This paper analyses the strategic use of fixed costs to deter entry or monopolize a market in a standard Cournot framework. First of all a general case shows how the presence of fixed costs can affect the possible equilibria to the Cournot game. It is shown that the presence of a firm with a...

Event study analysis is a branch of econometrics which attempts to measure the effects of economic events on the value of firms by examining stock market data. Providing that share prices reflect the underlying economic values of assets, changes in equity values will properly capture expected...

Behavioural and industrial economists have argued that, because of cognitive limitations, consumers are liable to make sub-optimal choices in complex decision problems. Firms can exploit these limitations by introducing spurious complexity into tariff structures, weakening price competition....

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...

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 presents an experimental study of dynamic indefinite horizon R and D races with uncertainty and multiple prizes. The theoretical predictions are highly sensitive: small parameter changes determine whether technological competition is sustained, or converges into a market structure...

A criminal offence requiring Ghosh dishonesty was introduced in the UK by the Enterprise Act 2002, primarily to enhance cartel deterrence as a complement to corporate fines. Yet the first convictions resulted from a US plea bargain in 2008. This paper identifies three obstacles to enhancing...

This paper presents a model in which a firm attempts to gain market power by pricing above the competitive market price and simply trying to persuade ill-informed consumers not to search for other lower priced firms. Fictitious price comparisons, or false sale signs could be used in this way to...

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...
