We investigate the continuity of equilibrium in differential information economies with a finite number of agents. In this setting, agents can make contingent contracts based on events that are commonly observed. With private information modelled as finite partitions of a compact and metrizable...

We give an illustration of hysteresis (path-dependence) in a simple economy. In the presence of multiple possible equilibrium prices, we find that past expectations determine present prices. This phenomenon of path-dependence is robust under perturbations of the economy.

An economy with ex ante markets for future delivery contingent on ex post spot market prices is considered. Since spot prices are publicly observed ex post, this framework bypasses the enforcement problems that may arise as a result of differential information about states of nature....

In the presence of events that are seen as ambiguous by all agents in an economy, if preferences are representable by expected uncertain utility functions (Gul and Pesendorfer, 2014), general equilibrium does not typically exist.

We study general equilibrium with private and incomplete state verification. Trade is agreed ex ante, that is, before private information is received. It is useful to define a list of bundles as a derivative good that gives an agent the right to receive one of the bundles in the list....

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...

The issue of cheating is a serious problem since it can call the efficiency of an education system into question. Furthermore, it is a devaluing factor in the country's stock of human capital. A student who copies is a free-rider, in the sense that he/she gains a higher grade than that merited...

In economies with uncertain delivery, agents trade their endowments for lists instead of bundles. A list specifies a set of bundles such that the agent has the right to receive one of them. In this paper, with continuity conditions on private beliefs about the bundle that will be delivered, we...

In an economy with private information, we introduce the notion of objects of choice as lists of bundles out of which the market selects one for delivery. This leads to an extension of the model of Arrow-Debreu that is used to study ex-ante trade with private state verification. The model does...

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...
