Online review aggregators, such as TripAdvisor, HotelClub and OpenTable help consumers identify the products and services that best match their preferences. The goal of this study is to understand the impact of online review aggregators on firms and consumers. We adopt Salop's circular city...

In this paper, we study the rational for an incumbent to launch a second brand when facing potential entry in a market with quality differentiated products and a fringe producer. Depending on market size, costs for a second brand and a potential entrant's setup cost the incumbent might use a...

Firms that must choose capacity in advance of observing uncertain or time varying demand sometimes have more inventory than their full price customers will consume. By pricing a limited quantity at below market clearing rates, “rationed promotions” allow sellers to recruit enough excess...

The past few years have witnessed the increasing ubiquity of user-generated content on seller reputation and product condition in Internet based used-good markets. Recent theoretical models of trading and sorting in used-good markets provide testable predictions to use to examine the presence of...

The unprecedented access of firms to consumer level data facilitates more precisely targeted individual pricing. We study the incentives of a data broker to sell data about a segment of the market to three competing firms. The segment only includes a share of the consumers in the market around...

"Hard discounters" are retail formats that set retail food prices even lower than existing discount formats, such as Walmart and Target. Offering limited assortments and focusing on store-brands, these formats promise to change the competitive landscape of food retailing. In this paper, we study...

The unprecedented access of firms to consumer level data not only facilitates more precisely targeted individual pricing but also alters firms' strategic incentives. We show that exclusive access to a list of consumers can provide incentives for a firm to endogenously assume the price leader's...

Data brokers collect, manage, and sell customer data. We propose a simple model, in which data brokers sell data to downstream firms. We characterise the optimal strategy of data brokers and highlight the role played by the data structure for co-opetition. If data are "sub-additive", with the...

Experimental evidence suggests that consumers are affected by reference prices and by relative price differences ("relative thinking"). A linear-city model of two retailers that sell two goods suggests how this consumer behavior affects firm strategy and market outcomes. A simple model analyzes...
