Basically Hicks said we should think of a money market where inelastic (ie - vertical) money supply meets money demand. There interest rate is on the y axis there. There's also a classic loanable funds market with the usual supply and demand curves - supply thought of as savings and investment thought of as demand. The y axis also has the interest rate here.<br /><br />So Hicks presented two markets with the same price - the interest rate.<br /><br />Now, he said, demand for loanable funds, supply of savings, and demand for money all shift as income/output increases. So he said we should trace the equilibrium points of the interest rate in each of those two markets as we change income/output. That will give you a downward sloping series of equilibrium interest rates in the loanable funds market (this is called the IS curve), and an upward sloping series of equilibrium interest rates in the money market (this is called the LM curve).<br /><br />Now, there can only be one interest rate, and that is the intersection of the IS and the LM curve. You've pinned down the interest rate with these two markets for which the interest rate is the price, and it gives you the level of output that that's consistent with that interest rate. The point is, there's nothing that constrains that level of output to be a full employment level of output. Several others - Hansen, Modigliani, Klein, etc. - expanded on this basic Hicksian model.<br /><br />Keynes was familiar with Hicks's model, but rejected it (see the link above). He did not think the interest rate cleared the loanable funds market - he only thought it cleared the money market.<br /><br /><br />Check out the New School's History of Economic thought website for more details - they have a good page on IS-LM, and they've got a strong post-Keynesian vein so I'm sure they've got a good discussion of non-Hicksian Keynesianism (which, as I alluded to, is not the form of Keynesianism I consider myself a part of).Danielhttps://www.blogger.com/profile/17192667997950934790noreply@blogger.comtag:blogger.com,1999:blog-1740670447258719504.post-90252077018802537982010-12-23T19:23:52.365-05:002010-12-23T19:23:52.365-05:00I'd be very interested in an elaboration/expla...I'd be very interested in an elaboration/explanation of this point from your conversation if you ever have the time:<br /><br />"- Keynes thought that the interest rate coordinates the supply and demand for cash/liquidity (Hicks said both the Austrians and Keynes were right - it serves both functions... I personally prefer Hicks to Keynes on this)"<br /><br />Or else if you could recommend a good place to start on this subject, I'd appreciate it a lot.Anonymousnoreply@blogger.com
