Liquidity preference

The concept was first developed by John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) to explain determination of the interest rate by the supply and demand for money.

In Man, Economy, and State (1962), Murray Rothbard argues that the liquidity preference theory of interest suffers from a fallacy of mutual determination.

In practice, however, Keynes treats the rate of interest as determining liquidity preference.

Rothbard states "The Keynesians therefore treat the rate of interest, not as they believe they do—as determined by liquidity preference—but rather as some sort of mysterious and unexplained force imposing itself on the other elements of the economic system.

"[3] Criticism emanates also from post-Keynesian economists, such as circuitist Alain Parguez, professor of economics, University of Besançon, who "reject[s] the keynesian liquidity preference theory ... but only because it lacks sensible empirical foundations in a true monetary economy".
