We develop a market model which explains how prices react to short-run demand variations when the number of active price-setting firms is held fixed on its long-run level. We assume that for each firm the average production cost function is U-shaped, that customers are imperfectly informed about...

I propose a model of the housing market using a search framework with asymmetric information in which sellers are unable to commit to asking prices announced ex ante. Relaxing the commitment assumption prevents sellers from using price posting as a signalling device to direct buyers' search....

Unternehmen nutzen Daten zur Optimierung von Preisen. Mit zunehmender Kenntnis individueller Kundenprofile könnte der Spielraum steigen, Individuen gezielt über personalisierte Angebote anzusprechen. Die wettbewerblichen Effekte sind ambivalent: Personalisierte Preise können zur Ausbeutung im...

Extreme adverse selection arises when private information has unboundedsupport, and market breakdown occurs when no trade is the only equilibriumoutcome. We study extreme adverse selection via the limit behavior of afinancial market as the support of private information converges to an...

Ausgangspunkt für Forderungen nach einer Einführung von Kapazitätsmechanismen im deutschen Strommarkt ist die Beobachtung, dass das gegenwärtige Investitionsverhalten der Marktakteure zu einem unzureichenden Niveau der Stromversorgungssicherheit führen könnte. In dem vorliegenden Beitrag...

We study mergers in a market where N firms sell a homogeneous good and consumers search sequentially to discover prices. The main motivation for such an analysis is that mergers generally affect market prices and thereby, in a search environment, the search behavior of consumers. Endogenous...

This paper is the first to examine the effect of minimum price guaranteesin a sequential search model. Minimum price guarantees are notadvertised and only known to consumers when they come to the shop.We show that in such an environment, minimum price guarantees increasethe value of buying the...

Despite the mixed empirical evidence, many economists stillhold to the view that Internet will promote competition betweenfirms,thereby lowering prices and increasing economic welfare. This paperpresents a search model that provides a different view. We analyzethemarket for a homogeneous good...
