未预期货币政策冲击与股票价格

货币政策影响股票价格的理论机制清晰确凿,实证检验的主要挑战是资本市场对货币政策冲击可能存在事先预期。基于货币政策公告后的国债收益率变动,文章识别了未被市场充分预期的货币政策冲击,并实证考察了 2000 年以来历次法定存款准备金率调整和贷款基准利率调整,发现未预期货币政策冲击对股票市场价格产生显著影响,1% 的未预期“降准”会引起上证指数和深证综指上涨 1.39% 和 1.415%,1% 的未预期“降息”会引起上证指数和深证综指上涨 0.662% 和 1.01%。     

Macroeconomic Variables and Stock Prices in Malaysia: An Empirical Analysis

The article investigates the dynamic interactions between seven macroeconomic variables and the stock prices for an emerging market, Malaysia, using cointegration and Granger causality tests. The results strongly suggest informational inefficiency in the Malaysian market. The bivariate analysis suggests cointegration between the stock prices and three macroeconomic variables – consumer prices, credit aggregates and official reserves. From bivariate error-correction models, we note the reactions of the stock prices to deviations from the long run equilibrium. These results are further strengthened when we extend the analysis to multivariate settings. We also note some evidence that the stock prices are Granger-caused by changes in the official reserves and exchange rates in the short run.     

The Impact of Macroeconomic Announcements on Stock Prices: In Search of State Dependence

Federal bureaus make regularly scheduled public announcements of macroeconomic variables such as employment, the price level, and the money stock. Recently, several studies claim to establish an empirical relationship between the impact of these announcements on financial markets and the state of the business cycle. The present article estimates the impact of several announcement variables on daily closing values of the Standard and Poor's (S&P) 500. Contrary to previous studies, this study finds no significant evidence that the marginal effects of announcements vary with the state of the economy.     

International Monetary Regimes and Incidence and Transmission of Macroeconomic Shocks: Evidence from the Bretton Woods and Modern Floating Periods

This paper investigates the relationship between international monetary regimes and incidence and transmission of macroeconomic shocks within the context of an open-economy macro model. Empirical results confirm monetary interdependence and lower incidence of monetary discretion under fixed exchange rates. The average magnitude and dispersion of supply shocks in Bretton Woods and the subsequent float is comparable; however, the average magnitude and dispersion of real demand shocks under Bretton Woods seems higher. Overall, the international monetary regime may pose important constraints to policymakers in open economies.     

股票价格与汇率之间的动态关系——基于中国市场的经验分析

本文以利差为外生变量,基于向量自回归多元EGARCH模型和日数据,对我国股价与汇率之闻的动态关系进行了实证研究和深入分析.研究发现:在价格溢出方面,只存在外汇市场到股票市场短期单向引导关系,但利差对股价和汇率均存在价格溢出效应;在波动溢出方面,股票市场对外汇市场存在非对称的波动溢出效应,而外汇市场对股票市场只存在对称的波动溢出效应,利差的变化对股票市场和外汇市场都不存在波动溢出效应;与国内相关研究结论不同的是,我们没有发现股价与汇率之间存在长期均衡关系.     

资本市场开放能够提高股票价格稳定性吗?:基于沪港通的经验证据

基于2012年11月至2016年11月上海证券市场的月度面板数据,文章通过双重差分固定效应模型,分别从不同期间、不同市场开放程度入手,研究沪港通对股票价格稳定性的影响。研究发现,沪港通的实施有效降低了标的股票的整体波动性,波动性在短期的增加只是一种暂时性的现象,沪港通的实施通过扩大股票投资者基础、优化市场投资者结构从而对股价稳定性带来积极影响。随着市场开放程度的增加,沪港通也会对股票的极端波动产生影响,降低公司股价跳升风险,有利于缓解A股市场的投机氛围,但同时也增加了公司股价崩盘风险,带来市场不稳定因素。沪港通实施后公司股票的崩盘风险与中国证券市场薄弱的信息披露环境有关,那些信息披露环境差的公司股票的崩盘风险显著增加。     

