In this paper, we study a two-country dynamic setup with environmental externalities and potential model mis-specification in relation to this public good. Under model uncertainty, robust policies help to correct the inefficiencies associated with free riding on public good provision, implying...

We provide a quantitative assessment of the welfare cost of tax competition or, equivalently, the welfare benefit of international tax policy cooperation. We use a simple multi-country general equilibrium model of a world economy, in which there are two types of cross-country spillovers: the...

This paper studies the difference between public production and public finance of public goods in a dynamic general equilibrium setup. By public finance, we mean that the public good is produced by private providers with the government financing their costs. When the model is calibrated to match...

This paper studies the aggregate and distributional implications of introducing user fees for publicly provided excludable public goods into a model with consumption and income taxes. The setup is a neoclassical growth model where agents differ in earnings and second-best policy is chosen by a...

We reconsider the conventional wisdom that, in the presence of public goods and distortionary taxation, Nash tax rates are inefficiently low due to free riding. We use a model in which the public good is natural resources. Specifically, a general equilibrium model of a world economy, in which...
