We correct an omission in the definition of the domain of weakly responsive preferences introduced in Klaus and Klijn (2005) or KK05 for short. The proof of the existence of stable matchings (KK05, Theorem 3.3) and a maximal domain result (KK05, Theorem 3.5) are adjusted accordingly.

In this paper we analyse the role of asymmetric information between firms and consumers about market conditions.

In this paper we consider the spatial model by Anderson and Neven (1991) to study the subgame perfect equilibria without restricting the consumers' reservation price. New equilibria emerge where firms locate at disperse points in space. Also, at equilibrium, firms may monopolize some segments of...

We study the effects of varying the confidence level of speculators and the confidence level attributed to them by their competitors, about the precision of their private information in the framework of the model of financial markets with imperfect competition a la Kyle (1989).

We consider social choice rules which select a lottery over outcomes for each progile of individual preferences. Agents are assumed to have preferences over lotteries satisfying the axioms of expected utility. We exhibit a large class of rules satisfying strategy- proofness.

We study the relation between the number of firms and price-cost margins under price competition with uncertainty about competitors' costs. We present results of an experiment in which two, three and four identical firms repeatedly interact in this environment. In line with the theoretical...
