This paper examines retail grocery price levels with a very large (unbalanced) panel of stores that operate in well-defined local markets. We explain price variation across grocery retailers by the concentration of wholesalers and retailers, and the market share of hypermarkets (and control for...

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...

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...

We use a dynamic oligopoly model of entry and exit with store-type differentiation to evaluate how entry regulations affect profitability, market structure and welfare. Based on unique data for all retail food stores in Sweden, we estimate demand, recover variable profits, and estimate entry...

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...

This study is a theoretical examination of whether employee‐controlled firms (ECFs) enter a free‐entry oligopolistic market excessively or insufficiently, from the viewpoint of welfare maximization. The excess entry theorem is well known in oligopoly theory. According to this theorem, a...

When firms set prices and face entry costs, efficiency in production and in entry are not simultaneously achieved, generating the possibility that regulatory interventions can lead to efficiency enhancements. We show through the Bertrand model that in markets with public entry and regular...

The so-called excess-entry theorem (Mankiw and Whinston 1986, Suzumura and Kiyono, 1987) establishes conditions guaranteeing that more firms enter a homogeneous Cournotoligopoly in equilibrium than a benevolent government prefers. We generalise the approach and analyse the behaviour of a...

We propose a dynamic model of an oligopoly industry characterized by spatial competition between multi-store firms. Firms compete in prices and decide where to open or close stores depending on demand conditions and the number of competitors at different locations, and on location-specific...

This paper proposes and tests a model of supermarket competition based upon John Sutton's (1991) endogenous fixed cost (EFC) framework. The relevance of the EFC framework to supermarket competition stems from the industry's surprisingly uniform competitive structure: irrespective of the size of...
