      abstract = {This article describes the user-written program margeff,  which enables the fast estimation of (average) marginal  effects. Besides describing the program, this article  offers a new discussion of some problems that are related  to computation of marginal effects. I will argue that (1)  marginal effects computed at means are not good  approximations of average marginal effects, computed as  means of marginal effects evaluated at each observations,  if some of the parameter estimates are large; (2) both  average marginal effects and marginal effects computed at  means might produce wrong estimates for dummies that are  part of a set of indicator variables indicating different  categories of a single underlying variable; and (3) the use  of marginal effects computed at means is preferred if some  of the regressors are mathematical transformations of other  regressors.},
