Constitutional economics is the academic sub-discipline of economics and constitutionalism. It is often described as "the economic analysis of constitutional law." Constitutional economics tries to explain the selection of different constitutional rules "limiting the choices and activities of economic and political agencies." This is different from the approach of traditional economics. Also, constitutional economics studies how well economic decisions of the state agree with the existing constitutional economic rights of its citizens." For example, proper distribution of economic and financial resources of the state is a big question for every nation. Constitutional economics helps finding a legal mechanism to solve this problem.
