Dear Professor King, I am a Phd student of Economics at Universidad Carlos III, Spain. I was wondering if you could tell me: 1.Why you (and your coauthors) decided not to include marginal effects as a quantity of interest in the software of Relogit, nor mentioning them in your related papers. As you know, it’s probably the most used quantity of interest in Economics; in fact, I’ve found a number of papers that, in order to circumvent that “problem” of Relogit, they first estimate the regressions via both an ordinary logit and a relogit, compare the coefficients of the two regressions and argue that, since they don’t differ “substantially”, they stick to the ordinary logit because it allows the computation of marginal effects. 2.To the question of another student “How to get the marginal effects after running Relogit?” you answered “better than marginal effects are first differences, which are exact.” Although I have thoroughly read the 2 papers you wrote with L.Zeng in 2001 about Relogit, I don’t mananage to understand your answer. I would greatly appreciate your help regarding these issues.
