Abstract
In an economy with an occasionally binding zero lower bound (ZLB) constraint, the anticipation of future ZLB episodes creates a trade-off for discretionary central banks between inflation and output stabilization. As a consequence, inflation systematically falls below target even when the policy rate is above zero. Appointing Rogoff

Abstract
Even when the policy rate is not at the effective lower bound (ELB), the possibility that the policy rate will become constrained by the ELB in the future lowers today

Abstract
Modifying the objective function of a discretionary central bank to include an interest-rate smoothing objective increases the welfare of an economy where 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 does. Through expectations, the temporary overheating of the economy associated with such low-for-long interest rate policy mitigates the declines in inflation and output when the lower bound constraint is binding. In a calibrated model, we find that the introduction of an interest-rate smoothing objective can reduce the welfare costs associated with the lower bound constraint by more than half.

Abstract
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 policy rule, the intercept of the rule is modified so that the RSS of inflation equals the inflation-target parameter in the policy rule.

Abstract
The zero lower bound (ZLB) constraint on interest rates makes speed limit policies (SLPs) — policies aimed at stabilizing 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 recovery exacerbates the declines in inflation and output when the lower bound is binding.

Abstract
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 is optimal for the central bank to compensate for the reduced effect of a future rate cut by keeping the policy rate at the ELB for longer.

Abstract
We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents’ confidence can give rise to persistent liquidity trap episodes. Unlike in the case of fundamental-driven liquidity traps, there is no straightforward recipe for mitigating the welfare costs and the systematic inflation shortfall associated with expectations-driven liquidity traps. Raising the inflation target or appointing an inflation-conservative central banker improves inflation outcomes away from the lower bound but exacerbates the shortfall at the lower bound. Using government spending as an additional policy tool worsens stabilization outcomes both at and away from the lower bound. However, appointing a policymaker who is sufficiently less concerned with government spending stabilization than society can eliminate expectations-driven liquidity traps altogether.

Abstract
Assigning a discretionary central bank a mandate to stabilize an average inflation rate—rather than a period-by-period inflation rate—increases welfare in a New Keynesian model with an occasionally binding lower bound on nominal interest rates. Under rational expectations, the welfare-maximizing averaging window is infinitely long, which means that optimal average inflation targeting (AIT) is equivalent to price level targeting (PLT). However, AIT with a finite, but sufficiently long, averaging window can attain most of the welfare gain from PLT. Under boundedly-rational expectations, if cognitive limitations are sufficiently strong, the optimal averaging window is finite, and the welfare gain of adopting AIT can be small.
