Ec 123 Section 1 2
The Quantity Theory of Money
The quantity equation of money relates the money in circulation (M) to the price level (P) and annual output (Q).
MV PQ
V is known as the velocity of money. It is equal to the average number of times a dollar is used during the year.
The quantity equation is an accounting identity (true by definition) but what you use for M (M1 or M2) can affect V number.
Ec 123 Section 1 3
Monetarism
• Monetarist's view of money's impact on economy can be represented in the quantity equation framework
MV = PQ,
• Increases in V imply individuals and firms are less willing to hold cash. Opposite for decrease in V.
• Monetarists claim that, under normal circumstances, V is stable (or grows at predictable rate).
• Changes in V can be attributed to
– financial innovation– change in interest rates
Ec 123 Section 1 4
Monetarism
Big policy implication: If V is stable, then the only way to change nominal GDP (=PQ) is through changes in the money supply.
• In the long run, changes in M effect only the price level, P.
• BUT in the short run changes can effect both P and real income, Q, because it takes people time to adjust their decisions to changes in the money supply.

The Fed: Institutional overview
• Federal Reserve System created in 1913.
• Decentralized power structure
– 12 Districts
– New York has dominant position on FOMC
• Major responsibilities
“…to furnish an elastic currency, to afford means of rediscounting commercial paper, to establish a more effective supervision of banking in the United States, and for other purposes.”
- Federal Reserve Act, 1913
Ec 123 Section 1 6
The Fed: Monetary Policy (Pre 1933)
• Real Bills Doctrine
– 40% of assets must be GOLD
– Other assets must be “productive credit”
• Discount Window Borrowing
– At the discretion of the regional Fed
– Primary monetary policy tool
What is the motivation for these policies?
What is the cost of these policies?

Monetary policy tools available to the Fed(Pre 2008)
• Change reserve requirement ratio (hardly ever used)
• Change discount rate (sometimes)
– Short term, secured loans to banks (1 day but now can be 30 days)
– At a higher interest rate than the Fed Funds rate (lowered difference)
– Negative Stigma associated with bank usage
• Open market operations (most commonly used today)

The Fed’s experience during the 1920’s
• In response to a severe 1920 recession the Fed raised the discount rate to stem the loss of “free gold.” In the Fed’s view
– the recession was caused by international forces beyond Fed control
– recession “cleansed” the economy for vigorous expansion.
• In 1927, the Fed helped the U.K. back to a gold standard
– used open market operations to expand the money supply
– lead to higher inflation and lower interest rates
– sterling pound appreciated relative to the dollar

• Change discount rate (sometimes)
• Open market operations (most commonly used today)

U.S. Financial Crisis of 1931: Summary
• The quantity equation of money is an accounting identity linking money to the larger economy.
• Monetarism implies that careful control of the money supply is sufficient to stabilize the economy (PQ).
• Money multiplier story. Fed doesn't set the money supply, but does have a heavy influence.
• The goals and organization of the Fed are critical to the conduct of monetary policy.
• One’s understanding of how the money supply influences the economy is crucial to the evaluation of monetary policy.
