This paper estimates public sector wage differentials and their changes over time for men and women in the United Kingdom using panel data from the New Earnings Survey/Annual Survey of Hours and Earnings for the period 1975 to 2006.

This paper examines the optimal schedule of marginal tax rates and the design of earned income tax credits.

This paper surveys the potential benefits of integration and the potential obstacles.

This paper develops IV estimators for unconditional quantile treatment effects (QTE) when the treatment selection is endogenous.

We examine the impact of recent reforms on private pension coverage and on contributions to personal pension accounts.

Hedonic pricing with quasilinear preferences is shown to be equivalent to stable matching with transferable utilities and a participation constraint, and to an optimal transportation (Monge-Kantorovich) linear programming problem.
