This article studies the co-movement of the levels, as well as of the volatilities, of the Chinese and U.S. aggregate stock returns in 1995–2014, focusing on the impact of the liberalization of Chinese stock market from 2005. The volatilities of the two returns appear to have started to co-move in 2006. To understand the co-movement, we use the GARCH BEKK method. The result suggests that before 2006, the evolution of the U.S. returns had a tendency to affect the Chinese returns in level and volatility. However, after 2006, the two returns affected each other in a more complex way.  相似文献

This article combined both cross-sectional and time-series longitudinal analysis to identify that factor anomalies are driven by either over-reaction or under-reaction. The basic principle is, first, use a factor to form 10 portfolios in the t quarter, then observe the average prices and returns of the 10 portfolios for the previous four quarters and for the following four quarters as well. Samples in this study contain all stocks listed in the US from 1990 to 2010. The empirical evidence shows that the reason for the abnormal returns of value (book-to-price ratios, earnings-to-price ratios, sales-to-price ratios), scale and liquidity factors is over-reaction. Meanwhile, the reason for the abnormal returns of growth factors (return on equity, return on assets and revenue growth rate) is under-reaction. The results provide significant policy implications. The anomaly returns of the value, scale and liquidity factors last longer and are more appropriate to be employed for long-run investment while the growth factors are better suited for short-run investment. Furthermore, a more profitable stock-selection strategy can be formed by simultaneously considering the above two types of factors to capture both of these two sources of anomaly returns.  相似文献

This paper draws attention to the innovative but neglected workof Hans Singer on the dynamics of unemployment. Influenced byKeynes, in the late 1930s Singer enquired into the relationshipbetween the inflow into unemployment—resulting primarilyfrom (involuntary) separations from employment—and thesize of the resultant fluctuations in the level of unemployment.His focus was on the determinants of the severity—measuredin terms of how far unemployment rises—of recessions.We illustrate his approach by looking at quarterly data forthe claimant count and its associated inflow and outflow inthe UK over the period 1989–2003, a period which includesone major recession episode. In addition to drawing attentionto Singer's ideas, the paper also extends his model by takinginto account recent empirical evidence on the behaviour of oneof the key variables in his model. We argue that, with thisextension, Singer's elegant and parsimonious model of unemploymentdynamics is a useful complement to Keynes's ideas on the fluctuationsin aggregate demand and output, and is of contemporary relevance.  相似文献

本文针对当前中国所面临的资本流动新格局(即大量非FDI流入) ,分析了国际资本流动引起宏观不稳定的机制,以及通过对冲与资本管制方式应对资本流动冲击的局限。论文的核心是引入经济扭曲概念,建立了带扭曲因素的资本流动与宏观稳定模型,强调扭曲的存在会使波动加剧。因此,为应对资本流动新格局,政策当局需要尽快完善非FDI监控体系、矫正各种经济扭曲,并促使宏观调控模式由数量型向价格型转变  相似文献

美国量化宽松货币政策影响及中国对策   总被引:10,自引:0,他引:10  
随着金融危机的不断蔓延和影响的逐渐深化,美国在采取第一轮和第二轮量化宽松货币政策失效后,还可能采取第三轮量化宽松货币政策来稳定和刺激经济。此种极端货币政策引发多米诺骨牌效应,并将对中国经济产生深远影响。对此,文章从量化宽松货币政策产生的机理出发,在着重分析美国量化宽松货币政策对中国经济可能造成影响的基础上,提出中国所应采取的应对策略,以减缓量化宽松货币政策对中国经济可能产生的不利影响。  相似文献

Routing games are studied to understand the impact of individual users' decisions on network efficiency. Most prior work on efficiency in routing games uses a simplified model where all flows exist simultaneously, and users care about either their maximum delay or their total delay. Both these measures are surrogates for measuring how long it takes to get all of a user's traffic through the network. We attempt a more direct study of network efficiency by examining routing games in a flow over time model. Flows over time are commonly used in transportation research. We show that in this model, by reducing network capacity judiciously, the network owner can ensure that the equilibrium is no worse than a small constant times the optimal in the original network, for two natural measures of optimality. These are the first upper bounds on the price of anarchy in this model for general networks.  相似文献

在开放经济的"三元冲突"中,中国选择了固定汇率,较严格的资本管制和较大的货币政策独立性,即用少量货币政策独立性的丧失换取有限度的资本流动.但在这种组合下,随着我国资本流动规模的扩大,货币政策独立性也将进一步丧失.对于中国,货币政策的自主权至关重要,除非有能力继续维持更严格的资本管制,我国必须逐步扩大汇率的浮动区间.  相似文献

The literature on FDI shows that there exists a wage premium that multinational enterprises (MNEs) pay to local workers and link this to a technology spillover argument. The MNEs pay higher wages to prevent worker turnovers and technology leakages. Literature relates the wage premium aspect of FDI using worker mobility data and uses worker turnovers and the technology spillover argument. We relate stock options in the FDI context of worker mobility and find in a simplified framework that the turnover of workers would depend on the relative payments of stock options.  相似文献

