G. L. S. Shackle: The Dissenting Economist's Economist by J. L. Ford is a major new intellectual biography which places Shackle's work in context, assessing the importance of his long and prolific career. An opponent of much of the equilibrium-centred orthodoxy in economics, the overwhelming concern of Shackle's work was the nature of time. In his view, too much of economic theorising was concerned with a rigid, Newtonian definition of time, rather than one which emphasised human expectations and uncertainty. Central to his theory was a rejection of the notion of probability for unique decisions and its replacement by his own measure of uncertainty, the degree of potential surprise. This important book charts the development of these ideas and their impact on his important work on the theory of interest rates, industrial investment, the business cycle, and the understanding and application of Keynes's economics. It will be welcomed by historians of economic thought and all other economists, orthodox and non-orthodox alike, concerned with the pioneering work of one of the most important economists of our time.
