Price levels and movements on gasoline and diesel markets are heavily debated among consumers, policy-makers, and competition authorities alike. In this paper, we empirically investigate how and why price levels differ across gasoline stations in Germany, using eight months of data from a novel...

We use a novel data set with exact price quotes from virtually all German gasoline stations to empirically investigate how a temporary variance in local market structure induced by restricted opening hours of specific players affects price competition. We find that, during their hours of...

We analyze a situation in which two horizontally differentiated firms compete in two-part tariffs (i.e., a linear and fixed price), and some consumers are not informed about the linear per-unit price. We show that there is a non-monotone relationship between the degree of consumer-side...

Drip pricing is the business practice of decomposing the price into multiple components which are presented sequentially to buyers. We experimentally examine the effects of this practice on seller strategies and buyer behavior as well as the implications for regulation. Sellers set two prices: a...

Retailer bargaining power is an important aspect of many international antitrust investigations. Size and market share analysis are often the cornerstones of bargaining power identi cation. However, other factors, like consumer behavior, i.e. "one-stop shopping", can heavily a ect the bargaining...

We consider a situation of duopolistic competition in which one firm may (falsely) advertise high product quality. Consumers are heterogeneous. One group forms rational beliefs about quality, whereas some consumers are naive and fully trust any advertisement. We compare two scenarios in which...

We analyze and compare the incentives to collude under different pricing schemes in a differentiated-products market where customers have elastic demand. We show that allowing firms to set two-part tariffs as opposed to linear prices facilitates collusion at maximum prices independent of the...
