Developments in environmental reporting in Denmark in the 1990s are described and also some interesting legal developments regarding the new Danish law requiring approximately 2000 companies to produce environmental reports. Some tentative speculations are offered about future directions for environmental reporting in Denmark and elsewhere. 相似文献

This paper examines the relationship between the passage of six types of corporate antitakeover provisions (supermajority, classified boards, fair-price, reduction in cumulative voting, anti-greenmail and poison pills) and stockholder wealth. Our event study from a sample of 381 firms that adopted 486 antitakeover provisions in the 1984 to 1988 period indicates a strongly negative effect on stockholder wealth, supporting the management entrenchment view of the antitakeover provisions. Moreover, the empirical results of this paper indicate that the market reacts equally negatively to both non-operating provisions that require stockholder approval and to operating provisions that do not require stockholder approval. However, separate analyses of the antitakeover provisions provide some support for the argument that stockholders discriminate between individual provisions. 相似文献

This study explores the effects of consumer knowledge on respondents' evaluations of both known and unknown brands that include either a 2-year or a 20-year warranty. Both experts and nonexperts evaluated warranty as more important than brand name in their product quality decision. Warranty length was positively correlated with product quality perceptions for both known and unknown brands. With the unknown brand, nonexperts perceived significant improvement in product quality when the warranty length was increased from 2 to 20 years. For the known brand, nonexperts perceived little difference in quality for the two warranty lengths. Experts indicated no significant differences in perceived quality, given the four brand/warranty-length conditions. The results indicate that warranty length is most heavily weighted as a cue to product quality when consumers are not highly knowledgeable, and the brand name is not well known. © 1996 John Wiley & Sons, Inc. 相似文献

A major thrust of the Magnuson-Moss Warranty Federal Trade Commission Improvement Act (MMWA) passed by Congress in 1975 is to make warranties “easy to read and understand.” This study examines readability levels for 121 warranties in ten categories of consumer durables. The warranties analyzed are found to require readability levels beyond what most Americans have attained. Limited warranties require significantly higher readability levels than full warranties. Results suggest the MMWA, since passage in 1975, may have increased the number of limited warranties and the difficulty of reading level. 相似文献

This paper surveys and compares the literature on the ‘new’ institutionalism (North, Williamson, etc.) with that of the ‘old’(Veblen, Commons, Mitchell). A criterion for distinguishing these two schools is suggested, along with criticisms of the limitations of each. The ‘new’ institutionalism is associated with methodological individualism and the idea that the individual should be taken as given. Particular attention is paid to ‘new’ institutionalist treatments of markets and firms. The paper moves on to examine some ‘old’ institutionalist criticisms of ‘economic man’ as well as some negative features of the ‘old’ institutionalism. On the positive side, the latter is seen to have an ‘evolutionary’ dimension, related to modern work in the area of technological change. 相似文献

Experience has shown that a Distributed Control System (DCS) can provide enhanced process monitoring and control capabilities, as well as system self-diagnostics, that permit increased safety of process operations. However, this enhanced safety does not come about automatically with the installation of a DCS. The complexity and versatility of the DCS can introduce new failure scenarios leading to process upset and potential relization of process hazards. This paper reviews some novel considerations that should be taken into account when conducting process hazards reviews on facilities controlled by a DCS. 相似文献
