In spatial competition firms are likely to be uncertain about consumer locations when launching products either because of shifting demograph- ics or of asymmetric information about preferences. Realistically distri- butions of consumer locations should be allowed to vary over states and need...

Firms are likely to be uncertain about consumer preferences when launching products. The existing literature models preference uncertainty as an additive shock to the consumer distribution in a characteristic space model. The additive shock only shifts the mean of the consumers' ideal points. We...

The paper generalizes the natural projection approach introduced by Balasko (1988) to production economies with uncertainty. It explores the equilibrium structure of the long run and short run private ownership production model. It is shown that qualitative equilibrium properties of the...

This paper shows that the inverse image of the natural projection defines a ramified covering with finite layers. Finiteness of equilibria for regular two period production economies with uncertainty follows from this property.

We develop a new model of addictive behavior that takes as a starting point the classic rational addiction model of Becker and Murphy, but incorporates uncertainty. We model uncertainty through the Wiener stochastic process. This process captures both random events such as anxiety, tensions and...

In this paper we examine the performance of theories of decision making under uncertainty/ambiguity from the perspective of their descriptive and predictive power, taking into account the relative parsimony of the various theories. To this end, we employ an innovative experimental design which...
