The efficient side of progressive income taxation

This paper examines allocative properties of progressive income taxation when individuals care about their relative income. It shows that introducing a progressive income tax can yield a Pareto improvement if pre-tax income is evenly distributed. Implementing undistorted choices of working hours requires a progressive tax schedule, and the optimal degree of progressivity decreases with pre-tax income inequality. (C) 2002 Elsevier Science B.V.
