I provide a simple model that is solved analytically to yield tidy expressions for the Pareto efficient tax structures and the optimal two-bracket marginal tax rates. It is for the special case of equally-sized groups of two skill types and no exogenous spending requirements of the government....

The development of the welfare state in the Western economies between 1930 and 1990 coincided with a puzzling pattern in the taxation of top incomes. Effective tax rates at the top increased sharply but then gradually decreased, even as social transfers continued rising. We propose a new theory...

We construct the ratio of the post-fisc transitory income variance to the pre-fisc transitory income variance of family incomes as a measure of fiscal progressivity in Canada between 1993 and 2008. This ratio can be interpreted as measuring the extent to which the fiscal system attenuates...

We develop a simple model of interregional tax competition to explore how the balance between common and region-specific aspects of a project's value affects the magnitudes of tax breaks offered by governments, when the firm possesses private information on the region-specific values. We examine...
