The impact of unconventional monetary policy on the tail risks of stock markets between U.S. and Japan

Facing the economic downturn, the central bank of U.S. and Japan adopts the unconventional monetary policy to stimulate their economy. This paper studies the quantitative easing policy effectiveness via the tail risks of stock markets in the U.S., Japan and the other 74 countries. Although the stock markets of U.S. and Japan reveals the announcement-day effects of the QE policy, this study finds an asymmetric tail risk of return distribution on the QE policy effect. The post-period right-tail and left-tail risks of the stock markets are significantly smaller and larger than that of the pre-period of the QE programs, respectively. This implies that the tail risks of stock returns have dissimilar interdependence with the QE programs. Furthermore, the geographical dependence is the major factor that determines the contagion of stock market, and the fragility of foreign stock market caused by the US QE policy is larger than that of the Japan.     

The Credit Channel at the Zero Lower Bound through the Lens of Equity Prices

This study examines the impact of unconventional monetary policies on the stock market when the short‐term nominal interest rate is stuck at the zero lower bound (ZLB). Unconventional monetary policies appear to have significant effects on stock prices and the effects differ across stocks. In agreement with existing credit channel theories, I find that firms subject to financial constraints react more strongly to unconventional monetary policy shocks [especially large‐scale asset purchases (LSAPs)] than do less constrained firms. These results imply that the credit channel is as important as the interest rate channel in the transmission of unconventional monetary policies at the ZLB.     

Cash holdings and share repurchases: International evidence

In this study, we examine the patterns and determinants of share repurchases using firm-level data from seven major countries—Australia, Canada, France, Germany, Japan, the U.K., and the U.S.—over the period 1998–2006. We find that while non-U.S. firms do not repurchase shares as much as U.S. firms do, both U.S. and non-U.S. firms display a common set of share repurchase behaviors. For example, across countries, firms use share repurchases as a flexible means of distributing cash. More importantly, large cash holdings are significantly associated with the amount of share repurchases in all countries. There is evidence that large cash holdings held by repurchasing firms represent excess cash. Firms tend to experience substantial increases in cash holdings prior to share repurchase as a result of reductions in capital expenditures. Overall, our evidence lends support to two hypotheses: (i) firms discharge excess capital to reduce agency conflicts and (ii) firms use repurchases to distribute temporary cash flows.     

U.S. Monetary Policy and International Bond Markets

This paper analyzes how U.S. monetary policy affects the pricing of dollar‐denominated sovereign debt. We document that yields on dollar‐denominated sovereign bonds are highly responsive to U.S. monetary policy surprises—during both the conventional and unconventional policy regimes—and that the passthrough of unconventional policy to foreign bond yields is, on balance, comparable to that of conventional policy. In addition, a conventional U.S. monetary easing (tightening) leads to a significant narrowing (widening) of credit spreads on sovereign bonds issued by countries with a speculative‐grade credit rating but has no effect on the corresponding weighted average of bilateral exchange rates for a basket of currencies from the same set of risky countries; this indicates that an unanticipated tightening of U.S. monetary policy widens credit spreads on risky sovereign debt directly through the financial channel, as opposed to indirectly through the exchange rate channel. During the unconventional policy regime, yields on both investment‐ and speculative‐grade sovereign bonds move one‐to‐one with policy‐induced fluctuations in yields on comparable U.S. Treasuries. We also examine whether the response of sovereign credit spreads to US monetary policy differs between policy easings and tightenings and find no evidence of such asymmetry.     

