Implications for Policy

  • W. A. Eltis

Abstract

It is always dangerous to jump too rapidly from theory to policy. In a memorable passage which many economists must have taken to heart in recent years, Keynes wrote in 1930, six years before the General Theory:

…it is characteristic of economics that valuable and interesting work may be performed and steady progress made for many years, and yet that the results will be almost useless for practical purposes until a certain degree of exactness and perfection has been reached. Half-baked theory is not of much value in practice, though it may be half-way towards final perfection.1
