Introduction: Introduction
The economic conditions this paper analyzes:
Signs that the economic slowdown may finally be over
The short-term interest rates is zero
There have been large increases in the monetary base in recent years and record accumulation of “excess reserves” by banks.
Growing concern over excessive inflation on the horizon.
This describes the US in the spring of 1937,
just before a major policy mistake:
The Mistake of 1937
Introduction: Introduction What happened in 1937? One of the biggest recessions in US economic history.
What was the mistake of 1937?
We argue that it was bad communication policy.
During the recovery phase 1933-37 the administration committed to reflating the price level to pre-depression levels, often referred to as price level of 1926.
In the spring of 1937 administration officials, President Roosevelt, Federal Chairman Eccles and others warned of too much inflation, even if prices had not risen to pre-depression levels.
Our hypothesis: This was interpreted as a regime shift and had a large negative effect expectations, and through expectations on inflation and output.

Previous literature on 1937: Previous literature on 1937 Some difference with previous literature (e.g. Friedman and Schwartz (1963)), who emphasize increase in reserve requirement in 1936 and January 1937.
In this paper the money supply was irrelevant during this period because interest rates were close to zero.
Expectations about future money supply (once deflationary pressures had subsided and interest rates would be positive again), however, were crucial.
Monetary policy was extremely important during this period but for reasons that are different that the “monetarists” claim – expectation channel the key.
The increases in the reserve requirement in 1936 and 1937 were unimportant except to the extent that they were interpreted as signals about future policy.
Slide8:
At zero interest rates inflation and output are extremely sensitive to expectations about future policy.
“Bad communication”, i.e. signaling excessive tightening, can have dramatic negative effect due to vicious feedback effects at zero interest rates, especially if expectations are conditioned on a reflationary regime.
Much bigger effect of “communication policy” at zero interest rates than under regular circumstances.
Speculative conclusion: Since the effect is asymmetric a conservative approach would be to err on the side of inflation (Japan?!!). Central Conclusions of the paper

Output Collapseunder the deflationary regime: Why output collapse? Output Collapse under the deflationary regime Government targets zero inflation
Recovery and excess sensitivityunder the Reflationary Regime: Recovery and excess sensitivity under the Reflationary Regime Government targets positive inflation target with imperfect credibility
Tries to set π=4% when possible
Each period in the reflationary regime, there is probability γt that government will abandon its policy in favor a deflationary regime in all future periods
We interpret γt as varying with the public’s change in belief due to policy communication
If gamma increases, means that the public beliefs monetary policy will be tighter in the future.
Little bit tricky to solve because of non-linearity of the zero bound and the time-varying property of the probability of regime change makes the model also highly non-linear.
Sneaky simplifying assumption: Absorbing state for both processes
Can solve the system of equations backwards, starting from the absorbing state.

Asymmetric effects of inflation vs. deflationary signals: Asymmetric effects of inflation vs. deflationary signals Show in paper that sending signals of too much inflation has much smaller effect on output or inflation
Reason: Persistent deflationary expectations interact viciously with the zero bound, deflationary signals imply deflation in all states of the world in which the zero bound is binding which creates propagation that may not even converge.
One “speculative” interpretation of this finding: It is prudent to err on the side of “too much inflation” in a transition phase out of zero interest rates especially when deflationary expectations may be hard to reverse.
Main point: Extreme volatility of the model with respect to small changes in beliefs can explain the recession of 1937 without any changes in interest rates!
The Mistake of 1937: The Mistake of 1937 Series of confusing policy communications from key administration officials
Signals of future policy change which implies a strong reaction beyond static changes in interest rates would imply.
The market started to believe that the government was going to target zero inflation.
Reneging on previous announcements to increase the price level to pre-depression levels.
Where do we find evidence for this hypothesis?

Conclusions: Conclusions In an economy with maximum policy accommodation of zero interest rates
Local to credible reflationary regime, output and inflation are extremely sensitive to communications about future policy
The effect of communicating excessive tightening has much worse implications than overshooting due to interaction between the zero bound and expectations that it will be binding in the future with associated deflation.
Implications for policymakers
Need to communicate their objectives clearly and consistently?
Err on the side of more inflation?
