This intriguing collection is designed to show how economists can play a more active role in designing and directing the nation's social institutions. By taking the task of political economy seriously, the contributors (including some of today's most distinguished economists) reveal the power of economic thought to offer innovative solutions to some of the most difficult problems facing society today. By creating markets where none existed before, the authors propose efficient, reliable, and profitable improvements to current systems of health insurance, financial markets, human organ distribution, judicial practice, bankruptcy and securities regulation, patenting, and transportation. Written in the entrepreneurial spirit, these essays show economics to be an ambitious, dynamic, and far-from-dismal science.
