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...

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 market in which k identical and indivisible objects are allocated using a uniform-price auction where n k bidders each demand one object. Before the auction, each bidder receives an informative but imperfect signal about the state of the world. The good that is auctioned is a...

In an economic theory of voting, voters have positive or negative costs of voting in favor of a proposal and positive or negative benefits from an accepted proposal. When votes have equal weight then simultaneous voting mostly has a unique pure strategy Nash equilibrium which is independent of...

We study the optimal design of student financial aid as a function of parental income. We derive optimal financial aid formulas in a general model. For a simple model version, we derive mild conditions on primitives under which poorer students receive more aid even without distributional...

This paper shows that agent inattention to taxes generates a time-inconsistency problem in the choice of tax policy. In equilibrium, inattention leads to inefficiently high tax rates and a taxation bias emerges. Combining structural and sufficient statistics approaches, we quantify the magnitude...

What are the implications of (endogenous) directed technical change for the design of redistributive income taxes? I study this question in a Mirrleesian economy augmented to include endogenous technology development and adoption choices by firms. Under certain conditions, any progressive tax...

This paper takes a mechanism design approach to federalism and assumes that local preferences are the private information of local jurisdictions. Contractual federalism is defined as a strategy-proof contract among the members of the federation supervised by a benevolent but not omniscient...

We study a model of public decision-making in simple public goods economies with moral hazards and adverse selection. Economic agents must invest resources (or provide effort) to discover their own preferences. We consider direct revelation mechanisms based on sampling. A sample of agents is...

We study contracting between a public good provider and users with private valuations of the good. We show that, once the provider extracts the users' private information, she benefits from manipulating the collective information received from all users when communicating with them. We derive...
