In this thought-provoking collection, Professor Epstein brings together the leading articles which explore the economic approach to the two major issues of constitutionalism. The first volume deals with structural protections that are afforded by the separation of powers, the use of checks and balances, and the institutions of federalism. The second volume deals with the protection of individual rights in connection with property, speech, religion, due process and equality. Both volumes focus on the extent to which assumptions about self-interest and human nature influence the choice of social institutions. They offer extensive comparisons between the classical liberal and social democratic views of constitutional law. Professor Epstein's lengthy and careful introduction seeks to weave together the diverse approaches to constitutional law exhibited in these volumes.
