We propose a simple mechanism that implements the Ordinal Shapley Value (Prez-Castrillo and Wettstein [2005]) for economies with three or less agents.

We propose a new solution concept to address the problem of sharing a surplus among the agents generating it. The problem is formulated in the preferences-endowments space. The solution is defined recursively, incorporating notions of consistency and fairness and relying on properties satisfied...

We use experimental data to obtain a detailed description of individuals' pro-sociality. Participants are faced with a large number of decisions involving variations in the tradeoffs between own and others' payoffs, as well as in other potentially important factors like individuals' positions...

We study how the heterogeneity of agents affects the extent to which changes in financial incentives can pull a group out of a situation of coordination failure. We focus on the connections between cost asymmetries and leadership. Experimental subjects interact in groups of four in a series of...

We study random assignment economies with expected-utility agents, each of them eventually obtaining a single object. Inspired on Hylland and Zeckhauser’s (1979) Pseudomarket mechanism (PM) and on a serial dictatorship, we introduce the Sequential Pseudomarket (SP) where groups of agents...

We present a model in which an individual's sentiments toward others are determined endogenously on the basis of how they perform relative to the societal average. This, in turn, affects the individual's own behavior and hence other agent's sentiments toward her. We focus on stationary patterns...

We present a model in which each agent's sentiments toward others are determined endogenously on the basis of how they behave relative to a standard of appropriate behavior. As sentiments change, so too does the optimal behavior of each individual, which in turn affects other agents' sentiments...

While the theoretical industrial organization literature has long argued that excess capacity can be used to deter entry into markets, there is little empirical evidence that incumbent firms effectively behave in this way. Bagwell and Ramey (1996) propose a game with a specific sequence of moves...

I study large random assignment economies with a continuum of agents and a …finite number of object types. I consider the existence of weak priorities discriminating among agents with respect to their rights concerning the …final assignment. The respect for priorities ex ante (ex-ante...

We study how to promote compliance with rules in every day situations. Having access to unique data on the universe of users of all public libraries in Barcelona, we test the effect of sending email messages with different contents. We find that users return their items earlier if asked to do...
