By comparing the top executives of 1980's Fortune 100 companies with the top brass of firms in the 2001 list, the authors have quantified a transformation that until now has been largely anecdotal. A dramatic shift in executive careers, and in executives themselves, has occurred over the past two decades. Today's Fortune 100 executives are younger, more of them are female, and fewer were educated at elite institutions. They're also making their way to the top more quickly. They're taking fewer jobs along the way, and they increasingly move from one company to the next as their careers unfold. In their wide-ranging analysis,the authors offer a number of insights. For one thing, it has become clear that there are huge advantages to working in a growing firm. For another, the firms that have been big for a long time still provide the most extensive training and development. They also offer relatively long promotion ladders--hence the common wisdom that these "academy companies" are great to have been from. While women were disproportionately scarce among the most senior ranks of executives in 2001, those who arrived got there faster and at a younger age than their male colleagues. Perhaps the career hurdles that women face had blocked all but the most highly qualified female managers, who then proceeded to rise quickly. In the future, a record of good P&L performance may become even more critical to getting hired and advancing in the largest companies. As a result, we may see a reversal of the usual flow of talent, which has been from the academy companies to smaller firms. It may be increasingly common for executives to develop records of performance in small companies, or even as entrepreneurs, and then seek positions in large corporations.  相似文献

Knowledge transfer in an innovation simulation model   总被引:1,自引:0,他引:1  
To understand the development of innovation processes in these knowledge-driven economies, one needs to focus on underlying processes of creating and sharing new knowledge. In this paper, an evolutionary simulation model is used to achieve some insights into these innovation processes. The model is based on the one hand on rules about market performance, investments and R&D strategies, and on the other hand on a model concerning knowledge creation (the ability of firms to create knowledge through intramural R&D efforts and the ability to discover and absorb new developments from basic academic research and competitors) and knowledge transfer based on an exponentionally expanding pool of (not necessarily new) knowledge of innovations in the own sector, but also from external sources. It is demonstrated that the imitative firm can be economically more successful but this strategy may prove to be superior only after a long time span.  相似文献

For the sequences of independent identically distributed random variables with continuous distributions, we provide the optimal upper bounds for the increments of order and record statistics under condition that the values of future order statistics and records are known. The bounds are expressed in terms of quantiles and absolute moments centered about the quantiles of the parent distribution. We also describe the distributions which approach the bounds with arbitrary desired accuracy.The second author was supported by the Polish State Committee for Scientific Research (KBN) under Grant 5 P03A 012 20Received November 2003  相似文献

This paper examines whether fair value adjustments included in other comprehensive income (OCI) predict future bank performance. It also examines whether the reliability of these estimates affects their predictive value. Using a sample of bank holding companies, we find that fair value adjustments included in OCI can predict earnings both 1 and 2 years ahead. However, not all fair value-related unrealized gains and losses included in OCI have similar implications. While net unrealized gains and losses on available-for-sale securities are positively associated with future earnings, net unrealized gains and losses on derivative contracts classified as cash flow hedges are negatively associated with future earnings. We also find that reliable measurement of fair values enhances predictive value. Finally, we show that fair value adjustments recorded in OCI during the 2007–2009 financial crisis predicted future profitability, contradicting criticism that fair value accounting forced banks to record excessive downward adjustments.  相似文献

Family satisfaction and social networking leisure   总被引:1,自引:0,他引:1  
The purpose of this study was to explore the bidirectional relationship between the use of social networking sites (SNS) for leisure, and family and leisure satisfaction. The sociotechnological model served as a sensitising theoretical framework for this study. Seven families (22 individuals) took part in group and individual interviews. The data obtained from interviews were analysed using constant comparative method. The results showed that influences of SNS on satisfaction with family leisure and family satisfaction varied: the use of SNS helped families to build enjoyable family leisure, stay connected with family members and increase a sense of belonging. In some cases, however, it also decreased the amount of time spent with family, lowered attention during face-to-face interactions, provided opportunity for negative comparisons and caused concerns about the development of social skills among youth. In turn, family relationships and satisfaction with family life influenced the way family members used SNS for leisure. Some participants increased the use of SNS during times of family conflict in order to seek support and as a way to distract themselves from unpleasant thoughts. Others limited their use of SNS due to lack of interest in social pursuits and to avoid sharing information about family conflicts.  相似文献

Summary.   We present a simple neoclassical life-cycle model in continuous time, in which the effects of endogenous labor supply, uncertain lifetime, and family composition on consumption and income profiles are jointly analyzed. Due to a parsimonious specification, analytical solutions for consumption growth are available for constant intertemporal elasticity of substitution preferences. Without relying on borrowing constraints, the model can generate a hump in the consumption profile, and a comovement of consumption and income during working life.

The goal of this study was to examine leisure time physical activity (LTPA) among Latina women and to determine factors influencing their LTPA participation. The ecological model was employed as a theoretical framework in order to examine attitudes, social support, and constraints affecting physical activity. Surveys and in-depth interviews were used to collect data. Results showed that although women's LTPA participation was low, they had positive attitudes toward LTPA, and they believed they had high levels of support for LTPA. The most often mentioned constraints included lack of child-care and lack of time. Attitudes toward LTPA, social support for LTPA, and certain constraints were significant predictors of LTPA participation. Results of the in-depth interviews complemented the survey data.  相似文献

In this paper, we present new evidence for the effect of changes in annuity prices on the decision to annuitize. We exploit an unprecedented change in policy in several Swiss occupational pension plans. There is an implied 8 percent reduction in the rate at which retirement capital is translated into an annuity, and this represents a net present value loss of CHF 18,500 (around US$ 20,000). To estimate the impact of this change, we use data from companies that changed their prices and from one large company that did not. We find that the price change reduces the propensity to annuitize among affected individuals by 16.8 percentage points.  相似文献

The growth of online daily deal price promotions and the resulting consumer nonredemption of daily deal coupons is worthy of understanding from a psychological lens of nonconsumption. Whereas there is an emerging literature on daily deals and established literature on barriers to redemption, there exists a gap in where this scholarship intersects. This study provides a conceptual model explaining why consumers purchase daily deal coupons and do not redeem them. We explain consumers’ reasons for buying a daily deal upfront along with their reasons for not using it from theoretical lenses of reasons theory and social motivations theory. On testing the model empirically with qualitative and deepening insight via quantitative methods, the findings reveal that reasons for purchasing daily deals are rooted in individual consumer-level factors (i.e., price-consciousness, buying impulsiveness, and susceptibility to interpersonal normative influence). Further, reasons for nonredemption are explained by contextual elements of the daily deal (i.e., offer distinctiveness, the total number of daily deals sold, restrictions on using the deal, and low discount size). Our findings suggest that post-purchase regret ultimately explains a key reason deals go unused. Marketing implications are offered in the areas of characteristics of daily deal offers.  相似文献
