Según un modelo de equilibrio generalde dos esferas (hogary mercado), la productividad de la mujer en el trabajo remunerado disminuye cuantas más tareas desempeña en el hogar. Partiendo del supuesto de que las aportaciones de hombres y mujeres a las labores domésticas son complementarias, las autoras comprueban que hay múltiples equilibrios posibles. En algunos, ellosy ellas asumen estas tareas por igualy ganan salarios iguales; en otros, se las reparten de manera dispar y ganan salarios diferentes. Por otraparte, los estereotipos acerca de la productividad de las mujeres perpetúan la desigualdad. Las autoras, valiéndose de ejemplos numéricos, demuestran que hay mayor bienestar cuando los cónyuges se reparten el trabajo a partes iguales. Para terminar, exponen algunas conclusiones. 相似文献

Diversity perspectives are philosophies of or approaches to diversity held by organizations, groups, or executives. They are important for organizations because they can determine the success or failure of diversity in the workforce. However, little is known about the predictors of diversity perspectives among executives. Using fuzzy set qualitative comparative analysis, we analyzed 50 interviews with top executives in Germany to identify individual and organizational characteristics that predict executives' adoption of a diversity perspective, in particular of a value‐in‐diversity perspective. Specifically, we analyzed gender, age, education level, vocational background, and tenure (individual characteristics), as well as size, sector of organization, and competitive environment (organizational characteristics), as potential predictors. We found single characteristics did not predict adoption, but configurations of characteristics did. Drawing on the person‐situation‐interactionist perspective, we developed specific profiles of executives likely to foster a value‐in‐diversity perspective and identified characteristics of their work environments that support such an approach. Theoretical and practical implications are discussed. 相似文献

We consider (two-person) bargaining games and we assume that the agents want to apply two possibly different bargaining solutions.
A mechanism is a function which assigns an allocation to every bargaining game and every pair of bargaining solutions. Examining
van Damme's mechanism (1986) from a cooperative point of view we see that it fails to satisfy Pareto-optimality. By modifying
it we propose a new mechanism yielding the same conclusions as the original while enjoying some additional desirable properties.

Abstract We consider the issue of modeling the latent or hidden exposure occurring through either incomplete data or an unobserved underlying risk factor. We use the celebrated expectationmaximization (EM) algorithm as a convenient tool in detecting latent (unobserved) risks in finite mixture models of claim severity and in problems where data imputation is needed. We provide examples of applicability of the methodology based on real-life auto injury claim data and compare, when possible, the accuracy of our methods with that of standard techniques. Sample data and an EM algorithm program are included to allow readers to experiment with the EM methodology themselves. 相似文献

This study examines the effect of the timing of follow-ups, different incentives, length, and presentation of the questionnaire on the response rate and response quality in an online experimental setting. The results show that short questionnaires have a higher response rate, although long questionnaires still generate a surprisingly high response. Furthermore, vouchers seem to be the most effective incentive in long questionnaires, while lotteries are more efficient in short surveys. A follow-up study revealed that lotteries with small prizes, but a higher chance of winning are most effective in increasing the response rate. Enhancing questionnaires with visual elements, such as product images, lead to a higher response quality and generate interesting interaction effects with the length of the questionnaire and the incentives used. Finally, the timing of the follow-up has no significant influence on the response rate. 相似文献

This paper examines changes in local working conditions instigated by the development of contract research organisations in pharmaceutical development. These developments are seen as occurring in the context of Sweden's ‘circumscribed neoliberalization’. It is shown how staff remain ambivalent about the shifts of location and identity that these developments imply. 相似文献

This paper explores to what extent large French firms in the hands of wealthy families have performed in a significantly different manner from non-familial firms. The results of the econometric analysis confirms the Monsen Downs Williamson theory according to which only a combination of size and divergent goals could cause deviations from profit-maximization. Indeed, it is established that when ownership and management are not essentially separate, large size has a systematically better impact upon profitability than when such a divorce exists. Differences in financial structure viz leverage do not affect the result. 相似文献

Sport sponsorship is an important marketing communication tool, and stakes in sponsorship deals are high. Therefore, sponsors strive to ensure that their investments are effective and protected from competitors—that is, ambusher marketers’ attacks. Still, little is known about how ambush marketing affects sponsor identification and misidentification of ambushers as sponsors. This study investigates levels of sponsor and ambusher identification in three experimental settings, controlling for the presence/absence of an ambusher, communication modality, and response formats. A field study in the context of a large sports event demonstrates the external validity of the findings. The results provide evidence of a nondestructive interference of ambush marketing, indicating that ambush marketing does not necessarily harm sponsor identification. Misidentification of nonsponsors as sponsors occurs because of the indirect link established between the event and the company through ambush marketing, but not as a consequence of other communication activities by a competitor with no link to the event. Finally, a combined sponsor–ambusher perspective indicates that sponsors do not necessarily have a consistent “official sponsor” advantage over ambushers. Findings are discussed with emphasis on implications for sponsors, ambushers, and marketing researchers. 相似文献