The impact of COVID-19 pandemic on transmission of monetary policy to financial markets

This study uses event-study methodology to estimate the impact of the COVID-19 pandemic on the transmission of monetary policy to financial markets, based on a sample of 37 countries with severe pandemics. Financial markets include government bond, stock, exchange rate and credit default swap markets. The results suggest that the emergence of pandemic has weakened the transmission of monetary policy to financial markets to a more significant degree. During our sample period following the outbreak of pandemic, neither conventional nor unconventional monetary policies have significant effects on all four of the financial markets. Of course, the unconventional monetary policies are slightly more effective as they can affect the stock and exchange rate markets to some extent. Therefore, in the post-pandemic period, if the monetary policy is used to stimulate financial markets, stronger policy adjustments, or other macro policies such as fiscal policies, may be needed to achieve the desired effect     

Stock price behavior surrounding stock repurchase announcements: Evidence from Japan

This paper examines stock price behavior surrounding announcements of stock repurchases made by Japanese firms from 1995 to 1998. Our analysis shows that, much as in the case of the U.S. markets, stock prices in Japan go up in response to stock repurchase announcements. We also find that there is no significant difference between the market reaction to the announcement for intention of repurchase execution and the market reaction to the announcement of an article alteration to allow stock repurchases. On the other hand, there is a significant difference in the pre-announcement period returns motivating these two announcements. While a large decline in stock price will motivate a firm to execute a stock repurchase, a smaller price decline will motivate a firm to merely alter its articles of association to allow future repurchases.     

U.S. monetary policy indicators and international stock returns: 1970-2001

It is documented in the literature that U.S. and many international stock returns series are sensitive to U.S. monetary policy. Using monthly data, this empirical study examines the short-term sensitivity of six international stock indices (the Standard & Poor 500 [S&P] Stock Index, the Morgan Stanley Capital International [MSCI] European Stock Index, the MSCI Pacific Stock Index, and three MSCI country stock indices: Germany, Japan, and the United Kingdom) to two major groups of U.S. monetary policy indicators. These two groups, which have been suggested by recent research to influence stock returns, are based on the U.S. discount rate and the federal funds rate. The first group focuses on two binary variables designed to indicate the stance in monetary policy. The second group of monetary indicators involves the federal funds rate and includes the average federal funds rate, the change in the federal funds rate, and the spread of the federal funds rate to 10-year Treasury note yield. Dividing the sample period (1970-2001) into three monetary operating regimes, we find that not all policy indicators influence international stock returns during all U.S. monetary operating periods or regimes. Our results imply that the operating procedure and/or target vehicle used by the Federal Reserve Board (Fed) influences the efficacy of the policy indicator. We suggest caution in using any monetary policy variable to explain and possibly forecast U.S. and international stock returns in all monetary conditions.     

Legal Institutions,Ownership Concentration,and Stock Repurchases Around the World: Signal Mimicking?

One of the central puzzles of signaling theory is how to assess signal quality, in particular the potential for signal mimicking. Our study provides evidence of signal mimicking in the context of stock repurchases. Employing an ex-ante proxy for the likelihood of mimicking stock repurchases and data on open market stock repurchases from 30 countries, we find that long-term operating and market performance following stock repurchases improve less for suspected mimicking firms. This finding contradicts the conventional characterization that managers use stock repurchases to signal undervaluation and enhanced future performance. We find that mimicking firms have smaller capital investments, need greater external financing, buy back fewer shares, and issue more new shares (and/or resell more treasury shares) in the year of the repurchase. Our analysis further shows that mimicking is more likely in countries with weak investor protections and in firms with higher ownership concentration. Further, mimicking associated with concentrated ownership is mitigated in countries with stronger investor protections and by the adoption of International Financial Reporting Standards (IFRS). Altogether, our findings provide evidence of signal mimicking in stock repurchases in international data that is influenced by market, ownership, legal, and financial reporting characteristics of countries.     

What do dividends tell us about earnings quality?

Over the past 30 years, there have been significant changes in the distribution of earnings—cross-sectional variation has increased, with increasing left skewness—as well as in corporate payout policy, with many fewer firms paying dividends and the emergence of stock repurchases. We investigate whether the informativeness of payout policy with respect to earnings quality changes over this period. We find that the reported earnings of dividend-paying firms are more persistent than those of other firms and that this relation is remarkably stable over time. We also find that dividend payers are less likely to report losses and those losses that they do report tend to be transitory losses driven by special items. These results do not hold as strongly for stock repurchases, consistent with them representing less of a commitment than dividends.     

