This paper evaluates alternative strategic models of competition and market structure inonline retailing, and makes comparisons with traditional retailing. Online consumers areless concerned than traditional consumers about spatial characteristics and moreconcerned about hidden quality...

We investigate the effect of market structure on market performance in the market for consumer electronics. This research is novel, because we exploit product life cycle information to build an instrumental variable for the number of firms in a market, a variable which hitherto had to be treated...

We investigate the causal effect of market structure on market performance in the consumer electronics. We combine data from Austria's largest online site for price comparisons with retail data on wholesale prices provided by a major hardware producer for consumer electronics. We observe input...

Does the internet increase competition? To address this question, I exploit two institutional details unique to Germany: (1) Some municipalities received glass fibre cables that cannot be upgraded to DSL; I use these municipalities as a treatment group with reduced online competition. (2) German...

Gasoline prices in many markets follow a saw-toothed pattern known as an Edgeworth Cycle. Lewis (2009) introduces a novel way of measuring the shape of the cycle, the median change in price, and regresses this against a number of explanatory variables in US markets. Here, we undertake a similar...

We consider a model of vertical competition where downstream firms (retailers) purchase an upstream input from a monopolist and are able to differentiate from each other in terms of quality. Our primary focus is to study the effects of introducing a large retailer, such as a Wal-Mart...

While online consumers are less concerned than traditional consumers about firm location, they may be more concerned about unobservable quality and, to signal this, online retailers rely more on advertising than traditional retailers. Imperfect price competition may arise because of vertical...

The structure of a gasoline market can be an important element in the pricing choices of its participants. However, structure is often measured only indirectly by, for example, the number of independent sellers, or by seller density. Here we present a more direct and literal way of exploring...

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...
