04:30.639 --> 1:04:35.759 Guess what the result is, here's where they legalized 1:04:35.755 --> 1:04:39.985 birth control, boom the economic growth rate 1:04:39.985 --> 1:04:44.505 just booms right up ten or so years later. 1:04:44.510 --> 1:04:50.910 Now comparing--starting to compare this to India, 1:04:50.914 --> 1:04:55.724 here is China's growth per capita. 1:04:55.719 --> 1:05:00.159 In 1960, China was poorer than India by a good bit, 1:05:00.159 --> 1:05:02.449 this is per capita income, the red is China, 1:05:02.449 --> 1:05:04.639 the blue is India, 1960 they're poorer, 1:05:04.639 --> 1:05:06.569 1970 they're poorer, and 1980 they're poorer. 1:05:06.570 --> 1:05:09.560 Wan, Xi, Shao, the later, longer, 1:05:09.557 --> 1:05:15.347 fewer, the fertility drop is in this period and it starts going 1:05:15.349 --> 1:05:19.739 and then China takes off and exceeds India. 1:05:19.739 --> 1:05:23.329 It's not due to the communist government or a good government 1:05:23.331 --> 1:05:27.051 because the communist revolution is way out here and for a long 1:05:27.045 --> 1:05:29.975 time it was not doing any better than India, 1:05:29.980 --> 1:05:33.740 but the main event that happened then is the drop in 1:05:33.744 --> 1:05:34.634 fertility. 1:05:34.630 --> 1:05:38.120 This shows you the difference in China's fertility and India's 1:05:38.115 --> 1:05:41.505 fertility, but here's this Chinese drop 1:05:41.512 --> 1:05:46.632 starting in 1970s and India slowly catching up but it's 1:05:46.626 --> 1:05:49.276 taking its time about it. 1:05:49.280 --> 1:05:54.540 This is the dependency burden, here again, the ratio of 1:05:54.541 --> 1:05:59.221 workers to non-workers really improving in China, 1:05:59.219 --> 1:06:03.409 not going anywhere particular in India. 1:06:03.409 --> 1:06:07.019 \When you compare it to Sub-Saharan Africa--again so 1:06:07.018 --> 1:06:11.188 we're comparing different parts of the world to show you the 1:06:11.192 --> 1:06:12.822 story--is the same. 1:06:12.820 --> 1:06:16.180 This is the birth rate, the black, and the death rate 1:06:16.175 --> 1:06:18.625 so a huge and continuing population; 1:06:18.630 --> 1:06:24.410 growth rate again up to the line, this is guesswork out here 1:06:24.409 --> 1:06:27.799 and here is-- again you've seen this before, 1:06:27.804 --> 1:06:32.684 this is China's-- East Asia's dependent ratio 1:06:32.677 --> 1:06:35.567 workers to children. 1:06:35.570 --> 1:06:38.730 This is Africa, there is a huge difference 1:06:38.731 --> 1:06:39.581 going on. 1:06:39.579 --> 1:06:46.049 This is the situation--in Sub-Saharan Africa the working 1:06:46.050 --> 1:06:50.050 age population has gone up 2.6%. 1:06:50.050 --> 1:06:53.420 Even if you can keep all those people employed when the 1:06:53.422 --> 1:06:56.802 dependent population goes up 2.7% you're not making any 1:06:56.797 --> 1:06:57.607 progress. 1:06:57.610 --> 1:07:00.590 Whereas in East Asia, still a significant dependent 1:07:00.594 --> 1:07:02.574 population, they haven't stopped having 1:07:02.565 --> 1:07:05.325 children altogether, but the working age population 1:07:05.333 --> 1:07:09.023 is growing half again as fast as the dependent population, 1:07:09.018 --> 1:07:12.678 that difference is what one, makes you rich and two, 1:07:12.679 --> 1:07:17.049 makes you be rich enough to save and invest and develop your 1:07:17.048 --> 1:07:17.788 country. 1:07:17.789 --> 1:07:22.779 You've again seen this graph, the difference between East 1:07:22.784 --> 1:07:24.394 Asia and Africa. 1:07:24.389 --> 1:07:33.009 That is the main idea that I wanted to get for you. 1:07:33.010 --> 1:07:36.020 I have to--by the way on your schedule this lecture was 1:07:36.023 --> 1:07:38.203 supposed to be given by David Bloom, 1:07:38.199 --> 1:07:40.259 who's a professor at Harvard, and one of the guys who did a 1:07:40.262 --> 1:07:40.942 lot of this work. 1:07:40.940 --> 1:07:44.300 He wasn't able to come so I used this--he came in the last 1:07:44.300 --> 1:07:47.660 time I gave this class and I used a lot of the slides that 1:07:47.659 --> 1:07:49.369 are David Bloom's slides. 1:07:49.369 --> 1:07:56.039 He's responsible for a fair chunk of this work. 1:07:56.039 --> 1:08:05.299 The end of this story is that, again, 1:08:05.300 --> 1:08:08.800 we talked about when--a long time ago when I describe 1:08:08.804 --> 1:08:11.424 Algeria's-- how much Algeria has gotten 1:08:11.416 --> 1:08:15.336 their fertility down but their population is still growing and 1:08:15.338 --> 1:08:19.008 they haven't been able to take advantage of a reduction in 1:08:19.005 --> 1:08:19.965 fertility. 