An experiment tested young adults' memory for advertising slogans that either stated a strong claim directly or only implied the same claim by stating it in a much weaker form. Several advertising slogans were inserted into a story. There were two versions of each slogan, asserted and implied. The asserted version made a claim very directly and strongly (e.g.Alka-Seltzer stops common aches). The implied version only suggested the stronger claim (e.g. Alka-Seltzer helps lessen common aches ). Subjects read the story, which contained one of the two versions of each ad. After subjects finished reading the story, they were asked to recall all the brands and products. Then they performed a multiple choice task testing memory for the content of the advertising claims. While results showed no difference on the recall task, subjects on the multiple choice task frequently falsely recognized implied claims as asserted but seldom the reverse. Although they correctly recognized more asserted than implied claims, they were more confident in their correct memory for the implied claims. Results were applied to the problem of deceptive advertising. 相似文献

Given the interplaying tendencies of economic decline, social instability, and environmental depletion, any transition towards sustainable development faces a challenging task. To successfully cope with this complexity requires transition management. Integrated approaches for supporting sustainability transitions have been elaborated in the last years. Future studies and scenario construction are regarded as essential components in these approaches. However, the related studies in this field have focused either on a specific type of transition process, or on decision support in a different contextual process, or on a specific function of scenarios. Thus, an evaluation of the wide range of viewpoints on the functions of scenarios with respect to the requirements for transition management is still missing. In this paper, we systematically elaborate upon the functions for transition management that scenarios can fulfil. The developed concept is applied to five empirical scenario studies supporting transition processes on the national, regional and local level in Switzerland. The paper contributes to the development of a functional methodology of transition support, providing initial guidelines for answering the question of which method is appropriate for what type and phase of a transition process. 相似文献

The performance of contrarian, or value strategies – those that invest in stocks that have low market value relative to a measure of their fundamentals – continues to attract attention from researchers and practitioners alike. While there is much extant evidence on the profitability of value strategies, however, most of this evidence pertains to the US. In this paper, we provide a detailed characterisation of value strategies using data on UK stocks for the period 1975 to 1998. We first undertake simple one-way and two-way classifications of stocks in which value is defined using both past performance and expected future performance. Using sales growth as a proxy for past performance and book-to-market, earnings yield and cash flow yield as measures of expected future performance, we find that that stocks that have both poor past performance and low expected future performance have significantly higher returns than those that have either good past performance or good expected future performance. Allowing for size effects in returns reduces the value premium but it nevertheless remains significant. We go on to explore whether the profitability of value strategies in the UK can be explained using the three factor model of Fama and French (1996). Broadly consistent with the results for the US, we find that using the one-way classification the excess returns to almost all value strategies can be explained by their loading on the market, book-to-market and size factors. However, in contrast with the US, using the two-way classification there are excess returns to value strategies based on book-to-market and sales growth, even after controlling for their loading on the market, book-to-market and size factors. 相似文献

In this paper an extensive review of the theoretical and applied literature on natural resource accounting (NRA) is provided. The review begins by explaining the economic theory that underpins NRA, contrasting welfare and sustainability as policy goals, and presenting various distinct conceptions of national income. The state of play regarding official revisions to the system of national accounts (SNA) with respect to natural resources and the environment is presented and controversial areas are highlighted. Finally, the economic literature on proposed revisions, and applied studies that have proceeded using these methods, is summarised and critiqued. We argue that much of the literature proceeds with weak conceptual foundations, and that typical case studies produce results that are ambiguous in interpretation. Moreover, we highlight fundamental tensions between economic theory and national accounting methodology, and conclude that one outcome of this has been the insufficient attention paid by economists to the revisions to the SNA; instead devoting time and effort to 'freelance' NRA case studies utilising sometimes ad hoc methods from the economic literature. 相似文献

Most foodstuffs have quality attributes that are difficult to determine prior to purchase. Thus quality assurance is an inherent problem in food exporting. Private quality assurance can succeed if exporters can credibly signal that they have much to lose from cessation of purchases. If exporters do not provide credible quality signals, and foreign importers judge food quality according to country of origin, honest exporters can suffer negative spillovers from others' cheating under either government or private quality assurance. For both economic and political reasons, the best choice between government and private quality assurance will differ between foods and importing countries. 相似文献

The objective of this study is to determine if there are important size and industry effects on financial performance of agricultural cooperatives. The performance of 43 dairy, food, grain, and farm supply cooperatives in the U.S. was analyzed over the period 1970-1987 using financial ratios derived from accounting data. The analysis revealed significant size and industry effects. Large regional cooperatives are more efficient in utilizing their assets to generate sales, while small regional cooperatives have higher profitability. The findings suggest that the emphasis on growth may not always produce beneficial results among agricultural cooperatives. Among the four industries studied, the dairy regional cooperatives appear to be the strongest performers, while the food marketing cooperatives are characterized by the lowest performance measures. Since both dairy and food cooperatives engage in value-added processing, this difference in performance makes it difficult to reach clear conclusions about possible advantages of disadvantages or vertical integration relative to traditional cooperative activities. Trend analysis indicates that the profitability of the agricultural cooperatives in all industry and size categories declined in response to the downturn in U.S. agriculture after 1980. While the decline in profitability was at similar rates for both large and small cooperatives, the variation of efficiency and leverage was in opposite directions. Large cooperatives may be expected to continue improving their asset utilization without relative improvement in profitability, and increasing the level of their debt in relation to equity. 相似文献
