This article examines the role of the discount rate in makingdecisions that will have significant implications for the environment.The authors begin by providing a rationale for discounting ingeneral and by describing the main factors that determine thediscount rate. These factorsthe private and social ratesof time preference, the opportunity cost of capital, risk anduncertainty, and the interests of future generationsallhave an environmental dimension. The article goes on to examinethat dimension and to explore the connections between the choiceof the discount rate and environmental concerns, such as excessiveexploitation of natural resources, inadequate investment inconservation, and insufficient attention to the irreversibleloss of certain environmental resources. The authors conclude that, in general, environmental concernsare not best addressed by lowering the discount rateanaction that might have both benefits and costs for the environment.A more promising course would be to incorporate a criterionof sustainability into certain aspects of decisionmaking. Howsuch a criterion could be made operational is touched upon butnot developed in this article. 相似文献

This paper examines the macroeconomic sources of risk priced in the UK stockmarket between 1983 and 1990 using monthly data on 840 stocks to form both beta-sorted and market value sorted portfolios using the methodology proposed by Chen, Roll and Ross (1986) and Chan, Chen and Hsieh (1985) for the US. We find that several intuitively plausible macroeconomic variables were priced over this period using the beta sorted portfolios and that once these variables are included there is little role for the return on the market. However, when the market value sorted portfolios were used only inflation and a measure of equity market 'expense' relative to gilts was priced; furthermore with the market value sorted portfolios a role for the market return was found. 相似文献

Using both marketwide and firm-level illiquidity measures of the stock, bond, and credit default swap markets, we find that comovements of illiquidity across markets increase significantly during the recent global financial crisis. Moreover, the degree of comovement remains significantly higher in the postcrisis period and regulatory period than in the precrisis period. Specifically, the distribution of firm-level comovements is notably different before and after the crisis (e.g., a much larger portion of firms with positive pairwise correlations between illiquidity measures in the postcrisis period than in the precrisis period). Our results provide suggestive evidence of the financial crisis effects and the subsequent postcrisis regulations on the comovements of illiquidity across markets. 相似文献
