The retail food market in Edmonton, Alberta represents an unusual market to study. The basic problem inherent in this metropolitan market area of 500,000 people, is the dominance of a single retail food chain whose food sales represent up to 65 percent of total food sales. Conventional economic theory would normally lead to the conclusion that market performance would be improved by a direct attack on the structure of the market which in turn would involve the absolution of a highly successful retail operation. However, the application of monopoly anti-trust laws was certainly not an alternative available to the research team, even if it was considered to be a feasible solution to the problem. Therefore an attempt was made by the authors to observe the impact of improved consumer market information on corporate performance. The following article documents the research and leads towards a time honored conclusion that additional market information would improve consumer welfare in a meaningful manner. 相似文献

Do the consumer advocates, such as Nader, have a real constituency? Where do they get their support? This study, based on a nationwide sample, investigated the extent of support for Ralph Nader and his program, and its sources. Nader was found to have substantial support, a major portion of it consisting of middle-income political liberals. Those supporting Nader were found to be active complainers and supporters of other political and social causes, suggesting that support for Nader is part of a broader pattern of activisim. 相似文献

In this paper, we develop a paleoeconomic model of the co-evolution of economic specialization and encephalization—the common physiological measure of intelligence as reflected by brain mass relative to total body mass. Our economic analysis links ecological and social intelligence theories of increased encephalization in early hominins through a model in which both economic and ecological feedbacks jointly determined the evolutionary incentives. We focus on degrees of specialization affected by coordination costs with and without market exchange. Our results suggest encephalization would be a process characterized by diminishing returns to behavioral advances. In terms of the long-running debate in economics over whether specialization increases or decreases intelligence, our results suggest from an evolutionary perspective the answer depends on economic/social institutions and how these influence ecological interactions. 相似文献
