We examine individual‐ and country‐level determinants of managerial employment, using data from the 1989 to 2009 waves of the World Values and European Values Surveys (n = 89,336 employed adults in 59 countries). Reflecting the rise of the transnational capitalist class, we find that factors related to globalization and international political institutions are most strongly associated with opportunities to join the managerial class relative to factors related to the business‐cycle or development. Additionally, in a subset of countries with detailed occupational information, we find that global trade has a particularly strong, positive association with the odds of being a corporate manager in a large firm.  相似文献

Estimated demographic effects in proportional hazard models of first birth intervals could reflect time-invariant differences in the risk of a birth, or differences in the timing of a shift in the risk, or both. This paper attempts to distinguish between these possibilities. The procedure is to estimate a more general model than the proportional hazard specification, in which the evolution of the risk of a birth can differ with demographic characteristics. The proportional hazard specification is nested within this more general model. Consequently, the consistency of the data with the risk or the timing interpretation of demographic effects can be tested. The data studied do not lead to a rejection of the proportional hazard specification.Department of Economics, University of Pennsylvania. The initial stage of this research was supported by a National Science Foundation Graduate Fellowship. I have benefited from insightful comments from David Bloom, Andrew Foster, Zvi Griliches, V. Joseph Hotz, Duncan Thomas, anonymous referees, and participants in seminars at Harvard University and the University of Pennsylvania, and in the Economic Demography sessions of the 1988 Population Association of America annual meetings. Any remaining errors are my own.  相似文献

The authors describe the socioeconomic characteristics and fertility patterns of female immigrants from Latin America to the United States, with a focus on reasons for fertility differentials. "Using the one per cent public use sample from the 1970 and 1980 United States census, we first compare changes in socio economic characteristics from 1970 to 1980, and then examine the determinants of fertility of female immigrants to the United States, aged 16-49, from four Latin American areas or countries of birth.... The findings...suggest that there are direct effects of demographic, assimilation, and socioeconomic variables beyond those mediated by the variables in each of these sets. Further, regardless of the model, the effect of the clusters of demographic characteristics is most apparent. Age categories and marital status are the strongest indexed determinants of immigrant fertility.... The effect of education and employment is strong. Among assimilation variables, duration of residence and language ability are significant determinants of Hispanic immigrant fertility." (SUMMARY IN FRE AND SPA)  相似文献

Leadership efficacy: Review and future directions   总被引:1,自引:0,他引:1  
The concept of leader efficacy has received relatively little attention in the leadership literature. This is somewhat surprising given that effective leadership requires high levels of agency (i.e., deliberately or intentionally exerting positive influence) and confidence. This review uses existing theory and research on leader efficacy as a point of departure for proposing an expanded and multi-level framework for understanding the domain of leadership efficacy that includes leader, follower, and collective efficacies. The primary goals are to provide a conceptual framework to stimulate future theory and research on building efficacious leadership and to understand how such leadership develops and has implications for effective performance.  相似文献

In this article, we develop an interorganizational justice model to explain cross‐border interorganizational relationships. The model contends that cultural distance (construed as the cultural differences between offshoring partners) would influence behavioral uncertainty and the boundary spanners' perceptions of justice. Specifically, the model predicts that high levels of behavioral uncertainty are likely to reduce relational commitment, whereas low levels of behavioral uncertainty are likely to enhance relational commitment. However, boundary spanners' perceptions of distributive, procedural, and interactional justice would mitigate the negative impact of behavioral uncertainty on relational commitment. The model also predicts that culturally similar boundary spanners would be more likely to share similar perceptions of distributive, procedural, and interactional justice than culturally dissimilar boundary spanners. This model has implications for further theoretical discussion and empirical research as well as management practice. Managers could use the interorganizational justice model to assess shared perceptions of justice among boundary spanners and develop transcultural justice competencies.  相似文献

The limited capabilities and resources available within many small‐ and medium‐sized enterprises frequently hamper an effective response to environmental pressures, which in turn hurts large buying firms (i.e., customers). Using a case study method with multiple suppliers of two large buying firms, we mapped factors that initiated and improved environmental capabilities in small‐ and medium‐sized enterprises over time. Through several specific mechanisms, buyers' green supply chain management initiated and then enabled the improvement of suppliers' environmental capabilities. Independent of buyers, internal championing of environmental concerns also provided an impetus for small‐ and medium‐sized enterprise suppliers to acquire resources outside the supply chain. Thus, synergistic linkages emerged in supportive buyer‐supplier relationships, resource acquisition, and capability development. When these findings are combined with earlier research on larger suppliers, an integrative framework emerges that provides direction for suppliers, buyers, and public agencies seeking to improve environmental performance.  相似文献

Luxury, historically an exclusive, rare and elitist phenomenon, is changing. This is predominantly driven by technological developments, particularly social media, and the rising level of consumer empowerment in the marketplace. A maturing stream of research has emerged assessing the effects of social media platforms on luxury brands, offerings and consumers. However, there has been no comprehensive analysis of this extant literature synthesizing the current state of knowledge and postulating future research directions. This paper addresses this gap by utilizing a systematic literature review approach. A total of 115 articles were collected and analysed and five core themes were identified, examining (1) luxury brand strategy, (2) luxury brand social media communications, (3) luxury consumer attitudes and perceptions, (4) engagement and (5) social media's influence on brand performance-related outcomes. These themes are comprehensively explored to understand the myriad impacts of social media on luxury businesses before conceptualizing the themes as a holistic framework explaining social media's role within luxury. The framework developed highlights the fragmented yet progressive nature of research on the confluence of social media and luxury, and signals fruitful avenues for further inquiry. It is proposed that scholarly attention is directed towards multiple lines of inquiry, including social media's role in luxury brand construction online, social media's role in facilitating ‘moments of luxury’, younger consumers’ luxury consumption, as well as the integration of both future innovative technological developments and novel social media platforms within luxury branding.  相似文献

Bayesian Monte Carlo (BMC) decision analysis adopts a sampling procedure to estimate likelihoods and distributions of outcomes, and then uses that information to calculate the expected performance of alternative strategies, the value of information, and the value of including uncertainty. These decision analysis outputs are therefore subject to sample error. The standard error of each estimate and its bias, if any, can be estimated by the bootstrap procedure. The bootstrap operates by resampling (with replacement) from the original BMC sample, and redoing the decision analysis. Repeating this procedure yields a distribution of decision analysis outputs. The bootstrap approach to estimating the effect of sample error upon BMC analysis is illustrated with a simple value-of-information calculation along with an analysis of a proposed control structure for Lake Erie. The examples show that the outputs of BMC decision analysis can have high levels of sample error and bias.  相似文献
