In 1962, economists James M. Buchanan and Gordon Tullock published The Calculus of Consent, in which they developed the principles of public choice theory.  In the fifty years since its publication, the book has defined the field and set the standard for research and analysis.  To celebrate a half-century of scholarship in public choice, Dwight Lee has assembled distinguished academics from around the world to reflect on the influence of this monumental publication, and, more broadly, the legacy of its legendary authors.  Their essays cover a broad spectrum of topics and approaches, from the impact of public choice theory on foreign policy analysis to personal remembrances of learning from and collaborating with Buchanan and Tullock.  The result is a unique collection of insights that celebrate public choice and its visionary proponents, while considering its future directions.
