This paper defines a general equilibrium model with exchange and club formation. Agents trade multiple private goods widely in the market, can belong to several clubs, and care about the characteristics of the other members of their clubs. The space of agents is a continuum, but clubs are...

This paper provides conditions on the primitives of a continuous-time economy under which there exist equilibria obeying the consumption-based capital asset pricing model. The paper also extends the equilibrium characterization of interest rates of Cox, Ingersoll, and Ross (1985) to multiagent...

We consider economies with incomplete markets, one good per state, two periods, t = 0; 1, private ownership of initial endowments, a single firm, and no assets other than shares in this firm. In Dierker, Dierker, Grodal (2002), we give an example of such an economy in which all market equilibria...

In this paper we analyze the welfare properties of the set of Drèze equilibria for economies with incomplete markets and firms. The well known fact that a Drèze equilibrium need not be constrained Pareto optimal is often attributed to a lack of coordination between firms. We show that there...
