I examine the factors facilitating or hindering collusion using a comprehensive data set on the incidence 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...

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 for four-digit industries over...

This paper examines the impact of price competition on advertising/R&D expenditure and market structure. General theoretical results are derived which restrict the space of possible outcomes regarding the behaviour of concentration and advertising/R&D expenditure following an intensification of...

"I analyze the effects of downstream competition when there is bargaining between downstream firms and upstream agents (firms or unions). When bargaining is over a uniform input price, a decrease in the intensity of competition (or a merger) between downstream firms may raise consumer surplus...

This paper examines the effect of the intensity of short-run price competition and other exogenous variables that affect gross profit margins-such as the degree of product differentiation and the consumers' responsiveness to quality-on market structure and on advertising and R&D expenditure. A...

Using a comprehensive dataset on the incidence of price-fixing across British manufacturing industries in the 1950s, I compare collusive and competitive industries and find evidence of a negative relationship between collusion and the labour productivity of larger firms relative to smaller...
