i've taken posner twice, and he is a very standard social science professor. pretty inaccessible and but gives very straightforward lectures, the readings are all case studies pertaining to the week's content. posner takes a pretty neoliberal stance in his approach to development and never really questions it, which I don't appreciate. exams are simple in my opinion, except the take home midterm which was a 6-8 page paper that we only had 48 hours to do!!! not a difficult class in general tho
