Working Paper
Monetary policy, the tax code, and the real effects of energy shocks
This paper develops a monetary model with taxes to account for the apparently asymmetric and time-varying effects of energy shocks on output and hours worked in post-World War II U.S. data. In our model, the real effects of an energy shock are amplified when the monetary authority responds to that shock by changing its inflation objective. Specifically, higher inflation raises households? nominal capital gains taxes since those taxes are not indexed to inflation. The increase in taxes behaves as a negative wealth effect and generates an immediate decline in output, investment, and hours ...

MZM: a monetary aggregate for the 1990s?
A presentation of some tentative evidence that MZM, an alternative money measure comprising all instruments payable at par on demand, has exhibited a fairly stable relationship with nominal GDP and with its own opportunity cost in recent years, suggesting a potential role for policy.

Global dynamics at the zero lower bound
This article presents global solutions to standard New Keynesian models to show how economic dynamics change when the nominal interest rate is constrained at its zero lower bound (ZLB). We focus on the canonical New Keynesian model without capital, but we also study the model with capital, with and without investment adjustment costs. Our solution method emphasizes accuracy to capture the expectational effects of hitting the ZLB and returning to a positive interest rate. We find that the response to a technology shock has perverse consequences when the ZLB binds, even when a discount factor ...

U.S. monetary policy: a view from macro theory
We use a dynamic stochastic general equilibrium model to address two questions about U.S. monetary policy: 1) Can monetary policy elevate output when it is below potential? and 2) Is the zero lower bound a trap? The model answer to the first question is yes it can, but the effect is only temporary and probably not welfare enhancing. The answer to the second question is more complicated becasue it depends on policy. It also depends on whether it is the inflation rate or the real interest rate that will adjust over the longer run if the policy rate is held near zero for an extended period. We ...

Inflation risk and optimal monetary policy
This paper shows that the optimal monetary policies recommended by New Keynesian models still imply a large amount of inflation risk. We calculate the term structure of inflation uncertainty in New Keynesian models when the monetary authority adopts the optimal policy. When the monetary policy rules are modified to include some weight on a price path, the economy achieves equilibria with substantially lower long-run inflation risk. With either sticky prices or sticky wages, a price path target reduces the variance of inflation by an order of magnitude more than it increases the variability of ...
Journal Article
The monetary instrument matters
This paper revisits the debate over the money supply versus the interest rate as the instrument of monetary policy. Using a dynamic stochastic general equilibrium framework, the authors examine the effects of alternative monetary policy rules on inflation persistence, the information content of monetary data, and real variables. They show that inflation persistence and the variability of inflation relative to money growth depend on whether the central bank follows a money growth rule or an interest rate rule. With a money growth rule, inflation is not persistent and the price level is much ...

Monetary policy and natural disasters in a DSGE model: how should the Fed have responded to Hurricane Katrina?
In the immediate aftermath of Hurricane Katrina, speculation arose that the Federal Reserve might respond by easing monetary policy. This paper uses a dynamic stochastic general equilibrium (DSGE) model to investigate the appropriate monetary policy response to a natural disaster. We show that the standard Taylor (1993) rule response in models with and without nominal rigidities is to increase the nominal interest rate. That finding is unchanged when we consider the optimal policy response to a disaster. A nominal interest rate increase following a disaster mitigates both temporary inflation ...

Taylor-type rules and total factor productivity
This paper examines the impact of a persistent shock to the growth rate of total factor productivity in a New Keynesian model in which the central bank does not observe the shock. The authors then investigate the performance of alternative policy rules in such an incomplete information environment. While some rules perform better than others, the authors demonstrate that inflation is more stable after a persistent productivity shock when monetary policy targets the output growth rate (not the output gap) or the price-level path (not the inflation rate). Both the output growth and price-level ...

Results of a study of the stability of cointegrating relations comprised of broad monetary aggregates
There is strong evidence of a stable ?money demand? relationship for MZM and M2 through the 1990s. Though the M2 relationship breaks down somewhere around 1990, evidence has been accumulating that the disturbance is well characterized as a permanent upward shift in M2 velocity that began around 1990 and was largely over by 1994. This paper?s results support the hypothesis that households permanently reallocated a portion of their wealth from time deposits to mutual funds. This reallocation may have been induced by depository restructuring, but it could also be explained by appropriately ...
