This welcome work argues that government is the result of a contract arrived at by individuals with varying bargaining power. Holcombe explores such issues as why the political system protects individual's rights, why individuals agree to political institutions that give their governments extensive power, and why even the most powerful government benefits from constitutional rules which constrain its power. He arrives at a theory of rights, constitutions, and government that does not rely, as economists have traditionally done, on value judgments. Very much at the cutting edge of economic thinking, this book will interest undergraduates and professionals in the fields of economics, political science, and government.
