Countries and their products: A cognitive structure perspective   总被引:3,自引:0,他引:3  
This research reports on consumers’ cognitive structures for countries and their products. In-depth personal interviews identified respondents’ knowledge, beliefs, myths, and other relevant cognitions related to a diverse set of 11 countries and their products. Derived cognitive dimensions were analyzed via correspondence analysis, and the 11 countries were subsequently grouped into five sets, or cognitive categories. In addition to the empirical findings, the article introduces the concept of country equity as a new way of thinking about global brands and discusses managerial implications related thereto. He has published in theJournal of Consumer Research, Journal of Marketing Research, Journal of Marketing, and elsewhere. His articles have appeared in theJournal of Marketing, Journal of the Academy of Marketing Science, Journal of International Business Studies, California Management Review, and others. He is the coauthor of two marketing research textbooks and has published in leading marketing and social psychological journals.  相似文献

Previous empirical research indicates that corporate insiders tend to increase (decrease) their shareholdings before events that increase (decrease) firm value. More recent evidence suggests, however, that passage of the Insider Trading Sanctions Act of 1984 (ITSA) may have deterred this behavior. Our results indicate that before passage of the ITSA, insiders exploited their access to nonpublic information by selling shares before the announcement of equity issues. However, after passage of the ITSA insiders no longer displayed this behavior. We conclude the ITSA has a deterrent effect, which is more heavily concentrated on insiders at the highest level of the firm who are most visible to regulators and other market participants.  相似文献

During the Reagan administration, the federal government mandated the use of cost–benefit analysis (CBA) for regulatory decisions involving $100 million or more. While the use of CBAs has increased, less attention has been given to CBA processes involving smaller expenditures (regulatory and nonregulatory). As the federal budget tightens in the years ahead, the need to make hard decisions about these policies, programs, and technologies will increase. This paper describes a CBA process developed for the Office of Strategic Planning of the Social Security Administration; it was designed to handle small-to-moderate expenditure decisions (or for preliminary estimates of larger undertakings). A sample CBA using this process is provided, along with a discussion of the lessons that were learned from an initial application.  相似文献

In this paper we investigate the effect of golden parachute (GP) adoptions on shareholder wealth. We control for the potential effect a GP adoption has on the probability that a firm will receive a takeover bid by investigating the wealth effects for firms that are in play when the GP is adopted. We find that announcements are wealth neutral when firms are in play and wealth increasing when firms are not in play when a GP is adopted. The results suggest that GPs have no influence on the success of a tender offer, refuting the hypotheses that they either align manager and shareholder interests or that they entrench inefficient managers. The difference in the results for in-play and not-in-play firms is consistent with the hypothesis that GPs signal an increased likelihood that a firm will receive a takeover bid.  相似文献

Reduced-form price spread models have been recently utilized by Wohlgenant and Mullen, and Thompson and Lyon to evaluate the economic factors affecting the marketing margins for agricultural products. Drawing on Gardner, Heien, Buse and Brandow, Waugh, Tomek and Robinson, and others they specify alternative retail-farm price spread models and attempt to determine which best fit the data in the context of underlying theoretical rationale. This paper continues in the spirit of Wohlgenant and Mullen, and Thompson and Lyon by evaluating alternative specifications of the retail-farm price spread for white maize in South Africa. However, several important differences do remain. Wohlgenant and Mullen analyzed the price spread for beef using annual data, while Thompson and Lyon modeled the price spread for oranges using weekly data. The time period under consideration can be expected to affect the choice of model because fixed markup rules that might be evident using a short-run period of analysis (e.g., Thompson and Lyon) become untenable over the long run with underlying supply and demand shifts. In this paper, monthly data, which may be interpreted as an intermediate-run period, are used along with dichotomous supply-demand shifters. In addition, Brorsen et. al. have shown that price uncertainty affects the price spread in the marketing channels of agricultural commodities. Thus, the analysis in this paper extends the framework of Wohlgenant and Mullen, and Thompson and Lyon to include measures of price risk. Finally, like Brorsen et. al. this study pertains to the grain market, while Wohlgenant and Mullen, and Thompson and Lyon studied the marketing margin for non-storable commodities.  相似文献

Political scrutiny and earnings management in the oil refining industry   总被引:1,自引:0,他引:1  
The fortunes of the oil refining industry have historically been tied to the political process. In periods of high gasoline prices public outcry increases pressure on the political process to increase regulation, taxation, and other costs on the industry. This study explores the relationship of gasoline prices and oil firm earning with accounting earnings management of oil firms. Findings indicate that firms make accounting changes and discretionary accruals to decrease (increase) earnings in periods when gasoline prices and oil firm earnings are rising (falling).  相似文献
