This study investigates the usage of tobacco, alcohol, and cannabis among hotel employees in the resort city of Eilat. Data obtained from a sample of 458 respondents, drawn from three hotel chains, provides evidence of workers’ substance consumption in light of their socio-demographic backgrounds and specific job characteristics. The results indicate a higher rate of substance use among study participants in comparison to the average in Israeli society. Substance use was found to be the most prevalent among young, single male employees with relatively low levels of education. In terms of job characteristics, front-of-the-house employees were more prone to binge drinking than back-of-the house employees. It is suggested that work-related programs and policies, such as sensible drinking workshops and smoking cessation programs, may help prevent alcohol misuse and reduce extensive substance use among hotel staff. 相似文献

Dividend Changes and Future Profitability 总被引:9,自引:0,他引:9
We investigate the relation between dividend changes and future profitability, measured in terms of either future earnings or future abnormal earnings. Supporting "the information content of dividends hypothesis," we find that dividend changes provide information about the level of profitability in subsequent years, incremental to market and accounting data. We also document that dividend changes are positively related to earnings changes in each of the two years after the dividend change. 相似文献

We analyze the puzzling behavior of the volatility of individual stock returns over the past few decades. The literature has provided many different explanations to the trend in volatility and this paper tests the viability of the different explanations. Virtually all current theoretical arguments that are provided for the trend in the average level of volatility over time lend themselves to explanations about the difference in volatility levels between firms in the cross-section. We therefore focus separately on the cross-sectional and time-series explanatory power of the different proxies. We fail to find a proxy that is able to explain both dimensions well. In particular, we find that Cao et al. [Cao, C., Simin, T.T., Zhao, J., 2008. Can growth options explain the trend in idiosyncratic risk? Review of Financial Studies 21, 2599-2633] market-to-book ratio tracks average volatility levels well, but has no cross-sectional explanatory power. On the other hand, the low-price proxy suggested by Brandt et al. [Brandt, M.W., Brav, A., Graham, J.R., Kumar, A., 2010. The idiosyncratic volatility puzzle: time trend or speculative episodes. Review of Financial Studies 23, 863-899] has much cross-sectional explanatory power, but has virtually no time-series explanatory power. We also find that the different proxies do not explain the trend in volatility in the period prior to 1995 (R-squared of virtually zero), but explain rather well the trend in volatility at the turn of the Millennium (1995-2005). 相似文献

This paper studies how to assign “monitors” to productive agents in order to generate signals about the agents' performance that are most useful from a contracting perspective. We show that if signals generated by the same monitor are negatively (positively) correlated, then the optimal monitoring assignment will be “focused” (“dispersed”). This holds because dispersed monitoring allows the firm to better utilize relative performance evaluation. On the other hand, if each monitor communicates only an aggregated signal to the principal, then focused monitoring is always optimal since aggregation undermines relative performance evaluation. We also study team‐based compensation and randomized monitoring assignments. In particular, we show that the firm can gain from randomizing the monitoring assignment, compared with the optimal linear deterministic contract. Furthermore, under randomization, the conditional expected utility for the agent is higher when the agent is not monitored compared with the case where the agent is monitored. That is, the chance of being monitored serves as a “stick” rather than a “carrot”. 相似文献

The aim of this paper is to investigate the existence and nature of seasonality (deterministic or stochastic) in tanker freight markets and measure and compare it across sub-sectors and under different market conditions (expansionary and contractionary) for the period January 1978 to December 1996. The existence of stochastic seasonality is rejected for all freight series while results on deterministic seasonality indicate increases in rates in November and December and decreases in rates from January to April. Seasonality is found to be varying across markets depending on vessel size and market condition. Seasonality comparisons under different market conditions, an issue investigated for the first time in the econometrics literature using Markov Switching models, reveal that seasonal rate movements are more pronounced when the market is recovering compared to smaller changes when the market is falling. This is well in line with the low and high elasticity of supply expected in expansionary and contractionary periods of shipping markets. The results have implications for tactical shipping operations such as budget planning, timing of dry-docking, vessel speed adjustments and repositioning. As expected, the out-of-sample forecasting performance of these Markov Regime Switching models is lacking somewhat, a result which is thought to be a consequence of having to predict ‘states’ simultaneously with mean values. 相似文献

Consumers in today's world are confronted with the alarming consequences of unsustainable behavior such as pollution and resource degradation. In addition, they are facing increases in uncertainty due to external events such as economic crises and terror attacks. These two problems are central to consumers' lives, occur on a global scale, and have significant impact on the world's political, economic, environmental, and social landscapes. Contributing to research on persuasion and pro-social behavior, we show in four studies, conducted online, in the lab, and in the field, that these two problems are interconnected. Studies 1 and 2 demonstrate that uncertainty leads to lower levels of sustainable behavior in comparison to certainty. Study 2 reveals in addition that this is due to the display of higher levels of temporal discounting under uncertainty (i.e., adopting a more immediate orientation). Finally, Studies 3 and 4 show that emphasizing the immediate benefits of sustainability during uncertainty reverses the negative effect and leads consumers to act more sustainably. Overall, these findings provide valuable implications for policy makers and responsible marketers. 相似文献

This research investigates how the combination of aesthetically appealing and unappealing visual elements in marketing communications can motivate prosocial behavior. Prior literature has investigated the effectiveness of aesthetically pleasing or displeasing visuals separately and has reported mixed results. Based on the notion that empathy is a key driver of prosocial behavior, the current work first makes a theoretical distinction between two antecedents of empathy—identification and perceived need—and then illustrates how these antecedents are evoked by pleasing and displeasing visual elements, respectively. The authors show that the combination of a pleasing individual (human or object) and a displeasing group is particularly effective in evoking identification and perceived need, and therefore empathy. The elevated empathy, in turn, motivates prosocial behavior. Five main experiments in the field, lab, and online, as well as a pre-study and two post-studies, provide supportive empirical evidence. Implications for theory and practice are discussed. 相似文献

Drawing on a perspective which takes into account the convergences of sovereign and biopolitical ruling apparatuses, the aim of this article is to provide a comprehensive view of the Separation Wall constructed by Israel in East Jerusalem, and, through it, of Israeli control of Palestinian East Jerusalem. Neither a comprehensive border, nor a mere barrier, the Separation Wall which is being constructed in Jerusalem operates to reinstates sovereign power in arrays of governmentality for the purpose of drawing on the ability of sovereignty to appropriate legitimacy for the territorialisation of governmentality. This article claims that these territorialised arrays of governmentality give rise to processes of racialisation, by maintaining a grip on the communities of Palestinians in East Jerusalem and sustaining them in an intermediate position, standing in the way of their full integration into the Israeli population while severing their existing connections with the Palestinians in the West Bank. 相似文献
