This article studies the properties of optimal fiscal policy in a stochastic growth model when the government cannot commit itself beyond the next period's capital income tax rate. We find that the results contrast markedly with those under full commitment. First, capital income tax rates are...

In this paper we present solutions to the optimal taxation problem in Poland in the case of high income earners. We characterize the actual data provided by the Polish Tax Authority and show that it is thick-tailed in the upper end of the distribution. Specifically, we show that income...

We analyze optimal capital and labor taxes in a model where (i) the government makes noncontingent announcements about future policies and (ii) ex-post state-contingent deviations from these announcements are costly. With Full Commitment, optimal fiscal announcements are unbiased forecasts of...

What are the implications of imperfect competition in labor markets for optimal labor income taxes? I study this question in an Aiyagari (1994) incomplete-market economy with idiosyncratic risk, borrowing constraints, and the new feature that jobs are differentiated from workers' perspective and...

This paper studies the aggregate and distributional implications of Markov-perfect taxspending policy in a neoclassical growth model with capitalists and workers. Focusing on the long run, our main findings are: (i) it is optimal for a benevolent government, which cares equally about its...
