Monetary Policy and the Lost Decade: Lessons from Japan

I investigate how monetary policy can avoid a deflationary slump when policy rates are near zero by studying interest rate policy during Japan's “Lost Decade.” Estimation results suggest that the Bank of Japan's interest rate policy fits a conventional reaction function with an inflation target near 1%. The disapointing economic performance thus seems primarily due to adverse economic shocks rather than extraordinary policy errors. Also, counterfactual policy simulations suggest that simply raising the inflation target would not have substantially improved performance. However, price‐level targeting or combining a higher inflation target with an aggressive output response would have achieved superior stabilization results.     

日本超宽松货币政策的历程、效果及启示

日本央行提前启动了开放式资产购买措施,显示了尽快实现2％通胀目标的决心,但其会否重蹈历史的覆辙,还是会一举扭转日本经济长期的窘境,值得关注。文章在梳理日本央行长期实施超宽松政策历程的基础上,分析日本超宽松政策的效果,探究其陷入“流动性陷阱”的原因,并从中总结实施超宽松货币政策的经验和教训,以便能更好地理解货币宽松政策的传导机制、效果与局限性。     

中央银行透明化政策与宏观经济稳定

在通胀预期管理背景下,构建中国2001~2013年中央银行信息交流指数,考量中央银行透明化政策影响宏观经济稳定机制。结果表明,央行增加信息交流有利于宏观经济稳定,某些情况下甚至超过实际干预的效果。因此,我国央行应进一步提高货币政策透明度并培育规范的中央银行信息交流机制。     

数量规则还是利率规则？——我国转型时期量价混合型货币规则的理论基础

本文对我国货币政策转型时期兼顾数量和价格的货币政策调控实践进行了深入的分析。在货币数量论和货币效用模型的基础上,从理论上阐明了货币数量规则与利率价格规则的等价关系,并构建了符合中国货币政策实践的数量与价格混合型货币政策规则。这对于更好地理解我国货币政策转型时期的量价混合型货币政策操作具有重要的理论和现实意义。相关推论表明,正是由于数量和价格混合型货币规则,在利率低于均衡水平的情形下,中国的货币增速并未引发恶性通胀;修正的物价稳定泰勒原理表明,利率调整幅度小于通胀变化仍能够实现物价稳定。对中国的经验分析支持了理论和推论结果。在利率市场化基本完成和流动性格局逆转的当下,货币政策价格调控方式转型的必要性和迫切性日益上升,转型的条件日趋成熟。     

Do central banks respond to exchange rate movements? A structural investigation

We estimate a small-scale, structural general equilibrium model of a small open economy using Bayesian methods. Our main focus is the conduct of monetary policy in Australia, Canada, New Zealand and the UK. We consider generic Taylor-type rules, where the monetary authority reacts in response to output, inflation, and exchange-rate movements. We perform posterior odds tests to investigate the hypothesis whether central banks do target exchange rates. The main result of this paper is that the central banks of Australia and New Zealand do not, whereas the Bank of Canada and the Bank of England do include the nominal exchange rate in its policy rule. This result is robust for various specification of the policy rule. We also find that terms-of-trade movements do not contribute significantly to domestic business cycles.

Deposit interest rate ceilings as credit supply shifters: Bank level evidence on the effects of Regulation Q

How did deposit interest rate ceilings, an important feature of the U.S. regulatory regime until the mid-1980s, affect individual banks’ lending and the transmission of monetary policy to credit? I estimate the effect of deposit rate ceilings inscribed in Regulation Q on commercial banks’ credit growth using a historical bank level data set starting in 1959. Banks’ credit growth contracted sharply when legally fixed deposit rate ceilings were binding. Interaction terms with monetary policy suggest that the policy impact on bank level credit growth was non-linear and significantly larger when rate ceilings were in place. Bank size and capitalization mitigate these effects. At the bank level, short-term interest rates exceeding the legally fixed deposit rate ceilings identify policy induced credit supply shifts that disappeared with deposit rate deregulation and thus weakened the bank lending channel substantially since the early 1980s.     

