The purpose of this study is to identify generational differences and similarities among hospitality employees and managers in order to develop leadership strategies and management styles that can be utilized to increase employee morale and productivity while enhancing recruitment and retention rates of highly qualified workers. Data for this study were collected through a series of in-depth focus group discussions. Findings indicated significant generational differences in world views, attitudes toward authority and perspectives on work. Findings suggested the Baby Boomers respect authority and hierarchy, while the Generation X-ers (Gen X-ers) rebel against authority. Findings also suggested while Baby Boomers live to work, Gen X-ers work to live. The Baby Boomers are willing to wait their turn for promotions and rewards, and are very loyal. On the other hand, Gen X-ers expect immediate recognition through title, praise, promotion, and pay. They also want a life outside of work—they are not likely to sacrifice theirs for the company. The Millennial Generation believes in collective action, with optimism of the future, and trust in centralized authority. They like teamwork, showing a strong will to get things done with a great spirit.  相似文献

When agents compete for a bonus and their productivity in each of several possible occasions depends stochastically on (constant) effort, the number of times this is checked to assign the bonus affects the level of uncertainty in the selection process. Uncertainty, in turn, is expected to increase the effort made by competing agents (Cowen and Glazer, 1996; Dubey and Haimanko, 2003; Dubey and Wu, 2001). Theoretical predictions are derived and experimental evidence is collected for two competing agents, with the bonus awarded to that agent who outperforms the other. Sampling occasions (1 or 3), cost of production (high or low), cost symmetry (asymmetric or symmetric), and piece‐rate reward are manipulated factorially to test the robustness of the effects of uncertainty. For control, a single‐agent case is included. Results indicate that, for tournaments, greater uncertainty does indeed lead to greater than expected effort and lower average variable costs.  相似文献

Time series momentum   总被引:1,自引:0,他引:1  
We document significant “time series momentum” in equity index, currency, commodity, and bond futures for each of the 58 liquid instruments we consider. We find persistence in returns for one to 12 months that partially reverses over longer horizons, consistent with sentiment theories of initial under-reaction and delayed over-reaction. A diversified portfolio of time series momentum strategies across all asset classes delivers substantial abnormal returns with little exposure to standard asset pricing factors and performs best during extreme markets. Examining the trading activities of speculators and hedgers, we find that speculators profit from time series momentum at the expense of hedgers.  相似文献

Consumers are increasingly using technologies such as wearables or mobile apps to achieve their self-improvement goals. Such technologies often contain features that enable social interdependence (competition or cooperation) among users to support them in improving their engagement, performance, and well-being (life satisfaction and personal growth). However, the critical question remains: does competition or cooperation best serve users in attaining these self-improvement goals? Evidence from an online experiment and a field study reveals that competition is more effective in driving performance and personal growth, while cooperation is superior in terms of behavioral engagement and life satisfaction. Furthermore, the results indicate that the effects are mediated by strive for success and fear of failure, two counteracting psychological processes. While competition is the stronger trigger for both pathways, downstream effects vary depending on the self-improvement goal considered. This research thus provides insights into whether and how users can best realize their self-improvement goals using technologies that include social features.  相似文献

Current literature argues that firms should have strong ties to customers to benefit from increased customer retention and loyalty. Strong ties, however, have also shown to prevent innovation, suggesting that firms should also develop weak ties to other customer groups. This paper focuses on the potential for strong ties to facilitate, rather than prohibit, innovation. It is based in a 7‐year longitudinal research project with Adidas, a global sporting goods company. From the case, we find that the paradox of tie strength results from an overly simplified view of the nature of company–customer relationships. Contrary to the established literature, we find that strong ties in the Adidas case supported significant innovation. In fact, the involvement resulted in the development of a new product with a radically different product architecture and led to one of the most successful product launches in the company's history. To explain these findings, we introduce the nature of customer participation in a firm's value creation processes as a new dimension of the constitution of firm–customer ties and discuss how such a kind of relationship can develop.  相似文献

This paper is inspired by two papers of Riegel who proposed to consider the paid and incurred loss development of the individual claims and to use a filter in order to separate small and large claims and to construct loss development squares for the paid or incurred small or large claims and for the numbers of large claims. We show that such loss development squares can be constructed from collective models for the accident years. Moreover, under certain assumptions on these collective models, we show that a development pattern exists for each of these loss development squares, which implies that various methods of loss reserving can be used for prediction and that the chain ladder method is a natural method for the prediction of future numbers of large claims.  相似文献

Enforcement can affect compliance directly and indirectly, through spillovers. We study intertemporal enforcement spillovers by conducting a randomized field experiment in a university exam. The initial phase of the experiment is the exam itself. We induce variation in enforcement by randomly assigning students to rooms with different monitoring levels. The second phase is post-exam. In this phase, all students are subject to the same low level of monitoring. Our outcome variable is the probability that students steal a pen in the post-exam phase. We find that enforcement in the exam phase has a strong intertemporal spillover on compliance in the post-exam phase: students subject to a high monitoring level in the initial phase are about 33% less likely to steal the pen than students subject to low initial monitoring.  相似文献

We consider the problem of causal effect heterogeneity from a Bayesian point of view. This is accomplished by introducing a three-equation system, similar in spirit to the work of Heckman and Vytlacil (1998), describing the joint determination of a scalar outcome, an endogenous “treatment” variable, and an individual-specific causal return to that treatment. We describe a Bayesian posterior simulator for fitting this model which recovers far more than the average causal effect in the population, the object which has been the focus of most previous work. Parameter identification and generalized methods for flexibly modeling the outcome and return heterogeneity distributions are also discussed.Combining data sets from High School and Beyond (HSB) and the 1980 Census, we illustrate our methods in practice and investigate heterogeneity in returns to education. Our analysis decomposes the impact of key HSB covariates on log wages into three parts: a “direct” effect and two separate indirect effects through educational attainment and returns to education. Our results strongly suggest that the quantity of schooling attained is determined, at least in part, by the individual’s own return to education. Specifically, a one percentage point increase in the return to schooling parameter is associated with the receipt of (approximately) 0.14 more years of schooling. Furthermore, when we control for variation in returns to education across individuals, we find no difference in predicted schooling levels for men and women. However, women are predicted to attain approximately 1/4 of a year more schooling than men on average as a result of higher rates of return to investments in education.  相似文献
