Firm Dynamics and SOE Transformation During China’s Economic Reform
We study the reform of China’s state-owned enterprises (SOE) with a focus on the corporatization of SOEs. We first document the empirical patterns of the "grasp the large and let go of the small" policy. To quantify the implications of the reform for aggregate output and TFP, we build a three-sector firm dynamics model featuring financial frictions and endogenous firm-type choices. Our calibrated model shows that the SOE reform can increase long-run TFP by encouraging the exit of the least efficient firms in the state sector, but the magnitude of TFP growth also depends on the efficiency in ...

Firm Dynamics and SOE Transformation During China's Economic Reform
We study China’s state-owned enterprises (SOE) reform with a focus on the corporatization of SOEs. We first empirically document that small SOEs are more likely to exit or become privatized, whereas big SOEs are more likely to be corporatized while remaining under state ownership. We then build a heterogeneous-firm model featuring financial frictions, endogenous entry and exit, and optimal firm-type choices. Our calibrated model suggests that in the long run, the SOE reform increases the aggregate output by facilitating resource reallocation to the private sector. Along the transition, the ...

Forward Guidance under Imperfect Information: Instrument Based or State Contingent?
I study the optimal type of forward guidance in a flexible-price economy in which both the private sector and the central bank are subject to imperfect information about the aggregate state of the economy. In this case, forward guidance changes the private sector?s expectations about both future monetary policy and the state of the economy. I study two types of forward guidance. The first type is instrument based, in which case the central bank commits to a value of the policy instrument. The second type is state contingent, in which case the central bank reveals its imperfect information and ...

The Information Effect of Monetary Policy: Self-Defeating or Optimal?
As the Federal Reserve has become more transparent about its decisions on the federal funds target rate, the general public has begun to regard the rate as not only a benchmark interest rate, but also as a signal about the state of the economy. However, the specific information considered by the public to be revealed is not clearly understood. We investigate this question and find that the information revealed by monetary policy decisions is regarding future output growth, not inflation, and that such an information effect is theoretically optimal and does not make interest-rate policies ...

Average Inflation Targeting in a Low-Rate Environment
One significant change in the US economy in the last 20 years is the trend decline in real interest rates that pushes the policy rate near the effective lower bound (ELB) and puts downward pressure on inflation. This environment leaves conventional monetary policy tools less effective in accommodating adverse shocks. To better achieve the Federal Reserve’s dual mandate at the ELB, the FOMC adopted a new framework called average inflation targeting (AIT). In this Commentary, I demonstrate that AIT is a better policy in a low-rate environment because of its ability to anchor inflation ...

Forward Guidance during the Pandemic: Has It Changed the Public’s Expectations?
In responding to the COVID-19 crisis, the Federal Reserve has both lowered the federal funds rate and provided forward guidance. We study whether the forward guidance given with the April and June 2020 FOMC meetings altered the public’s expectations of future policy rates, GDP growth, and inflation. We find that forward guidance was effective in altering the public’s expectations about future policy rates if it was accompanied by an SEP but not expectations about economic fundamentals. We suggest that the difference might be explained by FOMC statements being interpretable in two ...

Average Inflation Targeting: Time Inconsistency And Intentional Ambiguity
We study the implications of the Fed's new policy framework of average inflation targeting (AIT) and its ambiguous communication. We show that AIT improves the trade-off between inflation and real activity by tilting the Phillips curve in a favorable way. To fully utilize this feature and maximize social welfare, the central bank has the incentive to deviate from AIT and implement inflation targeting ex post. Next, we rationalize the central bank's ambiguous communication about the horizon over which it averages inflation. Ambiguous communication, together with uncertainty about economic ...

Financial Markets’ Perceptions of the FOMC’s Data-Dependent Monetary Policy
Over the past ten years, the Federal Open Market Committee (FOMC) has repeatedly emphasized that future policy is data dependent. In this Economic Commentary, we investigate how financial markets expected future interest rates to change with the release of new data on inflation and labor market conditions. We find that the surprises in economic indicators have a stronger effect on the 2-year Treasury yield than on the expected federal funds rate to be set in the next FOMC meeting. This implies that markets understand that under the data-dependent approach, policy decisions do not heavily rely ...

How Important Is the Information Effect of Monetary Policy?
Is the "information effect" of monetary policy quantitatively important? We first use a simple model to show that under asymmetric information, monetary policy surprises are correlated with the unobserved state of the economy. This correlation implies that monetary policy surprises provide information about the state of the economy, and at the same time, explains why the estimation of the information effect may be biased. We then develop a New Keynesian DSGE model under asymmetric information and calibrate model parameters to match macroeconomic dynamics in the US and forecasting accuracy in ...

The Informational Effect of Monetary Policy and the Case for Policy Commitment
I study how the informational effect of monetary policy changes the optimal conduct of monetary policy. In my model, the private sector extracts information about unobserved shocks from the central bank's interest rate decisions. The central bank optimally changes the informational effect of the interest rate by committing to a state-contingent policy rule, in which case the Phillips curve becomes endogenous to the central bank's optimization problem. In a dynamic model, the optimal policy rule overshoots the natural-rate shock and gradually responds to the cost-push shock, which makes the ...
