We develop a model of general equilibrium with trade ex ante in a context of private and incomplete state verification. Instead of choosing bundles, agents choose lists of bundles out of which the market then selects one bundle for delivery. With agents having subjective expectations about the...

We study competition between two shopping centers that sell the same set of goods and are located at the extremes of a linear city, without restricting consumers to make all their purchases at a single place. In the case of competition between a shopping mall (set of independent single-product...

This paper studies exchange economies in which agents have differential information about the goods that the other agents bring to the market. To study such a setting, it is useful to distinguish goods not only by their physical characteristics, but also by the agent that brings them to the...

This paper studies the dynamic price competition between two firms that sell horizontally differentiated durable goods and, subsequently, provide exclusive complementary goods and services to their customers. The paper analyzes how optimal pricing strategies are affected by the existence of...

In a spatial competition model with exogenous fixed costs and divisible goods, we obtain non-Suttonian results. When the economy is infinitely replicated, the number of firms does go to infinity but, as consumers' income goes to infinity, the equilibrium number of firms tends toward a finite...
