Discuss the laissez-faire and Keynesian schools of macroeconomic management, respectively. How do those approaches apply to the international economic systems of the pre-Bretton Woods and Bretton Woods systems? Use the systemic and subsystemic levels-of-analysis to account for the transition from the laissez-faire to Keynesian approach, post-war. Was that transition warranted, in your opinion, from the standpoint of IPE? Explain.
