How Do Monetary Policy Surprises Affect Household Sentiment?
We examine the effect of monetary policy surprises, or unexpected changes in the federal funds rate, on household sentiment. We first assume that the effect of monetary policy surprises does not depend on the state of the economy, as is noted in the literature, and find that household sentiment is not sensitive to monetary policy surprises. We then hypothesize that the effect of monetary policy surprises changes with certain economic environments. We find that when inflation was low in the previous month, an unexpected policy rate hike significantly boosts sentiment. Contrastingly, when ...

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 ...

Rising Skill Supply, Technological Changes, and Innovation: A Quantitative Exploration of China
Can the expansion of higher education lead to firm productivity growth? In this paper, we examine how China's college expansion program contributes to the rapid growth of firms' R&D expenditure and productivity. In our model, heterogeneous firms make endogenous R&D decisions, requiring them to allocate skilled workers between production and R&D. We structurally estimate the model using firm-level data on the level and distribution of R&D, as well as macro-level data on skill prices and sectoral allocation. Quantitative analysis reveals that between 2004 and 2018, the combination of the ...

A Comment on 'Wealth Inequality and Endogenous Growth' by Byoungchan Lee
How does wealth inequality affect economic growth? Byoungchan Lee answers this question by developing a heterogeneous-agent model and augmenting it with endogenous firm innovation. The novel channel is that rising wealth concentration reduces aggregate demand, which gives firms a disincentive to spend on R&D and therefore leads to slower productivity growth. In this discussion, we first explain the difference in calibration strategy between Lee’s approach and the common approach in the literature, and then discuss its quantitative implications for the effect of rising inequality on ...

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 ...

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 ...

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 ...

Asymmetric Information, Two-Way Learning, and the Fed Information Effect
How important is the information effect of monetary policy? We first show analytically that the reduced-form method of regressing forecast revisions on monetary policy surprises leads to a biased estimation, due to the correlation between monetary policy surprises and the unobserved shocks. We then develop a New Keynesian model in which asymmetric information originates from a two-way learning mechanism: the central bank learns from lagged aggregate inflation and output, and firms learn from individual marginal costs and the interest rate. We calibrate our model parameters to match ...

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 ...

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 ...
