2. Outline Keynesian Theories Money Illusion/“Animal spirits” Keynes on Say’s Law Liquidity Trap Non-keynesian Austrian economics Austrian Business Cycle Theory Classical Classical vs. Keynes Monetarism Quantity Theory of Money Inflation and Side Effects Government Spending
3. Money Illusion and “animal spirits” *Keynes, The General Theory of Employment, Interest, and Money **Keynes, A Tract on Monetary Reform People think in nominal terms, not real terms Deflation ↓price level, ↓nominal wages, ↔real wages ↓price level, ↔nominal wages, ↑real wages ⇒ surplus Involuntary unemployment Animal spirits: “A spontaneous urge to action rather than inaction…”* Decisions are made in the short-run, “In the long run, we are all dead.”** Confidence
4. Keynes and Say’s Law Say’s Law: People produce in order to consume No general gluts What if suppliers don’t spend? Hoarding (saving without investing) ↓AD ⇒ ↑unemployment ⇒ ↓AD ⇒ · · · Recession
5. Liquidity Trap As the interest rate approaches zero, stronger liquidity preference Individuals don’t save (invest), banks don’t lend Flat LM curve Impotent monetary policy Confidence
6. Keynesian Econ If Money illusion Glut of unemployment Low interest rates Deflation Low consumer and business confidence Hoarding/Liquidity Trap Dearth of investment Then Increase national income by shifting IS curve, increasing AD Gov’t. should spend, spend, SPEND!
7. Austrian Business Cycle Theory *Rothbard, Economic Depressions: Their Cause and Cure Expansion of credit by banks A central bank is necessary for banks to expand credit “if banks were truly competitive, any expansion of credit by one bank would quickly pile up the debts of that bank in its competitors, and its competitors would quickly call upon the expanding bank for redemption in cash”*
8. A.B.C. Theory Credit expansion ⇒ Inflationary Boom Domestic prices bid up ⇒ ↑imports Gold flows out of the country as payment for imports As banks’ gold stores dwindle, panic! Fractional reserve banking Banks call in loans, ↓Money supply (deflation) Economy contracts Balance of payments reverses
9. A.B.C. Theory Interest rate artificially depressed Malinvestment Low i rate is only temporary Overinvestment in capital goods Not enough savings to buy all producers’ goods Capital is heterogeneous
10. A.B.C. Theory Gold Standard Money supply shouldn’t increase, even if the population or supply of goods increases Deflation problems Government sanctioned ↑M ≈ counterfeiting
11. Classical Economics Smallest decision making unit: the individual Homo economicus Rational Self-interested Utility maximizing Assume perfect information
12. Classical vs. Keynes Why Keynes is wrong if people are rational, self-interested and utility maximizing. Money illusion/stickiness Example: Deflation Workers resist ↓nominal wages Businesses have 2 options: Raise prices ⇒ cost-push inflation Lay off wokers Workers seek new jobs Businesses offer wages that reflect workers real worth (if no minimum wage laws, labor unions, etc.) Stickiness due to: Time lags with change in price level Contract length Labor unions
13. Keynes’ “refutation” of Say’s Law Misrepresentation of Say’s Law Say never said that depressions and unemployment are impossible Say’s Law: supply creates its own demand, so no general gluts requires flexible, self-correcting markets A temporary glut in the labor market is not a general glut Hoarding: why?
14. Puzzling Paradox Keynesian economic man: Ruled by “animal spirits” Doesn’t make decisions for the long-run Incapable of thinking in real terms But somehow responds rationally to lower interest rates by investing less of his money…?
15. Monetarist Economics Also has roots in classical economics Disagree with both Keynesians and Austrians on inflation and the business cycle Milton Friedman
16. Quantity Theory of Money Quantity theory of money: M*V=P*Q M=quantity of money in circulation V=velocity of money P=price level Q=index of the real value of final expenditures Keynes: V is inherently unstable M, V move in opposite directions Friedman: M, V move in the same direction
17. How to Avoid Inflation Inflation is always a monetary phenomenon M and P are not independent ↑M⇒↑P Since M*V=P*Q, we have ∆M+∆V=∆P+∆Q Assume velocity is stable (∆V=0) ∆P=0 if and only if ∆M=∆Q To avoid inflation, the growth rate of the money supply should be set equal to the growth rate of output
18. Inflation and Side Effects Monetarists want monetary policy that creates a stable framework Reducing inflation is not technically difficult, but there are political barriers Possible side effects of reducing inflation: Recession Unemployment
19. Stimulus In a liquidity trap: Even if the Fed increases M, banks hesitate to lend (low interest rates) Bypass the banks, give money directly to consumers Aggregate Demand boosted without increasing government spending
20. Government Spending Where does the money come from? Increased tax revenueBorrowing from the private sector Government spends money that otherwise would have been spent in the private sector Printing money Implicit tax on holders of dollar denominated assets No legislation involved
