In this article we study patterns of vertical product differentiation in a multi-product monopoly using a random utility model. Prior research shows that applying such a model in a multi-product setting implies symmetric patterns of product differentiation in which all product variants of a...

This paper investigates how increases in concentration can be interrupted or reversed by changes in how firms compete on quality. We examine the U.S. hotel industry during the past half century. We document that starting in the early 1980s, quality competition came more in the form of costs that...

Electronic commerce and flexible manufacturing allow personalization of initially standardized products at low cost. Will customers provide the information necessary for personalization? Assuming that a consumer can control the amount of information revealed, we analyse how his decision...

A small number of firms have a large market share in the Austrian food retailing market. Market concentration has been growing over the last years which has raised concerns about market power. Previous studies on price setting behaviour in the food retailing market were at the national level and...

This paper highlights the importance of "centrality" for pricing. Firms characterised by a more central position in a spatial network are more powerful in terms of having a stronger impact on their competitors' prices and on equilibrium prices. These propositions are derived from a simple...

We extend the 'no-haggling' result of Riley and Zeckhauser (1983) to the class of linear multiproduct monopoly problems when the buyer's valuations are smoothly distributed. In particular we show that there is no loss for the seller in optimizing over mechanisms such that all allocations belong...

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 characterize a monopolist's optimal offer of service plans when only informed customers know already at the contracting stage whether their demand is high or low, while uninformed customers may learn their demand only after incurring some costs, if at all. While informed customers purchase...
