Female Labor Supply with Taxation, Random Preferences, and Optimization Errors

Abstract

This paper develops a model of labor supply for married women which takes into account both the joint decision on participation and hours, and the nonlinear shape of the budget constraint due to taxation. The model can explain the absence of observations of the tax kink by assuming the existence of optimization errors in addition to errors capturing taste variation. The estimates of the model, which are obtained with British micro data, suggest that the overall wage elasticity is about 2 and that participation is more responsive to wages than hours of work.
