In the robust statistics literature, a wide variety of models have been developed to cope with outliers in a rather large number of scenarios. Nevertheless, a recurrent problem for the empirical implementation of these estimators is that optimization algorithms generally do not perform well when...

Recent evidence suggests that aid induces migration. However, total migration is quite general from a policy perspective since what explains the welfare consequences of migration is the extent of emigration selection. In this paper we ask whether skilled or unskilled migration is more sensitive...
