LECTURE 7 Monetary Factors in the
Great Depression

Early Federal Reserve
• Still learning its job.
• Initially NY Fed was dominant.
• Famous head, Benjamin Strong, died in October 1928.
• Starting in 1929, conflict between NY Fed, Board of Governors, and other FR banks.
• Friedman and Schwartz argue Fed was dysfunctional in early 1930s.
Gold Standard
• System of fixed exchange rates.
• Price-specie flow mechanism: if prices fall in one country, gold (specie) will flow to that country leading to growth and inflation.
• Gold standard under pressure in 1920s. Many countries are low on gold reserves.
• U.S. unwilling to play managerial role.
Stock prices begin to rise rapidly in 1927 and 1928.

Which framework to use – IS-MP or IS-LM?
• IS-LM because the Fed in the 1920s was closer to a money targeter than to following an interest rate rule.
Nominal interest rates rose in 1928 and early 1929.

International Repercussions
• Other countries have to tighten along with the U.S. to prevent gold outflows.
• Effect is important, but not huge.

Real versus Nominal Interest Rates
i ≡ r + πe
• i is the nominal rate
• r is the real rate
• πe is expected inflation
r ≡ i - πe
How could we measure expectations of inflation?
• Newspapers or popular accounts.
• Use evidence from futures markets.
• Forecast inflation using data available at the time (lagged inflation, perhaps the money stock, etc.).
There was a large fall in expected inflation in 1930 and 1931.
Source: Stephen Cecchetti, American Economic Review, March 1992.
Narrative Evidence from Business Week
• Expected deflation after mid-1930.
• Monetary developments and Fed policy were a key source of expectations of deflation.
• “Our idle gold hoard piles up without increasing the means of payment by credit expansion because of paralysis of banking policy, thus prolonging price deflation” (4/29/31, cover).

Effect of a Fall in Expected Inflation in IS-LM
• A fall in πe shifts the LM curve (in terms of r and Y) up.
• The LM curve shifts up by the fall in πe (π0𝑒 – π1𝑒).

What happens to i when there is a fall in expected inflation?
• i = r + πe
• r rises, which tends to increase i.
• πe falls, which tends to decrease i.
• r rises by less than πe falls, so i falls.
• A fall in expected inflation (to expected deflation) can help explain why real rates rose and nominal rates fell in the early 1930s.
Why didn’t the Federal Reserve do more to stop the panics?
• Power struggle/ power vacuum within the Federal Reserve System.
• Bad model of the economy.
• Gold standard.
Was the gold standard a constraint on Federal Reserve action?
• Eichengreen says Fed couldn’t expand M to deal with panics because it would call into question the U.S. commitment to the gold standard. Gold would flow out.
• Friedman and Schwartz disagree. U.S. had huge gold reserves.
Federal Reserve engaged in monetary expansion during the Open Market Purchase Program in the spring of 1932.

Expectations of devaluation actually fell following the Open Market Purchase Program.

October 1931
• One of Friedman and Schwartz’s crucial episodes.
• Britain went off the gold standard in September 1931.
• Federal Reserve raised the discount rate 200 basis points to stem gold outflow.
• Pretty clearly another contractionary monetary shock.
