A bstract .   Antidiscrimination laws are designed to prompt employers to stop excluding black workers from jobs they offer and from treating them unequally with respect to promotion and salaries once on the job. However, a moral hazard effect can arise if the existence of the laws leads black employees to bring unjustified claims of discrimination against employers. It has been argued that employers may become more reluctant to hire black workers for fear of being subjected to frivolous lawsuits.
Using the Multi-City Study of Urban Inequality (MCSUI), we find that male and female black workers are far more likely than whites to report racial discrimination at work. This is the case even when a host of human capital and labor market factors are controlled for. Further, nearly all black workers who report they have been discriminated against on the job in the MCSUI Surveys also show statistical evidence of wage discrimination. This is not the case for white males or females. We find little evidence to support a moral hazard effect.  相似文献

Return enhancement trading strategies for size based portfolios   总被引:1,自引:1,他引:0  
Recent theoretical work suggests that definitions of market efficiency that allow for the possibility of time-varying risk-premia will generally lead to return sign predictability. Consistent with this theory, we show that a logit model based on the lagged value of the market risk premium is useful for successfully predicting the return sign for CRSP small decile portfolio returns, but not large ones. We additionally employ this model in market timing simulations of micro-cap mutual funds in which investment can actually be made. The results indicate that a market-timing strategy based on our return-sign forecasting model outperforms a buy-and-hold strategy for 13 of 14 micro-cap funds studied. On average, the buy-and-hold strategy produces an average compound return of 11.98% per annum versus an average of 16.60% for the market-timing strategy. Nevertheless, trading restrictions make the return-sign forecasting model more practical to employ by the micro-cap fund portfolio manager rather than the individual fund investor.

Interest in the employee engagement construct has gained increasing attention in recent years. Measurement tools focused on nuanced areas of engagement (i.e., job engagement and organizational engagement) have been offered; however, no measure of employee engagement has been advanced despite persistent calls in the research. We present the development, method, and results of a three‐dimensional employee engagement measurement tool developed for use in the human resource and management fields of study. Across four independent studies, the employee engagement scale (EES) was found to consist of three subfactors (cognitive, emotional, and behavioral) and a higher‐order factor (employee engagement). Across a series of four studies, we explored the factor structure and reliability of the EES (Study 1), then refined the scale, confirmed the factor structure, and examined reliability and both convergent and nomological validity evidence (Study 2). Next (Study 3), we completed a final reduction in scale items and examined additional evidence of reliability and nomological validity as well as evidence of discriminant validity. Finally (Study 4), we tested for evidence of incremental validity. In the implications for theory and practice section, we discuss the importance of an employee engagement measure aligned alongside an agreed‐upon definition and framework. Limitations and future directions for research—such as the need for further psychometric testing and exploring issues of measurement invariance—are discussed. © 2016 Wiley Periodicals, Inc.  相似文献

This study provides an update to Mixon and Upadhyaya’s (2001) ranking of Southern economics departments using research output indexed in EconLit. Ranking results from a ‘core’ (i.e. the top five faculty researchers) of each institution’s economics department reveal that Vanderbilt University, George Mason University, Johns Hopkins University, the University of Maryland and Georgia State University currently maintain the top five economics departments, respectively, in the US South. Relatedly, the five institutions rising the most from Mixon and Upadhyaya (2001) are Tulane University, Georgia State University, University of Texas–Dallas, Rice University and Florida International University, respectively.  相似文献

Food security concern in China is also the world’s concern. Studies on food consumption in the past, however, often neglected the increasing food consumed away from home (FAFH). Drawn on a survey data recently conducted in nine cities by a week-long diary method, we found that FAFH in urban China accounts for a significant proportion of total food consumption, although its share varies by food category. With substantial expected income growth, overall FAFH consumption will likely continue to rise, but would be negatively affected by the rapid societal aging process, both in dining out probability and per capita consumption level. The main findings of this study have implications for food processing and service industries as well as for studies in food-related environmental issues.  相似文献

Objective: The recent development of the EDWARDS INTUITY Elite? (EIE) valve system enables the rapid deployment of a prosthetic surgical heart valve in an aortic valve replacement (AVR) procedure via both the minimally invasive (MISAVR) and conventional (CAVR) approaches. In order to understand its economic value, this study performed a cost evaluation of the EIE valve system used in a MIS rapid-deployment approach (MIS-RDAVR) vs MISAVR and CAVR, respectively, compared to standard prosthetic aortic valves.

