Exogenous factor shaping economic growth continent wide was the great power conflict. Countries falling for geographical and other reasons within the U.S. and Soviet spheres of influence felt strong pressure to adopt the same form of economic organization as their dominant partner. And how they organized their economies was the most important determinant of Western European societies' subsequent economic performance.

In a June 5, 1947, speech to the graduating class at Harvard University, Secretary of State George C. Marshall issued a call for a comprehensive program to rebuild Europe. Fanned by the fear of Communist expansion and the rapid deterioration of European economies in the winter of 1946-1947, Congress passed the Economic Cooperation Act in March 1948 and approved funding that would eventually rise to over $12 billion for the rebuilding of Western Europe.
