In this note we extend Jackson and WattsJET2002''s result on the coincidence of S-stochastically stable and core stable networks from the marriage problem to the solvable roommate problem. In particular, we show that the polarization structure of the marriage problem on which the proof of...

We consider multiple-type housing markets. To capture the dynamic aspect of trade in such markets, we study a dynamic recontracting process similar to the one introduced by Serrano and Volij (2005). First, we analyze the set of recurrent classes of this process as a (non-empty) solution concept....

This paper reports on a laboratory experiment which investigates the impact of institutions and institutional choice in constant-sum sender-receiver games. We compare individual sender and receiver behavior in two different institutions: A sanction-free institution which is given by the bare...

Real-world contests are often "unfair" in the sense that outperforming all rivals may not be enough to be the winner, because some contestants are favored by the allocation rule, while others are handicapped. Examples of such contests can be inter alia found in the area of litigation and...

We show in a sender-receiver game with strictly opposing interests that rewards enhance trust but do not influence truth-telling. Subjects who reward tend to tell the truth and trust more often in the presence and absence of reward opportunities. The amount of obtained rewards thereby enhances...

We consider several notions of setwise stability for many-to-many matching markets with contracts and provide an analysis of the relations between the resulting stable sets and pairwise stable sets for general, substitutable, and strongly substitutable preferences. Apart from obtaining “set...

We show that for any roommate market the set of stochastically stable matchings coincideswith the set of absorbing matchings. This implies that whenever the core is non-empty (e.g.,for marriage markets), a matching is in the core if and only if it is stochastically stable, i.e., stochastic...

We consider optimal contracts when a principal has two sources to detect bad projects. The first one is an information technology without agency costs ($%IT_{P}$), whereas the second one is the expertise of an agent subject to moral hazard, adverse selection and limited liability ($IT_A$)....
