现在的城市经济学越来越多的重视住房市场和劳动市场之间的关系，认为如果随着距离的增加而且工作搜寻强度是内生的，那么空间失配（国内貌似是这么翻译的）现象就会产生。结果就是为了更低的住房消费而长期处于失业状态，那么廉租房（公共房屋）是否会使失业者倾向于更久的失业呢？作者用了两个工具变量分别测试了法国廉租房市场，得出结论是：廉租房并没有让失业者失业的更久！
我想这篇文章对中国的廉租房建设能够起到一定的借鉴作用，里面也提到了一些法国廉租房建设的相关信息 例如法国超过5万人以上大城市 廉租房市场达22%！

该文如果运用中国的数据应该可以做出一些不错的文章。

In order to test for the effect of public housing occupancy on unemployment, we estimate
a simultaneous probit model of unemployment and public housing. On a first sample, we
instrument public housing with the gender composition of children. On a second sample,
the instrument is the share of public housing at the city level. We also perform a robustness
check that consists in measuring the correlation between unobservables that could explain
the effect of public housing on unemployment. As the corresponding level of correlation is
low, this check reinforces our result of no effect of public housing on unemployment.
