Constitutional economics
Constitutional economics is a program of joint study of economics and constitutionalism. It is often described as "the economic analysis of constitutional law." Constitutional economics tries to explain the selection of 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 tries bringing together constitutional economic rights of the citizens and economic policy of the state.
