We examine daily short selling of Nasdaq stocks to explore whether speculative short selling causes a significant portion of the weekend effect in returns. We identify a weekend effect in speculative short selling whereby it constitutes a larger percentage of trading volume on Mondays versus Fridays. We find an opposite effect in dealer short selling, consistent with market makers adding liquidity and stability. Our main finding is that speculative short selling does not explain an economically meaningful portion of the weekend effect in returns, even among the firms most that are most actively shorted. This finding contradicts some prior studies. 相似文献

Business ethics searches: A socioeconomic and demographic analysis of U.S. Google Trends in the context of the 2008 financial crisis 下载免费PDF全文
A socioeconomic and demographic analysis of U.S. Google Trends for queries about Business Ethics and Greed is proposed in the context of the 2008 financial crisis. The framework is grounded in the ethical decision‐making literature. Two models using micro and macro‐type variables are tested using GLM and GEE regression techniques. The frequency of these Google queries varies positively with the ratio of females, educational attainment, younger adult age, some measures of economic hardship or inequalities, and the lesser the weight of the finance industry represented in each State. The frequency of queries intensifies for these same socioeconomic and demographic categories, in the aftermath of the financial crisis. This article is the first to study the salience of business ethics as an issue in the empirical literature using a nationwide database. It also provides a first empirical study in the specialized literature on “ethics in a time of crisis”. This study lays a preliminary groundwork to identify pro‐ethical reform segments of the population, with practical use for financial regulatory agencies. 相似文献

We give a condition under which the componentwise stochastic integration with respect to a given R d -valued continuous local martingale coincides with the more general vector stochastic integration defined by Jacod (1979). We then provide a result on the equivalence between the vector and the component completeness of a financial market in a special case. 相似文献

In this paper, recent techniques of estimating implied information from derivatives markets are presented and applied empirically to the French derivatives market. We determine nonparametric implied volatility functions, state–price densities and historical densities from a high–frequency CAC 40 stock index option dataset. Moreover, we construct an estimator of the risk aversion function implied by the joint observation of the cross–section of option prices and time–series of underlying asset value. We report a decreasing implied volatility curve with the moneyness of the option. The estimated relative risk aversion functions are positive and globally consistent with the decreasing relative risk aversion assumption. 相似文献

While willingness to pay is a common concept to measure the benefit gained from a reduction in the probability of loss, it
is still questionable how it is linked to risk aversion and risk elimination behaviors, and how it is affected by the presence
of an exogenous source of risk. By focusing only on risks of small losses, this article sheds light on these three issues
and provides new results on the determinants of the willingness to pay.

The issue of whether public capital is productive has received a great deal of recent attention. Yet, empirical analyses of public capital productivity have been limited to a small sample of countries for which official capital stock estimates are available. Building on a new database that provides internationally comparable capital stock estimates, this paper estimates the dynamic effects of public capital using the vector autoregressive (VAR) methodology for a large set of OECD countries. The empirical results suggest that there is evidence for positive output effects of public capital in OECD countries, but hardly any evidence for positive employment effects.JEL Code: C32, E62, H54 相似文献

Strategic Choices at Entry and Relative Survival Advantage of Cooperatives versus Corporations in the US Bio‐Ethanol Industry, 1978‐2015 下载免费PDF全文
The sustainability of cooperatives versus corporations is hotly contested. We propose that strategic choices at entry can help to explain the endurance of these two governance modes. We hypothesize that cooperatives have a survival advantage if their major drawback – high coordination costs – is curbed by high levels of member engagement at founding. Our analysis of survival rates in the US bio‐ethanol industry shows that cooperatives outlive corporations (1) if investment size at founding is large (strong financial engagement), (2) if they enter de novo instead of de alio (strong product‐market engagement) and (3) if the cooperative venture has been carefully planned from the start (greenfield entry) instead of built upon the acquisition of an existing plant (strong venture‐building engagement). These findings caution against the view that a particular mode of governance is superior or inferior to another in all circumstances. 相似文献
