Evolving dynamics of the relationship between US core inflation and unemployment

Labor market dynamics in the US are changing due to long-term factors including decelerating labor force growth, rising age of the labor force, and the rapid advance of e-commerce, as well as the one-time downward adjustment during 2009–2013 of the size of state and local government work forces. We discuss some of the controversies revolving around how to analyze labor markets in this dynamic environment from the perspective of monetary policymaking, given the dual mandate of the Federal Reserve to encourage both full employment and price stability.Our statistical research documents the changing association between US unemployment and core inflation. There was a perceived trade-off between inflation and unemployment in the 1950s and 1960s that gave way to stagflation in the 1970s, when both unemployment and inflation were rising. The 1980s were a transition period where the trade-off was perceived to have returned. This trade-off has not been so clear, however, when one looks at the last twenty years. Since 1995, a period of stable and low inflation was consistently observed despite considerable cycles in the unemployment rate.Our theoretical discussion provides a dynamic interpretation of the shifting nature of labor markets, with the objective of pointing the way for future research while highlighting crucial differences in possible interpretations that could fuel debate, both inside and outside the Fed, over how the Fed should manage its dual mandate. The dynamic changes being seen in US labor markets all suggest that the effectiveness of monetary policy to encourage full employment may be vastly overstated. If this interpretation is correct, the Fed may need to reconsider how to manage its dual mandate and react less aggressively to perceived labor slack that may be due to longer-term structural shifts over which the Fed has no influence.     

Modelling sovereign credit spreads with international macro-factors: The case of Brazil 1998–2009

This paper develops a macro-finance model of the Brazilian economy and its sovereign debt markets that allows for domestic and international macroeconomic influences as well as swings in investor confidence. It finds significant evidence of common trends in the US and Brazilian economies and bond markets as well as spillover effects from US inflation and business cycles to the Brazilian economy. The US Fed Funds rate influences Brazilian sovereign spreads, as do Brazilian inflation and policy rates. The Brazilian confidence factor dominates the behavior of the spreads during periods of crisis and we find that it also has a powerful effect on the level and volatility of macroeconomic variables. These results suggest that the macro-finance approach could throw light upon the behavior of other economies that are troubled by sovereign risk.     

美联储停止缩表的原因、影响及中国对策

近期美联储停止缩表引起广泛关注。美联储停止缩表主要有以下几个原因:一是货币需求大幅上升,二是美联储控制短期利率的能力出现下降,三是美国经济前景存在不确定性。此外,美联储停止缩表还有助于继续发挥财政作用、改善货币政策传导效率、降低污名效应、降低私人部门安全资产的供应以及降低对美联储信用风险和银行清算风险。美联储停止缩表对美国和中国都会产生十分广泛的影响。对美国的影响主要有:资产价格将获得支撑、投资可能出现过热、通胀可能出现阶段性上升、金融风险可能加大、美联储独立性可能受到影响、可能加剧收益率曲线倒挂;对中国的影响主要有:人民币汇率压力有望缓解、资产价格可能上升、短期资本流入可能增多。因此,中国货币政策应保持定力,密切关注国际资本流动趋势的变化,防范资产价格暴涨风险,同时,应加强人民币汇率风险管理。     

The Central Banker as a Risk Manager: Estimating the Federal Reserve's Preferences under Greenspan

We derive a natural generalization of the Taylor rule that links changes in the interest rate to the balance of the risks implied by the dual objective of sustainable economic growth and price stability. This monetary policy rule reconciles economic models of expected utility maximization with the risk management approach to central banking. Within this framework, we formally test and reject the standard assumption of quadratic and symmetric preferences in inflation and output that underlies the derivation of the Taylor rule. Our results suggest that Fed policy decisions under Greenspan were better described in terms of the Fed weighing upside and downside risks to their objectives rather than simply responding to the conditional mean of inflation and of the output gap.

Role of monetary policy in a New Keynesian economy: a note from a laboratory experiment

This paper discusses an experimental study on the role of monetary policy within a New Keynesian macroeconomic framework. The novelty of this article is that each subject was asked to forecast both the inflation rate and output gap at the same time one period ahead, which is an improvement over the existing literature. We find that if both the expected inflation rate and expected output gap is incorporated in the monetary policy rule then inflation can be anchored and stabilized more efficiently.     

Effects of monetary policy on the REIT returns: Evidence from the United Kingdom

In this paper, we analyze whether a monetary policy based on three main variables (inflation, money supply, and output gap) has a nonlinear impact on real estate investment trust (REIT) markets. In addition, we extend our analysis to examine whether these monetary policy components impact the possibility of boom and bust regimes occurring in the market. Empirically, we propose different Markov-switching model variants to determine the nonlinear time-varying impact of monetary policy on the REIT market. Our results show the monetary policy environment is supposed to affect, on one hand, the REIT returns and, on the other hand, the possibility of boom and bust markets. We prove that expansionary monetary policy has an impact only in the case of boom market. However, an increase in the inflation rate decreases the probability of remaining in the bust regime. As a consequence, we have already outlined several monetary transmission mechanisms that show house prices to have important effects on aggregate demand. Our results confirm that REIT markets are not efficient.     

Monetary policy and stock market dynamics across monetary regimes

This paper examines the dynamic linkages between monetary policy and the stock market during the three distinct monetary regimes of Burns, Volcker and Greenspan since the 1970s. Some major findings are the following. First, in the 1990s it appears that there was a disconnection between Federal Reserve actions (via the federal funds rate) and responses by the stock market. Second, the impact of inflation on the stock market did not surface as significant in the later parts of 1980s and the 1990s. And third, significant asymmetric effects of monetary policy on the stock markets were observed throughout each monetary regime but these were more pronounced during bear markets than bull markets. These results suggest that there was no consistent dynamic relationship between monetary policy and the stock market and that the nature of such dynamics was different in each of the three monetary regimes.     

