Greenspan's Conundrum and the Fed's Ability to Affect Long‐Term Yields

In February 2005 Federal Reserve Chairman Alan Greenspan noticed that the 10‐year Treasury yields failed to increase despite a 150‐basis‐point increase in the federal funds rate and called it a “conundrum.” This paper investigates the historical relationship between the 10‐year Treasury yield and the federal funds rate and finds that the relationship changed dramatically in the late 1980s, well in advance of Greenspan's observation. The paper evaluates three competing hypotheses for the change. The evidence from a variety of sources supports the conclusion that the most plausible explanation is that the change occurred because the FOMC began using the federal funds rate as a policy instrument.     

Monetary Policy,Asset Prices,and Liquidity in Over‐the‐Counter Markets

We develop a model where agents can allocate their wealth between a liquid asset, which can be used to purchase consumption goods, and an illiquid asset, which represents a better store of value. Should a consumption opportunity arise, agents may visit a frictional “over‐the‐counter” secondary asset market where they can exchange illiquid for liquid assets. We characterize how monetary policy affects both the issue price and the secondary market price of the asset. We also show that, in contrast to conventional wisdom, search and bargaining frictions in the secondary asset market can improve welfare if inflation is low.     

Optimal Monetary Policy and Transparency under Informational Frictions

This paper examines the optimal monetary policy and central bank transparency in an economy where firms set prices under informational frictions. The economy is subject to two types of shocks determining the efficient output level and firms' desired markups. To minimize the welfare‐reducing output gap and price dispersion between firms, the central bank controls firms' incentives and expectations by using a monetary instrument and disclosing information on the realized shocks. This paper shows that an optimal policy comprises the disclosure of a linear combination of the two shocks and the adjustment of monetary instruments contingent on the disclosed information.     

U.S. Monetary Policy Surprises and Currency Futures Markets: A New Look

Intraday currency futures prices react to both surprises in the federal funds target rate (the target factor) and surprises in the anticipated future direction of Federal Reserve monetary policy (the path factor) in similar magnitude, and the reaction is short‐lived. Dollar‐denominated currency futures prices drop significantly in response to positive surprises (i.e., unexpected increases) in the target and path factors, but have generally little response to negative surprises. A monetary policy tightening during expansionary periods leads to an appreciation of the domestic currency, while a monetary policy loosening during recessionary periods tends to have no significant impact.     

Asymmetric Preferences and the Stability Problem for Optimal Monetary Policy Rules

This paper evaluates the stability properties of optimal monetary policy rules when professionals under adaptive learning have asymmetric preferences. The asymmetric preferences require volatility estimates in real time. An expectations‐based rule can stabilize the economy, while a fundamentals‐based rule leads to instability.     

Monetary News Shocks

We pursue an empirical strategy to identify a monetary news shock in the U.S. economy. We use a monetary policy residual, along with other variables in a vector autoregression (VAR), and identify a monetary news shock as the linear combination of reduced-form innovations that is orthogonal to the current residual and that maximizes the sum of contributions to its forecast error variance over a finite horizon. Real GDP declines in a persistent manner after a positive monetary news shock. This contraction in economic activity is accompanied by a fall in inflation and a rapid increase in the nominal interest rate.     

The Response of Equity Prices to Movements in Long‐Term Interest Rates Associated with Monetary Policy Statements: Before and After the Zero Lower Bound

Monetary policy actions since 2008 have influenced long‐term interest rates through forward guidance and quantitative easing. I propose a strategy to identify the comovement between interest rate and equity price movements induced by monetary policy when an observable representing policy changes is not available. A decline in long‐term interest rates induced by monetary policy statements has a larger positive effect on equity prices prior to 2009 than in the subsequent period. This change appears to reflect the impact of the zero lower bound on short‐term interest rates.     

International Transmission of U.S. Monetary Policy Shocks: Evidence from Stock Prices

This paper analyzes intraday changes in firm‐level equity prices around interest rate announcements to assess the transmission of U.S. monetary policy to the global economy. We document that foreign firms on average are roughly as sensitive to U.S. monetary policy as U.S. firms, although we also find considerable cross‐sectional variation across firms. In particular, foreign stocks in cyclically sensitive industries show stronger responses to interest rate surprises, consistent with a demand channel of policy transmission. In addition, transmission of U.S. policy appears to be stronger to economies with fixed exchange rates. Evidence for a credit channel is weaker.     

我国货币政策多重非对称效应实证检验

实证检验表明：在不同的年份,我国经济或受到正向货币供给冲击,或受到负向货币供给冲击;我国东部地区、东北地区、西部地区和中部地区并不总是同时处于地区经济周期的繁荣或衰退阶段;我国不同调控方向的货币政策对处于地区经济周期不同阶段的四地区经济的影响是不相同的,即存在货币政策多重非对称效应。     

Infrequent Housing Adjustment,Limited Participation,and Monetary Policy

This paper asks why monetary contractions have strong effects on the housing market. The paper presents a model with staggered housing adjustment in which monetary policy has real effects in the absence of any rigidity in producer pricing or wages. Limited participation in financial markets leads to a rise in the real mortgage rate following an increase in the nominal short rate. Since households must take on a mortgage to consume housing, the rise in the real interest rate reduces the share of residential investment in output.     

