Abstract

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 characteristics,but also by the agent that is bringing them to the market. Equilibrium is shown to exist, and characterized by the fact that agents always receive the cheapest bundle among those that they cannot distinguish from truthful delivery. Several examples are presented as an illustration.
