Environmental social controls (ESCs) such as mandatory disclosure, regulations, subsidies, and stakeholder opinion are intended to improve firm environmental performance. This paper reports ESC importance to Australian financial managers in making capital investment decisions. A decision‐making experiment showed managers to be most responsive to stakeholder opinion (42 per cent), followed by subsidization (26 per cent) and regulatory cost (22 per cent). Mandatory disclosure has very little influence (10 per cent). ESC interaction effects are limited so coordination of ESC policy is not a primary concern. High degrees of managerial self‐insight suggest policy changes would be enhanced by close consultations with the managers involved. 相似文献

Scientific assessment panels are playing increasingly influential roles in national and international policy formation. Although they typically appeal to the standard of journal peer review as their quality control criterion, there seems to be confusion about what peer review actually does. It is, at best, a necessary condition of reliability, but not a sufficient condition. There is also the problem that assessment panels may be biased in favor of one side or another when evaluating areas in which the science is unclear. In this paper I argue that additional checks and balances are needed on the information going into scientific assessment reports when it will be used to justify major policy investments. I propose two new mechanisms to bias-proof the outcome: an Audit Panel and a Counterweight Panel. The need for such mechanisms is discussed with reference to the "hockey stick" debate in climate change. 相似文献

We have occasionally encountered patients on nonsteroidal antiinflammatory drugs (NSAIDs) in whom double contrast barium studies revealed persistent flattening and stiffening of the distal greater curvature of the stomach. We therefore performed a study to determine the frequency of this finding in patients with NSAID-related gastropathy. Twenty-one cases of erosive gastritis, gastric ulcers, and/or gastric scarring associated with a known history of NSAID use were reviewed by two radiologists who made a joint decision regarding the presence or absence of greater curvature antral flattening. This finding was seen radiographically in five of the 21 patients (24%). Four of the five patients with antral flattening had associated erosions or ulcers in the gastric antrum. The remaining patient had antral flattening as an isolated finding. Our experience suggests that flattening of the greater curvature of the distal antrum, particularly if associated with erosive gastritis or gastric ulcers, is a useful radiologic sign of NSAID-related gastropathy. 相似文献

Expressions are given relating municipal bond coupon rates to underwrite profit margins and the market yield. These expressions are applied to the examination of net interest rates, net present value and the cost of capital of serial bond issues. The conditions which must be satisfied so that a decrease in net interest rate corresponds to an increase in net present value (hence a decrease in the cost of capital to the issuer) are presented. 相似文献

This paper finds necessary and sufficient conditions on the stochastic structure of asset returns for portfolio choice to be equivalent to choice among a limited number of mutual funds of assets, independent of investors' preferences. This type of separation result is central to modern financial theory and the distributions which satisfy these conditions, the separating distributions, form the underlying basis for much of this theory. 相似文献
