Conservatism and Liquidity Traps
Appointing Rogoff's (1985) conservative central banker improves welfare if the economy is subject to large contractionary shocks and the policy rate occasionally falls to the zero lower bound (ZLB). In an economy with occasionally binding ZLB constraints, the anticipation of future ZLB episodes creates a trade-off between inflation and output stabilization. As a consequence, inflation systematically falls below target even when the policy rate is above zero. A conservative central banker mitigates this deflationary bias away from the ZLB, improving allocations both at and away from the ZLB ...

The Risk of Returning to the Effective Lower Bound: An Implication for Inflation Dynamics After Lift-Off
In this note, we analyze an implication of the effective lower bound (ELB) risk--the possibility that adverse shocks will force policymakers in the future to lower the policy rate to the ELB--on inflation dynamics after liftoff.

The Risk-Adjusted Monetary Policy Rule
Macroeconomists are increasingly using nonlinear models to account for the effects of risk in the analysis of business cycles. In the monetary business cycle models widely used at central banks, an explicit recognition of risk generates a wedge between the inflation-target parameter in the monetary policy rule and the risky steady state (RSS) of inflation---the rate to which inflation will eventually converge---which can be undesirable in some practical applications. We propose a simple modification to the standard monetary policy rule to eliminate the wedge. In the proposed risk-adjusted ...

Speed Limit Policy and Liquidity Traps
The zero lower bound (ZLB) constraint on interest rates makes speed limit policies (SLPs)---policies aimed at stabilizing the output growth---less effective. Away from the ZLB, the history dependence induced by a concern for output growth stabilization improves the inflation-output tradeoff for a discretionary central bank. However, in the aftermath of a deep recession with a binding ZLB, a central bank with an objective for output growth stabilization aims to engineer a more gradual increase in output than under the standard discretionary policy. The anticipation of a more restrained ...

Effective Lower Bound Risk
Even when the policy rate is currently not constrained by its effective lower bound (ELB), the possibility that the policy rate will become constrained in the future lowers today's inflation by creating tail risk in future inflation and thus reducing expected inflation. In an empirically rich model calibrated to match key features of the U.S. economy, we find that the tail risk induced by the ELB causes inflation to undershoot the target rate of 2 percent by as much as 50 basis points at the economy's risky steady state. Our model suggests that achieving the inflation target may be more ...

Expectations-Driven Liquidity Traps: Implications for Monetary and Fiscal Policy
We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence give rise to persistent liquidity trap episodes. There is no straightforward recipe for enhancing welfare in this economy. Raising the inflation target or appointing an inflation-conservative central banker mitigates the inflation shortfall away from the lower bound but exacerbates deflationary pressures at the lower bound. Using government spending as an additional policy instrument worsens allocations at and away from the lower bound. However, appointing a policymaker who is ...

The Risky Steady State and the Interest Rate Lower Bound
Even when the policy rate is currently not constrained by its effective lower bound (ELB), the possibility that the policy rate will become constrained in the future lowers today's inflation by creating tail risk in future inflation and thus reducing expected inflation. In an empirically rich model calibrated to match key features of the U.S. economy, we find that the tail risk induced by the ELB causes inflation to undershoot the target rate of 2 percent by as much as 45 basis points at the economy's risky steady state. Our model suggests that achieving the inflation target may be more ...

Attenuating the Forward Guidance Puzzle : Implications for Optimal Monetary Policy
We examine the implications of less powerful forward guidance for optimal policy using a sticky-price model with an effective lower bound (ELB) on nominal interest rates as well as a discounted Euler equation and Phillips curve. When the private-sector agents discount future economic conditions more in making their decisions today, an announced cut in future interest rates becomes less effective in stimulating current economic activity. While the implication of such discounting for optimal policy depends on its degree, we find that, under a wide range of plausible degrees of discounting, it ...

Gradualism and Liquidity Traps
Modifying the objective function of a discretionary central bank to include an interest-rate smoothing objective increases the welfare of an economy in which large contractionary shocks occasionally force the central bank to lower the policy rate to its effective lower bound. The central bank with an interest-rate smoothing objective credibly keeps the policy rate low for longer than the central bank with the standard objective function. Through expectations, the temporary overheating of the economy associated with such a low-for-long interest rate policy mitigates the declines in inflation ...