1:08:19.970 --> 1:08:23.490 The same thing happens with these dependency burden issues, 1:08:23.488 --> 1:08:27.408 because you first have a lot more children than workers, 1:08:27.408 --> 1:08:31.518 than you stop having children, and that bulge grows and you 1:08:31.516 --> 1:08:34.276 get a lot more workers than children. 1:08:34.279 --> 1:08:38.049 Then those workers start to age as the population decreases and 1:08:38.047 --> 1:08:40.497 levels out, so now you have the reverse 1:08:40.497 --> 1:08:43.987 situation of a small number of workers and a large number of 1:08:43.990 --> 1:08:44.820 old people. 1:08:44.819 --> 1:08:50.589 Always in dependency burden you should add and old people and as 1:08:50.586 --> 1:08:54.326 your fertility goes does, your number of children goes 1:08:54.327 --> 1:08:56.007 down, your number of oldsters goes up, 1:08:56.010 --> 1:09:00.380 so it's not as bad--it's not as extreme a change as possible. 1:09:00.380 --> 1:09:03.950 This would seem to be called--this is called the 1:09:03.952 --> 1:09:07.452 demographic dividend, or the demographic bonus, 1:09:07.448 --> 1:09:08.968 this phenomenon. 1:09:08.970 --> 1:09:13.170 There's a time period when you can make great economic progress 1:09:13.172 --> 1:09:17.242 and then your people get old and a lot of people believe that 1:09:17.239 --> 1:09:20.019 Japan is in that situation right now. 1:09:20.020 --> 1:09:23.780 They have a very low birth rate and the number of old people is 1:09:23.783 --> 1:09:25.793 rising, and whereas in the past, 1:09:25.789 --> 1:09:29.169 old people cost almost nothing because just a little bit of 1:09:29.173 --> 1:09:30.933 food, they didn't eat much, 1:09:30.930 --> 1:09:34.360 but now with medical costs, old people require lots of 1:09:34.364 --> 1:09:37.574 money and in the past children were expensive, 1:09:37.569 --> 1:09:40.289 old people were cheap, now its reversed. 1:09:40.288 --> 1:09:43.178 The things that children use, clothing comes from China, 1:09:43.177 --> 1:09:45.437 it's very cheap, food is comparatively cheap 1:09:45.436 --> 1:09:46.536 around the world. 1:09:46.538 --> 1:09:48.648 I mean forget the last half year or something. 1:09:48.649 --> 1:09:53.479 Children used to be cheap--children used to be 1:09:53.480 --> 1:09:56.190 expensive; they're now getting cheaper, 1:09:56.189 --> 1:09:58.169 old people are getting very expensive. 1:09:58.170 --> 1:10:02.290 Now the worry is that any country that goes through a slow 1:10:02.287 --> 1:10:06.547 demographic change and doesn't arrange its economics and its 1:10:06.551 --> 1:10:10.511 politics to employ the people, because it doesn't do you any 1:10:10.514 --> 1:10:13.234 good if you have a lot of workers if they don't have any 1:10:13.234 --> 1:10:13.634 jobs. 1:10:13.630 --> 1:10:15.710 Latin America, for instance, 1:10:15.712 --> 1:10:19.492 which is kind of an in between situation--was very 1:10:19.490 --> 1:10:21.800 protectionist, and nationalist, 1:10:21.804 --> 1:10:24.354 and I can tell you a story. 1:10:24.350 --> 1:10:27.490 Bolivia, next door to Peru, and had so much conflict with 1:10:27.493 --> 1:10:30.813 Peru that they didn't want to form a common market with Peru 1:10:30.805 --> 1:10:34.115 and they'd rather buy plastic buckets from Brooklyn and rice 1:10:34.118 --> 1:10:37.198 from China than they would to trade with their next door 1:10:37.204 --> 1:10:38.164 neighbor. 1:10:38.158 --> 1:10:41.488 The story is that the demographic situation seems to 1:10:41.490 --> 1:10:45.480 be one of the major initiators of these economic miracles that 1:10:45.475 --> 1:10:49.325 have been happening around the world but they can't do it by 1:10:49.328 --> 1:10:50.438 themselves. 1:10:50.439 --> 1:10:54.279 There has to be the economic and political substructure to 1:10:54.279 --> 1:10:56.929 employ these people, to set them to work, 1:10:56.926 --> 1:10:59.556 and then a country gets rich and when it gets-- 1:10:59.560 --> 1:11:02.260 once it gets rich it gets the capital that it can keep it 1:11:02.262 --> 1:11:02.652 going. 1:11:02.649 --> 1:11:05.179 That you now have enough money to invest and keep going even 1:11:05.175 --> 1:11:07.525 though you may have to spend a lot on the old folks, 1:11:07.529 --> 1:11:11.439 you may be rich enough to generate the excess wealth to do 1:11:11.439 --> 1:11:11.919 that. 1:11:11.920 --> 1:11:18.830 Next time we'll talk about economics and the family, 1:11:18.828 --> 1:11:22.638 this has been macro economics, how economics works on a whole 1:11:22.644 --> 1:11:25.524 region wide thing, but what its effect is on a 1:11:25.521 --> 1:11:25.981 family. 1:11:25.979 --> 1:11:31.999
