ANTITRUST and COMPETITION, HISTORICALLY CONSIDERED 总被引:1,自引:0,他引:1
Although antitrust laws enjoy wide support among economists, there was almost no such support during the early years of the Sherman Act. One reason for this transformation is a change in the theory of competition. Until the 1920s most economists viewed competition as a dynamic, rivalrous process that would be stifled by antitrust laws. Once the perfect competition model–which largely ignores rivalry–was accepted, economists' opinions of antitrust grew more favorable. To the extent that antitrust interferes with rivalry and enterprise, the competitive model has very likely misdirected the profession, at least as far as antitrust policy is concerned. 相似文献

Abstract Many analysts of sustainable agriculture have given considerable attention to issues of knowledge production, but in general they have not engaged social movement theory. This neglect is addressed by examining the emergence of intensive rotational grazing as a local expression of the sustainable agriculture movement. Conceptual frameworks drawn from recent contributions to social movement theory are used to describe the cognitive praxis of graziers along technological, cosmological, and organizational dimensions. Contrary to current interpretations, which emphasize the idiosyncratic character of local knowledge in agriculture, this analysis shows that through horizontal forms of organizing and information exchange, graziers overcome the limits of their personal experience and usefully share local knowledge in networks that they have forged expressly for that purpose. 相似文献

The methodology presented here identifies an approach to accurately and economically analyze the effects on risk of various containment performance issues. Although this method facilitates the evaluation of potential containment improvements, it does so while utilizing the significant amount of information accumulated by the U.S. NRC Reactor Risk Reference Program. The use of hindsight and the acceptance of point estimate quantifications of risks allows the proposed methodology to be scrutable and understandable to the community as well as relatively simple and inexpensive to apply. A study of containment venting strategies was used to demonstrate the capabilities of the simplified containment event tree methodology. However, the methodology is flexible enough for a wide range of risk evaluations. 相似文献

Changing mortality patterns that led life expectancy in Japan to surpass Sweden’s: 1972–1982 总被引:1,自引:0,他引:1
Between 1972 and 1982, Japan caught up to and then surpassed Sweden as the country with the longest life expectancy. The contributions of different causes of death and age groups to life expectancy changes in males during this time period are examined in detail for these two countries. Even though cerebrovascular disease mortality rates remained lower in Sweden over the entire interval, the rapid gain made by Japan relative to Sweden for this cause of death was a prime factor in Japan's ending the period with a higher life expectancy. Important contributions to life expectancy improvement in Japan came from declining mortality rates in those aged 55 and older. 相似文献

The assumption of bounded utility function resolves the St. Petersburg paradox. The justification for such a bound is provided by Brito, who argues that limited time will bound the utility function. However, a reformulated St. Petersburg game, which is played for both money and time, effectively circumvents Brito's justification for a bound. Hence, no convincing justification for bounding the utility function yet exists. 相似文献
