How successful was the European Recovery Program? Western Europe indubitably recovered, and precisely over the period (1948–1951) of the Marshall Plan. By 1949 French industrial and agricultural production both exceeded 1938 levels for the first time. By the same criterion sustained recovery was achieved in 1948 by the Netherlands, in 1949 by Austria and Italy, in 1950 by Greece and West Germany. Of those countries occupied during the war, only Belgium, Denmark and Norway recovered sooner (in 1947). Between 1947 and 1951 the combined GNP of western Europe rose by 30 percent.
