This paper examines the impact of price competition on advertising/R&D expenditure and market structure. A general theoretical result is derived, which restricts the space of possible outcomes regarding the behaviour of concentration and advertising/R&D expenditure following an intensification...

I analyse the effects of a downstream merger in a differentiated oligopoly when there is bargaining between downstream firms and upstream agents (firms or unions). Bargaining outcomes can be observable or unobservable by rivals. When competition is in quantities, upstream agents are independent...

This paper examines the effect of price competition on innovation, market structure and profitability in R&D-intensive industries. The theoretical predictions are tested using UK data on the evolution of competition, concentration, innovation counts and profitability over 1952-1977. The...

Policies to promote competition are high on the political agenda worldwide. But in a constantly changing marketplace, the effects of more intense competition on firm conduct, market structure, and industry performance are often hard to distinguish. This study combines game-theoretic models with...

This paper examines the impact of firms' conduct on market structure. It studies the evolution of concentration in UK manufacturing following the abolition of cartels using a theoretical framework based on Sutton's theory of market structure and a panel data set of four-digit industries over...

This paper provides an analysis of factors facilitating or hindering collusion using data on the occurrence of price-fixing across UK manufacturing industries in the 1950s. The econometric results suggest that collusion is more likely the higher the degree of capital intensity and less likely in...

I examine the impact of competition on wages and productivity using a panel data set of U.K. manufacturing industries over 1954-1973. The introduction of cartel law in the United Kingdom in the late 1950s caused an intensification of price competition in previously cartelized manufacturing...

This paper surveys the empirical literature on the links between innovation, market structure and firm size. The review shows that there is little evidence in support of the Schumpeterian hypothesis that market power and large firms stimulate innovations: R&D spending seems to rise more or less...
