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...

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...

This paper studies a large majority election with voters who have heterogeneous, private preferences and exogenous private signals. We show that a Bayesian persuader can implement any state-contingent outcome in some equilibrium by providing additional information. In this setting, without the...

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...

In many organizations, members need to be assigned to certain positions, whether these are legislators to committees, executives to roles, or workers to teams. I show that these assignment problems lead to novel questions about institutional stability. Will the set of agents being assigned...

This paper provides empirical evidence on the aggregation of information in committees. We analyze unique data from the decision-making process of hiring committees within a large private company. In the hiring process, committee members first conduct independent one-to-one interviews and give...

In today's highly complex economic environment, cooperation among individuals is crucial for organizational and societal success. Most of the situations in which cooperation is required involve costly efforts whose consequences play out over time. Here, we provide a systematic and comprehensive...

Understanding the roots of human cooperation among strangers is of great importance for solving pressing social dilemmas and maintening public goods in human societies. We study the development of cooperation in 929 young children, aged 3 to 6. In a unified experimental framework, we examine...
