00:00:03.630 --> 00:00:05.630
欢迎来到诺贝尔谈话

00:00:06.930 --> 00:00:10.300
本集中 Josh Angrist 
和 Guido Imbens

00:00:10.300 --> 00:00:13.380
将会和 Isaiah Andrews 
一同探讨

00:00:13.380 --> 00:00:16.700
他们获得诺贝尔奖的合作中的一些关键部分

00:00:16.700 --> 00:00:19.590
Josh，Guido，首先恭喜你们
获得了诺贝尔奖！

00:00:19.590 --> 00:00:20.620
谢谢

00:00:20.620 --> 00:00:23.190
- [Isaiah] 你们一起完成的工作

00:00:23.190 --> 00:00:24.778
特别是在局部平均处理效应

00:00:24.778 --> 00:00:25.986
或 LATE 框架

00:00:25.986 --> 00:00:28.900
据说是获奖的重要原因之一

00:00:29.200 --> 00:00:32.600
而且，你们在哈佛重合的时间只有一年

00:00:32.900 --> 00:00:34.300
如果我没记错的话——

00:00:35.210 --> 00:00:36.650
跟我们分享一下

00:00:36.650 --> 00:00:38.500
你们是如何开始合作的

00:00:38.500 --> 00:00:40.964
以及是什么让你们的工作关系富有成效

00:00:40.964 --> 00:00:43.600
有没有什么方式让你觉得可以互相称赞

00:00:43.600 --> 00:00:46.470
是什么让事情变得这么有成效？

00:00:46.790 --> 00:00:50.624
我记得你的工作，Guido，没那么有意思

00:00:50.624 --> 00:00:52.740
但我觉得这是一个基于选择的样本

00:00:52.740 --> 00:00:54.600
是的，是的

00:00:54.600 --> 00:00:56.280
我其实是一个非常边缘化的雇员

00:00:56.280 --> 00:00:58.336
因为他们根本没按正常的招聘市场那样面试我

00:00:58.336 --> 00:00:59.830
。

00:00:59.830 --> 00:01:03.000
但我觉得他们非常急切的需要一个人

00:01:03.000 --> 00:01:04.900
来教授这些课程

00:01:05.920 --> 00:01:08.470
其实已经过去好几个研讨会了

00:01:08.470 --> 00:01:11.123
但他们还想找人来教计量经济学

00:01:11.135 --> 00:01:13.940
- 所以 Gary 给我打电话
- [Josh] Gary Chamberlain?

00:01:13.940 --> 00:01:16.700
Gary Chamberlain 打给我
然后电话面试了我

00:01:17.400 --> 00:01:19.474
他说：“要不你来一趟

00:01:19.474 --> 00:01:20.828
我们谈谈？”

00:01:21.089 --> 00:01:23.411
- [Josh] 我有点印象

00:01:23.411 --> 00:01:26.941
我记得我们和 Gary 一起吃了个晚饭

00:01:29.000 --> 00:01:32.900
我记得我对你的工作经验不是非常满意

00:01:33.600 --> 00:01:38.220
但幸运的是，Gary 的观点占了上风

00:01:38.580 --> 00:01:39.600
没错

00:01:39.600 --> 00:01:41.900
- [Josh] 然后哈佛给了你录取通知

00:01:42.400 --> 00:01:46.056
然后从你1990年秋天来了以后

00:01:46.056 --> 00:01:49.810
我记得我们就经常在一起讲话了，对吧？

00:01:49.810 --> 00:01:52.990
就像我说的，我来了以后
没有一个清楚的日常安排

00:01:52.990 --> 00:01:55.700
来了以后我有点被吓到

00:01:56.000 --> 00:01:59.776
但是 Gary 说 “不
你应该和 Josh 谈谈”

