This paper uses a two-sector, two-period,spatial model of groundwater usage withstochastic surface water supply to illustratethe
potential for the suboptimal management ofthe timing of groundwater uses. A ``timeprofile externality' is said to exist when thetiming of groundwater extraction by one set ofusers
impacts on the time profile of wateravailability to another set of users. Theexistence of the time of use externalitydepends
on the presence of importantdifferences in the preferences between thecontrol and non-control sectors. It alsodepends on the
absence of the markets thatwould internalise these differences. Oneimportant implication of the existence of suchexternalities
is that they can inducesub-optimal insurance investments in the formof water storage capital, i.e., unnecessarysurface water
reservoirs. 相似文献

We analyze the potential competitive effects of the proposed Basel II capital regulations on US bank credit card lending. We find that bank issuers operating under Basel II will face higher regulatory capital minimums than Basel I banks, with differences due to the way the two regulations treat reserves and gain-on-sale of securitized assets. During periods of normal economic conditions, this is not likely to have a competitive effect; however, during periods of substantial stress in credit card portfolios, Basel II banks could face a significant competitive disadvantage relative to Basel I banks and nonbank issuers. 相似文献

New Evidence of the Impact of Dividend Taxation and on the Identity of the Marginal Investor 总被引:2,自引:0,他引:2
This paper examines the impact of a major change in dividend taxation introduced in the United Kingdom in July 1997. The reform was structured in such a way that the immediate impact fell almost entirely on the largest investor class in the United Kingdom, namely pension funds. We find significant changes in the valuation of dividend income after the reform, in particular for high-yielding companies. These results provide strong support for the hypothesis that taxation affects the valuation of companies, and that pension funds were the effective marginal investors for high-yielding companies. 相似文献

This article reports the results of a study of innovation and product development at 245 manufacturing sites in the UK and Germany. It examines the relationship between design and performance and the competitiveness of the UK and Germany in design and manufacturing. Overall, few sites reached "world-class" standards - 9% in Germany and 3% in the UK, although many sites were not far below these standards. 相似文献

The effects of group problem-solving method and problem-situation complexity on attempts at implementing group solutions were investigated in a laboratory-field setting. Group members were supervisory nurses from various organizations, who were randomly assigned to three groups in a balanced research design which included three group decision-making processes and three levels of problem-situation complexity in implementation. The dependent variable was the number of attempts at implementing group-derived solutions in home organizations. The results showed that structure in group decision-making processes led to increased rates of implementation attempts at all levels of problem-situation complexity. There was a significant complexity-by-process interaction effect among the decision-making processes, which supports the conclusion that the type of group decision-making process and the problem-situation complexity should be considered in order to optimize the number of implementation attempts.g 相似文献

The New York State Environmental Externalities Cost Study and computerized externality model (EXMOD) are used to examine the specification of methods design and application factors in the computation of electricity externalities. We report the sensitivity of externality estimates with alternative specifications for 15 different factors in the analysis, including the selection of facility type, site, and operating characteristics; air emission assumptions and air modeling procedures; dose-response assumptions; economic valuation assumptions; and other modeling procedures and assumptions. Many of the factors that most influence externality computations can be well specified in the analysis, such as the facility type, age, characteristics, emission rates, whether there is SO2 trading, and the inclusion of long range impacts. Most significant among the factors for which there remains significant scientific uncertainty are the selection and application of air dispersion models, selection of air pollution thresholds for health impacts, reduced life span risks associated with ozone exposure and with long-term exposure to PM10, values for CO2 damages, and the value to be applied to increased risks of reduced life span for individuals age 65 or older. 相似文献
