Tax competition between two governments who choose nonlinear income tax schedules to maximize the average utility of its residents when skills are unobservable and labor is perfectly mobile is examined. We show that there are no Nash equilibria in which there is a skill type that pays positive...

The literature on public goods has shown that efficient outcomes are impossible if participation constraints have to be respected. This paper addresses the question whether they should be imposed. It asks under what conditions efficiency considerations justify that individuals are forced to pay...

A uniform price for carbon is at the center of market-based approaches to climate policy. Actual climate policy, by contrast, has many sector-specific rules. This paper studies the desirability of the market-based approach using tools from the theory of taxation. It is found that a justification...

This paper provides necessary and sufficient conditions for the existence of Pareto-improving tax reforms. The conditions can be expressed as sufficient statistics and have a wide range of potential applications in public finance. We discuss one such application in detail: the introduction of...

We study reforms of non-linear income tax systems from a political economy perspective. We present a median voter theorem for monotonic tax reforms, reforms so that the change in the tax burden is a monotonic function of income. We also provide an empirical analysis of tax reforms, with a focus...

This paper provides necessary and sufficient conditions for the existence of Pareto-improving tax reforms. The conditions can be expressed as sufficient statistics and have a wide range of potential applications in public finance. We discuss one such application in detail: the introduction of...

Gerrymandering undermines representative democracy by creating many uncompetitive legislative districts, and generating the very real possibility that a party that wins a clear majority of the popular vote does not win a majority of districts. We present a new approach to the determination of...

This article discusses whether supply chain due diligence laws are a suitable instrument for goals of sustainability. It uses the German due diligence law as an example and makes recommendations for the design of European rules. The emerging evidence on the effect of trade policies in global...

We develop a model of political competition with endogenous turnout and endogenous platforms. Parties trade off incentivizing their supporters to vote and discouraging the supporters of the competing party from voting. We show that the latter objective is particularly pronounced for a party with...

The design of redistributive tax policies is an evergreen in the public discourse. This column proposes a new approach for the political economy analysis of tax policies based on examining the political support for reforms in contrast to the tax systems themselves. Focusing on monotonic tax...
