We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogenous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on...

This paper studies price discrimination using observables that are manipulable by the buyers at a cost. Rather than deterring manipulation, the optimal price discrimination mechanism (OPDM) offers each observable a personalized price that induces the buyers to pretend to have a lower valuation....

The most pressing debates in antitrust today center on major platforms like Amazon, Google, and Facebook. Platform markets are subject to strong network effects, which tend to create barriers to entry and reinforce market power. Frequently, the only way for a new platform to enter the market...

Implantable medical device manufacturers are able to directly price discriminate by setting different prices for the same product in different hospitals. I analyze the welfare effects of this form of price discrimination in the case of Implantable Cardioverter Defibrillators (ICDs). I find that...

This paper considers European airline markets to establish a causal effect of competition on pricing dynamics. It shows that intertemporal price dispersion is strongly reduced by competition because flights booked close to departure time are on average priced substantially lower when competition...

We study a sequential screening problem in which the information structure is characterized by neither first-order stochastic dominance (FOSD) nor mean-preserving spread (MPS). Specifically, we refer to a procurement contract with privately known mean and spread of cost distribution. The...

What are the effects of banning price discrimination in input markets? This paper considers the potential exclusionary effects of such policies, i.e., whether a restriction to uniform pricing leads a supplier to foreclose some downstream firms. In particular, I study how the conditions for...

Implantable medical device manufacturers are able to directly price discriminate by setting different prices for the same product in different hospitals. I analyze the welfare effects of this form of price discrimination in the case of Implantable Cardioverter Defibrillators (ICDs). I find that...

We consider a duopoly model where firms can identify only a share of consumers, which is positively correlated with the consumer’ preferences. Firms charge personalized prices to the consumers they can recognize and a uniform price to the rest of consumers. The firms’ available information...

This paper studies the role of loss-averse consumers' expectations about their future consumption in the pricing policy of a monopolistic firm in a dynamic setting. The firm offers a contract consisting of two units of service and the consumer makes two sequential consumption choices: to buy the...
