We examine how three sources of asymmetric information affect the supply of entrepreneurs and unemployment. In the first case, banks cannot observe entrepreneurs' risk of failure so ration credit. This increases the number of entrepreneurs and the level of unemployment. In the second case, firms...

This paper surveys the evolution of the use of the theory of second best in public economics. It argues that much of modern normative public economics can be interpreted as simply applied second-best analysis. The original theory of second best as expounded by Lipsey and Lancaster involved...

The use of unemployment insurance and minimum wages as instruments for redistributing income are analyzed. The government is assumed to be able to implement an optimal income tax in an economy consisting of two ability-types of persons. The effect of introducing a minimum wage which induces...

The Atkinson-Stiglitz Theorem states that if labor is weakly separable from goods in household utility functions, differential commodity taxation should not be not part of an optimal redistributive tax system. This Theorem, which is arguable the most policy-relevant result to come out of the...

A model is constructed in which, given the inability of implicit contracts to be self-enforcing, a minimum wage policy combined with unemployment insurance can be welfare-improving. Unemployment insurance can be decentralized to the private sector if the government can commit to a minimum wage....
