First published in 1971 this volume applies the tools of static and of dynamic analysis (outlined in The Stationary Economy and The Growing Economy) to the control of a dynamic economy. This involves a discussion of subjects such as the theory of indicative planning, and the planning by the government of its monetary, fiscal, and incomes policies for the purposes of the short-run stabilization of the economy and of ensuring the best long-run use of the community's resources. Special emphasis is laid on the planning of such policies in conditions in which many future events remain inevitably uncertain.