Policy Shocks and Macroeconomic Fluctuations in a Two‐country Dynamic Stochastic General Equilibrium Model: Evidence from China*

In this paper, we construct a two‐country dynamic stochastic general equilibrium model to investigate the sources of business cycles in China and the contributions of policy shocks in economic fluctuations. The empirical results from Bayesian estimation show that, apart from the traditional supply and demand shocks, monetary and fiscal policy shocks also play important roles in determining China's economic fluctuations. In addition, we find significant feedback effects between monetary and fiscal policies in China, indicating that policy coordination is an important feature of China's monetary and fiscal policies. Overall, these results not only shed new light on the policy factors behind China's economic fluctuations, but also provide new evidence that is helpful for understanding the policy transmission mechanisms in China.     

Foreign and Domestic Shocks: Macroeconomic Responses of ASEAN-3 Countries

Abstract

The study provides new empirical evidence on the relative importance of foreign and domestic shocks on selected ASEAN-3 (Malaysia, Indonesia, and Thailand) macroeconomic variables. Three structural vector auto regression models are estimated for each country. The focal point is given on the formulation of the sources of foreign factors. The first model uses trade-weighted foreign variables of both US and Japan to represent the foreign factors. The other two models use US and Japan by themselves, respectively, to represent the foreign factors. Two important results are emerged. First, foreign sectors play an important role in influencing macroeconomic variables of each of the ASEAN-3 country, especially in the medium and the long-run horizon. Second, most of the time, the Japanese factors are more dominant than the US factors in influencing domestic output and inflation for each of the ASEAN-3 countries.     

Macroeconomic effects of uncertainty shocks: Evidence from Korea

This paper proposes a new measure of economic policy uncertainty (EPU) for Korea by fine-tuning the keywords and exploiting information drawn from a wide variety of local newspapers. The uniqueness of our new EPU index lies mainly in the fact that it uses a set of keywords that correspond much more closely to actual language use and better reflect the economic environment of Korea, which is classified as a small open economy. After shocks to EPU being identified, we employ these shocks to estimate the impulse responses using local projections. Unlike the existing measure, our results show that shocks to EPU lead to a significant decline in macroeconomic aggregates such as output, consumption, investment, and employment. Thus our results suggest a refinement of the EPU index in general for other countries accordingly. We also develop policy-specific uncertainty indices and show that they capture important historical events related to the corresponding policies, such as monetary and fiscal measures.     

Macroeconomic implications of population aging: Evidence from Japan

Population aging is an important feature of Japan’s economy, which since 2006 has become a super-aged society. Changes in the age distribution of the population have important macroeconomic implications. Using annual data for 1960–2015, this study tests whether population age shares have long run influences on domestic saving, domestic investment, real GDP, inflation, the fiscal balance, and the current account balance. Cointegration is found between each macroeconomic variable and the demographic variables, which is a key finding of the analysis. The main empirical findings from the long-run cointegrating equations are that the effects of demographic change on the macroeconomic variables are statistically significant and quite strong. Alternative variants of the United Nation’s population projections provide further evidence of the importance of the demographic changes for Japan’s macroeconomic future. This study finds that future trends of key macroeconomic variables are not monotonic, but rather that long swings in the demographic factors produce a mixture of moderate growth periods and episodes of GDP stagnation.     

Macroeconomic Effects of Inflationary Shocks with Durable and Non-Durable Consumption

In this paper we show that inflation, both in the short and long run, negatively affects durable and non-durable consumption and output, and positively influences the current account balance. In particular, the impact of inflation is more pronounced on durable relative to non-durable goods. Using quarterly data from Canada, the UK and the USA, we demonstrate that these findings are consistent and robust across different econometric specifications. An open economy model with durable and non-durable consumption, households with labor/leisure choice and money introduced through cash-in-advance (CIA) constraint on consumption expenditure alone could meaningfully explain these empirical observations. Our empirical findings of non-neutral and negative effects of inflation on real growth are significant for many economic models in the asset pricing literature that support a negative co-movement of stock prices and expected inflation. Moreover, such positive inflation premium in our model could provide economic explanation for a positive slope of the nominal term structure in the data.     

