Although the study of politics dates to ancient Greece, the basic questions that interested those earliest political scientists still linger with us today: What are the origins of government? What should government do? What conditions foster effective governance? Rational choice theory offers a new means for developing correctable answers to these questions. This volume illustrates the promise of rational choice theory and demonstrates how theory can help us develop interesting, fresh conclusions about the fundamental processes of politics. Each of the book’s three sections begins with a pedagogical overview that is accessible to those with little knowledge of rational choice theory. The first group of essays then discusses various ways in which rational choice contributes to our understanding of the foundations of government. The second set focuses on the contributions of rational choice theory to institutional analysis. The final group demonstrates ways in which rational choice theory helps to understand the character of popular government.
