One of the comments we got last week was a desire to see more “behind-the-scenes” posts of the trials and tribulations of trying to run an impact evaluation. I am sure we will do more of these, but there are many times I have thought about doing so and baulked for one of the following reasons:
randomization in the wild
Despite the large and growing literatures on migration in economics, sociology, and other social sciences, there is surprisingly little work which actually evaluates the impact of particular migration policies (most of the literature concerns the determinants of migrating, and the consequences of doing so for the migrants, their families, and for native workers). I am therefore always interested to see new work in this area, particularly work which manages to obtain experimental variation in policy implementation.
