Abstract

In a second best environment, the optimal policy choice sometimes follows first best rules, as described in a number of scattered works. This paper presents a formal general argument which allows to unify much of the literature. It lays down the information structure and separability assumptions under which the results hold in a variety of setups, with extensions to preference heterogeneity and individual production sets
