In this article we propose a two stage procedure to model demand decisions by customers who are balancing several dimensions of a product. We then test our procedure by analyzing the behavior of buyers from an Austrian price comparison site. Although in such a market a consumer will typically...

We use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price (LOOP) for identical products sold in a variety of countries. We find median deviations of twenty to fifty percent. The differences are not systematic across...

This Paper develops an argument explaining why retail prices may rise in response to the deregulation of opening hours. We make this point in a model of imperfect duopolistic competition. In a deregulated market retailers view the choice of opening hours as a means to increase the degree of...

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 compare the impact of distance, a standard proxy for trade costs, on eBay and offline international trade flows. We consider the same set of 62 countries and the same basket of goods for both types of transactions. We find the effect of distance to be on average 65 percent smaller on the eBay...

This paper documents the extent and characteristics of plants and firms in the US that are outside the manufacturing sector according to official government statistics but nonetheless are heavily involved in activities related to the production of manufactured goods. Using new data on...

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...

We combine spatial and monopolistic competition to study market interactions between downtown retailers and an outlying shopping mall. Consumers shop at either marketplace or at both, and buy each variety in volume. The market solution stems from the interplay between the market expansion effect...

We propose a dynamic model of an oligopoly industry characterized by spatial competition between multi-store retailers. 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...
