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 develop a dynamic entry model of multi-store oligopoly with heterogeneous markets, and estimate it using data on hamburger chains in Canada (1970–2005). Because more lucrative markets attract more entry, firms appear to favor the pres- ence of more rivals. Thus unobserved heterogeneity...

We survey the recent empirical literature on structural models of market entry and spatial competition in oligopoly retail industries. We start with the description of a framework that encompasses various models that have been estimated in empirical applications. We use this framework to discuss...

We analyze the effect of Wal-Mart's entry into the grocery market using a unique store-level price panel data set. We use OLS and two IV specifications to estimate the effect of Wal-Mart's entry on competitors' prices of 24 grocery items across several categories. Wal-Mart's price advantage over...

Dollar stores have become the fastest-growing retail format in the United States. However, there is considerable controversy regarding their entry, particularly into markets without grocery stores, and concerns that dollar-store entry decisions are motivated by preemptive incentives. In this...

We examine the implications of different contractual forms for welfare as well as for firms’ profits in a framework in which a vertically integrated firm sells its good to an independent downstream firm. Under downstream Bertrand competition, the standard result of the desirability of two-part...

This paper examines retail grocery price levels across a large panel of stores in Sweden. We explain price variation across stores by market structure variables to capture differences in competition intensity and a number of store- and region-specific factors. Most of the explained variation in...

In many telecommunications markets incumbent providers enjoy a demand-side advantage over any entrant. However, market entrants may enjoy a supply-side advantage over the incumbent, since they are more efficient or operate on innovative technologies. Considering both a supply-side and a...

We examine incentives of bottleneck facility holders to manipulate access charge accounting in free entry downstream markets. We consider the situation wherein one firm holds an upstream bottleneck facility and new entrants use it at the regulated price (access fee) to provide final products....
