This study synthesizes and summarizes the theoretical arguments and empirical evidence that suggest that competition works remarkably well to reduce costs and improve efficiency and innovation, even in an arena where competition has typically been ignored--government-financed services. The arguments and data marshaled here, drawn primarily from the American experience, portray the substantial benefits to consumers and taxpayers that can result from efforts to increase competition in commercial services previously operated as government monopolies.Competition in Government-Financed Services will help fortify the efforts of competition advocates, both in the United States and in the emerging market economies of Eastern Europe and the developing world, to get on with the job of strengthening competition and opening their systems to market forces.
