Policy rules in practice

Over the past twenty years, monetary policy rules have played an increasingly central role in disucssions of monetary policy strategy and tactics at the Federal Reserve. This represented a sea change in thinking about monetary policy in terms of a systematic startagey rather than a sequence of policy decisions.     

MILTON FRIEDMAN ON THE INEFFECTIVENESS OF FISCAL POLICY

This article examines the evolution of the views of Milton Friedman on the (lack of) effectiveness of fiscal policy as compared with monetary policy. Though his views changed, it would not be accurate to say that he began as a naïve Keynesian. The empirical evidence bears out Friedman's later views.     

The effective of China's monetary policy: Quantity versus price rules

This paper deduces an open economic DSGE model and explores two monetary policy rules for China, the quantity and price rule. The empirical results indicate that (1) monetary policy with money supply as instrument seems increasingly difficult to conduct in China than before, (2) the linkage between money supply and output becomes weaker over time, and (3) the effects of a price rule on the economy seem to have become more significant than those of a quantity rule. The findings seem to favor the government’s intention of liberalizing interest rates and making a more active use of the price instrument as the economy becomes more market-oriented in recent years.     

Optimal interest rate stabilization in a basic sticky-price model

This paper studies optimal monetary policy with the nominal interest rate as the single policy instrument. Firms set prices in a staggered way without indexation and real money balances contribute separately to households’ utility. The optimal deterministic steady state under commitment is the Friedman rule—even if the importance assigned to the utility of money is small relative to consumption and leisure. We approximate the model around the optimal steady state as the long-run policy target. Optimal monetary policy is characterized by stabilization of the nominal interest rate instead of inflation stabilization as the predominant principle.     

The importance of rules-based monetary policy in practice

This paper draws on several actual policy experiences of the author to demonstrate why it is important to have a rules-based monetary policy. These experiences show that policy rules provide a needed “steady as you go” strategy and serve as an insurance against excessive intervention. They also show why in practice one must consider rules-based policy in the broader policy context in which the Federal Reserve operates.     

On the informational role of term structure in the US monetary policy rule

This paper uses a structural approach based on the indirect inference principle to estimate a standard version of the new Keynesian monetary (NKM) model augmented with term structure using both revised and real-time data. The estimation results show that the term spread and policy inertia are both important determinants of the US estimated monetary policy rule whereas the persistence of shocks plays a small but significant role when revised and real-time data of output and inflation are both considered. More importantly, the relative importance of term spread and persistent shocks in the policy rule and the shock transmission mechanism drastically change when it is taken into account that real-time data are not well behaved.     

Note on ‘Loss of monetary discretion in a simple dynamic policy game’

Jensen (1994a) finds that loss of monetary discretion leads to lower welfare. However, by extending his model we show that if real base money holdings are relatively low, as is likely to be the case for modern economics, a zero-inflation rule may well be preferable to monetary discretion. If the emphasis on achieving the output and public spending targets falls, a zero-inflation rule is more likely to be preferred. The increased support for binding policy rules thus conforms with a less tolerant attitude towards inflation.     

Effect of monetary policy shocks on the racial unemployment rates in the US

This study analyzes the effect of monetary policy shocks on the unemployment rate of different racial groups in the US, using data from 1969Q2 to 2015Q4. Employing a narrative approach to identify monetary policy shocks and local projections, we find that although an expansionary monetary shock affects White workers positively and significantly, the effect on Black workers is larger, and for Hispanic workers it is not statistically different from zero. These results are robust when considering unconventional monetary policy measures in the specification, and when exploring the impact of monetary policy on different genders and age groups. We also highlight how recession affects the transmission channel of monetary policy to the labor market for White and Hispanic workers. Finally, further extensions suggest that the Fed’s monetary policy is effective in reducing the racial unemployment gap, particularly between Whites and Blacks, and during economic booms.     

Security markets and the information content of monetary policy turning points

Substantial evidence shows that a significant relationship exists between Federal Reserve monetary policy signals and subsequent security returns. Recent evidence, however, suggests that Fed rate changes do not signal shifts in monetary policy and therefore have no real policy significance. In this study, we investigate whether certain Fed signals, characterized as turning points in the monetary cycle, have real policy significance. Our evidence suggests that the Fed's signal that a turning point is occurring is unambiguous, predicts a substantial shift in Fed monetary policy, and provides costless and meaningful information about future security market returns.     

Monetary policy transparency in a forward-looking market: Evidence from the United States

Because unsatisfactory measures of the monetary policy transparency were used, the existing literature found mixed empirical results for the relationship between the monetary policy transparency and risk/volatility. This paper extends the literature by using a recently developed monetary transparency index [Kia’s (2011) index] which is dynamic and continuous. Furthermore, the existing literature ignores the fact that market participants can be forward looking and, therefore, not policy invariant. This study also finds that the agents in the market are not policy invariant and the more transparent the monetary policy is the less risky and volatile the money market will be.     

How does Monetary Policy Respond to Exchange Rate Movements? New International Evidence*

This article analyzes how monetary policy has responded to exchange rate movements in six open economies, paying particular attention to the two‐way interaction between monetary policy and the exchange rate. We address this issue using a structural VAR model that is identified using a combination of sign and short‐term (zero) restrictions. Doing so we find that, while there is a instantaneous reaction in the exchange rate following a monetary policy shock in all countries, monetary policy responds significantly on impact to an exchange rate shock in only four of the six countries.     

