Taylor rules in a limited participation model
The authors use the limited participation model of money to study Taylor rules' operating characteristics for setting the interest rate. Rules are evaluated according to their ability to protect the economy from bad outcomes like the burst of inflation observed in the 1970s. On the basis of their analysis, the authors argue for a rule that 1) raises the nominal interest rate more than one-for-one with a rise in inflation; and 2) does not change the interest rate in response to a change in output relative to trend.

The expectations trap hypothesis
The authors examine the inflation take-off of the early 1970s in terms of the expectations trap hypothesis, according to which fear of violating the public?s inflation expectations pushed the Fed into producing high inflation. This interpretation is compared with the Phillips curve hypothesis, according to which the Fed produced high inflation as the unfortunate byproduct of a conscious decision to jump-start a weak economy. Which hypothesis is more plausible has important implications for what should be done to prevent future inflation flare-ups.

Monetary policy in a financial crisis
What are the economic effects of an interest rate cut when an economy is in the midst of a financial crisis? Under what conditions will a cut stimulate output and employment, and raise welfare? Under which will it have the opposite effects? The authors answer these questions in a general class of open-economy models, modeling a financial crisis as a time when collateral constraints are suddenly binding. They find that when there are frictions in adjusting the level of output in the traded goods sector and the rate at which that output can be used in other parts of the economy, a cut in the ...

The Adjustment of Global External Balances: Does Partial Exchange Rate Pass-Through to Trade Prices Matter?
This paper assesses whether partial exchange rate pass-through to trade prices has important implications for the prospective adjustment of global external imbalances. To address this question, we develop and estimate an open-economy DGE model in which pass-through is incomplete due to the presence of local currency pricing, distribution services, and a variable demand elasticity that leads to fluctuations in optimal markups. We find that the overall magnitude of trade adjustment is similar in a low and high pass-through world with more adjustment in a low pass-through world occurring through ...

Entry dynamics and the decline in exchange-rate pass-through
The degree of exchange-rate pass-through to import prices is low. An average passthrough estimate for the 1980s would be roughly 50 percent for the United States implying that, following a 10 percent depreciation of the dollar, a foreign exporter selling to the U.S. market would raise its price in the United States by 5 percent. Moreover, substantial evidence indicates that the degree of pass-through has since declined to about 30 percent. ; Gust, Leduc, and Vigfusson (2010) demonstrate that, in the presence of pricing complementarity, trade integration spurred by lower costs for importers ...

Inflation Uncertainty and Endogenous Planning Horizons
We develop a finite-horizon planning model in which firms choose how far ahead to plan when setting prices. Planning further ahead improves a firm's pricing decision but requires cognitive effort. We derive analytical solutions for a firm's chosen planning horizon and show that large and persistent aggregate demand or supply disturbances induce firms to plan further ahead, making inflation more sensitive to shocks and generating endogenous movements in inflation uncertainty. Quantitatively, we show that the model matches the positive relationship between the size of inflation forecast ...

Forward Guidance with Bayesian Learning and Estimation
Considerable attention has been devoted to evaluating the macroeconomic effectiveness of the Federal Reserve's communications about future policy rates (forward guidance) in light of the U.S. economy's long spell at the zero lower bound (ZLB). In this paper, we study whether forward guidance represented a shift in the systematic description of monetary policy by estimating a New Keynesian model using Bayesian techniques. In doing so, we take into account the uncertainty that agents have about policy regimes using an incomplete information setup in which they update their beliefs using Bayes ...

Monetary Policy, Incomplete Information, and the Zero Lower Bound
In the context of a stylized New Keynesian model, we explore the interaction between imperfect knowledge about the state of the economy and the zero lower bound. We show that optimal policy under discretion near the zero lower bound responds to signals about an increase in the equilibrium real interest rate by less than it would when far from the zero lower bound. In addition, we show that Taylor-type rules that either include a time-varying intercept that moves with perceived changes in the equilibrium real rate or that respond aggressively to deviations of inflation and output from their ...

The Empirical Implications of the Interest-Rate Lower Bound
Using Bayesian methods, we estimate a nonlinear DSGE model in which the interest-rate lower bound is occasionally binding. We quantify the size and nature of disturbances that pushed the U.S. economy to the lower bound in late 2008 as well as the contribution of the lower bound constraint to the resulting economic slump. We find that the interest-rate lower bound was a significant constraint on monetary policy that exacerbated the recession and inhibited the recovery, as our mean estimates imply that the zero lower bound (ZLB) accounted for about 30 percent of the sharp contraction in U.S. ...

Short-term Planning, Monetary Policy, and Macroeconomic Persistence
This paper uses aggregate data to estimate and evaluate a behavioral New Keynesian (NK) model in which households and firms plan over a finite horizon. The finite-horizon (FH) model outperforms rational expectations versions of the NK model commonly used in empirical applications as well as other behavioral NK models. The better fit of the FH model reflects that it can induce slow-moving trends in key endogenous variables which deliver substantial persistence in output and inflation dynamics. In the FH model, households and firms are forward-looking in thinking about events over their ...
