The author affirms that (1) multi-sectoral nature of the ERP policy required non-partisan coordination among different actors with different economic ideas, especially led by economic experts.; (2)In order to strike a balance of competing demands for the ERP policy(reconstruction, development, security), the idea of ordoliberalism functioned as a focal point of consensus. The reason was that the idea, originally developed in prewar Germany, stresses the need for the state to ensure a balance between market liberalization, investment (civil &military) and balance of payments. (3) The penetration of ordoliberalism over Western Europe through the ERP could explain an "ideational leap" from a German to a European paradigm of integration, in that it became one of the central thought for European integration at an early stage, such as in the ECSC, competition policy and etc.
The argument of the paper is expected to pose another possibility of European institutions, based on an idea different from market liberalism, Keynesianism, dirigisme, or socialism. In addition, it sheds a new light on unexplored linkages between domestic, European and international political economy in postwar embedded liberalism.
