Using data covering every child born in California from 1961 to 2000, Fryer and Levitt (2004) find that in the 1960s, the differences in name choices by blacks and whites were relatively small, but that a profound shift began among blacks in the mid-1970s toward more distinctively black names, especially among blacks in racially isolated neighborhoods. As an extension of Fryer and Levitt (2004), this study uses data on the names of about 1,300 white children born over the four-year period from 1997 to 2000 and living in a segment of a Metropolitan Statistical Area in the Deep South, and finds that use of combination first names—largely based on combinations of single names included among the names of high-end white children from Fryer and Levitt (2004) and Levitt and Dubner (2005)—is significantly more prevalent among high-end white children than it is among low-end white children. Unlike the data described in Fryer and Levitt (2004), which support an Identity Model wherein distinctively black names result from the Black Power movement that encouraged blacks to “accentuate and affirm black culture and fight the claims of black inferiority,” the present study suggests that high-end parents may use the combination first name convention to increase the likelihood of the child’s future success in various partnership markets, such as dating, marriage and business-partnership markets.  相似文献

The challenge of global talent management is critical to firm success. Even with the global economic slowdown of 2008 and 2009, there are continuing challenges in attracting, managing, and retaining talent, especially in the developing regions of the world where economic activity has outpaced the availability of skilled employees. To examine this situation, we develop and test a model of talent management across 28 Indian firms involving 4811 professional-level employees. The intrinsic rewards experienced are a critical element in employee retention, satisfaction with the organization, and career success. We explored four antecedents of intrinsic rewards: the social responsibility of the employer, pride in the organization, manager support, and performance management (PM). We found support for the importance of intrinsic rewards as a mediating variable, as well as for the moderating role of certain hygiene factors. Our research suggests multinational, international, and national employers may have non-pecuniary mechanisms to promote retention and employee satisfaction, even in challenging labor market environments. We conclude by proposing implications for research and global HRM practices.  相似文献

Capitalism is the most efficient system for solving problems and for advancing human welfare. Yet it faces opposition both from intellectuals and those with vested interests in big government. If business leaders would push for ‘liberate to stimulate policies’, they might succeed in creating a freer tomorrow and solving more of humanity's problems.  相似文献

Marketers are now willing to go anyplace they can find a captive audience to espouse the virtues of their products. The success of the “buzz” marketing approach is linked to the consumer being lured into doing the advertising by spreading the message to others. This study compares students’ responses to a traditional advertising and a buzz approach. Using a factor analysis to identify variables, the results show that subjects perceive a buzz approach to be more influential than a traditional advertising. However, they do not perceive a buzz approach to be authentic. This finding is consistent with practitioners’ argument that, although a buzz approach may be effective in the short-term, once consumers recognize its selling intent, the program may have a “boomerang effect.”  相似文献

Abstract. During the last decade, many Western economies reformed their welfare systems with the aim of activating welfare recipients by increasing welfare‐to‐work programmes (WTWP) and job‐search enforcement. We evaluate the short‐term effects of three important German WTWP implemented after a major reform in January 2005 (‘Hartz IV’), namely short training, further training with a planned duration of up to three months and public workfare programmes (‘One‐Euro‐Jobs’). Our analysis is based on a combination of a large‐scale survey and administrative data that is rich with respect to individual, household, agency level and regional information. We use this richness of the data to base the econometric evaluation on a selection‐on‐observables approach. We find that short‐term training programmes, on average, increase their participants' employment perspectives. There is also considerable effect heterogeneity across different subgroups of participants that could be exploited to improve the allocation of welfare recipients to the specific programmes and thus increase overall programme effectiveness.  相似文献

We show that some care is needed when inferring true unconditional correlations from observed conditional correlations, which is a frequent problem in empirical finance and elsewhere. We give a general formula for the relationship between the two and demonstrate its importance in the context of the bivariate t-distribution.  相似文献

This paper explores asset pricing in economies where there is no direct insurance against idiosyncratic risks but other assets can be used for self-insurance, subject to exogenously-imposed borrowing limits. We analyze an endowment economy, based on Huggett (1993) [11], both with and without aggregate risk. Our main innovation is that we obtain full analytical tractability by studying the case with “maximally tight” borrowing constraints. We illustrate by looking at riskless bonds, equity, and the term structure of interest rates, and we show that the model can reproduce many features of observed asset prices when idiosyncratic risks are quantitatively reasonable.  相似文献
