EDIT: Faatima Osman questioned whether it was fair to exclude respondents from Benin, Ghana and Nigeria in Nunn and Wantchekon’s paper, given that Nigeria is the most populated country in Africa by far.
And in hindsight I think she is totally right—respondents from these countries are ~25% of the sample! I now believe that its unfair to call these respondents outliers. Correspondingly, my trust in Nunn and Wantchekon’s paper has gone up, since Kelly’s critique was my main concern about it.
