Global EconomyThe bringing together of different parts of the world into one economic system, in which the separate areas are interdependent. Towards the end of the Second World War the great powers were planning for the future and were determined that there should not be another Great Depression like that in the 1930s, when the international trading and financial system broke down. The US was the dominant voice and at Bretton Woods (1944) set up the IMF (International Monetary Fund) and World Bank, both under US control, to promote international investment and exchange rate stability and to deal with balance of payments problems. GATT (General Agreement on Tariffs and Trade), established in 1947, reduced tariffs and began an era of free trade.
