The Nader case highlights the related problems of airline “overbooking” and passenger “no shows,” and raises the question of what public policy should be in this area. The paper analyzes the efficiency and equity aspects of Nader's attempt to eliminate overbooking. It also focuses attention on the interplay of litigation and regulation as instruments of economic policy change. 相似文献

This paper describes a study that assesses some changes in nutrition labels resulting from provisions of the Nutrition Labeling and Education Act of 1990 (NLEA). Type of nutrition label, nutritional value, and presence (absence) of a nutrition “warning” are tested in a between subjects experimental design. Results indicate that additional nutrition information recommended by the NLEA can significantly affect nutrition attitudes, perceptions, and self-reported product purchase likelihood. 相似文献

Front‐of‐package (FOP) nutrient content claims are often used by food manufacturers to promote the nutrition levels of their products. In this research, two studies examine the influence of the numerical format (either percentages or absolute numbers) presented on FOP‐reduced nutrient content claims and the moderating influence of consumers' numeracy levels (i.e., consumers' ability to interpret numbers). Low numerate consumers are more strongly influenced by the label's numerical format, but results differ across nutrition attributes linked to cardiovascular disease risk. For saturated fat, low numerate consumers had more favorable evaluations of the product that had a label presented in a percent format compared to an absolute unit format. In contrast, the moderating effect of numeracy had little effect on the format of reduced sodium claims. Implications are offered for policymakers, consumer researchers, and food manufacturers . 相似文献

In recent years, alcohol-related problems on college campuses have been well documented. This research examines how two different alcoholic beverage health warnings placed on the label of a fictitious brand of beer influence alcohol-related risk perceptions, attitudes and intentions, and characterizations of problem-drinking behaviors of binge and non-binge drinkers in Australia and the United States. The consumer welfare implications of our findings, which show that the dependent measures are influenced by both main and interaction effects, are discussed. 相似文献

We characterize the conditions under which efficient portfolios put small weights on individual assets. These conditions bound mean returns with measures of average absolute covariability between assets. The bounds clarify the relationship between linear asset pricing models and well-diversified efficient portfolios. We argue that the extreme weightings in sample efficient portfolios are due to the dominance of a single factor in equity returns. This makes it easy to diversify on subsets to reduce residual risk, while weighting the subsets to reduce factor risk simultaneously. The latter involves taking extreme positions. This behavior seems unlikely to be attributable to sampling error. 相似文献
