We analyze dynamic price competition in a homogeneous goods duopoly, where consumers exchange information via word-of-mouth communication. A fraction of consumers, who do not learn any new information, remain locked-in at their previous supplier in each period. We analyze Markov perfect...

We introduce a dynamic price competition model for duopsony. Each buyer receives a privately observed profit shock in each period and uses a publicly observable and retroactive price to entice sellers to sell to her in the upcoming period. The price competition scheme captures sellers’...

We study a discrete time dynamic game of price competition with spatially differentiated products and price adjustment costs. We characterise the Markov perfect and the open-loop equilibrium of our game. We find that in the steady state Markov perfect equilibrium, given the presence of...

In markets with imperfect information and heterogeneity, the information technology affects the rate at which agents meet, which in turn affects the distribution of production technologies across firms. We show that in models for such markets there are typically multiple equilibria because...

This paper studies the consequence of an imprecise recall of the price by the consumers in the Bertrand price competition model for a homogeneous good. It is shown that firms can exploit this weakness and charge prices above the competitive price. This markup increases for rougher recall of the...

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...
