Substantiation of advertising claims has been a source of concern for consumerists, government and business for over a decade. The research reported in this article uses earlier studies as a benchmark for determining whether advertisers are any more willing to provide proof of advertising claims directly to consumers than they were in the 1970s. Seventy-one per cent of advertisers contacted responded to consumer requests for proof of claims made in television and magazine advertisements. However, only 21 per cent of the original requests resulted in successful substantiation. This finding parallels results obtained by Coney and Patti (1979)4 with the chief difference being fewer unsuccessful attempts at substantiation and more responses that made no attempt at substantiation. Implications for consumer education, public policy and marketing practice are discussed. 相似文献

Statistical classification methods such as multivariate discriminant analysis have been widely used in bond rating classification in spite of the limitations of the methodology. Recently, neural networks have emerged as new methods for business classification. This approach to neural networks training is to categorize a new instance as one of the predefined bond classes. Such a conventional approach has limitations in dealing with the ordinal nature of bond rating. In addition, most of the prior studies have used sample data which are evenly divided among the classes. However, the natural population in real application is usually unevenly divided among the classes. Under such circumstances, it is hard to achieve good predictive performance. As the number of classes to be recognized increases, the predictive performance decreases. In this article, to increase the predictive performance in real-world bond rating, we propose the ordinal pairwise partitioning (OPP) approach to backpropagation neural networks training. The main idea of the OPP approach is to partition the data set in the ordinal and pairwise manner according to the output classes. Then, each backpropagation neural networks model is trained by using each partitioned data set and is separately used for classification. Experimental results show that the predictive performance of the proposed OPP approach can be significantly enhanced, when compared to the conventional neural networks modeling approach as well as multivariate discriminant analysis. The OPP approach has two computation methods, and we discuss under which circumstances one method performs better than the other. We also show the generalizability of the OPP approach. © 1997 by John Wiley & Sons, Ltd. 相似文献

In May 1982, sugar import quotas were imposed after they had been discontinued for eight years. This paper examines the absolute and relative costs of the new sugar program and compares it to alternative systems of producer protection. The results indicate that the existing system is both inefficient and inequitable. The use of deficiency payments would transfer the burden of producer protection from sugar consumers to taxpayers. In addition, foreign aid should be provided directly (through taxes), rather than indirectly by means of quotas. The fact that political feasibility appears to have dominated efficiency or equity considerations means that low income consumers will continue to bear a disproportionate share of the costs of protecting domestic sugar producers and providing foreign aid. 相似文献

Consumers' and managers' perceived images of three discount department stores and a hypothetical ideal discount store were compared in this study. Results indicate that managers and consumers possess significantly different overall impressions of each store. Significant differences were also identified between the ideal amount of each attribute and the amount offered by the retailer. 相似文献

There is evidence that attractive looking workers earn more than average looking workers, even after controlling for a variety of individual characteristics. The presence of such beauty premiums may influence the labor supply decisions of attractive workers. For example, if one unit of a product by an attractive worker is more rewarded than that by her less attractive coworker, the attractive worker may put more effort into improving her productivity. We examine this possibility by analyzing panel data for individual female golfers participating in the Ladies Professional Golf Association (LPGA) tour. We found that attractive golfers recorded lower than average scores and earn more prize money than average looking players, even when controlling for player experience and other variables related to their natural talents. This finding is consistent with the notion that physical appearance is associated with individual workers' accumulation of human capital or skills. If the human capital of attractive workers is at least partly an outcome of favoritism toward beauty, then the premium estimates obtained by previous studies may have been downwardly biased.

Total factor productivity growth of the five ASEAN founding members is estimated by decomposing total factor productivity growth into technical efficiency and technological progress. By using the stochastic frontier model with individual‐specific temporal pattern of technical efficiency for the period of 1981–2003, the present paper identifies the unique temporal pattern of productivity changes in each country, to analyze the relationship between country characteristics and the inherent efficiency and productivity changes. The empirical results indicate that over the study period, growth in Singapore and Malaysia was largely driven by both technological progress and input accumulation, whereas growth in Thailand was induced by an improvement in technical efficiency and through input accumulation. 相似文献
