This paper studies the optimal non linear income tax of couples. We build a general unitary model of labor supply and allow multidimensional heterogeneity in a discrete type framework. We concentrate our analysis on the resulting intra-family labor allocation of labor supplies and show that this...

The motivation for this symposium was the view that the problems of taxation of the family are very important, indeed central, for income tax policy, but are relatively neglected in theoretical public economics. We hope that this collection will stimulate interest and further work in this area....
