Using an international sample of environmental and social firm-level ratings between 2007 and 2019, we form synthetic overlapping region-based equity portfolios to examine the impact of screening stringency on abnormal returns and specific risk. While previous literature analyzes this relationship in a bidimensional setting, inferences made in this study are additionally robust to regional levels of market efficiency. Our results suggest that (1) screening stringency displays an inverted curvilinear relationship with risk-adjusted returns and (2) the impact on specific risk is strictly increasing. Thus, portfolios that employ marginal and substantial screening incur the cost of responsible investing. However, moderate screening has the benefit of increasing performance without the burden of financing the least responsible corporations.  相似文献

Despite the extensive research in both the determinants and the results of corporate social responsibility (CSR), relatively few studies have considered extra-legal institutions as potential determinants of CSR. Our work fills this gap by looking at how media attention affects CSR over a long-term period in a continental European setting. Our results show that media coverage positively affects CSR. Additional scrutiny triggered by media coverage encourages dominant owners to signal their commitment to limiting self-dealing transactions and their orientation toward stakeholders' needs through CSR investments. Additionally, our results reveal that this signaling device offers greater benefits and lower costs in firms where controlling owners show a voting-cash flow wedge. Our results are relevant to different actors such as investors, auditors, and policy makers as they provide solid evidence that media coverage is an important driver of CSR orientation in a continental European setting.  相似文献

Virtual music festivals (VMFs) are a great opportunity for the music industry to improve high quality digital events; as an alternative consumption phenomenon, VMFs can reach hybrid audiences and help in the challenge of digitalization. This study aims to investigate the multidimensional structure of consumer value in VMFs (intra-variable perspective), as well as the effects of value on cognitive versus affective satisfaction and loyalty (inter-variable perspective). Using a qualitative–quantitative approach—focus group and survey with festival attendees (n = 246)—, a value structure of VMF is tested with partial least square–SEM as a reflective-formative-formative third-order model. Benefits and sacrifices are second-order constructs, while five positives (escape, novelty, enjoyment, musical content, and socialization) and two negatives (monetary and nonmonetary costs) are first-order ones. Results show VMFs value as a multidimensional trade-off, where socialization is not contributing to value, but a balance between cognitive (musical content) and affective (enjoyment, and less escape and novelty) exists. Furthermore, consumer value intensifies both cognitive and affective satisfaction, but just the former affects loyalty. These findings provide new insights to better understand the decision-making processes of virtual festival attendees.  相似文献

While prior consumer studies have adopted various theoretical perspectives to explain individuals' reactions to disasters, scant attention has been paid to the role of ontological security in shaping those responses. This study attempts to fill this knowledge gap by qualitatively exploring ontological security in two contexts: man-made and natural disasters. To this end, we conducted 35 focus groups in the UK, Germany, and France to address how people reacted to terrorist attacks and the COVID-19 pandemic respectively. Through thematic analysis, three themes emerged: fear versus anxiety, oneself versus others, and materialistic versus experiential purchases. Man-made disasters appear to elicit fear, concern for self, and a preference for materialistic purchases, whereas natural disasters seem to trigger anxiety, concern for others, and a preference for experiential purchases. Both types of disasters seem to evoke a desire to escape from reality. In closing, we discuss both transitory and prolonged threats to ontological security and how they shape individuals' behaviours while restoring their security.  相似文献

When developing products and services for base of the economic pyramid (BoP) consumers, it has been widely assumed that organizations must set extremely low prices that are dependent on substantial product acceptance and economies of scale. However, such pricing is often not feasible. Growing evidence suggests that more moderate price levels are needed for organizations to viably serve the needs of low-income consumers. However, price sensitivity is less understood in low-income contexts. To promote the success of social enterprises through fresh insight, we reexamine the extremely low-price BoP assumption by investigating product acceptance among low-income consumers using two experiments in Latin America. Results reveal that a belief in one's capabilities to make effective consumption decisions, consumer self-confidence, helps explain the acceptance of moderately-priced products. Discussion highlights directions for stimulating acceptance of socially beneficial products in low-income contexts.  相似文献

Benefits and costs associated to hubbing practices of airlines are still subject to much debate. In the previous literature, some standard spatial concentration indices have been proposed to measure it. However, we show that these indices are “ill-defined” because they do not take into account the salient characteristic of hubbing: connecting passengers. The purpose of this research is to present a new methodology which avoids the pitfalls of other methods. Our new methodology also analyzes the level of concentration of the connecting passengers studying two different dimensions: hub airports and routes. Finally, we apply our methodology to some US carriers.  相似文献

The magnitude 7.0 earthquake that struck Haiti in January 2010 led to an unprecedented effort in collecting and providing geographical information in support of humanitarian aid. Although most of the compiled datasets and generated maps were able to provide specific and detailed information regarding the location of damaged buildings and road interruptions, none or little information was available to describe the accessibility—or otherwise—of the urban space. Here we try to offer an alternative method to define the urban accessibility landscape in the aftermath of earthquake damage, by combining simple graph theory concepts and GIS-based spatial analysis to assess how the urban space accessibility decreases when the road network is damaged.  相似文献
