One element of this is the lack of representative surveys of immigrants.
Last week I posted about a nice experiment that Lori Beaman and Jeremy Magruder had done to understand the role networks play in job-referrals.
When done well, randomized experiments at least provide internal validity – they tell us the average impact of a particular intervention in a particular location with a particular sample at a particular point in time.
