We consider a monopolistic supplier's optimal choice of wholesale tariffs when downstream firms are privately informed about their retail costs. Under discriminatory pricing, downstream firms that differ in their ex ante distribution of retail costs are offered different tariffs. Under uniform...

Platforms often use fee discrimination within their marketplace (e.g., Amazon, eBay, and Uber specify a variety of merchant fees). To better understand the impact of marketplace fee discrimination, we develop a model that allows us to determine equilibrium fee and category decisions that depend...

The recent literature on oligopolistic third-degree price discrimination has been primarily concerned with rival firms' incentives to acquire customer-specific information and the consequences of such information on firm profitability and welfare. This literature has taken mostly a static view...

We here want to analyze how the imperfect competition mark-up and pass-through are transmitted through the production chain and how they change, as a function of the number of firms existing at each production stage. In order to have an analytical closed form solution, we use the standard linear...
