This two-volume set brings together for the first time a collection of seminal writings dealing with the development of competition policy in Europe, the United States and Japan. It begins by reproducing the writings of leading philosophers and scholars on the rationale and desirability of competition in market economies. These interpretations range in time of origin from ancient Greece through to Adam Smith and James Madison to very recent contributions in the competition policy debate. Having established relevant philosophical foundations, the compendium presents analyses by leading British, American, German and Japanese scholars on the interpretation and administration of laws concerning price-fixing and other restrictive agreements, market dominance and monopolization, predatory practices and mergers.
