<Para ID="Par1">We consider a model in which each agent in a population chooses one of two options. Each agent does not know what the available options are and can choose an option only after observing another agent who has already chosen that option. In addition, the agents’ preferences over the two options...</para>

We study a market with pair wise meetings of agents and with a one sided information asymmetry regarding the state of the world, which may be "low" or "high." We characterize the set of equilibria of the model, and study its behavior as the market becomes approximately friction less. For any one...

We study the welfare properties of a market with pairwise meetings and asymmetric information, establishing an equivalence between asymptotically expost individually rational and asymptotically (ex-ante, interim and ex-post) efficient equilibrium sequences. <!--ID="" Correspondence to:O. Yosha-->

We study a Gale-like matching model in a large exchange economy, in which trade takes place through non-cooperative bargaining in coalitions of finite size. Under essentially the same conditions of core equivalence, we show that the strategic equilibrium outcomes of our model coincide with the...
