Comparative economic systems
（重定向自Comparative economics）
Comparative economic systems is the subfield of economics dealing with the comparative study of different systems of economic organization, such as capitalism, socialism, feudalism and the mixed economy. It is widely held to be founded by the economist Calvin Bryce Hoover. Comparative economics therefore consisted mainly of comparative economic systems analysis before 1989 but switched substantially its efforts to comparison of the economic effects of the transition experience from socialism to capitalism.
