In a 2015 ASR article, I introduced SISTER, a new method to estimate the causal effects of culture using migrant populations.  In a critical comment, Chou raises significant concerns about SISTER and concludes that the method is flawed. In a subsequent reply I contend that Chou’s conclusion is incorrect because it is based on a mischaracterization of the methods’ identification assumptions. Here you can download my original article, Chou's comment and my reply, together with supplementary material, including an annotated guide to implementation comands (in Stata).
