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...

In this paper, we determine how premium payment methods impact effective prices (prices that include any consumer payment rewards). This question is fundamentally related to policy, and we provide a robust answer by considering how a variety of retail market structures are impacted by multiple...

In this paper, we determine how a no-surcharge rule (NSR) impacts effective prices in retail markets (prices that include any consumer payment rewards). This question is fundamentally related to policy, and we provide robust answers by considering how a variety of market structures are impacted...

We provide a model in which upstream producers, whose production cost is quadratic in quantity, sell their products through two distribution channels, a traditional channel and an external retailer. Some producers (called "large" producers) supply to both channels, whereas other producers...

We consider a downstream oligopoly model with one dominant and several fringe retailers, who purchase a manufacturing product from a monopoly supplier. We then examine how the supplier's outside option influences the relation between the dominant retailer's bargaining power and the equilibrium...

We investigate a model in which a monopoly supplier distributes two types of its product through a traditional retailer with a wholesale price contract and an online retailer with an agency contract. Because such an agency contract eliminates the double marginalization problem, the online...

We propose simple dual-channel models in which an upstream manufacturer trades with a downstream retailer that is able to engage in cost-reducing activities. When the manufacturer determines whether to encroach on the downstream market after observing the retailer's effort level, the threat of...
