Public choice theory has become an increasingly significant aspect of public law scholarship. A more comprehensive knowledge of public institutions and their activities can illuminate our understanding of how legal rules shape the behavior of these institutions. This volume gathers together key papers highlighting the fundamental issues in the evolution of this subject. Besides providing an appreciation of the institutional complexity and potential weak points of democracies, public choice theory promises to show how political structures and processes shape outcomes for better or for worse. It thereby aids understanding and improvements to institutional design. Much of that design is expressed in the form of law, so the subject is of particular importance to legal scholars. This authoritative selection of articles provides a firm foundation to this important area of study.
