Macroeconomic Dynamics Near the ZLB : A Tale of Two Countries

We compute a sunspot equilibrium in an estimated small-scale New Keynesian model with a zero lower bound (ZLB) constraint on nominal interest rates and a full set of stochastic fundamental shocks. In this equilibrium a sunspot shock can move the economy from a regime in which inflation is close to the central bank's target to a regime in which the central bank misses its target, inflation rates are negative, and interest rates are close to zero with high probability. A nonlinear filter is used to examine whether the U.S. in the aftermath of the Great Recession and Japan in the late 1990s ...

How to escape a liquidity trap with interest rate rules

I study how central banks should communicate monetary policy in liquidity trap scenarios in which the zero lower bound on nominal interest rates is binding. Using a standard New Keynesian model, I argue that the key to anchoring expectations and preventing self-fulfilling deflationary spirals is to promise to keep nominal interest rates pegged at zero for a length of time that depends on the state of the economy. I derive necessary and sufficient conditions for this type of state-contingent forward guidance to implement the welfare-maximizing equilibrium as a globally determinate (that is, ...

Working Paper
Understanding Persistent ZLB: Theory and Assessment

We develop a theoretical framework that rationalizes two hypotheses of long-lasting low interest rate episodes: deflationary-expectations-traps and secular stagnation in a unified setting. These hypotheses differ in the sign of the theoretical correlation between inflation and output growth that they imply. Using the data from Japan over 1998:Q1-2019:Q4, we find that the data favor the expectations-trap hypothesis. The superior model fit of the expectations trap relies on its ability to generate the observed negative correlation between inflation and output growth.

Piecewise-Linear Approximations and Filtering for DSGE Models with Occasionally Binding Constraints

We develop an algorithm to construct approximate decision rules that are piecewise-linear and continuous for DSGE models with an occasionally binding constraint. The functional form of the decision rules allows us to derive a conditionally optimal particle filter (COPF) for the evaluation of the likelihood function that exploits the structure of the solution. We document the accuracy of the likelihood approximation and embed it into a particle Markov chain Monte Carlo algorithm to conduct Bayesian estimation. Compared with a standard bootstrap particle filter, the COPF significantly reduces ...

The Countercyclical Benefits of Regulatory Costs

Legal academics, journalists, and senior executive branch officials alike have assumed that the cost of imposing new regulatory requirements is higher in severe recessions that drive the central bank’s policy rate to zero than in other times. This is not correct; the aggregate output costs of regulatory requirements decrease, not increase, in such recessions. This article is the first to analyze how this effect arises, drawing on both conventional macroeconomic models and empirical findings from the econometrics literature. Scholars and policymakers have likely missed the countercyclical ...