Methods: A simulation model was developed using TreeAge (and validated with MS Excel) to compare the inpatient utilization and complication costs for each treatment arm. Thirty-day clinical end-points for the MIS-RDAVR (mortality and complications) were taken from the TRANSFORM trial; and a best evidence review of the published literature was used for the MISAVR and CAVR approaches. Studies were pooled and parameter estimates were weighted by sample size in order to compare the TRANSFORM patients. Cost data (2016 USD) were taken from the Premier database. Incremental cost and cost-effectiveness was assessed and one-way/probabilistic sensitivity analyses performed to gauge the robustness of the results.

Results: MIS-RDAVR costs $2,621 less than CAVR and had lower mortality rates, making it a superior (dominant) technology relative to CAVR. MIS-RDAVR costs $4,560 more than MISAVR, but was associated with an additional 0.20 life years-per-patient. This implies a cost-effectiveness ratio of $22,903 per-life-year-gained. Thus, MIS-RDAVR is cost-effective compared to MISAVR.

Conclusions: The EIE valve system deployed in a MIS approach appears to be a cost-effective technology compared to MISAVR and CAVR. When compared to CAVR it may achieve cost savings as well. These results suggest that MIS-RDAVR confers superior economic value compared to both standard MISAVR and CAVR via lowered key complication rates (re-operation, renal complications, wound infection, TIA, endocarditis) and utilization (cross-clamp time, hospital ward days).  相似文献

Research summary : Drawing on theory about signaling, sensemaking, and the romance of leadership, we extend inquiry on investors' perceptions of CEO succession following misconduct. Whereas past studies have treated misconduct monolithically, we examine failures of integrity and competence separately. Using a policy capturing methodology that isolates investors' decision making from potential confounds, we find that, following an integrity failure, investors perceive outside and interim successors positively but inside successors negatively. Following a competence failure, investors perceive outside successors positively but are ambivalent toward inside and interim successors. Our findings indicate that whether an act of misconduct was an integrity failure or a competence failure, and what type of successor the firm chooses, are important considerations when using CEO succession as a means to restore investor confidence. Managerial summary: Business headlines regularly feature episodes of organizational misconduct, such as product safety problems, environmental violations, employee mistreatment, and securities lawsuits, and their aftermath. In such scenarios, shareholders demand answers from the people at the top, even if those people were not directly responsible for the problem. As a result, companies often fire the CEO as a means to restore investor confidence. Does this work? It depends on the type of misconduct and who is the CEO's successor. Following a competence failure, investors welcome the appointment of an outsider, but they are indifferent to inside and interim successors. Following an integrity failure, shareholders greet outside and interim CEO successors favorably while frowning on the promotion of insiders. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

We analyze the nonlinear pricing problem faced by an incomplete information monopolist operating in a market populated by agents with budget constraints. We show that if other goods are available and if the monopolist's goods are nonessential relative to other goods, then there exists an optimal, individually rational, and incentive compatible selling mechanism for the monopolist (Theorem 1). Moreover, we show that a solution to all such nonlinear pricing problems exists if and only if the monopolist's goods are nonessential (Theorem 2). In the absence of nonessentiality, we show that if the monopolist's profit function is independent of quantity (e.g., if all costs are fixed), then an optimal selling mechanism exists (Theorem 3). Finally, we show that if there is reporting (of types by agents) and partial recognition of types (by the monopolist), then an optimal selling mechanism exists, even in the absence of nonessentiality, provided agents' utility functions are affine and continuous in goods (Theorem 4).  相似文献

Three factors considered to potentially influence salespeople's intentions to behave unethically are empirically examined. Although moral judgment is commonly considered a precursor to moral intentions, the effects of cognitive moral development and perceived competitive intensity on moral intentions are not well understood. Results suggest that all three factors influence salespeople's intention to behave unethically. Implications and directions for future research are provided.  相似文献
