Karl Gunnar Myrdal was a Swedish economist who received the Nobel Prize in Economics in 1974. He is known for his theories of cumulative causation, backwash effects, and the need for government intervention to promote balanced regional development. According to Myrdal, free market forces tend to increase inequalities between developed and underdeveloped regions. The backwash effects of economic activity in developed regions drain wealth from poorer regions in a vicious cycle of underdevelopment.
