The CMA's report on competition and market power in UK labour markets provides insights into the concentration and market power in various industries. It discusses the benefits of well-functioning labour markets for economic growth and the potential for collusion between firms to set wages, which may be illegal under competition law. The report also examines the prevalence of non-compete agreements, the rise of the gig economy, and the link between product market power and labour market power. The implications of the report are important for competition law advisors, particularly in relation to wage-setting practices and the potential for collusion in labour markets.
