We propose a new approach to the normative analysis of public-good provision. In addition to individual incentive compatibility, we impose conditions of robust implementability and coalition proofness. Under these additional conditions, participants' contributions can only depend on the level of...

We study a dynamic model of team production with moral hazard. We show that the players begin to invest effort only shortly before the time limit when the reward for solving the task is shared equally. We explore how the team can design contracts to mitigate this form of procrastination and show...

A version of the Second Fundamental Theorem of Welfare Economics that applies to a money-free environment, in which a set of indivisible goods needs to be matched to some set of agents, is established. In such environments, 'trade' can be identified with the set of hierarchical exchange...

This paper shows how the optimal level of Pigouvian taxation is influenced by distributive concerns. With second-best instruments, a higher level of income redistribution calls for a lower level of Pigouvian taxation. More redistributionimplies that tax collection via the income tax creates...

A robust feature of models of electoral competition between two opportunistic, purely office-motivated parties is that both parties become indistinguishable in equilibrium. I this short note, I show that this strong connection between the office motivation of parties and their equilibrium choice...

We show that a steeply increasing workload before a deadline is compatible with time-consistent preferences. The key departure from the literature is that we consider a stochastic environment where success of effort is not guaranteed.

This article is concerned with the welfare properties of trade when the behavior of agents cannot be rationalized by preferences. I investigate this question in an environment of matching allocation problems. There are two reasons for doing so: firstly, the finiteness of such problems entails...
