We explore mechanism design with outcome-based social preferences. Agents' social preferences and private payoffs are all subject to asymmetric information. We assume quasi-linear utility and independent types. We show how the asymmetry of information about agents' social preferences can be...

In this paper we fully characterize an individual's choice behaviour according to three different so-called external references. The first system which we describe axiomatically is standard utility maximization or preference optimization. The second approach characterizes the choice of the...

This paper reports on the results of a series of experimental laboratory elections. The novelty of the design allows me to study both coordination failures and coordination efficiency in a repeated-game, divided majority setting. I assess and compare the performance of three voting mechanisms,...

We study how an optimal income tax and an optimal public-goods provision rule respond to preference and productivity shocks. A conventional Mirrleesian treatment is shown to provoke manipulations of the policy mechanism by individuals with similar interests. We therefore extend the Mirrleesian...

We prove a general possibility result for collective decision problems where individual allocations are one-dimensional, preferences are single-peaked (strictly convex), and feasible allocation profiles cover a closed convex set. Special cases include the celebrated median voter theorem (Black...

For an incomplete-information model of public-good provision with interim participation constraints, we show that efficient outcomes can be approximated, with approximately full surplus extraction, when there are many agents and each agent is informationally small. The result holds even if...

This paper studies a model of mechanism design with transfers where agents' preferences need not be quasilinear. In such a model, (1) we characterize dominant strategy incentive compatible mechanisms using a monotonicity property; (2) we establish a revenue uniqueness result: for every dominant...
