Sticky Information Versus Sticky Prices Revisited: A Bayesian VAR-GMM Approach
Several Phillips curves based on sticky information and sticky prices are estimated and compared using Bayesian VAR-GMM. This method derives expectations in each Phillips curve from a VAR and estimates the Phillips curve parameters and the VAR coefficients simultaneously. Quasi-marginal likelihood-based model comparison selects a dual stickiness Phillips curve in which, each period, some prices remain unchanged, consistent with micro evidence. Moreover, sticky information is a more plausible source of inflation inertia in the Phillips curve than other sources proposed in previous studies. ...

Monetary policy, trend inflation, and the Great Moderation: an alternative interpretation: comment based on system estimation
What caused the U.S. economy's shift from the Great Inflation era to the Great Moderation era? {{p}} A large literature shows that the shift was achieved by the change in monetary policy from a passive to an active response to inflation. However, Coibion and Gorodnichenko (2011) attribute the shift to a fall in trend inflation along with the policy change, based on a solely estimated Taylor rule and a calibrated staggered-price model. We estimate the Taylor rule and the staggered-price model jointly and demonstrate that the change in monetary policy responses to inflation and other variables ...

Learning about monetary policy rules when labor market search and matching frictions matter
This paper examines implications of incorporating labor market search and matching frictions into a sticky price model for determinacy and E-stability of rational expectations equilibrium (REE) under interest rate policy. When labor adjustment takes place solely at the extensive margin, forecast-based policy that meets the Taylor principle is likely to induce indeterminacy and E-instability, regardless of whether it is strictly or flexibly inflation targeting. When labor adjustment takes place at both the extensive and intensive margins, the strictly inflation-forecast targeting policy ...

Price Dispersion and Inflation Persistence
Persistent responses of inflation to monetary policy shocks have been difficult to explain by existing models of the monetary transmission mechanism without embedding controversial intrinsic inertia of inflation. Our paper addresses this issue using a staggered price model with trend inflation, a smoothed-off kink in demand curves, and a fixed cost of production. In this model, inflation exhibits a persistent response to a policy shock even in the absence of its intrinsic inertia, because the kink causes a measure of price dispersion, which is intrinsically inertial, to become a key source of ...

A Theory of Intrinsic Inflation Persistence
We propose a novel theory of intrinsic inflation persistence by introducing trend inflation and variable elasticity of demand in a model with staggered price and wage setting. Under nonzero trend inflation, the variable elasticity generates intrinsic persistence in inflation through a measure of price dispersion stemming from staggered price setting. It also introduces intrinsic persistence in wage inflation under staggered wage setting, which affects price inflation. With the theory we show that inflation exhibits a persistent, hump-shaped response to a monetary policy shock. We also show ...

Labor Supply Shocks, Labor Force Entry, and Monetary Policy
Should monetary policy offset the effects of labor supply shocks on inflation and the output gap? Canonical New Keynesian models answer yes. Motivated by weak labor force participation during the pandemic, we reexamine the question by introducing labor force entry and exit in an otherwise canonical model with sticky prices and wages. The entry decision generates an employment channel of monetary policy, and a labor supply shock to the value of nonparticipation in the labor market induces a policy trade-off between stabilization of the employment gap and wage growth. For an adverse labor ...

Labor market search and interest rate policy
We investigate implications of search and matching frictions in the labor market for in ation targeting interest rate policy in terms of equilibrium stability. When the interest rate is set in response to past or present in ation, determinacy of equilibrium is ensured similarly to comparable previous studies with frictionless labor markets. In stark contrast to these studies, indeterminacy is very likely if the interest rate is adjusted in response solely to expected future in ation. This is due to a vacancy channel of monetary policy that stems from the labor market frictions and renders in ...

Monetary Policy and Macroeconomic Stability Revisited
A large literature with canonical New Keynesian models has established that the Fed's policy change from a passive to an active response to inflation led to U.S. macroeconomic stability after the Great Inflation of the 1970s. We revisit this view by estimating a staggered price model with trend inflation using a Bayesian method that allows for equilibrium indeterminacy and adopts a sequential Monte Carlo algorithm. {{p}} The model empirically outperforms a canonical New Keynesian model and demonstrates an active response to inflation even in the Great Inflation era, during which the U.S. ...

Inflation Gap Persistence, Indeterminacy, and Monetary Policy
Empirical studies have documented that the persistence of the gap between inflation and its trend declined after the Volcker disinflation. Previous research into the source of the decline has offered competing views while sidestepping the possibility of equilibrium indeterminacy. This paper examines the source by estimating a medium-scale DSGE model using a Bayesian method that allows for indeterminacy. The estimated model shows that the Fed's change from a passive to an active policy response to the inflation gap or a decrease in firms' probability of price change can fully account for the ...

How Should Monetary Policy Respond to a Contraction in Labor Supply?
Conventional wisdom holds that a central bank should tighten monetary policy after a surprise decline in labor supply to offset the inflationary effects of the decline. However, this policy prescription comes from models of monetary policy that abstract from labor force participation. We examine the policy implications of worker entry into and exit from the labor force. We find that cyclical changes in labor force participation call for a less restrictive policy response to a decline in labor supply. The less restrictive policy response is appropriate because policy tightening reduces the ...
