The effect of 1980s tort reform legislation on general liability and medical malpractice insurance 总被引:1,自引:1,他引:0
W. Kip Viscusi Richard J. Zeckhauser Patricia Born Glenn Blackmon 《Journal of Risk and Uncertainty》1993,6(2):165-186
A large number of states adopted tort reforms in the mid-1980s to limit the dramatic surge in insurance losses and premiums. Evidence based on liability insurance data by state indicates that these reforms substantially influenced general liability insurance. The levels of losses, premiums, and loss ratios (a measure of insurance profitability) all reflected the impact of the reforms. The large-scale reform efforts in 1986 were particularly influential. Medical malpractice insurance was much less sensitive to the reform efforts. 相似文献

Much debate over the years has centered around whether there was ever a “golden past” for the introductory sociology textbook,
when high quality books influenced the development of scholarship and thinking. Some empirical evidence is added to this debate
through an analysis of the citations to introductory sociology textbooks in all the articles and research notes appearing
in theAmerican Journal of Sociology, theAmerican Sociological Review, andSocial Forces from 1960 to 1969 and from 1984 to 1993. The data show that, although seldom cited in recent journals, introductory sociology
textbooks were often cited in the earlier period. The article concludes with some thoughts about why introductory sociology
textbooks have had a declining influence on scholarship. 相似文献

To quantify the health benefits of environmental policies, economists generally require estimates of the reduced probability of illness or death. For policies that reduce exposure to carcinogenic substances, these estimates traditionally have been obtained through the linear extrapolation of experimental dose-response data to low-exposure scenarios as described in the U.S. Environmental Protection Agency's Guidelines for Carcinogen Risk Assessment (1986). In response to evolving scientific knowledge, EPA proposed revisions to the guidelines in 1996. Under the proposed revisions, dose-response relationships would not be estimated for carcinogens thought to exhibit nonlinear modes of action. Such a change in cancer-risk assessment methods and outputs will likely have serious consequences for how benefit-cost analyses of policies aimed at reducing cancer risks are conducted. Any tendency for reduced quantification of effects in environmental risk assessments, such as those contemplated in the revisions to EPA's cancer-risk assessment guidelines, impedes the ability of economic analysts to respond to increasing calls for benefit-cost analysis. This article examines the implications for benefit-cost analysis of carcinogenic exposures of the proposed changes to the 1986 Guidelines and proposes an approach for bounding dose-response relationships when no biologically based models are available. In spite of the more limited quantitative information provided in a carcinogen risk assessment under the proposed revisions to the guidelines, we argue that reasonable bounds on dose-response relationships can be estimated for low-level exposures to nonlinear carcinogens. This approach yields estimates of reduced illness for use in a benefit-cost analysis while incorporating evidence of nonlinearities in the dose-response relationship. As an illustration, the bounding approach is applied to the case of chloroform exposure. 相似文献

This paper reports the results of interdisciplinary research extending the work of Mather and Peasnell (1991) reported in an earlier issue of this journal. Mather and Peasnell conducted an empirical analysis of the economic circumstances surrounding decisions to capitalize brands. This study investigates the managerial implications of periodically assessing and capitalizing the value of brands. Exploratory interviews were conducted with the key players in brand valuation activity, namely marketing and finance officials in brand-valuing companies and two senior personnel in the leading international brand-valuing agency. The recent inception of brand valuation in the accounts of several strong branded British companies provides an excellent research opportunity to explore a relatively novel managerial activity and its internal implications. These implications are reviewed under the headings: planning and control, the accounting/marketing interface, authorization of brand-related expenditure and brand-related decision making. An important finding of the study is that, while the original impetus for brand valuation came from balance sheet considerations, other unforseen managerial advantages are now widely perceived to accrue from brand valuation. The majority of current brand valuation activity appears to be driven more by management information needs, which are served by the evaluation phase of the exercise, than by a desire to capitalize brands in the published statements. 相似文献

State governments exercise significant powers to regulate the economic and social activities of resident aliens. We review the laws of the six leading states of immigrant settlement regulating access of noncitizens to 23 occupations, updating existing studies from 1946–77. Citizenship requirements for these occupations have plummeted, a change we attribute to federal court decisions, advisory opinions of state attorneys general, and state legislative and administrative action. There are numerous additional citizenship requirements in the statutes of the six states, although these appear to be poorly enforced. The authority of states to regulate their political communities is the most important remaining constitutionally valid basis of citizenship requirements. States define their political community broadly, leading to questionable exclusions of noncitizens from important activities. 相似文献
