We consider collective choice problems where a set of agents have to choose an alternative from a finite set and agents may or may not become users of the chosen alternative. An allocation is a pair given by the chosen alternative and the set of its users. Agents have gregarious preferences over...

We study efficiency and fairness properties of the equal cost sharing with maximal participation (ECSMP) mechanism in the provision of a binary and excludable public good. According to the maximal welfare loss criterion, the ECSMP is optimal within the class of strategyproof, individually...

We present an electoral theory on the public provision of local public goods to an imperfectly informed electorate. We show that electoral incentives lead to greater spending if the electorate is not well informed. A more informed electorate induces candidates to target funds only to specific...

We consider the classic cake-division problem when the cake is a heterogeneous good represented by an interval in the real line. We provide a mechanism to implement, in an anonymous way, an envy-free and efficient allocation when agents have private information on their preferences. The...

The theoretical literature on the cumulative innovation process has emphasized the role of ex-ante licensing – namely, licensing agreements negotiated before the follow-on innovator has sunk its R&D investment – in mitigating the risk of hold-up of future innovations. In this paper, we...

We analyze centralized housing markets under the existence of feasibility constraints on the number of agents and objects involved in the exchanges. We focus on an incomplete information setting where only the information about how each agent ranks her endowment is private. We show that under...
