Asymmetric monetary policy rules for the euro area and the US

We analyse the implications of asymmetric monetary policy rules by estimating Markov-switching DSGE models for the euro area (EA) and the US. The estimations show that until mid-2014 the ECB’s response to inflation was more forceful when inflation was above than below the central bank’s aim. Since then, the ECB’s policy can be characterised as symmetric, and we quantify the macroeconomic implications of this policy change. We uncover asymmetries also in the Fed’s policy, which has responded more strongly in times of crisis. We compute optimal simple rules for the EA and the US in an environment with the effective lower bound and a low neutral real rate, and find that it prescribes a stronger response to inflation and the output gap when inflation is below target compared to when it is above target. We document its stabilisation properties had this optimal rule been implemented over the last two decades.     

Using Taylor Rules to Understand European Central Bank Monetary Policy

Abstract. Over the last decade, the simple instrument policy rule developed by Taylor has become a popular tool for evaluating the monetary policy of central banks. As an extensive empirical analysis of the European Central Bank's (ECB) past behaviour still seems to be in its infancy, we estimate several instrument policy reaction functions for the ECB to shed some light on actual monetary policy in the euro area under the presidency of Wim Duisenberg and answer questions like whether the ECB has actually followed a stabilizing or a destabilizing rule so far. Looking at contemporaneous Taylor rules, the evidence presented suggests that the ECB is accommodating changes in inflation and hence follows a destabilizing policy. However, this impression seems to be largely due to the lack of a forward-looking perspective in such specifications. Either assuming rational expectations and using a forward-looking specification, or using expectations as derived from surveys result in Taylor rules that do imply a stabilizing role of the ECB. The use of real-time industrial production data does not seem to play such a significant role as in the case of the United States.     

What is on the ECB’s mind? Monetary policy before and after the global financial crisis

This paper analyzes the monetary policy of the European Central Bank (ECB) both before and after the outbreak of the global financial crisis in 2008. In the literature, researchers typically select one Taylor rule-based model to analyze monetary policy of central banks and to derive determinants for the interest rate setting. However, uncertainty about the choice of this respective model is typically neglected. In contrast, we apply a Bayesian model averaging (BMA) approach to extend the Taylor rule to account for model uncertainty driven by heterogeneity in the ECB’s decision-making body, the Governing Council. Our results suggest the following: First, the ECB focuses on the inflation rate when setting interest rates. Second, economic activity indicators were in the focus of the ECB before the financial crisis. Third, over the last decade, the role of economic activity decreased, indicating that inflation is the main driver of monetary policy decisions in the post-crisis period. Fourth, when setting interest rates, central bankers appear to consider more than one model.     

Bernanke versus Taylor: a post mortem

Our analysis sheds light on the issue of whether the monetary policy contributed to the recent housing boom and bust. We have estimated and analysed a model that allows a comparison between the actual policy and several alternative Taylor rules. When the Taylor rule path was computed using revised data and the deflator for the GDP, we found a notable impact on key housing market variables, supporting Taylor’s critique of the Fed policy. However, the bulk of our evidence suggests that the policy as it would have been conducted under our real-time Taylor rules would not have had any significant impact on the housing market variables. This conclusion is robust with regard to the price index used as well as the relative weights used on the inflation and output gaps.     

TALKING LESS AND MOVING THE MARKET MORE: EVIDENCE FROM THE ECB AND THE FED

This paper examines and compares the communication strategies of the Federal Reserve and the European Central Bank, and their effectiveness. First, we find that the surprise components of both monetary policy actions and statements have important but differing effects on asset prices, with unexpected communication having a much greater impact on longer‐term interest rates. Second, both the ECB and the Fed have proven to be equally successful in moving their domestic asset prices using either monetary policy or news shocks. However, the response of the American yield curve to the surprise component of Fed's statements is larger than the reaction of the European term structure to ECB's announcements. This result is intimately related to the amplitude of the policy rate cycle that is much larger in the US than in the euro area combined with the bounded support of the news shock. Third, we analyze the cross‐effects and show that the Fed has been more able to move the European interest rates of all maturities than the ECB to move American rates. This finding is tied to the predominance of dollar fixed income assets rather than to an attempt of the ECB to mimic the Fed.     

Federal reserve monetary policy and the non-linearity of the Taylor rule

We propose and estimate a generalized Taylor rule for the monetary policy of the US Federal Reserve (Fed) to find out how the Fed funds rate is sensitive to changes in inflation and output gap variables in the post war period. We find that Fed's monetary policy has only reacted significantly to changes in inflation when they were between approximately 6.5–8.5%. However, the policy stance change on these changes was relatively small. The findings suggest that the US Fed has been too averse to change from its current monetary policy stance, and that it has not reacted noticeably to changes in the US economic activity, as measured by the output gap. The generalized functional form for the monetary policy rule suggests that similar non-linearity exists in the directional change of the Fed rate.     

