This Paper analyses strategic bargaining between two agents each of whom negotiates on behalf of a principal. The principals face uncertainty about the bargaining skills of their agents as measured by the agents' abilities to assess the opponent's preferences. Agents then have an incentive to...

Optimal voting rules have to be adjusted to the underlying distribution of preferences. However, in practice there usually is no social planner who can perform this task. This paper shows that the introduction of a stage at which agents may themselves choose voting rules according to which they...

In this paper we provide a characterization of the welfare properties of rational expectations equilibria of economies in which, prior to trading, agents have some information over the realization of uncertainty. We study a model with asymmetrically informed agents, treating symmetric...

I present a simple model in which it is possible that opening a new market makes everybody worse off. Unlike previous examples in the literature, the analysis does not rely on relative price changes of different consumption goods. This is shown in a standard framework in which uninformed traders...

Recent empirical work finds that surprisingly little variation in the demand for insurance is explained by heterogeneity in risks. I distinguish between heterogeneity in risk preferences and risk perceptions underlying the unexplained variation. Heterogeneous risk perceptions induce a systematic...

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...
