In this article we quantify the aggregate, distributional and welfare consequences of two revenue neutral flat-tax reforms using a model economy that replicates the U.S. distributions of earnings, income and wealth in very much detail. We find that the less progressive reform brings about a 2.4%...

This paper seeks to explain the significant variations in the social contract observed across nations. It shows how countries with similar technologies and preferences, as well as equally democratic political systems, can sustain very different average and marginal tax rates. Similarly, it...

This paper studies the effects of progressive income taxes and education finance in a dynamic heterogeneous agent economy. Such redistributive policies entail distortions to labour supply and savings, but also serve as partial substitutes for missing credit and insurance markets. The resulting...

Even relatively poor people oppose high rates of redistribution because of the anticipation that they, or their children, may move up the income ladder. This ‘Prospect of Upward Mobility’ (POUM) hypothesis is commonly advanced to explain why democracies do not engage in large-scale...

Unilateral second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. Acceleration of global warming resulting from a future carbon tax is large if the price elasticities of oil demand are large and that of oil supply is...

This Paper explores the optimal role of the tax system in alleviating labour-market imperfections and raising revenue. For this purpose, the standard search model of the labour market is extended by introducing scarce entrepreneurial talent and arbitrage between the supply and demand. We study...

The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on unemployment; and the political difficulties in implementing more extensive reform programmes. We argue that the heart of...
