This paper analyzes taxes and transfers in an economy with three distinct levels of government. It is assumed that the different levels of government raise revenue through distortionary income taxation, resulting in vertical fiscal externalities. We show how to implement a socially optimal...

This paper concerns optimal taxation and provision of a public good in the context of the mixed tax problem, where the set of tax instruments consists of a nonlinear income tax and linear commodity taxes. The analysis is based on a two-type model with endogenous wage rates. Contrary to previous...

This paper deals with public provision of a private good in a two-type model with optimal nonlinear income taxation. We assume that the wage rates are determined by bargaining between unions and firms, meaning that the equilibrium is characterized by unemployment. The results show that imperfect...

This paper concerns the welfare consequences of environmental policy cooperation in a two-country economy. We assume that the countries finance their public expenditures by using distortionary taxes, and that they differ with respect to competition in the labor market. The purpose is to...

This paper deals with optimal income and commodity taxation in an economy, where alcohol is an externality-generating consumption good.

This paper analyzes the welfare effects of a publicly provided private good with long-term consequences for individual well-being, in an economy where consumers have present-biased preferences due to quasihyperbolic discounting. The analysis is based on a two-type model with asymmetric...
