This article analyzes the illiquidity premium in the MILA. Using seven proxies for illiquidity, we find a positive and significant illiquidity premium for our sample. A microstructure bias-free portfolio weighting based on past returns is critical in our finding of an illiquidity premium, which is robust to several methodological changes in our portfolio simulations. We also document that the premium is present only in small and high book-to-market stocks. Nonetheless, when we control for size and distress effects, the difference and significance in risk-adjusted returns between portfolios of high and low illiquidity stocks remains.  相似文献

We analyse the evolution of mortality rates in Spain by age and gender between 1990 and 2018. We compare municipalities, ranked by socio‐economic status (SES) and grouped into bins of similar population size, to study changes not only in levels but also in inequality in mortality across the SES spectrum. We document large decreases in mortality rates throughout the period for all age groups, including children, even after 2000, and continuing after the Great Recession. These declines are stronger for boys and men, who had higher mortality rates to begin with. We find that inequality in mortality across municipalities was low among the young by 2018, while it was higher among adult men and older women. Inequality in fact increased over the period for older men. We explore the role of different causes of death and find that this increase in inequality is driven by stronger improvements in cancer‐related mortality among men living in richer areas. These improvements are not found among women, given their increases in mortality due to lung cancer.  相似文献

The present study analyzes the influence that perceived risk in online shopping has on the process of e‐commerce adoption by end consumers. With this aim, the Technology Acceptance Model is taken as a reference framework, proposing an Extended E‐Commerce Acceptance Model that includes the diverse constructs of perceived risk: financial, performance, social, time, psychological and privacy. Empirical evidence is obtained from two samples, one is composed by Internet users with no experience in web shopping and the other is formed by online buyers. The results obtained confirm that the intention to shop through the Internet is positively influenced by general attitude toward the system and negatively influenced by the risk associated with the Web. Regarding the importance of the risk dimensions considered in the study, the economic and performance facets are the ones that have a greater influence on e‐commerce adoption, while social and time dimensions are the less relevant.  相似文献

This paper brings together research on boards of directors as the backbone of corporate governance and corporate social responsibility (CSR) practices in the banking industry. The underlying idea is that some characteristics of bank boards, in particular independence and gender diversity, may impact the CSR commitments of banks. By making use of a sample of 159 banks in nine countries during the period 2004–2010, our empirical evidence suggests that banks with more independent directors and more female members on their boards incline toward socially responsible behaviour. Our results also suggest that institutional factors play a significant role in these effects. They show that in greater regulatory and stronger investor protection environments, board independence and gender diversity have more influence on the social behaviour of banks.  相似文献

This paper aims to present the valuation of options using the Black-Scholes method assuming α-stable distributions as an alternative option valuation in the Mexican market. The use of α-stable distributions for modelling financial series allows to overcome the classical valuation main weakness which assumes normality, by capturing the presence of heavy tails and asymmetry in financial time series. One of the main results is the price differential between the two models and the effect of alpha and beta parameters on prices; to show the difference valuation is made of a call option and a put option for the peso-dollar exchange rate. Likewise, basic sensitivity measurements of options (delta, gamma, and rho) were made and the effect of the stability parameter (α) was made on the implied volatility of options assuming the α-stable price as the market price.  相似文献

This paper reviews and analyses the rationale for an innovation policy in services. It focuses on the relevance of the various categories of market and system failures, on the basis of economic arguments and some empirical evidence at EU level. Results show that market and system failures affect service innovation, so that there are no economic reasons supporting any discrimination of policy actions against service activities. Moreover, some of the market and system failures may be even more relevant in the field of services than of goods, although differences between categories of services should be also taken into consideration.  相似文献

ABSTRACT

Despite the increasingly favorable environment enjoyed by product placement, the question of whether this technique produces stronger behavioral effects than conventional advertising remains largely unexplored. Based on the transportation-imagery model, we hypothesized that, among users of well-established products, promotional stimuli produce stronger effects on brand choice when integrated into movies than when presented as independent ads, while among nonusers, no differences are expected. Our hypotheses were confirmed in a field experiment that compared the effects of a Coca-Cola placement within the movie Ways to Live Forever with the same Coca-Cola stimulus shown as a usual commercial.  相似文献

Since there are so few controls over detecting and preventing faculty misconduct, one of the most common ways in which it is discovered is through student reports (in other words, whistleblowing). Given the importance of student reports in bringing to light faculty’s ethical lapses, this paper seeks to understand what factors influence students’ likelihood to report faculty misconduct. We develop an empirical model that integrates the decision process of the Prosocial Organizational Behavior (POB) Model with insights from the emotional perspective on whistleblowing. Specifically, we use an experimental survey to examine how students’ perceived unfairness of the faculty misconduct, feelings of anger, and the students’ self-interest in the situation in conjunction with situational “cues for inaction” lead to the intention to blow the whistle. Overall, the results from our structural model partially support our theoretical model. Interestingly, these findings demonstrate that, in the case of faculty member misconduct, anger and perceptions of unfairness play a greater role than the more rational cost-benefit process of the POB model. These results could aid in development of ethics education for students and could also inform the development of university policies that encourage students to come forward when faced with faculty misconduct.  相似文献

The growing interest organizations have in concepts like social involvement and sustainability has helped unite programs and practices of different natures, mostly in the form of large investments in local communities. But what role can employees play in achieving this corporate aim, and how do these policies affect the way employees see their organization? Unión Fenosa has been a pioneer in the Spanish business community in maintaining corporate social responsibility and the commitment of its employees to these values. An analysis of its Solidarity Day policy shows the perspective of its employees, their motivation, and the relations between them and their company.  相似文献
