Looking at a large number of markets, I find that (i) prices and variety are higher when there are two competing supermarkets than in those with a single store and (ii) the two effects are positively correlated. This pattern persists after controlling for differences across markets in a variety...

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...

This article provides a tractable model of inter-temporal price-discrimination by heterogeneous firms, imperative for our understanding of advance purchase markets in the wake of entry. The pricing schedule of a more efficient entrant is found to differ systematically from the pricing schedule...

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...

We use a dynamic oligopoly model of entry and exit to evaluate how entry regulations affect profitability and market structure in retail. The model incorporates demand and store-level heterogeneity. Based on unique data for all retail food stores in Sweden, we find that the average entry costs...

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 studies the relationship between retail gasoline pricing strategies and potential demand. Utilising detailed data on traffic on the German Autobahn and the special case of Bundesautobahntankstellen, the interaction between demand and price competition is studied, as are the changes in...

This paper empirically analyzes the effects of competition on price and non-price dimensions on the example of superstore entries. Using a rich retail panel from 2006 to 2016 and a data set documenting locations and opening dates of superstores, allows to identify competitive effects with the...

Increasingly, retailers have access to better pricing technology, especially in online markets. Firms employ automated pricing algorithms that allow for high-frequency price changes. What are the implications for price competition? We develop a model of price competition where firms can differ...

This paper explores airline pricing behaviour dealing with two issues. The first is to measure the extent to which intramodal competition influences fares charged to travellers. The second is to shed light on fares' intertemporal profile to verify if airlines undertake intertemporal price...
