We find that passive intensity (PI), measured by the passive‐linked share of total stock market trading volume, is strongly related to the overall pattern of stock price movements. A one‐standard‐deviation increase in PI is associated with an 8% higher price synchronicity. We further investigate the channels through which this relation is established by separately analyzing its impact on aggregate systematic and idiosyncratic volatility of stock returns. PI has a positive effect on systematic volatility and a negative impact on firm‐specific volatility. Consistent with the effect of passive trading on price dynamics, we find evidence that PI is negatively associated with mutual funds alpha dissimilarity. After controlling for market and idiosyncratic volatility, a one‐standard‐deviation increase in PI corresponds to a 0.20% decrease in fund dissimilarity. Our findings are robust after controlling for various macro and corporate factors known to affect systematic or firm‐specific volatility. 相似文献

We de-compose the S&P Goldman Sachs Commodity Index into its underlying commodity sub-categories and develop a modified conditional value at risk (CVaR) metric to examine downside risk linked to economic periods which are classified by their GDP growth as green, yellow, orange and red. We term this new metric economic CVaR (ECVaR). We found significant differences in the relative ECVaR rankings of different commodities over our different economic cycles. 相似文献

In this article, we investigate scale economies in Norwegian electricity distribution companies using a quantile regression approach. To the best of our knowledge, this is the first attempt to apply this estimation technique when analysing scale economies. We estimate the cost elasticities of the two output components: network length and number of customers, to calculate returns to scale. Our results show large potential of scale economies, particularly for the smallest companies. We also find that returns to scale is increasing over time. These findings have important implications for policymakers when they are deciding the structure of the industry in the future. 相似文献

This study examines the roles of interdependence and policy variations across firms in the causality between bank size and profitability in Nigeria, using second-generation estimators and the Dumitrescu–Hurlin panel Granger non-causality test. The findings support different business strategies and policy variances across banks. Causality is found non-existent in the cases of 11 banks. A unidirectional causality from size to profitability is established in two banks while evidence of a unidirectional causality is established from profitability to bank size in the other two banks. This study concludes that cross-sectional dependence and policy variations across firms matter in the bank size–profitability nexus. 相似文献

We propose that the positive effect of coming-of-age songs on ad effectiveness arises from a mediation process where the music-evoked interpersonal memories of growing up stored in the brain and their accompanying emotions inevitably play a role, but not so straightforwardly as previously suggested. Rather, their effects work through the heightened familiarity of and peaked preferences for coming-of-age songs. We also propose that these sequentially mediated effects are moderated by viewers' developmental attachment styles. We test and find support for these propositions in three multimethod studies with more than 1200 participants born between the 40s and the mid-70s and almost 60 popular songs released between the 60s and the 2010s. We discuss the implications of our findings, namely for age-segmented video ads, and suggest future research directions. 相似文献

We formulate and solve a multi-player stochastic differential game between financial agents who seek to cost-efficiently liquidate their position in a risky asset in the presence of jointly aggregated transient price impact, along with taking into account a common general price predicting signal. The unique Nash-equilibrium strategies reveal how each agent's liquidation policy adjusts the predictive trading signal to the aggregated transient price impact induced by all other agents. This unfolds a quantitative relation between trading signals and the order flow in crowded markets. We also formulate and solve the corresponding mean field game in the limit of infinitely many agents. We prove that the equilibrium trading speed and the value function of an agent in the finite N-player game converges to the corresponding trading speed and value function in the mean field game at rate . In addition, we prove that the mean field optimal strategy provides an approximate Nash-equilibrium for the finite-player game. 相似文献

This study proposes a new measure of the tradability of 120+ commodities based on price dispersion. This approach is used to construct price indices of tradables and non-tradables for 150+ countries. The expenditure share of tradables is lower for richer countries, while the relative price of non-tradables, which plays an important role in the determination of real exchange rates, is higher. Secondly, a common-factor approach (based on principal components) is introduced to compress the large volume of information on prices and quantities consumed globally. We find that cross-commodity correlations are higher for prices than for consumption. In addition, income is responsible for most of the variation in the first principal component of consumption but explains less of the first price component. This suggests consumption are driven primarily by domestic factors, while prices are determined by factors outside the country, along the lines of the Purchasing Power Parity theory. 相似文献

Extant literature has extensively explored microcredit's impacts, confirming its essential role in poverty alleviation. However, most studies focus on poverty measures that exclusively emphasize current poverty status without adequately addressing the potential of falling into or remaining in poverty. Furthermore, the role of credit services in helping the poor in rural areas appears to be underexamined in the literature. To address this knowledge gap, this study investigates whether rural microcredit can reduce household vulnerability to poverty. A theoretical framework is developed to capture the mechanism by which microcredit borrowing has a vital role in household businesses and impacts the probability of being poor in the future. The Vietnam Access to Resources Household Survey data set from 2008 to 2016 is used to explore this issue. The findings indicate that rural Vietnam's access to microcredit significantly reduces vulnerability to poverty. Moreover, better-off households are seemingly the most effective at using microcredit, whereas the opposite is found among worse-off households. These results are found to be robust using the propensity score matching method. 相似文献

We examine the environmental impact of the staggered adoption of universal demand laws by 23 U.S. states between 1989 and 2005. Universal demand laws impede derivative lawsuits and thus undermine shareholder oversight of corporate environmental performance. We find that weakened litigation rights for shareholders are positively associated with the release of toxic chemicals by firms. The effect is stronger for firms with weak governance, and environmental mismanagement by firms after the passage of the laws lead to poorer financial performance. Overall, our findings imply that derivative lawsuits by shareholders are not frivolous, as is often asserted. Rather, they act as an effective mechanism of corporate governance. 相似文献
