The fragility of the CAPM has led to a resurgence of research that frequently uses trading strategies based on sorting procedures to uncover relations between firm characteristics (such as “value” or “glamour”) and equity returns. We examine the propensity of these strategies to generate statistically and economically significant profits due to our familiarity with the data. Under plausible assumptions, data snooping can account for up to 50 percent of the in‐sample relations between firm characteristics and returns uncovered using single (one‐way) sorts. The biases can be much larger if we simultaneously condition returns on two (or more) characteristics.  相似文献

This paper analyses investors’ ability to identify if managers use corporate social responsibility as an entrenchment practice to conceal the risk of dismissal associated with managerial discretion and if this detection is determined by the level of investor protection orientation. Results based on an international database of 1949 companies show that investors and markets do not identify managerial entrenchment based on the promotion of sustainable practices, except when such entrenchment is developed by companies located in countries with strong investor protection. In these countries, investors identify and penalise such companies with lower financial performance.  相似文献

Increasingly, national brands have cast people from marginalized groups in advertising. It is important to understand the elements that influence consumers’ responses to advertisements featuring groups who have been traditionally excluded from advertising campaigns. Although consumers may wish to buy brands that support their own views on human rights and equality, we propose that consumers in the target market may be uncomfortable if the group portrayal contradicts their beliefs about the topic, concept, or social groups in the ad. Across two studies, we show that when an ad creates this type of internal contradiction within consumers, it may elicit a more negative response than an ad portraying a more traditional model. However, we also find preliminary evidence that using models from marginalized groups can be more effective than using more traditional models—as long as such portrayals do not violate certain target consumers’ schemas. The implications of these results will be discussed.  相似文献

This study examined college students' drinking behaviors from a consumer behavioral perspective. A consumer‐oriented, cognitive, and behavioral‐hierarchical decision‐making model was developed and tested with the use of structural equation modeling. Questionnaires were collected from undergraduate students ( n = 269) attending a large state university in the southwestern United States. Results indicated that personal values can serve as significant predictors of the attitudes college students have toward alcohol use, which in turn can predict intentions to drink. Results also indicated that intentions to drink are strongly related to actual alcohol consumption, and that gender‐predicted attitudes and alcohol use during the past month influences intentions to drink. However, the structure of the model was similar after controlling for gender differences in alcohol use and for the stability of past behavior. The model delineated the specific roles played by personal values (self‐actualizing values vs. social–hedonic values) and attitudes toward the physical and psychological consequences of drinking. Overall, social–hedonic values and psychological consequences predicted actual alcohol consumption far better than did self‐actualizing values and physical consequences, respectively. Theoretical and practical implications are discussed, and directions for future research are suggested. © 2005 Wiley Periodicals, Inc.  相似文献

We present details of the design and implementation of the 2020–2021 JobKeeper program and review the literature on its impacts. JobKeeper stimulated the macroeconomy and restrained job loss in the downturn. But because the program was not narrowly targeted, the cost per job saved was high and the impact most likely regressive. However, it would not have been possible to devise and implement a more targeted program in the available time, and as it was, JobKeeper was arguably implemented later than needed for maximum effectiveness. We therefore recommend that Australia consider establishing a short-time work program for use in future recessions.  相似文献

“Business climate indexes” characterize state economic policies, and are often used to try to influence economic policy debate. However, they are also useful in research as summaries of a large number of state policies that cannot be studied simultaneously. Prior research found that business climate indexes focused on productivity and quality of life do not predict economic growth, while indexes emphasizing taxes and costs of doing business indicate that low‐tax, low‐cost states have faster growth of employment, wages, and output. In this paper, we study the relationship between these two categories of business climate indexes and the promotion of equality or inequality. We do not find that the productivity/quality‐of‐life indexes predict more equitable outcomes, although some of the policies underlying them suggest they might. We do find, however, that the same tax‐and‐cost‐related indexes that are associated with higher economic growth are also associated with increases in inequality.  相似文献

We perform peridogram based cycle analysis of firm capital structure and find evidence that firms’ leverage is both persistent and cyclical. The cyclicality of leverage is supported by the trade-off, pecking order and market timing capital structure theories (Korajczyk and Levy in J Financ Econ 68:75–109, 2003; Bhamra et al. in Rev Financ Stud 23:645–703, 2010). Although market timing theory research supports persistence, previous literature dictates that the trade-off and pecking order theories may predict either persistent or mean reverting leverage. Our tests reject mean reversion in favor of persistent and cyclical leverage. We corroborate pecking order theory literature that predicts leverage is persistent. In these models, when firms’ investment spending is below earnings, leverage decreases. In addition, we examine whether firms change their capital structure as a result of business and financial cycles. Since financial cycles last longer than business cycles, financial cycles should have a long term effect on leverage. Our findings confirm the persistent leverage business cycle models that suggest firms change their capital structure due to financial and credit cycles (Jermann and Quadrini in Am Econ Rev 102:238–271, 2012; Azariadis et al. in Rev Econ Stud 83:1364–1405, 2016). We conclude that leverage is persistent due to the cyclicality of the financing decision.  相似文献

Research on how cross-sector partnerships (CSPs) contribute toward addressing societal grand challenges (SGCs) has burgeoned, yet studies differ significantly in what scholars analyze and how. These differences matter as they influence the reported results. In the absence of a comprehensive framework to expose the analytical choices behind each study and their implications, this diversity challenges interpretation and consolidation of evidence upon which novel theory and practical interventions can be developed. In this study, we conduct a systematic review of scholarly analysis in CSP management studies to develop a framework that contextualizes the SGC-related evidence and reveals scholars’ analytical choices and their implications. Conceptually, we advance the term ‘SGC interventions’ to illuminate the black box leading to SGC-related effects, thus helping to differentiate between transformative versus mitigative interventions in scholars’ analytical focus. Moreover, the framework stresses the logical interplay between the framing of the SGC-related problem and the reporting of the intervention's effects. Through this, we juxtapose what we call problem-centric versus solution-centric SGC analysis and so differentiate between their analytical purpose. We discuss the framework's implications for advancing an SGC perspective in scholarly analysis of CSPs and outline avenues for future research.  相似文献

From a simple dynamic model of competition between product lines it is shown that the shape of learning curves has a powerful influence on the dynamics of technological substitution. Learning of both production efficiency and marketing efficiency is considered. It is asserted that both types of learning are important and that the two are complementary. It is further speculated that production learning is probably more important for commodities and in situations of low per capita income, whereas market learning gains ascendancy in cases of high income and specialized and diversified product lines. In closing, it is noted that simple competitive models are misleading, first because complementarities and coevolutionary processes are probably as important in the overall development of technology as are competitive processes, and second because optimization of the technological system's parts does not guarantee improvement of the performance of the system as a whole.  相似文献
