For many years, Dr Irwin Stelzer, the economic commentator and journalist, has been stimulating audiences around the world with lectures on a range of economic topics. In this volume, the IEA reprints revised versions of twelve lectures in three areas where Dr Stelzer is acknowledged as an expert - competition policy and the form it should take; the proper place of regulation in competitive and monopolised markets; and the content of energy and environmental policies. The essays contain many positive proposals for extending the reach of competitive markets and they comprehensively refute some major economic fallacies. This is a stimulating collection of ideas from one of the foremost economic commentators of the day.
