Albert Otto Hirschman (born Otto-Albert Hirschmann; April 7, 1915 – December 10, 2012) was an economist and the author of several books on political economy and political ideology. His first major contribution was in the area of development economics. Here he emphasized the need for unbalanced growth. He argued that disequilibria should be encouraged to stimulate growth and help mobilize resources, because developing countries are short of decision making skills. Key to this was encouraging industries with many linkages to other firms.