美国货币政策推升了新兴市场国家非金融企业杠杆率吗？

全球金融危机后,美国量化宽松货币政策的实施导致全球流动性异常充裕,对新兴市场国家非金融企业外部融资环境造成显著影响。本文运用28个新兴市场国家2003-2015年非金融类上市企业财务数据和美国影子利率数据对美国货币政策调整与新兴市场国家非金融企业杠杆率变动之间的关系进行了实证分析。结果显示,美国影子利率与新兴市场国家非金融企业杠杆率变动之间存在显著负相关关系,即美国影子利率的降低会促使新兴市场国家非金融企业杠杆率出现更大幅度的上涨。进一步地,这一影响在融资约束程度较高的企业、外部融资依赖度较高的行业以及资本账户开放程度较高但汇率弹性僵化的国家表现得更为显著。上述发现意味着新兴市场国家在调控企业部门杠杆率的过程中,除要考虑国内因素外,也应高度重视美国货币政策的变化。     

VALUATION EFFECTS OF OPEN MARKET STOCK REPURCHASES FOR FINANCIALLY WEAK FIRMS

We test the proposition that announcements of open market stock repurchases improve the flow of positive information regarding the firm's prospects, particularly for financially weak firms. For financially strong firms with already good prospects for cash flows, the role of stock repurchases is less important. We provide evidence for an inverse relationship between financial risk, measured by bond rating, and the magnitude of stock repurchase-induced abnormal returns. Results also suggest that the value of information implied by announcements of open market repurchases about increases in cash flows and leverage, is more important for financially weak firms than for financially strong firms.     

Macroeconomic cycles and the stock market’s reaction to monetary policy

This paper examines cyclical variation in the effect of Fed policy on the stock market. We find a much stronger response of stock returns to unexpected changes in the federal funds target rate in recession and in tight credit market conditions. Using firm-level data, we also show that firms that face financial constraints are more affected by monetary shocks in tight credit conditions than the relatively unconstrained firms. Overall, the results are consistent with the credit channel of monetary policy transmission.     

Empirical investigation of changes in policy uncertainty on stock returns—Evidence from China’s market

This study finds evidence that a rise in economic policy uncertainty (EPU) leads to a decline in stock returns in Chinese market; however, a positive coefficient was observed in the lagged EPU as stock prices rebound. This phenomenon also holds true for a rise in uncertainty innovations in fiscal policy, monetary policy, trade policy and global policy. The evidence leads to conclude that policy uncertainty premiums should be priced into China’s stock prices. An escalation of U.S. policy uncertainty has a significantly harmful effect on Chinese stocks regardless of whether firms are stated own or listed on U.S. market.     

Dividends versus Share Repurchases Evidence from Canada: 1985–2003

This paper provides out-of-sample evidence on the payout policy in Canada during the 1985–2003 period. First, we show that the proportion of nonfinancial firms paying dividends has decreased, while the proportion initiating repurchase programs has increased. We also show that Canadian firms paying dividends and repurchasing shares are extremely concentrated. Second, we focus on the factors that could affect the choice between repurchases and dividends. We find that dividends and repurchases are used by different types of firms. While we do not confirm the financial flexibility hypothesis, our results are consistent with the substitution hypothesis after controlling for selection bias and endogeneity.     

Monetary Policy and Price Responsiveness to Aggregate Shocks under Rational Inattention

This paper studies a general equilibrium model that is consistent with recent empirical evidence showing that the U.S. price level and inflation are much more responsive to aggregate technology shocks than to monetary policy shocks. Specifically, we show that the fact that aggregate technology shocks are more volatile than monetary policy shocks induces firms to pay more attention to the former than to the latter. However, most important, this work adds to the literature by analytically showing how monetary policy feedback rules affect the incentives faced by firms in allocating attention. A policy rule responding more actively to inflation fluctuations induces firms to pay relatively more attention to more volatile shocks, helping to rationalize the observed behavior of prices in response to technology and monetary policy shocks.     

