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...

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...

An important question in public economics is whether, and under what conditions, it may be possible to design a self-financing tax cut. This column provides new theoretical insights on the requirements for a tax reform that makes everyone better off. Furthermore, it shows that if there is no...

This paper studies the tax treatment of couples. We develop two different ap-proaches. One is tailored to the analysis of tax systems that stick to the principle that the tax base for couples is the sum of their incomes. One is tailored to the analysis of reforms toward individual taxation. We...

Are reforms towards individual taxation politically feasible? Are they desirable from a welfare perspective? We develop a method to answer such questions and apply it to the US federal income tax since the 1960s. Main findings are: As of today, Pareto-improvements require a move away from joint...

We study a large economy model in which individuals have private information about their productive abilities and their preferences. Moreover, there is aggregate uncertainty so that the social benefits from taxation and public goods provision are a priori unknown. The analysis is based on a...

We study the classical free-rider problem in public goods provision in a large economy with uncertainty about the average valuation of the public good. Individual preferences over public goods are shaped by a skill and a taste parameter. We use a mechanism design approach to solve for the...
