This analysis of consumer affairs professionals in business and government describes what functions they perform, where they are employed, what education and experience is required and what their salaries are. Professional educators in the consumer field have generally ignored the career field of consumer affairs professional. Colleges and universities train consumer majors to be educators, researchers, or extension workers, but little attention is paid to the education of consumer affairs professionals for business and government. This article not only attempts to give educators in the consumer field a greater awareness of this relatively new career so that they can develop educational programs more intelligently but also attempts to make business and government more aware of what is being done in this area so they may be able to utilize the talents of consumer affairs professionals.  相似文献

December 1, 1996 a new law was implemented in Portugal to gradually reduce the standard workweek from 44 to 40 h. We study how this mandatory reduction affected employment through job creation and job destruction. There was considerable regional, sectoral and firm-size variation in the share of workers who were affected by the working hours reduction. We exploit this variation to assess the impact of the workweek reduction. We find evidence that the working hours reduction had a positive effect on employment through a fall in job destruction.  相似文献

The question of whether optimal provision of these services comes mainly from established relationships between banks and client firms or can result from arms'‐length market transactions has been the topic of considerable recent debate. This discussion has paralleled the debate in the commercial banking literature on the “specialness” of banks and whether lending can and should be relational or purely transactional. Whether the provision of investment bank services is relationship‐based or transactional is especially relevant now thanks to recent trends that have blurred the distinction between commercial and investment banks, and changed the competitive landscape for investment bank services. In their study summarized in this article, the authors examine whether investment bank‐client relationships create valuable relationship‐specific capital using stock market evidence from the period surrounding the collapse of Lehman Brothers. Specifically, they studied the effect of the Lehman collapse on companies that used Lehman for (1) underwriting equity offerings, (2) underwriting debt offerings, (3) advice on mergers and acquisitions, (4) analyst research services, and (5) market‐making services. The study addressed two specific questions. First, which investment bank services, if any, are associated with the creation of relationship‐specific capital; and second, what are the value drivers of this relationship capital? The authors report finding that companies that used Lehman as lead underwriter for public equity offerings experienced significantly negative abnormal stock returns in the days surrounding Lehman's bankruptcy announcement. By contrast, they find no significant reaction to the announcement for Lehman's debt underwriting clients or any of the other client categories they examine. While most of these investment bank services have at least the potential to create relationship‐specific capital, the authors' findings suggest that except for equity underwriting, all the other investment bank services appear to be transactional rather than relationship‐based, at least in the average case. Moreover, the authors report significant differences even among different groups of Lehman's equity underwriting clients. An equity underwriting relationship with Lehman appears to have been especially valuable for smaller, younger, and more financially constrained firms—those firms which presumably had a high degree of dependence on Lehman to access the capital market.  相似文献
