We study a large economy model in which individuals have private information about their productive abilities and their preferences for public goods. A mechanism design approach is used to characterize implementable tax and expenditure policies. A robustness requirement in the sense of Bergemann and Morris (2005) yields individual incentive compatibility constraints that are equivalent to those...

The consumer response to changing gasoline prices has long interested economists and policymakers, for it has important implications for the effects of gasoline taxation and vehicle energy efficiency policies. This study examines both the elasticity of driving with respect to changing gasoline prices and heterogeneity in this elasticity by geography, the fuel economy of the vehicle, and the age...

In this paper, I discuss the reasons for Costa Rica’s economic performance over the last quarter of a century. Three complementary sets of policies (investments in human capital, careful stabilization, and an intelligent and aggressive integration into the world economy) explain the successful trends, and can be thought of—at least in hindsight—as a development strategy. While fruitful, this st...

In the 1970s, taxation of "windfall" profits from primary products and intervention in trade and production tempted governments into expansionary fiscal policies, whilst stifling the private sector and depressing growth. However, the experience of the recent coffee boom has so far been more favourable: those African countries which liberalized and left a large share of the “windfall” with the p...

Why do so many African governments consistently impose high tax rates and make little investment in productive public goods, when alternative policies could yield greater tax revenues and higher national income? We posit and test an intertemporal political economy model in which the government sets tax and R&D levels while investors respond with production. Equilibrium policy and growth rates d...

This paper analyzes the effects of time-consistent capital taxation on the level of capital and welfare. We find that a commitment to a zero capital tax shifts the time inconsistency problem towards labor taxes and the provision of public consumption. By comparing the worst timeconsistent policies with and without a commitment to zero capital taxes, we find that the mere existence of a capital ...

Optimal Income Taxation of Married Couples: An Empirical Analysis of Joint and Individual Taxation In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this we...

We examine the allocation of hours of work across industrial sectors in OECD countries. We find large disparities across three sector groups, one that produces goods without home substitutes,and two others that have home substitutes but treated differently by welfare policy. We attribute the disparities to the countries’ tax and subsidy policies. High taxation substantially reduces hours in sec...
