Professor Shackle (1903-1992) was best known for his extensive and scholarly work on the theory of the making of business decisions in conditions of uncertainty. He also made important contributions to the theory of rates of interest and showed an exceptional ability to combine theoretical work with a practical understanding of the business world. Professor Shackle believed that economics is not pure logic but is part of the endeavour to describe the integral nature of man. Originally published in 1966, this volume contains a collection of his articles, all concerned in some way to show his approach to economic thought.