FX Intervention in the New Keynesian Model

We develop an open-economy New Keynesian Model with foreign exchange (FX) intervention in the presence of a financial accelerator and shocks to risk appetite in international capital markets. We obtain closed-form solutions for optimal monetary and FX intervention policies assuming the central bank cannot commit to future policies, and we compare the solution to that under policy commitment. We show how FX intervention can help reduce the volatility of the exchange rate, of inflation, and of the output gap, thus mitigating welfare losses associated with shocks in the international capital markets. We also show that, when the financial accelerator is strong, there is a risk of indeterminacy (self-fulfilling currency and inflation movements) although FX intervention can reduce this risk and thus reinforce the credibility of the inflation targeting regime. Model simulations match well the impact of a VIX shock obtained by local projections on a panel of inflation targeting emerging markets.     

Output Gap Estimation and Monetary Policy in China

Using the Bayesian multivariate Beveridge-Nelson decomposition method, this paper estimates China's output gap based on a multivariate dynamic model featuring distinct interactions among real output, inflation, money, and the exchange rate in China during the period 1980-2010. The authors compare the statistical nature and potential forecasting effects of the resulting multivariate gap measure on monetary policy with those of the output gap measures based on univariate models. The empirical results show that only the measure based on the multivariate system significantly predicts monetary policy, which indicates that the output gap estimated by the multivariate system contains more information than the traditional measures for macroeconomic policy adjustments do.     

Inflation,Employment, and Monetary Policy: Objectives and Outcomes in the UK and U.S. Compared

This paper explores how sensitive is monetary policy to the precise preferences of the central bank over inflation and economic activity. It does so in order to address a puzzle—which is that the U.S. Fed and the Bank of England appear to have quite different objectives and yet have adopted strikingly similar policies in recent years. I use a calibrated model to assess how policy might be sensitive to attaching different weights to inflation, output, and the output gap in central bank objectives. I find that a wide range of weights can give rise to rather similar monetary policies.     

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.     

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.     

The Taylor Rule and “Opportunistic” Monetary Policy

We investigate the possibility that the Taylor rule should be formulated as a threshold process such that the Federal Reserve acts more aggressively in some circumstances than in others. It seems reasonable that the Federal Reserve would act more aggressively when inflation is high than when it is low. Similarly, it might be expected that the Federal Reserve responds more to a negative than a positive output gap. Although these specifications receive some empirical support, we find that a modified threshold model that is consistent with “opportunistic” monetary policy makes significant progress toward explaining Federal Reserve behavior.     

Stock liquidity and the Taylor rule

This paper examines how stock market liquidity and commonality in liquidity are impacted by real-time output gap and inflation, as these macroeconomic variables have been shown to be the main drivers of monetary policy according to the Taylor rule. We show that an increase in the output gap and inflation lowers stock liquidity and increases commonality in liquidity, since it points to a contractionary monetary policy and is likely to lead to a decline in the liquidity providers' funding liquidity. This effect is larger for stocks with low market capitalization and low liquidity.     

New Leadership at the Federal Reserve*

As Chairman of the Federal Reserve for the past 18 years, Alan Greenspan deserves praise for his stewardship of monetary policy. He has guided the Fed and monetary policy in a way that has led to low and stable inflation. But if Greenspan's record clearly deserves praise, he could have done more to move monetary policy into the 21st century and prepare the institution for the future. Greenspan has relied heavily on his personal judgment and has argued repeatedly that the Fed must have extensive flexibility to respond to the economic environment. But if Greenspan's judgment, skill, and luck have served him and the country well, it is dangerous to rely so heavily on the judgment of a single individual. When he departed, he took with him his skill and judgment, as well as his credibility and his personal commitment to low inflation. The Fed he leaves behind has no explicit institutional commitment to long‐run price stability. This article argues that by operating with a set of rules and guidelines, or at a minimum clearly stated institutional objectives, the Fed would eliminate much of the second guessing about what it is doing and why, and the associated volatility in markets. More generally, the benefits of more explicit guidelines for monetary policy include:

• ? Increasing public understanding of monetary policy, including what it can and cannot do.
• ? Increasing transparency and accountability. Most organizations have clear goals and we hold their leaders accountable. The Fed is different. The Fed seems to be held accountable for all things economic and thus it is truly accountable for nothing. It never has to explain its actions and what went right or wrong.
• ? Establishing a clear focus for the Fed regarding its goals and objectives.
• ? Creating increased confidence that sound monetary policy will be followed in the future.

     

Stock market reactions to monetary policy surprises under uncertainty

This article investigates how uncertainty impacts the effect of monetary policy surprises on stock returns. Using high-frequency US data, we demonstrate that stock markets respond more aggressively to monetary policy surprises during periods of high uncertainty. We also show that uncertainty asymmetrically influences the transmission of positive and negative monetary policy surprises to stock market prices. The amplifying effect of uncertainty is found to be stronger for expansionary shocks than for contractionary shocks. Our robustness analysis confirms that financial uncertainty has a significant role in shaping the influence of monetary policy on the stock market.     

Congress and the Federal Reserve

We examine legislative activity to determine when Congress threatens the Fed and whether this pressure affects monetary policy. By the late‐1980s Congress shifted from threatening when unemployment was high to threatening when inflation was high. We use the Romer and Romer monetary shocks to isolate changes in the federal funds rate that cannot be explained by economic conditions and ask whether these shocks respond to pressure. In the 1970s, the Fed responded to bills credibly threatening Fed powers by lowering the federal funds target below that prescribed by current and forecast economic conditions. However, this accommodation ceased in the mid‐1980s.
