The high growth rate in many industrial countries during the first two decades after World War II produced a financial expansion, which in its turn made possible an extension of the growth process. But it also led to a financial crisis, when increasing costs during the 1970s created growing deficits in the balance of payments and the government budgets in many countries. This volume adopts a disequilibrium approach for analyzing the inter-relation between real and financial development, in a world where agents are not able to realize their plans. The authors take as their starting point the theoretical world of Keynes and the Stockholm School, since the modern disequilibrium analysis, in their view, often disregards the financial side of the economy.
