We introduce a two-period economy with asymmetric information about the state of nature that occurs in the second period. Each agent is endowed with an information structure that describes her (incomplete) ability to prove whether or not a state has occurred. We show that if the number of states...

Private state verification is introduced in a two-period economy with spot markets in both periods and complete futures markets for contingent delivery in the second period. Existence of equilibrium is established, under standard assumptions. An example is presented in which a complete set of...

We introduce asymmetric information about consumers' transportation costs (i.e., the degree of product differentiation) in the model of Hotelling (1929). When the transportation costs are high, both firms have lower profits than in the case of perfect information. Contrarily, both firms may...

We propose the notion of objects of choice as uncertain consumption bundles, extending the formulation of Arrow (1953). Agents sign “contracts for uncertain delivery”, which specify a list of alternative bundles, instead of a single one. This allows us to incorporate uncertainty and...

The notion of uncertain delivery is extended to study exchange economies in which agents have different abilities to distinguish between goods (for example a car in good condition versus a car in bad condition). In this setting, it is useful to distinguish goods not only by their physical...