Estimating the credibility of Brazilian monetary policy using a Kalman filter approach

The objective of this study is to estimate the credibility of the monetary policy followed by the Central Bank of Brazil (BCB) during the period 2006–2015. To estimate this credibility, we use the Kalman filter in three measures of inflation expectation: two collected via market survey and via consumer polling, as well as the breakeven inflation. The results provide evidence of the existence of three shifts in the perceived credibility of BCB inflation targets during the period analyzed: (i) credibility declined sharply in mid-2008, at the most critical moment of the subprime mortgage crisis; (ii) credibility was relatively stable from early 2009 through mid-2013; (iii) credibility trended downward thereafter, when the real interest rate was less than the minimum rate compatible with the inflation target. By associating the estimated credibility with macroeconomic and financial variables, we find a downward trend in credibility during recessionary periods and an inverse relationship between credibility and output gap, between credibility and variation in the BRL/USD exchange rate, and between credibility and historical inflation. In addition, we find that market survey and breakeven inflation credibility measures are important in predicting sovereign risk. Furthermore, changes in the inflation rate are important for predicting only credibility measured on consumer polling, validating the assumption that measures from consumer polls are backward-looking and formed based on consumers’ adaptive expectations.     

U.S. Monetary Regimes and Optimal Monetary Policy in the Euro Area

Monetary policy in the United States has been documented to have switched from reacting weakly to inflation fluctuations during the 1970s, to fighting inflation aggressively from the early 1980s onward. In this paper, I analyze the impact of the U.S. monetary policy regime switches on the Eurozone. I construct a New Keynesian two‐country model where foreign (U.S.) monetary policy switches regimes over time. I estimate the model for the U.S. and the Euro Area using quarterly data and find that the United States has switched between those two regimes, in line with existing evidence. I show that foreign regime switches affect home (Eurozone) inflation and output volatility and their responses to shocks, substantially, as long as the home central bank commits to a time‐invariant interest rate rule reacting to domestic conditions only. Optimal policy in the home country instead requires that the home central bank reacts strongly to domestic producer‐price inflation and to international variables, such as imported goods relative prices. In fact, I show that currency misalignments and relative prices play a crucial role in the transmission of foreign monetary policy regime switches internationally. Interestingly, I show that only marginal gains arise for the Euro Area when the European Central Bank (ECB) adjusts its policy according to the monetary regime in the United States. Thus, a simple time‐invariant monetary policy rule with a strong reaction to Producer Price Index (PPI) inflation and relative prices is enough to counteract the effects of monetary policy switches in the United States.     

Inventory Dynamics and Business Cycles: What Has Changed?

To what extent can information-technology led improvements in inventory management account for the apparent moderation of economic fluctuations in the United States since the mid-1980s? We argue that changes in inventory dynamics played a reinforcing—rather than a leading—role in the reduction of output volatility. Since the mid-1980s, inventory dynamics have changed in a manner consistent with a faster resolution of inventory imbalances. However, these changes appear to be a consequence of changes in the response of industry-level sales and aggregate economic activity to monetary policy shocks. Our results suggest that it is the interaction between the changes in inventory behavior at the industry level and the macroeconomic environment—where the latter likely includes changes in the conduct of monetary policy and the responses of the economy to policy disturbances—rather than any single factor, that has contributed importantly to the observed decline in economic volatility.     

Three aspects of the Swiss term structure: an empirical survey

The term structure is an important transmitter of, and indicator for, monetary policy. This paper studies the Swiss term structure using monthly data from 1989 to 2005. We study the impact of the new monetary policy strategy that the Swiss National Bank (SNB) adopted at the beginning of 2000 on three aspects of the term structure. First, we test the expectations hypothesis and find it confirmed at the short end of the yield curve. At the long end, time-varying term premia seem present. Second, we ask whether the yield curve contains information regarding future inflation and economic activity. We find that a steepening of the yield curve predicted an increase in economic activity in the short term before the change in policy strategy, but not thereafter. Third, we study the contemporaneous reaction of the term structure to macroeconomic conditions and conclude that the SNB’s commitment to stabilizing inflation may have become more credible after the change in the monetary policy strategy.      

Tracking U.S. inflation expectations with domestic and global indicators

Are foreign variables important for tracking U.S. inflation expectations? This paper estimates a reduced-form model that takes both domestic and global indicators of economic slack and inflationary pressures into account. Our main findings point towards the instability of the estimated parameters over the last four decades. In particular, global indicators appear to have played a statistically significant role in shaping forecasters’ expectations until the mid-1980s. By contrast, the U.S. monetary policy stance turns out to be relevant in the 1980s and 1990s. We relate this finding to the more aggressive monetary policy conduct implemented by the Fed since the end of the Volcker experiment.     