00:01:59.776 --> 00:02:04.578
你应该去参加劳工研讨会
看看这些人是怎么做的

00:02:04.578 --> 00:02:06.990
他们做的事挺有意思的

00:02:07.470 --> 00:02:08.880
我听了 Gary 的

00:02:09.880 --> 00:02:10.938
就像我们一样

00:02:10.938 --> 00:02:14.834
就像我们当年以及之后所做的

00:02:14.834 --> 00:02:16.700
我觉得我们是邻居这点帮了不少忙

00:02:16.700 --> 00:02:20.774
我们都住在哈佛的初级教师宿舍

00:02:22.030 --> 00:02:25.040
部分原因是因为相比我们非常低的薪水来说

00:02:25.040 --> 00:02:27.200
剑桥的住宿费太高了

00:02:27.800 --> 00:02:29.456
我觉得我们都不是来自剑桥这一点

00:02:29.456 --> 00:02:31.212
也帮了不少忙

00:02:31.212 --> 00:02:33.360
那里有很多麻省理工的人

00:02:33.360 --> 00:02:36.027
他们已经有自己的社交圈了

00:02:36.441 --> 00:02:37.800
就像我们的合作者一样

00:02:37.800 --> 00:02:39.460
♪ [音乐] ♪

00:02:39.460 --> 00:02:41.850
- [Josh] 我觉得我们琢磨出

00:02:41.850 --> 00:02:43.800
一套适合我们的工作方式

00:02:43.800 --> 00:02:46.410
我们过的非常规律，所以才能是邻居

00:02:46.860 --> 00:02:48.760
我们经常一起洗衣服

00:02:49.510 --> 00:02:51.912
在我们的公寓里没有洗衣机

00:02:52.500 --> 00:02:55.450
但我们过去经常洗衣服，经常一起聊天

00:02:55.450 --> 00:02:59.072
你有一种非常系统的方式

00:03:00.330 --> 00:03:03.300
来解决我们讨论中会出现的问题

00:03:03.300 --> 00:03:05.562
我印象深刻的一件事是

00:03:06.400 --> 00:03:08.728
我们早期的互动，你会持续跟进

00:03:09.993 --> 00:03:11.500
你会把事情记下来

00:03:11.500 --> 00:03:13.250
回想那段时间，还是挺记忆犹新的

00:03:13.250 --> 00:03:16.460
我有大量的时间去思考

00:03:16.460 --> 00:03:17.915
我现在看到我初级的同事们

00:03:17.915 --> 00:03:19.580
[Guido] 你现在没空思考了

00:03:19.580 --> 00:03:22.753
[Josh] 没有，但是对我来说，这是一回事

00:03:22.753 --> 00:03:24.850
我现在觉得很多初级同事

00:03:24.850 --> 00:03:27.200
没有足够多的时间思考

00:03:27.200 --> 00:03:29.710
人们在做很多项目

00:03:29.710 --> 00:03:31.800
这些项目都很难

00:03:31.800 --> 00:03:34.560
人们出版的压力很大

00:03:34.560 --> 00:03:38.081
我记得我花很多时间坐在我的办公室里

00:03:38.081 --> 00:03:41.505
想着 “我现在应该干什么？”

00:03:41.505 --> 00:03:42.835
[笑声]

