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...

In economies with uncertain delivery, objects of choice are lists of bundles instead of bundles. Agents trade their endowments for lists, and it is the market that selects one of the bundles in the list for actual delivery. Knowledge of the selection mechanism allows agents to predict the bundle...

We characterize the core and the competitive allocations of a continuum economy as strong Nash equilibria of an associated game with only two players.

Radner (1968) proved existence of a competitive equilibrium for differential information economies with finitely many states. We extend this result to economies with infinitely many states of nature. Each agent observes a public and a private signal. The publicly observed signal may take...

We consider a differential information economy with infinitely many commodities and analyze the veto power of the grand coalition with respect the ability of blocking non-Walrasian expectations equilibrium allocations. We provide two different Walrasian expectations equilibrium equivalence...

In this paper we consider an exchange economy where there is an external restriction for the consumption of goods. This restriction is defined by both a cap on consumption of certain commodities and the requirement of an amount of rights for the consumption of these commodities. The caps for...

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...

We consider a general equilibrium model of trade ex ante with differential information in which agents choose plans of state-contingent lists of bundles. Being unable to verify that the state of nature is s and not t, an agent has to accept the delivery of any bundle in the list for delivery in...
