This original collection comprises the first comparative study of competition policy, an area which has emerged as a vibrant and influential discipline within the study of economic policy and policy-making. The victory of market economics means that every capitalist country has created or intensified competition policy. The study compares the six 'model' policy regimes of the USA, Germany, Japan, the UK, Canada, and the European Union. The role of institutions and political process in controlling monopolies, cartels, and mergers is emphasised. the case for convergence and the emergence of a global regime is evaluated. Cutting through the traditional arena of lawyers and economists, this edited volume provides incisive political analysis of the mechanics of international competiton policy. It is an exciting and original new look at how policy is formed on the international stage.
