Research Summary: Though research has focused on the ascent and acceptance of female CEOs, the post‐promotion circumstances female CEOs face remain unclear. In this study, we focus on a critical post‐promotion circumstance: the board chair–CEO relationship. Drawing on the gender stereotype literature, agency theory, and stewardship theory, we posit that firms appointing a female CEO are more likely to adopt a collaboration board chair orientation and less likely to adopt a control orientation. We further predict this effect is attenuated by female board representation. Using a sample of new S&P 1500 CEOs, we find support for our predictions regarding the collaboration orientation but not the control orientation. This research provides some evidence of benevolent sexism in the boardroom, with female directors acting as a countervailing influence. Managerial Summary: Whereas the notion that females encounter a glass ceiling on their path toward CEO is well documented, the conditions female CEOs encounter after promotion are less understood. The relationship between the board chair and the CEO is one important post‐promotion condition. Board chairs can focus on monitoring and/or working together with the CEO. We suggest board chairs are more likely to work in close collaboration with female CEOs than with male CEOs. We attribute this to benevolent sexism, which explains that board chairs are more likely to collaborate with female CEOs because they view females as more conducive to, and in need of, this type of relationship. We also suggest this benevolent sexism is less prevalent when there are more females on the board. 相似文献

Most studies find little to no effect of classroom computers on student achievement. We suggest that this null effect may combine positive effects of computer uses without equivalently effective alternative traditional teaching practices and negative effects of uses that substitute more effective teaching practices. Our correlated random effects models exploit within‐student between‐subject variation in different computer uses in the international TIMSS test. We find positive effects of using computers to look up information and negative effects of using computers to practice skills, resulting in overall null effects. Effects are larger for students with high socioeconomic status and mostly confined to developed countries. 相似文献

The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes. 相似文献

We examine the link between the growing emphasis on corporate social responsibility at the organizational level and beliefs about social responsibility at work (SRW) expressed by individuals. Drawing from theories of professionalism and diffusion of innovations (including practices and beliefs), we advance hypotheses about beliefs of managers and non‐managers in 11 countries at two time periods, and use a unique international data set to test our hypotheses. Our general prediction that managers would score higher than non‐managers on a measure of SRW was not supported. However, further analysis revealed a more complex relationship moderated by the contextual factors of time frame and country inequality level. We discuss implications and extensions for future research. 相似文献

In times of continuous change, companies need to adjust their business processes to gain sustainable competitive advantage.
Resulting changes in the company’s IT currently require the involvement of developers from departments that are mostly not
aligned with the business. These changes often result in high transaction and labor costs. The article presents a platform-based
method to adjust business processes with the aim of increasing both efficiency and flexibility compared to current approaches.
The core of our work is an evaluation against traditional component-based software development using a sound simulation model.
Three real-world scenarios of business process change show that – despite a slight increase in transaction costs – our suggested
method decreases labor costs while increasing operational flexibility. 相似文献

Tanzania is among the many African countries that have engaged in agricultural liberalization since the mid-1980s. in the hope that reforms that introduce price incentives and efficient marketing will encourage producers to respond. This paper assesses that claim by examining the supply response of agricultural output in Tanzania. Our estimates suggest that aggregate agricultural supply response is quite high so that the potential for agricultural sector response to liberalization of agricultural prices and marketing may be quite significant. The long-run elasticity of aggregate food crop output to relative prices was almost unity. Short-run supply responses were estimated at about 0.35 for aggregate food crops and for all (food and export) crops. Liberalization of agricultural markets, where it increases the effective prices paid to farmers, can be effective in promoting production, although complementary interventions, to improve infrastructure, marketing, access to inputs and credit, improved production technology etc, are probably necessary. 相似文献

Die Eurozone ist vor allem durch die gef?hrdete Kreditwürdigkeit Griechenlands in eine schwere Krise geraten. Jetzt zeigt
sich, dass jede W?hrungsunion ein Konstruktionsproblem hat. Die Mitgliedstaaten müssen auf die Autonomie in der Geldpolitik
verzichten und ohne die Instrumente der Geld- und Wechselkurspolitik ihre internationale Wettbewerbsf?higkeit bewahren. 相似文献

As far as we are aware, this study presents the first comparative analysis of the stock picking and market timing abilities of managers of conventional and socially responsible (SR) pension funds, and of their use of superior information. For the United Kingdom, the results obtained show a slight stock picking ability on the part of SR pension fund managers (although it disappears if multifactorial models are considered), and a negative market timing ability on the part of both SR and conventional pension fund managers (these results hold for multifactorial models controlled by home bias). In relation to the management styles, both conventional and SR pension funds usually invest in small cap and growth values, although it is the SR pension funds that are the most exposed to these styles. We also observed that, while conventional pension fund managers make certain use of superior information to follow stock picking strategies, managers of SR pension funds use superior information to follow market timing strategies. 相似文献
