How the ECB and the US Fed set interest rates

Monetary policies of the European Central Bank (ECB) and US Fed can be characterized by ‘Taylor rules’, that is both central banks seem to be setting rates by taking into account the ‘output gap’ and inflation. We also set up and tested Taylor rules which incorporate money growth and the euro–dollar exchange rate, thereby improving the ‘fit’ between actual and Taylor rule based rates. In general, Taylor rules appear to be a much better way of describing Fed policy than ECB policy. Simulations suggest that the ECB's short-term interest rates have been at a much lower level in the last 2 years compared with what a Taylor rule would suggest.     

TAYLOR RULE REACTION COEFFICIENTS AND REAL EXCHANGE RATE PERSISTENCE

Recent literature has established a link between the persistence of real exchange rates and the degree of inertia in Taylor rule monetary policy reactions functions. This paper provides a different view on this link by investigating how the size of Taylor rule reaction coefficients impacts the adjustment dynamics of the real exchange rate. Within a stylized sticky‐price open‐economy macro model, it is demonstrated that a stronger interest rate reaction to inflation in the Taylor rule raises the convergence speed of the real exchange rate. Conversely, raising the coefficient on the output gap or attending to the exchange rate in an open‐economy version of the Taylor rule slows down real exchange rate adjustment. In all cases, more rapid convergence comes at the cost of stronger initial real exchange rate misalignments in the wake of monetary policy shocks.     

Sources of exchange rate fluctuations with Taylor rule fundamentals

This paper investigates the sources of exchange rate fluctuations when monetary policy follows a Taylor rule interest rate reaction function. We first present a simple dynamic exchange rate model with Taylor rule fundamentals which is triangular in the long-run impacts of shocks to the output market, the interest rate differential, and the Taylor rule. We then proceed to assess the relative importance of various shocks in exchange rate determination by estimating a structural VAR with long-run identification restrictions based on the triangular structure of the model. We find demand shocks to be less important than in earlier VAR studies, with both supply shocks and nominal shocks explaining a substantial part of real exchange rate fluctuations.     

Real exchange rate dynamics: Relative importance of Taylor‐rule fundamentals,monetary policy shocks,and risk‐premium shocks

We first show that the solution to the real exchange rate under the Taylor rule with interest rate smoothing can have two alternative representations—one based on a first‐order difference equation and the other based on a second‐order difference equation. Then, by comparing error terms from these two alternative representations and analyzing their second moments, we evaluate the relative importance of Taylor‐rule fundamentals, monetary policy shocks, and risk‐premium shocks in the dynamics of the real exchange rate. Empirical results suggest that the risk‐premium shock is the largest contributor to real exchange rate movements for all the countries examined, with the Taylor‐rule fundamentals and monetary policy shocks playing a limited role. These results are robust to various alternative sets of parameter values considered for the Taylor rule with interest rate smoothing.     

流动性过剩背景下货币政策工具的特点及政策选择

在双顺差快速增长的背景下,数量型货币政策工具的紧缩效果在较短时间内即被外汇占款增长所抵消。名义利率调整滞后于价格水平上涨导致真实利率下降,在一定程度上进一步抵消了货币当局通过数量工具收缩流动性的效果。在宏观经济存在潜在过热风险的情况下,货币政策可依据泰勒规则加强对名义利率的调整,避免宏观经济的过度波动。     

Central Bank Behavior, the Institutional Framework, and Policy Regimes: Inflation Versus Noninflation Targeting Countries

This article estimates central bank reaction functions for 20 OECD countries. It bridges the gap between the Taylor reaction function literature and the political-economy literature. Central banks react to both inflation and the output gap. Moreover, inflation-targeting countries have been able to reduce nominal interest rate to a greater extent than have non-inflation-targeting countries. Countries with fixed exchange rates react more strongly to inflation but not at all to the output gap, unlike countries with floating rates. Political influences also seem relatively more important in fixed exchange rate countries. Central bank independence also helps reduce nominal interest rates. (JEL E58 , C31 , C32 , C53 )     

Capital Inflows,Dutch Disease Effects,and Monetary Policy in a Small Open Economy

This paper studies the role of monetary policy in a small open economy that experiences Dutch disease effects as a result of capital inflows, and examines the issue of whether such a policy should seek to address these effects from a welfare perspective. I find that Dutch disease effects occur under a fixed nominal exchange rate regime. However, a monetary policy regime characterized by generalized Taylor interest rate rules featuring either the real exchange rate or the nominal exchange rate avert Dutch disease effects. Welfare results reveal that the optimal rule is a generalized Taylor rule consistent with nominal exchange rate flexibility.     

