We implement the core correspondence in Subgame Perfect Equilibrium using a simplesequential mechanism in which firms propose a salary to each worker (in the first stage). Then ,each worker accepts at most one proposal (second stage). Moreover, we show that, if agents'preferences are additive,...

This paper analyzes the problem of designing mechanisms to implement efficient solutions in economies with externalities. We provide two simple mechanisms implementing the Pigouvian Social Choice Correspondence in environments in which coalitions can be formed. Finally, we study economies in...

This paper provides three simple mechanisms to implement allocations in the core of matching markets. We analyze some sequential mechanisms which mimic matching procedures for many-to-one real life matching markets. We show that only core allocations should be attained when agents act...

We characterize the incentive compatible allocation that maximizes the expected social surplus in a single-unit sale when the efficient allocation is not implementable. This allocation may involve no selling when it is efficient to sell. We then show that the English auction always implements...

Let µ be a rational distribution over a finite alphabet, and ( ) be a n-periodic sequences which first n elements are drawn i.i.d. according to µ. We consider automata of bounded size that input and output at stage t. We prove the existence of a constant C such that, whenever , with...

This paper presents a model of network formation with costly links. We endogenize the amount of cost born by each player involved in a bilateral link by considering that these shares result from bargaining. We analyze this feature in a context of coordination games. We show that, if the cost of...

This paper presents a model in which players interact via the formation of costly links and the benefits of bilateral interactions are determined by a coordination game. A novel contribution of this paper is that the fraction of the cost borne by each player involved in a bilateral link is not...

This paper studies simple hiring procedures for job markets. We show that when agents act strategically only individually rational outcomes should be expected. Moreover, If agents can form unions, thereby gaining the possibility to commit on the decision to be chosen, only stable allocations are...
