This paper empirically analyzes how a data broker affects competition in oligopolistic product markets. It examines a unique case concerning the two dominant Finnish food retail companies’ voluntary withdrawal from information exchange via a data broker. Moreover, the companies jointly...

Exploiting exogenous variation in retail fuel prices from a temporary fuel tax discount in Germany, we estimate how the pass-through of the discount varies over space and time. We draw on daily gasoline prices of virtually all gas stations in Germany and neighboring France, with France serving...

This paper estimates a dynamic model of store adjustments in product variety that considers multiproduct service technology to evaluate the impact of entry regulations on variety and long-run profits in Swedish retail. Using rich data on stores and product categories, we find that more liberal...

This paper investigates the effects of mergers, entry, and exit in retail markets when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between manufacturers and retailers which allows for general forms of demand and retail competition. Whether...

Research shows that grocery stores reduce prices to compete with Walmart Supercenters. This study finds evidence that the competitive effects of two other big box retailers – Costco and Walmart-owned Sam's Club – are quite different. Using city-level panel grocery price data matched with a...

Liberalization in the electricity markets has been characterized by oligopoly conditions and exercise of market power, largely studied in the empirical literature on the supply side. This paper provides a new contribution to the literature on the electricity market presenting a theoretical and...

This paper investigates the effects of changes in retail market concentration when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between upstream and downstream firms which allows for general forms of demand and retail competition. Whether...

This paper develops a dynamic model of retail competition and uses it to study the impact of the expansion of a new national competitor on the structure of urban markets. In order to accommodate substantial heterogeneity (both observed and unobserved) across agents and markets, the paper first...
