The VIX, the stock market option-based implied volatility, strongly co-moves with measures of the monetary policy stance. When decomposing the VIX into two components, a proxy for risk aversion and expected stock market volatility (“uncertainty”), we find that a lax monetary policy decreases both risk aversion and uncertainty, with the former effect being stronger. The result holds in a structural vector autoregressive framework, controlling for business cycle movements and using a variety of identification schemes for the vector autoregression in general and monetary policy shocks in particular. The effect of monetary policy on risk aversion is also apparent in regressions using high frequency data.  相似文献

A method is developed which for a given objects by variables data matrix estimates weighted inter-object distances that are optimally suited for either an ultrametric or an additive tree representation. The effectiveness of the method is demonstrated on two synthetic data sets having a known tree structure and on one real data set. In the final section, some possible extensions of the present method are discussed.  相似文献

Identifying Organizational Subcultures: An Empirical Approach   总被引:7,自引:0,他引:7  
Organizations have cultures, but parts of organizations may have distinct subcultures. The question of what is the proper level for a cultural analysis of an organization is generally handled intuitively. The organizational culture of a large Danish insurance company (3,400 employees) was measured, based on employees' answers to 18 key questions about work practices. Subsequently, scores were determined separately for 131 work groups, and these were subjected to a hierarchical cluster analysis, which produced a dendrogram. The dendrogram showed that within the company there were three distinct subcultures: a professional subculture, an administrative subculture, and a customer interface subculture. These fit a theoretical prediction by Jones (1983); the cultural rifts between the subcultures could be readily recognized in the company's practice, and had tangible consequences.  相似文献

We decompose the squared VIX index, derived from US S&P500 options prices, into the conditional variance of stock returns and the equity variance premium. We evaluate a plethora of state-of-the-art volatility forecasting models to produce an accurate measure of the conditional variance. We then examine the predictive power of the VIX and its two components for stock market returns, economic activity and financial instability. The variance premium predicts stock returns while the conditional stock market variance predicts economic activity and has a relatively higher predictive power for financial instability than does the variance premium.  相似文献

The ‘Guiding Principles on Business and Human Rights’ (Principles) that provide guidance for the implementation of the United Nations’ ‘Protect, Respect and Remedy’ framework (Framework) will probably succeed in making human rights matters more customary in corporate management procedures. They are likely to contribute to higher levels of accountability and awareness within corporations in respect of the negative impact of business activities on human rights. However, we identify tensions between the idea that the respect of human rights is a perfect moral duty for corporations and the Principle’s ‘human rights due diligence’ requirement. We argue that the effectiveness of the ‘human rights due diligence’ is in many respects dependent upon the moral commitment of corporations. The Principles leave room for an instrumental or strategic implementation of due diligence, which in some cases could result in a depreciation of the fundamental norms they seek to promote. We reveal some limits of pragmatic approaches to coping with business-related human rights abuses. As these limits become more apparent, not only does the case for further progress in international and extraterritorial human rights law become more compelling, but so too does the argument for a more forceful discussion on the moral foundations of human rights duties for corporations.  相似文献

Local Return Factors and Turnover in Emerging Stock Markets   总被引:11,自引:0,他引:11  
The factors that drive cross-sectional differences in expected stock returns in emerging equity markets are qualitatively similar to those that have been documented for developed markets. Emerging market stocks exhibit momentum, small stocks outperform large stocks, and value stocks outperform growth stocks. There is no evidence that high beta stocks outperform low beta stocks. A Bayesian analysis of the return premiums shows that the combined evidence of developed and emerging markets strongly favors the hypothesis that similar return factors are present in markets around the world. Finally, there exists a strong cross-sectional correlation between the return factors and share turnover.  相似文献

This paper examines the ability of beta and size to explain cross-sectional variation in average returns in 12 European countries. We find that average stock returns are positively related to beta and negatively related to firm size. The beta premium is in part due to the fact that high beta countries outperform low beta countries. Within countries high beta stocks outperform low beta stocks only in January, not in other months. We reject the hypothesis that differences in average returns on size- and beta-sorted portfolios can be explained by market risk and exposure to the excess return of small over large stocks (SMB). Consistent with recent US evidence, we find that after controlling for size, there is no association between average returns and exposure to SMB.  相似文献