00:03:43.410 --> 00:03:45.096
我有很多时间

00:03:45.096 --> 00:03:46.883
去想这些问题

00:03:46.883 --> 00:03:48.790
然后尝试解决它们

00:03:48.790 --> 00:03:50.610
我可以去研讨会

00:03:52.000 --> 00:03:56.651
然后第二天和 Josh 或者 Gary 
一起喝咖啡或者吃午饭

00:03:56.651 --> 00:03:58.640
然后讨论事情

00:03:58.640 --> 00:04:00.169
- [Isaiah] 你们一起在哈佛的时间

00:04:00.169 --> 00:04:01.558
其实没有那么长

00:04:01.558 --> 00:04:03.300
你们很快就在一起工作了

00:04:03.300 --> 00:04:06.600
你们当时是否都在寻找共同作者的心态

00:04:06.600 --> 00:04:09.260
或者当时正在寻找特定类型的共同作者

00:04:09.260 --> 00:04:11.600
还是比这更偶然？

00:04:11.600 --> 00:04:13.020
- [Josh] 我觉得我们很幸运

00:04:13.020 --> 00:04:15.444
我不记得我在寻找什么

00:04:16.130 --> 00:04:17.900
我觉得这更多是偶然

00:04:18.370 --> 00:04:21.411
我说我进来了，我已经做完了我的就业市场论文

00:04:21.411 --> 00:04:23.110
以及另一篇论文

00:04:23.110 --> 00:04:25.500
我很高兴来到哈佛

00:04:25.500 --> 00:04:27.701
突然间有所有这些研讨会可以参加

00:04:28.262 --> 00:04:30.712
还有很多有趣的人可以交谈

00:04:31.200 --> 00:04:35.805
但这对我来说并不是一件非常有意识的事情

00:04:36.300 --> 00:04:39.200
回想起来，我想有一段时间

00:04:39.700 --> 00:04:42.933
我和 Guido 讨论了

00:04:42.933 --> 00:04:46.020
工具变量、潜在结果、治疗效果

00:04:47.000 --> 00:04:49.859
我们进行了很好的讨论

00:04:49.859 --> 00:04:54.539
之后他也给我发了一些笔记

00:04:55.770 --> 00:05:00.695
这些笔记非常有条理的记录了我们的讨论

00:05:00.695 --> 00:05:02.966
和您的想法

00:05:03.600 --> 00:05:07.457
我们以一种相当正式的方式得出结论

00:05:07.457 --> 00:05:09.887
我想，“嗯，那太好了。”

00:05:10.340 --> 00:05:13.020
光说没用，对吧，但是和...

00:05:13.020 --> 00:05:15.514
- [Guido] 对，但是
- 书写了他们的故事

00:05:15.900 --> 00:05:18.500
- [Guido] 对我来说，把事情写下来更好

00:05:18.500 --> 00:05:22.771
我记得和 Josh 一起工作

00:05:22.771 --> 00:05:26.163
坐在我的办公室里，把事情写下来

00:05:26.633 --> 00:05:28.880
你们都和 Gary 说过话

00:05:28.880 --> 00:05:32.212
之后我们需要坐下来

00:05:32.212 --> 00:05:33.920
真正写下事情

00:05:33.920 --> 00:05:36.641
以弄清楚到底发生了什么

00:05:37.810 --> 00:05:39.360
我记得另一件我们一起做的事情，Guido

00:05:39.360 --> 00:05:40.507
我们从应用当中

00:05:40.507 --> 00:05:41.655
得出来很多非常具体的问题

00:05:41.655 --> 00:05:43.610
- [Guido] 对

00:05:43.610 --> 00:05:45.000


00:05:45.600 --> 00:05:47.465


00:05:47.870 --> 00:05:51.421


00:05:51.421 --> 00:05:55.411


00:05:57.110 --> 00:06:00.200


00:06:00.500 --> 00:06:03.800


00:06:04.830 --> 00:06:06.300


00:06:06.300 --> 00:06:07.300


00:06:07.300 --> 00:06:11.930


00:06:11.930 --> 00:06:14.890


00:06:14.890 --> 00:06:16.970

00:06:24.410 --> 00:06:26.890


00:06:26.890 --> 00:06:28.170


00:06:28.170 --> 00:06:30.900


00:06:30.900 --> 00:06:32.100

00:06:40.400 --> 00:06:42.738


00:06:42.738 --> 00:06:46.500


00:06:46.500 --> 00:06:48.805


00:06:49.390 --> 00:06:51.774


00:06:53.800 --> 00:06:57.724


00:06:58.120 --> 00:07:00.985


00:07:03.200 --> 00:07:05.050


00:07:05.050 --> 00:07:06.900


00:07:09.370 --> 00:07:11.754