Liquidity and Information Flow around Monetary Policy Announcement

We analyze the effects of monetary policy announcements on stock market liquidity using intraday data. We show that the impairment in liquidity associated with policy announcements occurs primarily after, rather than before, the announcements, and is relatively short lived, lasting about 1.5 hours. Liquidity impairment varies proportionately with the information content of the policy announcement, with larger effects associated with unscheduled announcements and scheduled announcements with larger policy surprises. Overall, our results suggest that informed traders have an information processing advantage over uninformed participants rather than access to private information.     

U.S. Monetary Policy and International Bond Markets

This paper analyzes how U.S. monetary policy affects the pricing of dollar‐denominated sovereign debt. We document that yields on dollar‐denominated sovereign bonds are highly responsive to U.S. monetary policy surprises—during both the conventional and unconventional policy regimes—and that the passthrough of unconventional policy to foreign bond yields is, on balance, comparable to that of conventional policy. In addition, a conventional U.S. monetary easing (tightening) leads to a significant narrowing (widening) of credit spreads on sovereign bonds issued by countries with a speculative‐grade credit rating but has no effect on the corresponding weighted average of bilateral exchange rates for a basket of currencies from the same set of risky countries; this indicates that an unanticipated tightening of U.S. monetary policy widens credit spreads on risky sovereign debt directly through the financial channel, as opposed to indirectly through the exchange rate channel. During the unconventional policy regime, yields on both investment‐ and speculative‐grade sovereign bonds move one‐to‐one with policy‐induced fluctuations in yields on comparable U.S. Treasuries. We also examine whether the response of sovereign credit spreads to US monetary policy differs between policy easings and tightenings and find no evidence of such asymmetry.     

Monetary Policy Choices in Emerging Market Economies: The Case of High Productivity Growth

We develop a general equilibrium model of an emerging market economy where productivity growth differentials between tradable and non-tradable sectors result in an equilibrium appreciation of the real exchange rate—the so-called Balassa-Samuelson effect. The paper explores the dynamic properties of this economy and the welfare implications of alternative policy rules. We show that the real exchange rate appreciation limits the range of policy rules that, with a given probability, keep inflation and exchange rate within predetermined numerical targets. We also find that the B–S effect raises by an order of magnitude the welfare loss associated with policy rules that prescribe active exchange rate management.     

Ben Bernanke in Doha: The Effect of Monetary Policy on Optimal Tariffs

Trade liberalization can imply slow and long adjustment processes. Taking account of these adjustment processes can change the evaluation of trade policy, especially when policymakers care more about the next couple of years than the infinite future. In this paper, I analyze the setting of tariffs in a two‐country model taking account of adjustment processes with special emphasis on the effects of nominal price rigidity and monetary policy. I show that nominal price rigidity induces policymakers with a short planning horizon to set lower tariffs because it enhances the short‐run drop in consumption following an increase in tariffs. Monetary policy that aggressively fights deviations from its inflation target implies even lower optimal tariffs.     

基于ERPT效应的我国货币政策与汇率政策协调性研究

通过ARDL模型对我国名义有效汇率对物价水平的ERPT效应进行了测度,发现现阶段我国货币政策与汇率政策各自都较合乎情理,但是二者并没有达成一种相互协调的整体。在目前ERPT效应相对较低（货币政策的稳定情况影响效应的大小）和支出转换效应效果不明显的现实情况下,保证货币政策稳健、及时、有效,并对货币供给的自主控制将成为我国央行的首要目标,而适度的放开名义汇率的浮动范围将成为实现这一目标的有效途径。     

Optimal Monetary and Fiscal Policy with a Zero Bound on Nominal Interest Rates

I characterize optimal monetary and fiscal policy in a stochastic New Keynesian model when nominal interest rates may occasionally hit the zero lower bound. The benevolent policymaker controls the short‐term nominal interest rate and the level of government spending. Under discretionary policy, accounting for fiscal stabilization policy eliminates to a large extent the welfare losses associated with the presence of the zero bound. Under commitment, the gains associated with the use of the fiscal policy tool remain modest, even though fiscal stabilization policy is part of the optimal policy mix.     

A New Data Set on Monetary Policy: The Economic Forecasts of Individual Members of the FOMC

This paper describes a new data set of the forecasts of output growth, inflation, and unemployment prepared by individual members of the Federal Open Market Committee. The paper discusses the scope of the data set, possibilities for extending it, and some potential uses. It offers a preliminary examination of some of the cross‐sectional features of the data.
