Eleftheria Triviza (University of Mannheim) will present her Job Market Paper “Optimal Pricing Scheme for Addictive Goods“ on January 27th at 10 AM, room QA 406 (note the room change). One-to-one meetings with the speaker can be arranged; please contact the seminar organizers, Dr. Noémie Cabau (cabau.noemie@gtk.bme.hu) and Dr. Arseniy Samsonov(samsonov.arseniy@gtk.bme.hu).  

Abstract:   

This article analyses how consumers’ habit formation and addiction affect firms’ pricing policies. I consider both sophisticated consumers, who realize that their current consumption will affect future tastes, and “naive” consumers, who do not. The optimal contract for sophisticated consumers is a two-part tariff. The main result is that the optimal pricing pattern when the consumer is naive is a “bargain then rip-off” contract, namely a fixed fee, with the first units priced below cost, and then priced above marginal cost. This holds both under symmetric and asymmetric information about the consumers’ degree of sophistication. 

Philipp Külpmann (University of Vienna) will be presenting his Job Market Paper “Identifying the reasons for coordination failure in a laboratory experiment “ (co-authored with Davit Khantadze, ISET, Tbilisi State University) on January 19th at 10 AM, room QA 406 (note the room change). One-to-one meetings with the speaker can be arranged; please contact the seminar organizers, Dr. Noémie Cabau (cabau.noemie@gtk.bme.hu) and Dr. Arseniy Samsonov (samsonov.arseniy@gtk.bme.hu).  

Abstract:   

We investigate the effect of the absence of common knowledge on the outcomes of coordination games in a laboratory experiment. Using cognitive types, we can explain coordination failure in pure coordination games while differentiating between coordination failure due to first- and higher-order beliefs. In our experiment, around 76% of the players chose the payoff-dominant equilibrium strategy despite the absence of common knowledge. However, 9.33% of the players had first-order beliefs that led to coordination failure, and another 9.33% exhibited coordination failure due to higher-order beliefs.
