Garrison on Keynes

The Quarterly Journal of Austrian Economics

Volume 18, Number 1 (Spring 2015)

ABSTRACT: This paper examines Roger W. Garrison’s interpretation of John Maynard Keynes. Garrison has given economists a useful way to illustrate Keynes’s theory, but there are two fundamental problems with Garrison’s interpretation. First, the shape of the Hayekian triangle cannot be fixed in Keynes’s theory. Second, Garrison’s interpretation contradicts the IS-LM model. The demand constraint is derived from the IS-LM model and the IS-LM demand constraint is used to illustrate Keynes’s theory.

KEYWORDS: John Maynard Keynes, Roger W. Garrison, IS-LM model, Hayekian triangle, capital-based macroeconomics, Keynesian demand constraint, socialization of investment

The Mises Institute is a non-profit organization that exists to promote teaching and research in the Austrian School of economics, individual freedom, honest history, and international peace, in the tradition of Ludwig von Mises and Murray N. Rothbard. 

Non-political, non-partisan, and non-PC, we advocate a radical shift in the intellectual climate, away from statism and toward a private property order. We believe that our foundational ideas are of permanent value, and oppose all efforts at compromise, sellout, and amalgamation of these ideas with fashionable political, cultural, and social doctrines inimical to their spirit.
