Evaluating Monetary Policy with Inflation Bands and Horizons
Inflation targeting has become the dominant way countries approach setting monetary policy goals. However, central banks differ in how they conduct that policy and how they evaluate their success in meeting a stated inflation goal. A new assessment method combines a percentage range around a target, known as an inflation tolerance band, with central banks stating how long it will take for high or low inflation to return to that range, known as a time horizon. Comparing previously projected horizons with realized horizons can be used to evaluate policy success.

Sudden Stops and COVID-19: Lessons from Mexico’s History
The COVID-19 pandemic produced a sharp contraction in capital flows in emerging markets during the spring of 2020. Such contractions are known as “sudden stops” and historically have been associated with significant downturns in a country’s economic activity. Evidence from Mexico’s financial crisis history suggests that sudden stops tend to exhibit a common pattern: the crisis lasts one to two years before a rapid but partial recovery, followed by years of protracted stagnation.

Estimating Macroeconomic Models of Financial Crises: An Endogenous Regime-Switching Approach
We estimate a workhorse DSGE model with an occasionally binding borrowing constraint. First, we propose a new specification of the occasionally binding constraint, where the transition between the unconstrained and constrained states is a stochastic function of the leverage level and the constraint multiplier. This specification maps into an endogenous regime-switching model. Second, we develop a general perturbation method for the solution of such a model. Third, we estimate the model with Bayesian methods to fit Mexico's business cycle and financial crisis history since 1981. The estimated ...

Communicating Monetary Policy Rules
Despite the ubiquity of inflation targeting, central banks communicate their frameworks in a variety of ways. No central bank explicitly expresses their conduct via a policy rule, which contrasts with models of policy. Central banks often connect theory with their practice by publishing inflation forecasts that can, in principle, implicitly convey their reaction function. We return to this central idea to show how a central bank can achieve the gains of a rule-based policy without publicly stating a specific rule. The approach requires central banks to specify an inflation target, inflation ...

Learning about Regime Change
Total factor productivity (TFP) and investment specific technology (IST) growth both exhibit regime-switching behavior, but the regime at any given time is difficult to infer. We build a rational expectations real business cycle model where the underlying TFP and IST regimes are unobserved. We then develop a general perturbation solution algorithm for a wide class of models with unobserved regime-switching. Using our method, we show that learning about regime-switching alters the responses to regime shifts and intra-regime shocks, increases asymmetries in the responses, generates forecast ...

Permanent and Transitory Effects of the 2008–09 Recession
Separating U.S. economic output into permanent and transitory components can help explain the effects of recessions and expansions. GDP growth shifted to a lower trend rate in 2000, indicating a slowdown long before the 2008–09 recession. GDP was substantially above trend before that recession; it then declined significantly and did not recover to its trend rate until 2017. The recession resulted in permanent losses to GDP. Without those permanent effects, GDP at the end of the latest expansion would have been about $380 billion or $1,460 per person higher.

Perturbation methods for Markov-switching DSGE models
This paper develops a general perturbation methodology for constructing high-order approximations to the solutions of Markov-switching DSGE models. We introduce an important and practical idea of partitioning the Markov-switching parameter space so that a steady state is well defined. With this definition, we show that the problem of finding an approximation of any order can be reduced to solving a system of quadratic equations. We propose using the theory of Grobner bases in searching all the solutions to the quadratic system. This approach allows us to obtain all the approximations and ...

Optimal Monetary Policy Regime Switches
An economy that switches between high and low growth regimes creates incentives for the monetary authority to change its rule. As lower growth tends to produce lower real interest rates, the monetary authority has an incentive to increase the inflation target and increase the degree of inertia in setting rates in an attempt to keep the nominal rate away from the zero lower bound. An optimizing monetary authority therefore responds to permanently lower growth by slightly increasing both the inflation target and inertia; focusing solely on the inflation target ignores a key margin of ...

Have Lags in Monetary Policy Transmission Shortened?
The Federal Open Market Committee’s monetary policy has expanded beyond changing the federal funds rate to include forward guidance and balance sheet policy. Using these tools may shorten lags in monetary policy transmitting to inflation. Using a proxy funds rate that incorporates tightening from these additional policy tools, we find evidence of a shorter lag in policy transmission to inflation since 2009, though with high associated uncertainty.

Monetary Policy Stance Is Tighter than Federal Funds Rate
The Federal Reserve’s use of forward guidance and balance sheet policy means that monetary policy consists of more than changing the federal funds rate target. A proxy federal funds rate that incorporates data from financial markets can help assess the broader stance of monetary policy. This proxy measure shows that, since late 2021, monetary policy has been substantially tighter than the federal funds rate indicates. Tightening financial conditions are similar to what would be expected if the funds rate had exceeded 5¼% by September 2022.