This paper constitutes - to our best knowledge - the first econometric analysis on stock market effects of the EU Emission Trading Scheme (EU ETS). Our results suggest that EU Emission Allowance (EUA) price developments matter to the stock performance of electricity firms: EUA price changes and stock returns of the most important European electricity corporations are shown to be positively related. This effect does not work asymmetrically, so that stock markets do not seem to react differently to EUA appreciations in comparison to depreciations. The carbon market effect is shown to be both time- and country-specific: It is particularly strong for the period of EUA market shock in early 2006, and differs with respect to the countries where the electricity corporations analysed are headquartered. Stock market reactions to EUA volatility could not be shown.  相似文献

This paper investigates the role of stock characteristics and investor type in market myopia. Using the Generalized Method of Moments (GMM) to control for endogeneity, we obtain evidence indicating that market myopia is greater among stocks that are relatively hard-to-value and hard-to-arbitrage, and find this conclusion to be robust to the choice of proxy for these characteristics. We also obtain a significantly negative relationship between institutional ownership and market myopia, due to the former acting as informed traders who exploit mispricing created by individual traders. It is important to note that the impact of their role becomes significant only when they have a sizeable share in firm ownership, as is the case of UK mutual funds and pension funds and Spanish banks.  相似文献

Currently, there exists relatively little research investigating the long-term association between stock and direct real estate markets. Using appropriate transaction-based property indices, this study focuses on the relationship between stock and direct real estate markets in nine Asian countries from the period 1980 to 2012 through both linear and nonlinear cointegration techniques. We find empirical evidence of linear cointegration of stock and property markets in Taiwan, fractional cointegration in Singapore and Hong Kong and no evidence of cointegration in China, Japan, Thailand, Malaysia, Indonesia and South Korea. It is concluded that segmentation of property markets from stock markets does not appear to be linked to the differences in the maturity of national financial markets and that the differing degrees of integration across Asia may instead be reflective of a range of factors impacting upon the underlying economic structures in each country.  相似文献

Previous studies have provided evidence that investors have gambling propensity in the stock market and exhibit a preference for lottery-type stocks. In this study, we use high total skewness and high maximum daily return (MAX) to measure lottery-type stocks and examine whether investors do exhibit distinct herding pattern in these stock types. Empirical results show that investors display stronger herding among lottery-type stocks, thereby indicating that such stocks induce correlated behaviour with the investors. In addition, we find that stocks with the highest skewness exhibit stronger herding under upmarkets, whereas stocks with the lowest skewness display stronger herding under downmarkets. Regarding the highest MAX portfolio, no significant herding asymmetry is seen between upmarket and downmarket. The results reported in this article demonstrate that comovement in stock returns may be partly attributed to the nonstandard preferences of investors in the stock market.  相似文献

This paper presents empirical evidence suggesting that the transition economies have tended to experience capital flight during periods of macroeconomic instability, such as high inflation and sharply declining output. The timing of these outflows, however, has differed somewhat across countries. Poland and Czechoslovakia experienced significant capital flight early in the transition process, but as reforms have progressed, capital outflows have slowed. By contrast, Russia registered a relatively steady flow of capital flight from 1991-94, with cumulative outflows totalling about $40 billion. Finally, capital flight from Hungary has been subdued, paralleling the gradual course of economic reforms and the country's comparative political stability.  相似文献

In this article, we provide statistical evidence around jumps affecting commodity returns. Using nearly 20 years of daily data, we use Laurent, Lecourt, and Palm's (2011) methodology to jump extraction, and discuss various aspects of the estimated jump activity. On average across various commodity markets, we find a high number of days for which returns exhibit the presence of jumps, consistently with the intuition that commodities are affected by large price fluctuations. We emphasize that the post-jump average return depends on the commodity sector considered (e.g. agriculture, energy, or metals). We also show evidence of a jump-to-volatility channel for commodities (similar to the effect usually found for equities). Finally, we diagnose around 40 dates during which commodity indices, stocks, bonds and currencies `co-jump’, revealing a tail dependence between standard and alternative assets.  相似文献

分别计量分析了各省区市创业板上市公司的数量、总市值、总利润、平均市盈率与各省区市GDP总量和人均值的关系,发现创业板上市公司的数量、总市值的区域分布主要与各区域的GDP总量和人均值有较大的关系,而创业板上市公司总利润、平均市盈率与GDP总量和人均值的关系强度较弱。创业板上市公司的上市数量在各省区市之间的分配,可能主要不是依赖于各创业型公司的质量。有计划成为创业板上市公司的企业,若注册在GDP总量或人均值比较靠前的东部省份,其成功上市的概率更高。  相似文献

The main purpose of this paper is to explore how interactions of knowledge flows and knowledge stocks could shape firms’ innovative performance. Knowledge flows are measured on the grounds of human resource training practices while different levels and forms of knowledge stocks (i.e. educational attainment, exporting activity, and firm age) are considered. We make use of two-period panel probit regressions and a rich data survey of the 524 largest Greek manufacturing firms conducted in two waves (2011 and 2013). Our findings suggest that the beneficial effects of knowledge flows strengthen when knowledge stocks accumulated by employees’ education and firm age are low. When knowledge stocks are limited, knowledge flows can act as a bridge for product innovation. On the contrary, when knowledge stocks are high, higher investments in knowledge flows may lead to diminishing returns and, thus, to decreased innovation performance beyond a certain point.  相似文献