Dissecting Exchange Rates and Fundamentals in the Modern Floating Era: The Role of Permanent and Transitory Shocks

In this paper, we apply a permanent–transitory decomposition method to analyze the link between nominal exchange rates and fundamentals in the modern floating era. The results suggest that transitory shocks dominate nominal exchange rate fluctuations, while permanent shocks dominate the variations in fundamentals. Therefore, the findings suggest that the nominal exchange rate should not be approximated by a pure random walk. Moreover, we find that unobserved fundamentals in the Taylor rule model can explain the transitory components in exchange rates.     

Purchasing power parity over two centuries: trends and nonlinearity

In two recent contributions Lothian and Taylor, and Cuddington and Liang, produced empirical evidence that annual data for the dollar-sterling real exchange rate spanning two centuries exhibited a non-linear deterministic trend. This trend could be proxying Harrod-Balassa-Samuelson effects. Lothian and Taylor showed that a linear stationary autoregressive mode, which embodied a cubic trend, implied much faster mean reversion of the real exchange rate to shocks than a model that excluded the trend. This article shows that both non-linearity and a deterministic trend can be allowed for in a theoretically appealing manner and that the fitted models provide a parsimonious explanation of both the dollar-sterling and franc-sterling real exchange rates over the two centuries of data. Generalized impulse response function analysis of the models demonstrates that the speed of adjustment to shocks can be even faster when trends are considered.     

What Does the Taylor Rule Say About a New Zealand–Australia Currency Union?*

It has been suggested that the New Zealand economy may have similar characteristics and face similar shocks to some Australian states, so lowering the costs of a trans‐Tasman currency union. We test this, under the assumption that differences in Taylor rule‐implied interest rate paths for different regions give an indication of differences in aggregate shocks that hit different economies. We compare implied Taylor rule interest rates for each of the Australian states to implied Taylor rule rates for New Zealand. We also compare them to realised 90‐day rates. We find that the Taylor rule‐implied rates in Australian states and in New Zealand are similarly correlated with actual Australian interest rates.     

The Taylor Rule and Dynamic Stability in a Small Macroeconomic Model

In this paper, we embed the Taylor interest rate rule in a simple macroeconomic model with Calvo contracts. We contrast this with the case in which the interest rate is determined by the conventional LM curve along with a fixed value for the monetary aggregate. We derive conditions under which the adjustment of the economy is characterized by a unique saddle–path and show that the conditions required for this to be the case are more stringent when the authorities adopt the Taylor rule. In both cases, the possible failure of the saddle–path condition arises when there are debt–deflation effects in the IS curve. If interest rates are set according to the Taylor rule, then debt–deflation is always enough to cause the failure of the saddle–path condition. However, when interest rates are determined by the LM curve then it is possible that the real balance effect from the LM curve may offset the debt–deflation effect and produce a saddle–path.

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.     

The coordination channel of foreign exchange intervention: A nonlinear microstructural analysis

Taylor (1994, 1995) [Taylor, M.P., 1994. Exchange rate behaviour under alternative exchange rate regimes. In: Kenen, P. (Ed.), Understanding Interdependence: The Macroeconomics of the Open Economy. Princeton University Press, Princeton; Taylor, M.P., 1995. The economics of exchange rates. Journal of Economic Literature 33, 13-47] has proposed the coordination channel as a means by which foreign exchange market intervention may be effective, in addition to the traditional portfolio balance and signalling channels. If strong and persistent misalignments of the exchange rate are caused by nonfundamental influences, such that a return to equilibrium is hampered by a coordination failure among fundamentals-based traders, then official intervention may act as a coordinating signal, encouraging stabilising speculators to re-enter the market at the same time. We develop this idea in the framework of a simple microstructural model of exchange rate movements, which we then estimate using daily data on the dollar-mark exchange rate and on Federal Reserve and Bundesbank intervention operations. The results are supportive of the existence of a coordination channel of intervention effectiveness.     

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.     