Quantitative Goals for Monetary Policy

We study empirically the macroeconomic effects of an explicit de jure quantitative goal for monetary policy. Quantitative goals take three forms: exchange rates, money growth rates, and inflation targets. We analyze the effects on inflation of both having a quantitative target and hitting a declared target. Our empirical work uses an annual data set covering 42 countries between 1960 and 2000, and takes account of other determinants of inflation (such as fiscal policy, the business cycle, and openness to international trade) and the endogeneity of the monetary policy regime. We find that both having and hitting quantitative targets for monetary policy is systematically and robustly associated with lower inflation. The exact form of the monetary target matters somewhat (especially for the sustainability of the monetary regime) but is less important than having some quantitative target. Successfully achieving a quantitative monetary goal is also associated with less volatile output.     

Learning and the monetary policy strategy of the European Central Bank

This paper examines the welfare implications of alternative inflation targeting proposals for the monetary policy of the European Central Bank. We assume that policy makers have to “learn” the laws of motion of inflation in an economy characterized by “stickiness” in domestic price setting behavior and subjected to recurring shocks to productivity, exports and foreign price. We find that a switch from an “asymmetric” inflation targeting strategy to an “symmetric” makes little difference in welfare payoffs, but it comes at a cost of much higher interest-rate variability. We also find that there are practically no welfare gains from switching from an inflation-targeting strategy based on the Harmonized Index of Consumer Prices (HICP) to a strategy based on the domestic price component of the HICP.     

The impact of international spillovers on Swiss inflation and the exchange rate

Understanding the effects and transmission of international spillovers is key to ensuring that the best possible decisions are reached by central banks – particularly those of small open economies. This paper analyses the impact of international spillovers on Swiss inflation and the exchange rate, and examines the response of the Swiss National Bank (SNB) to these phenomena. In doing so, the paper compares the recent crisis period starting in mid-2008 with earlier decades. While the exchange rate absorbed a sizeable share of global inflationary pressure before the crisis, spillover effects transmitted through the exchange rate have been the principal cause of the significant decline in Swiss inflation since 2008. The SNB has therefore repeatedly adjusted its monetary policy – and resorted to some unconventional measures – in order to contain these spillover effects. These actions have so far kept the adverse effects of international spillovers on Swiss inflation at bay. However, as Switzerland's experience since the onset of the financial crisis shows, controlling inflation may occasionally become more difficult for small open economies.     

The global credit boom: Challenges for macroeconomics and policy

The recent financial crisis has put the spotlight on the rapid rise in credit which preceded it. In this paper, we provide an empirical and theoretical analysis of the credit boom and the macroeconomic context in which it developed. We find that the boom was unusually long and associated with neither particularly strong growth nor rising inflation in the economies in which it took place. We show that this type of credit and financial cycle is hard to reconcile with existing economic theory and argue that, while the “global savings glut” may account for the cycle's initial phase, other factors – such as the conduct of monetary policy and perceptions of declining macroeconomic risk – were more important from the mid-2000s onwards. We conclude by identifying some of the challenges now facing macroeconomics and policy.     

Monetary control with an exchange rate objective: The bank of Japan, 1973–86

This paper analyzes the switch in monetary control procedures by the Bank of Japan toward a so-called ‘money-focused’ monetary policy in the mid-1970s. The extent to which monetary control under the new regime has been limited by an exchange rate objective is examined. Through estimation of an explicit Bank of Japan (BoJ) reaction function, we find evidence that the BoJ operating instrument has been systematically manipulated with a view to maintain short-term money control but that this objective has often been dominated by an attempt to moderate yen– dollar exchange rate fluctuations.     

Estimating Monetary Policy Rules When Nominal Interest Rates Are Stuck at Zero

Did the Federal Reserve's response to economic fundamentals change with the onset of the Global Financial Crisis? Estimation of a monetary policy rule to answer this question faces a censoring problem since the interest rate target has been set at the zero lower bound since late 2008. Surveys by forecasters allow us to sidestep the problem and to use conventional regressions and break tests. We find that, in the opinion of forecasters, the Fed's inflation response has decreased and the unemployment response has increased, which suggests that the Federal Reserve's commitment to stable inflation has become weaker in the eyes of the professional forecasters.
