Should the FTC have allowed Zillow to acquire its foremost rival, Trulia? It is increasingly well-accepted that digital platforms tend toward dominance in their immediately adjacent relevant-product markets. Google, for example, has long held a majority share of the markets for general-search...

In product markets, there exists substantial dispersion in prices for transactions of physically identical goods, and incumbent sellers sell at higher prices than entrants. This study develops a theory of dynamic pricing that explains these facts as results from the same fundamental friction:...

Consumers heterogeneously possess limited price information: captive consumers may know only one price from a seller, while informed consumers know several prices. We study a homogeneous-good oligopoly where sellers of heterogeneous costs compete on price for heterogeneously limit-informed...

We consider the Salop (1979) model of product differentiation and assume that consumers are uncertain about the qualities and prices of firms’ products. They can inspect all products at zero cost. A share of consumers is expectation-based loss averse. For these consumers, a purchase plan,...

This paper investigates the impact of the largest rail strikes in German history on intercity buses - a then newly liberalised market. Using unique booking data of bus services, we exploit variation in rail service cancellations across routes to show that the disruption in rail transport...

This paper analyzes fairness and bargaining in a dynamic bilateral matching market. Traders from both sides of the market are pairwise matched to share the gains from trade. The bargaining outcome depends on the traders’ fairness attitudes. In equilibrium fairness matters because of market...

Especially in many online markets, consumers can readily observe prices, but may need to further inspect products to assess their suitability. We study the effects of product differentiation and search costs on competition and market outcomes in a tractable model of price-directed consumer...

Within a one-shot, duopoly game, we show that firms cannot use false in-store price comparisons to deter rational consumers from further beneficial price search in an effort to create market power. However, by introducing a consumer protection authority that monitors price comparisons, we...
