Electronic marketplaces (e-marketplaces) allow networks of buyers and sellers to conduct business online and to exchange information more efficiently using Internet technology. Despite the benefits that e-marketplaces potentially afford firms, concerns have been raised that these markets may...

This paper demonstrates that the Most-Favoured-Customer (MFC) clause identified in the Monopolies and Mergers Commission (MMC) Report on Foreign Package Holidays behaves not like an MFC but rather as if it was a variant of a so far unstudied price matching guarantee. This provides a clearer...

The paper reports on results from a public survey on attitudes to collusion and cartel enforcement in Britain. Respondents demonstrate an understanding that price-fixing is harmful and should be punished. While there is strong support for high corporate fines and naming and shaming, only 1 in 10...

This paper explores and quantifies the link between marketing and rulings on competition or antitrust law made by UK competition or antitrust authorities. This examination is timely due to both the changing form and increasing severity of competition law in the UK and the strong associations...

In this paper, a dominant supplier and competitive fringe supply goods to a common buyer who has private information about the state of demand. We give conditions under which market-share contracts are profitable, and we show that, in some cases, the full-information outcome can be obtained...

Delineation of the relevant market forms a pivotal part of most antitrust cases. The standard approach is sequential. First the product market is delineated, then the geographical market is defined. Demand and supply substitution in both the product dimension and the geographical dimension will...