Output gaps and monetary policy in the EMU area

Several considerations suggest that the ECB may respond to EMU-wide output gaps in setting policy: estimated reaction functions indicate that central banks respond to output gaps; a Taylor rule in which the central bank responds to inflation and the gap accounts for recent movements in interest rates in the EMU-area; and optimal control exercises conducted in estimated econometric models suggest that reacting to the gap may be optimal, even if the central bank cares solely about inflation. In this paper, we obtain point estimates with associated confidence bands of the EMU-wide output gap using UC models.     

An evaluation of ECB policy in the Euro's big four

The Taylor curve can be viewed as an efficiency frontier displaying the trade-off between the volatility of output and volatility of inflation. We build on the existing literature in this area and view Taylor curves as a lens through which to gauge the deviations of actual ECB policy from the optimum. We employ data over the period 1999-2013 period to measure the orthogonal distance of the observed volatilities from the Taylor curve in Germany, France, Italy, Spain, and the Euro area using a recursive VARs. We find that the distance has substantially increased in all four countries suggesting that monetary policy has become less efficacious for Germany, France, Italy, and Spain since the financial crisis in 2007-2008. We also estimate counterfactual Taylor rules and find that a simple Taylor rule would have only substantially improved monetary policy efficacy in Germany.     

Are monetary-policy reaction functions asymmetric?: The role of nonlinearity in the Phillips curve

This paper investigates the implications of a nonlinear Phillips curve for the derivation of optimal monetary policy rules. Combined with a quadratic loss function, the optimal policy is also nonlinear, with the policy-maker increasing interest rates by a larger amount when inflation or output are above target than the amount it will reduce them when they are below target. Specifically, the main prediction of our model is that such a source of nonlinearity leads to the inclusion of the interaction between expected inflation and the output gap in an otherwise linear Taylor rule. We find empirical support for this type of asymmetries in the interest rate-setting behaviour of four European central banks but none for the US Fed.     

Volatility spillovers to the emerging financial markets during taper talk and actual tapering

On 22 May 2013, Fed chairman, Ben Bernanke surprised markets by indicating to the media that the US Fed may taper its quantitative easing programme. This set out financial volatility across the globe over the next several months that spilled over to the financial markets of emerging market economies (EMEs). It prompted many EME central banks to take varied policy actions. Looking into this widely known event, this article presents formal empirical evidence establishing that (i) conditional volatility during taper talk exceeded that during actual tapering and (ii) volatility spillovers took place ‘contemporaneously’ from the US markets to the key EMEs during this period. The results suggest importance of careful communications by advanced economy central banks and the possibility of establishing ‘rules of the monetary game’. They also suggest that in the absence of international policy coordination to contain spillovers, EME central banks should build adequate buffers and reinforce financial stability ahead of the reversal of the global interest rate cycle.     

The lower bound and the causes of monetary policy inertia: evidence from Sweden

In 2009, in the midst of a global recession, Sweden’s Riksbank approached a lower bound on nominal interest rates. This encounter with the lower bound provides a natural experiment for investigating the causes of monetary policy inertia. To exploit this experiment, we estimate Taylor rules with Tobit specifications that permit both interest rate smoothing and persistent shocks (serial correlation) as explanations for inertia. The interest rate smoothing hypothesis leads to a specification in which lagged actual values of the dependent variable appear on the right-hand side of the Taylor rule, while the persistent shocks hypothesis leads to a specification in which lagged values of an unobserved latent dependent variable appear on the right-hand side of the Taylor rule. The divergence of actual and latent dependent variables that occurs at the lower bound provides leverage in distinguishing the two hypotheses. For a conventional Taylor rule, we find evidence of both sources of inertia. For a modified Taylor rule that includes a measure of financial stress, our evidence suggests that interest rate smoothing is the principal source of monetary policy inertia.     

Output gap uncertainty: Does it matter for the Taylor rule?

This paper analyses the effect of measurement error in the output gap on efficient monetary policy rules in a simple estimated model of the US economy. While it is a well-known result that such additive uncertainty does not affect the optimal feedback rule in a linear-quadratic framework, it is shown that output gap uncertainty can have a significant effect on the efficient response coefficients in restricted instrument rules such as the popular Taylor rule. Output gap uncertainty reduces the response to the current estimated output gap relative to current inflation and may partly explain why the parameters in estimated Taylor rules are often much less than what optimal control exercises which assume the state of the economy is known suggest.

Fed and ECB monetary policy spillovers to Emerging Market Economies

This paper presents evidence that the international spillovers of both Fed and ECB conventional monetary policies to Emerging Market Economies (EMEs) are global. The result comes from the panel Bayesian Vector Autoregressive (BVAR) model estimated for EMEs in which we control i.a. for foreign central banks’ policy shocks. Furthermore, in the separate BVAR model for Central and Eastern European (CEE) countries we show that the ECB is the main foreign central bank for these economies — after controlling for its shocks, their Fed counterparts play a very moderate role in driving GDP and prices in CEE.     