Asset Prices, Monetary Policy and Macroeconomic Stability

This article discusses the role of asset prices in the conduct of monetary policy when the ultimate goal is to maintain price stability and limit fluctuations in real income. It is argued that judicious interpretation of asset price movements can provide information about the risks of future macroeconomic imbalances, and that this information should be utilized in monetary policy decisions. Simulations results from both theoretical and empirical models support the conceptual argument. It is stressed that policy reactions to asset prices must not follow a mechanical rule, since the appropriate response depends on the underlying shock.     

Exchange Rates and Prices under Processing Trade: A Macroeconomic Analysis

In an economy dominated by labor-intensive processing trade, such as China, real exchange rate appreciation can possibly increase rather than decrease net exports. As the import content of processed exports (a proxy for dependence on processing trade) increases in its continuum, the stable equilibrium for the exchange rate and price level eventually yields to a saddle-point equilibrium. Unless the initial inflation (or deflation) rate is uniquely moderate at a given exchange rate, either the depreciation-inflation spiral or the appreciation-deflation spiral can dominate. Monetary and fiscal policies can help a processing-trade dependent country in structural transition from excessive engagement in processing trade (the saddle-point equilibrium) to a more sustainable and balanced trade structure.     

The Role of Economic Shocks on Health: Evidence from German Reunification

Sudden economic shocks impact the everyday lives of people from one day to the next. A number of studies have examined the association between economic fluctuations and health; however, no consensus on the nature of this relationship has been established. By exploiting the dramatic economic fluctuations following the German Reunification of 1990, which included a sudden change from a socialist to a capitalist system in East Germany, this study examines the association between broad negative economic shocks and health. The article finds that increases in state unemployment rates are associated with large and statistically significant declines in health outcomes. Estimates are stronger for people who became unemployed shortly after reunification, for low‐income individuals, and for East Germans, a group confronted with larger economic fluctuations. When examining potential mechanisms that could explain the observed health deteriorations, the study finds significant reductions in exercise frequency and increases in economic uncertainty and overall stress.     

Business Cycle Fluctuations,Large Macroeconomic Shocks,and Development Aid

We examine the cyclical properties of development aid using bilateral data for 22 donors and 113 recipients during 1970–2005. We find that bilateral aid flows are on average procyclical with respect to the business cycle in both donor and recipient countries. While aid outlays contract sharply during severe downturns in donor countries, they rise steeply when aid-receiving countries experience large adverse shocks. Our findings suggest that development aid may play an important cushioning role in developing countries, but only during times of severe macroeconomic stress. Our results are robust to alternate definitions of aid flows, specifications, and estimation techniques.     

Incentive and Dilution Effects of Employee Stock Bonuses and Stock Options: Evidence from Taiwan

Employee stock bonuses (ESBs) and employee stock options (ESOs) are the means for high-technology companies in Taiwan to reward their employees. This research connects the Ohlson (1995 Ohlson, JA. 1995. Earnings, book values, and dividends in equity valuation. Contemporary Accounting Research, 11: 661–687. [Crossref] , [Google Scholar]) model and Linear Structural Relations (LISREL) model to investigate these effects of ESBs and ESOs, respectively, for a sample of high-technology companies in Taiwan. I generate two empirical generalizations. (1) The incentive effects of ESBs are significantly associated with performance, thus enhancing firm value; in addition, the incentive effects of ESBs are greater than the dilution effects. (2) The incentive effects of ESOs are also significantly associated with performance, whereas the dilution effects of ESOs are insignificant. Although evidence supports the incentive effects of providing ESOs and ESBs, it is debatable whether ESOs and ESBs dilute shareholders’ equity.