Monetary transmission mechanism in Turkey under the monetary conditions index: an alternative policy rule

This study analyses monetary transmission mechanism in Turkey using a small structural macroeconomic model. The core equations of the model consist of aggregate demand, wage-price setting, uncovered interest rate parity, foreign sector and a monetary policy rule. The aim of the paper is to analyse the disinflation path, the output gap, the output level, the exchange rate and the interest rate, and also the output–inflation variance frontier of the economy under various scenarios. The first scenario assumes that a standard Taylor rule is implemented as the policy rule. In the alternative scenario, instead of the standard Taylor rule, the MCI, Monetary Conditions Index – combination of the changes in the short-term real interest rate and in the real effective exchange rate in a single variable – is used as a policy instrument. The results indicate that the economy stabilizes much more quickly and shows significantly less volatility under this new setting. Therefore, the paper concludes that the policymakers should consider using MCI as an instrument when conducting monetary policy.     

Currency Boards when Interest Rates are Zero

In a fixed exchange rate system, any expectation that the peg may be abandoned will normally be reflected in an interest rate differential between instruments denominated in domestic and anchor currencies: the possibility of a revaluation will drive domestic interest rates below those in the anchor currency, for example. However, when interest rates are close to the zero lower bound, there is limited scope for exchange rate expectations to be reflected in interest rate differentials. Here we introduce a new mechanism, based on the central bank balance sheet, which works to bring about equilibrium in currency markets even when interest rates are zero. An expectation of exchange rate appreciation will cause foreign exchange reserves to swell, increasing the cost to policy‐makers of allowing an appreciation and, therefore, lowering the likelihood of the fixed exchange rate being abandoned. Under normal circumstances, this channel reinforces the equilibrating effect of interest rate differentials. When interest rates cannot adjust only this channel operates, implying that much larger changes in reserves are required to equilibrate currency markets. We develop a simple model to illustrate these arguments and find support for the predictions of the model using data for Hong Kong, the world's largest economy with a currency board.     

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.     

An inventory of simple monetary policy rules in a New Keynesian macroeconomic model

We derive necessary and sufficient conditions for simple monetary policy rules that guarantee equilibrium determinacy in the New Keynesian monetary model. Our modeling framework is derived from a fully specified optimization model that is amenable to analytical characterisation. The monetary rules analyzed are variants of the basic Taylor rules ranging from simple inflation targeting (current, forward, backward) to canonical Taylor rules with and without inertial nominal interest rates. We establish that determinacy obtains for a wide range of policy parameters, especially when the monetary authority targets output and smoothes interest rates. Contrary to other results in the literature, we do not find a case for super-inertial interest rate policy.     

Exchange Rate Regimes and Welfare Losses from Foreign Crises: The Impact of the US Financial Crisis on Mexico

We modify the Gali and Monacelli small open economy dynamic stochastic general equilibrium (DSGE) model, calibrate to Mexican data and simulate the impact of the financial crisis on Mexico, under floating and counter factual fixed exchange rates. The floating exchange rate ameliorates welfare losses for Mexico. They are greater under fixed exchange rates because the return paths to equilibrium are more volatile (higher variance) and output, consumption and employment impulse response functions (IRFs) overshoot. Monetary policy, inflation targeting with floating exchange rates, clearly reduced the welfare costs vis‐à‐vis other counter factual policies including consumer price index‐based Taylor rule, domestic inflation Taylor rule and fixed exchange rates.     

Modifying Taylor reaction functions in the presence of the zero‐lower‐bound — Evidence for the ECB and the Fed

We propose an alternative way of estimating Taylor reaction functions if the zero‐lower bound on nominal interest rates is binding. This approach relies on tackling the real rather than the nominal interest rate. So if the nominal rate is (close to) zero central banks can influence the inflation expectations via quantitative easing. The unobservable inflation expectations are estimated with a state‐space model that additionally generates a time varying series for the equilibrium real interest rate and the potential output — both needed for estimations of Taylor reaction functions. We test our approach for the ECB and the Fed within the recent crisis. We add other explanatory variables to this modified Taylor reaction function and show that there are substantial differences between the estimated reaction coefficients in the pre‐ and crisis era for both central banks. While the central banks on both sides of the Atlantic act less inertially, put a smaller weight on the inflation gap, money growth and the risk spread, the response to asset price inflation becomes more pronounced during the crisis. However, the central banks diverge in their response to the output gap and credit growth.