Monetary Policy Rules for Transition Economies: An Empirical Analysis

In this paper, we investigate the monetary policy reaction functions for the new European Union member states. We find interesting differences when looking at both interest rates (the Taylor rule) and monetary base (the McCallum rule) as monetary policy rules. Monetary aggregate is more likely to react to the deviation of inflation from its target, while short‐term interest rates are highly sensitive to the deviation of exchange rates in the Czech Republic, Poland, Slovakia, and Slovenia. For Hungary and Romania, both interest rates and money are responsive to inflation. In empirical literature, much attention is paid to the use of the Taylor‐type rule for developed economies. However, our empirical results raise questions on the reliance of this rule for these transition economies.     

Interest rates,government purchases and the Taylor rule in recessions and expansions

In this paper we study asymmetries in the Taylor rule for the United States during the 1970–2012 period. We show that monetary authorities have been constantly concerned with excess demand in overheated periods – when the output gap is positive or the unemployment rate falls below 7% or 7.5% – raising the interest rate aggressively in that case. However, the Fed seems more reluctant to decrease the fund’s rate during recessions. On the contrary, monetary authorities react symmetrically and forcefully to inflation in booms and busts. Finally, we provide evidence that an expansionary fiscal policy does not lead to an increase in interest rates, and thus there is not necessary a “crowding-out” effect in recessions.     

A comparison of optimal policy rules prior to and during inflation targeting: empirical evidence from Bank of Canada

We examine policy rules that are consistent with inflation targeting (IT) framework in a small macroeconomic model of the Canadian economy. We set up an optimal linear regulator problem and derive policy rules to compare the dynamics of pre-IT and IT eras. We find that while the optimal monetary policy rule in the pre-IT period is best described with a loss function that attaches equal weight to price stability, financial stability and output stability; the IT era is dominated by the price stability objective followed by the financial stability and output stability, consecutively. Moreover, we do not find an explicit role for exchange rate stability in the objective function of the Bank of Canada for both monetary policy eras. We, then, compare the properties of the derived optimal rules with those of an ad hoc Taylor rule for the IT period. In response to inflationary shocks, Taylor rule brings down inflation rates more quickly compared to the derived policy rules, but at the cost of a higher sacrifice ratio and more volatile interest rates.     

On the Effects of Asset Purchase Programs on Emerging Stock Markets

ABSTRACT

It is well documented that there has been a relationship between stock markets and unconventional monetary policies. However, most research concentrates on developed economies and analyzes the effects of shocks from such polices on stock prices. This paper is different from this research in that we investigate the impact of surprises from the Fed’s and the ECB’s announcements on the stock returns and volatility in Gulf Cooperation Council (GCC) countries using GARCH models. We find that a positive surprise associated with a fall in the U.S. Treasury yield causes an increase in ADX returns. We show significant effects of the ECB’s shocks on price returns. In particular, announcement that induces a decline in yield spreads in Italian sovereign bonds leads to higher stock prices. We also document a significant impact of surprises both by the Fed and ECB on volatility. However, the estimates are mixed. We note that volatility went down in response to the ECB’s policies, while they increased after the Fed’s asset purchases. Finally, when we distinguish surprises by their sign, the GJR-GARCH model estimates indicate that the effect on the volatility which is, perhaps surprisingly, symmetric for both types of news.     

MISPERCEPTIONS AND MONETARY POLICY IN A NEW-KEYNESIAN MODEL

This paper studies the consequences for the monetary policy design of information shortages on the part of the private sector. We model these shortages as exogenous shocks to expected income, which through an IS curve, disturb aggregate demand. We constrain policymakers to follow Taylor‐like rules but allow them to optimise coefficients: we find that the presence of misperceptions makes the optimised Taylor rule respond more aggressively to inflation and the output gap. We also find that if the policymaker is uncertain about misperceptions, then it is less costly to assume they are pervasive when they are not than the reverse. In other words, setting policy on the basis that the private sector is subject to misperceptions is a ‘robust’ policy.     

Unconventional monetary policy and the dollar–euro exchange rate: first results from time-series analysis

This article examines the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (Fed) and the European Central Bank (ECB). To that end, we make use of time-series analysis to obtain a reasonable long-run and short run representation of the data generation process and use dummy variables to study how announcements about monetary policy changes can affect the USD–EUR exchange rate. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused an appreciation of the dollar, while those by the Fed would have caused a depreciation of the dollar.     

Is the Taylor Rule Really Different from the McCallum Rule?

When base velocity is a stable function of the Federal funds rate (FFR), the money base–nominal GDP targeting rule (McCallum rule) can be reparameterized and presented in terms of FFR as the policy instrument. Comparison of this McCallum modified policy rule with the popular Taylor rule suggests that these two rules and the FFR are actually closely related. Model-based evaluations of the two rules' stabilization properties indicate that the modified McCallum rule is similar to the Taylor rule. The key to this result is the degree of interest rate smoothing applied to the policy rules. (JEL E3 , E52 , E58 )