Does monetary policy influence banks’ risk weights under the internal ratings-based approach?

This paper studies the extent to which monetary policy may affect banks’ perception of credit risk and the way banks measure risk under the internal ratings-based approach. Specifically, we empirically analyze the effect of different monetary policy variables on banks’ risk weights for credit risk. We present robust evidence of a strong, statistically significant relationship between monetary policy easing and lower implicit risk weights of banks using the internal ratings-based approach. Further, we show that the recent prolonged period of accommodative monetary policy has been instrumental in establishing this relationship. The presented findings have important implications for the prudential authority, which should be aware of the possible side effects of monetary policy on how banks measure risk.     

Should the monetary policy rule be different in a financial crisis?

This article reviews the finding that standard loss functions in output and inflation are higher during discretionary periods than in periods during which monetary policy is described by a rule, such as the Taylor rule. It shows that the finding is consistent with earlier research, but argues that we really do not know if the Taylor rule would have improved performance during the recent financial crisis. The article then considers modifications of policy rules to deal with changes in interest rate spreads, credit aggregates and banks׳ balance sheets.     

Optimal interest-rate rules and inflation stabilization versus price-level stabilization

This paper compares the properties of interest-rate rules such as simple Taylor rules and rules that respond to price-level fluctuations (called Wicksellian rules) in a basic forward-looking model. By introducing appropriate history dependence in policy, Wicksellian rules perform better than optimal Taylor rules in terms of welfare, robustness to alternative shock processes, and are less prone to equilibrium indeterminacy. A simple Wicksellian rule augmented with a high degree of interest rate inertia resembles a robustly optimal rule, i.e., a monetary policy rule that implements the optimal plan and that is also completely robust to the specification of exogenous shock processes.     

通货膨胀目标制:加拿大银行的政策实践与启示

在加拿大的通货膨胀目标制政策框架下,中央银行定期向公众宣布政策通货膨胀目标,然后根据通货膨胀预测值与政策目标之间的差距来确定调控方向;在实践中,加拿大银行通过使用利率操作区间和公告操作,从而很好地实现了对市场流动性及短期利率目标的调控,进而影响到市场主体的经济决策,并最终成功实现了实际通货膨胀率稳定地波动在中央银行的目标范围内。基于此,我国有必要借鉴加拿大银行的做法,建立一个更为简单透明的政策操作框架,以保证货币政策操作的效果。     

Financial conditions and monetary policy in the US

We examine the FED’s monetary policy rule with financial stability considerations and under asymmetry. We use the National Financial Conditions Index constructed by the Chicago FED in order to test whether financial stability concerns enter monetary policy formulations in the US. We model nonlinearity in monetary policy by a Markov regime-switching model. The results show that the monetary policy implemented by the FED can be characterized as a two-state Markov process and financial instability significantly increases the likelihood of regime-switching from a “tranquil” to a “distressed” regime. Moreover, the likelihood of a switch in the FED’s monetary policy regime between tranquil and distressed seems to increase when a certain threshold level of the financial conditions index is reached. Finally, our results seem to be robust to alternative specifications of the reaction function and different forms of non-linearity.

Quasi ex-ante inflation forecast uncertainty

We propose a measure of the effects of monetary policy based on an analysis of the distribution of the ex-post inflation forecast uncertainty. We argue that the difference between the distributions of the ex-ante and ex-post uncertainties reflects the impact of monetary policy decisions. Using the theoretical background of the New Keynesian model with imperfect information and a monetary policy rule, we derive a proxy for ex-ante inflation uncertainty called quasi ex-ante forecast uncertainty, which is free to a certain extent of the effects of monetary policy decisions. Furthermore, we introduce the compound strength measure of monetary policy, as well as the uncertainty ratio, which approximates the impact of monetary policy on the reduction of the inflation forecast uncertainty. Our empirical results show that the greatest policy effect in reducing the inflation forecast uncertainty occurs for countries which conduct either a well-established or a relatively pure inflation targeting policy.     

Monetary policy and bank performance: The role of business models

This paper examines the relationship between monetary policy and bank performance in a multiple-instrument environment, particularly highlighting the conditioning role of bank business models. Employing a unique dataset of Vietnamese commercial banks from 2007 to 2019, we display that banks react to monetary policy changes, either when the central bank increases policy rates or injects money into the economy through open market operations, by decreasing overall returns and increasing financial instability. Additionally, we document that the accumulation of foreign exchange reserves benefits bank outcomes, contrasting to open market operations, albeit the central bank uses both of these policy instruments to alter money supply in the economy. Our key analysis of interest reveals that business models considerably matter in the effects of monetary policy on bank performance. Collectively, our findings demonstrate that banks’ business models that yield more non-interest income or diversify more into different income sources may mitigate the pass-through of monetary policy to bank performance. This finding holds across all interest- and quantitative-based monetary policy indicators and across all the functions of risk-taking behavior, earning-profit capacity, and financial stability. Furthermore, while plotting the marginal effects of monetary policy, we realize that they are insignificant for banks whose business models heavily rely on non-traditional segments.
