It is well known that ex post efficient mechanisms for the provision of indivisible public goods are not interim individually rational. However, the corresponding literature assumes that agents who veto a mechanism can enforce a situation in which the public good is never provided. This paper...

This paper considers the canonical sequential screening model and shows that when the agent has an ex post outside option, the principal does not benefit from eliciting the agent's information sequentially. Unlike in the standard model without ex post outside options, the optimal contract is...

This paper studies equilibria for economies characterized by moral hazard (hidden action), in which the set of contracts marketed in equilibrium is determined by the interaction of financial intermediaries. The crucial aspect of the environment that we study is that intermediaries are restricted...

A 'folk theorem' originating, among others, in the work of Stiglitz maintains that competitive equilibria are always or 'generically' inefficient (unless contracts directly specify consumption levels as in Prescott and Townsend, thus bypassing trading in anonymous markets). This paper critically...

We build a theory of prosocial behaviour that combines heterogeneity in individual altruism and greed with concerns for social reputation or self-respect. The presence of rewards or punishments creates doubt as to the true motive for which good deeds are performed, and this ‘overjustification...

We consider a model of education planning in an economy in which agents differ in their costs of acquiring education. The agents' cost parameter, called "talent," is not observed. The Principal is endowed with a fixed sum of money, with which two types of transfer can be made: in cash and in...

We re-address the tradeoff between centralized and decentralized decision making of local policies when policymakers are subject to capture by special interest groups. In particular, we consider the case where lobbies have private information about their ability to exert influence. We find a new...

A risk averse agent gathers information on productivity shocks and produces accordingly on behalf of his principal. Information gathering is imperfect so that the agent has either complete or no knowledge at all of those shocks. The model allows for moral hazard in information gathering, private...

In a Hotelling duopoly model, we introduce quality that is more appreciated by closer consumers. Then higher common quality raises equilibrium prices, in contrast to the standard neutrality result. Furthermore, we allow consumers to buy one out of two goods (single-purchase) or both...

We develop a simple theory which formally describes how charities can resolve the information asymmetry problems faced by small donors by working with large donors to generate quality signals. To test the model, we conducted two large-scale natural field experiments. In the first experiment, a...
