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

We prove the non-emptiness of the core of an NTU game satisfying a condition of payoff-dependent balancedness, based on transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff vectors satisfying this condition. The additional...

This paper investigates how time and uncertainty interweave. Specifically, it studies the appearance of symmetries and asymmetries - with respect to the direction in which time flows - in the set of equilibria of simple overlapping generations economies which are open-ended in both directions,...

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

In a market where firms with different characteristics decide upon both the level of emissions and their reports, we study the optimal audit policy for an enforcement agency whose objective is to minimize the level of emissions. We show that it is optimal to devote the resources primarily to the...

This paper studies the incentives of short-lived agents to acquire costly private information in the presence of public signals arising from market interaction. It characterizes the social learning process, that is the revelation of information by public signals, and the information...

The model we discuss in this note is a re-examination of the classical Bertrand model of imperfect competition. the main difference is that consumers are allowed to have some strategic behavior when deciding from which one of the two sellers to buy. We will approach the resolution of the...