What drives U.S. financial sector volatility? A Bayesian model averaging perspective

We investigate the driving forces behind the quarterly stock price volatility of firms in the U.S. financial sector over the period from 1990 to 2017. The driving forces represent a set of 28 economic indicators that are routinely used to detect financial instability and crises and correspond to the development of the financial, monetary, real, trade and fiscal sector as well as to the development of the bond and equity markets. The dimensionality and model choice uncertainty are addressed using Bayesian model averaging, which led to the identification of only seven variables that tend to systematically drive the stock price volatility of financial firms in the U.S.: housing prices, short-term interest rates, net national savings, default yield spread, and three credit market variables. We also confirm that our results are not an artefact of volatility associated with market downturns (for negative semi-volatility), as the results are similar even when market volatility is associated with market upsurge (positive semi-volatility). Given the identified drivers, our results provide supporting empirical evidence that dampening credit cycles might lead to decreased volatility in the financial sector.     

International spillover effects of unconventional monetary policies of major central banks

This study examines the effects of unconventional monetary policies (UMPs) by the major central banks, namely the Bank of England (BOE), Bank of Japan (BOJ), European Central Bank (ECB) and the Federal Reserve (Fed), on the international financial markets, taking global spillovers and monetary policy interaction into account. To this end, we applied the Global Vector Autoregressive (GVAR) model to 35 countries/economies and one region for the period from March 2009 to July 2019. In addition, we accommodated the smooth transition to the GVAR to consider possible structural changes in the effects of UMPs and monetary policy interaction. Our results indicate the importance of capturing structural changes, showing the remarkable difference between the beginning and end of the sample. For example, we found clear evidence of monetary policy coordination after the global financial crisis and less evidence of policy interaction in the recent period. Also, our results suggest that generally, the UMPs of the major central banks had stronger effects on both domestic and international bond markets in the earlier period. In contrast, the global equity markets responded more positively to the UMPs in the recent period, although there was no noticeable difference in the responses of domestic equity markets throughout the sample.     

Emerging market corporate leverage and global financial conditions

This paper explores how global financial conditions influence corporate leverage growth in emerging markets (EMs). Using a sample of 800,000 listed and non-listed firms across 28 EMs, we find that accommodative global financial conditions—initially proxied with a measure of U.S. monetary policy—are associated with faster leverage growth. The impact is more pronounced for financially constrained firms, such as small- and medium-sized enterprises (SMEs), and for EMs whose domestic monetary policy is more aligned with that of the United States. The findings suggest that global financial conditions affect EM firms' leverage growth by influencing domestic interest rates and by relaxing corporate borrowing constraints. Finally, leverage increases disproportionately more for firms that are either relatively less profitable or less solvent when global financial conditions become looser.     

货币传导异质性与实体经济流动性配置的“马太效应”

货币政策支持实体经济高质量发展的关键在于疏通货币政策传导机制,引导流动性进入重点领域和薄弱环节,因此货币资金的配置效率至关重要。本文基于交互效应面板分位数回归,测度货币政策对实体企业流动性的异质性效应。研究发现:在样本期内,实体经济流动性配置陷入了资金越充裕的企业越易于获得融资,越易于获得融资的企业资金越充裕的窘境。这种流动性配置的“马太效应”具体表现为,货币政策对尾部企业的支持力度不及头部企业的一半;虚拟经济对尾部企业的“分流效应”高达头部企业的3倍,从而强化了流动性配置的失衡。因此,当前密集出台的一系列普惠政策有助于提升流动性配置效率,进一步完善调控模式的关键在于健全现代化金融体系,增强货币政策的靶向性和针对性。     

An empirical application of the EVA® framework to business cycles

Following financial concepts like duration and economic value added (EVA®) we estimate the impact of interest rate movements on firms that are more and less roundabout. We find that firms that are more roundabout, that is, work with expected cash-flows with higher duration, are more sensitive to interest rate movements. To the extent that monetary policy is able to move the discount rate used by investors, monetary policy changes the relative present value of any investment project and therefore affects resource allocation. We show evidence that this effect is present in the U.S. in the years prior to the subprime crisis.
