These thirtyone essays form the foundation of 1986 Nobel Laureate James M. Buchanan's work on the constitutional economics paradigm he founded. Following the earlier collection, Economics: Between Predictive Science and Moral Philosophy, these essays include many that appeared in journals not easily accessible as well as some which have not previously been published.The volume is organized in two parts: theoretical foundations and applications. The latter part includes papers on aspects of voting, monetary and fiscal constitutions, public goods supply, taxation and public debt, and property rights and externalities. This edition provides easier access and gives a wider exposure to a set of arguments and ideas that mark important steps in Buchanan's building of the Constitutional Economics Paradigm.The vision of a new political economy developed and applied in the contributions of this volume will be of interest to scholars and students of economics as well as other disciplines from political science to philosophy, providing a valuable perspective and orientation to anyone who is concerned with the practical issues of policy making.
