Environmental liability and harmonization in the presence of transboundary effects and hidden assets
Henry van Egteren R. Todd Smith Andrew Eckert 《European Journal of Law and Economics》2006,22(2):143-163
Within the context of transboundary disputes, this paper seeks to determine which liability concept, negligence or strict
liability, performs better when assets are secure against foreign claims for transboundary damages. Our results indicate that,
if assets are hidden from foreign claims, strict liability will not implement the socially optimal outcome, but neither will
negligence. However, even though the socially optimal outcome is not always achieved, strict liability weakly dominates negligence.
These results suggest that the harmonization of statues that deal with transboundary pollution should be based on strict liability
not negligence.

Abstract: In a continuing quest to build and defend world markets for tobacco products, tobacco companies have long been involved in international cooperation and information‐sharing through their own international corporate networks, as well as through national and international industry trade associations. This is evidenced in tobacco industry corporate documents now freely available on the internet. In order to institute effective tobacco control policy, policy‐makers needed to become equally astute at sharing information across national boundaries and at considering the cross‐national implications of policy and legislation. The World Health Organization has been instrumental in developing the Framework Convention on Tobacco Control (FCTC), and Canada has played an important part in this effort. The FCTC contains both demand‐reduction provisions and supply‐side provisions intended to reduce tobacco use worldwide. As a signatory to the FCTC, Canada has pledged to adhere to these provisions, thereby providing Canadian public administrators with effective tools to reduce tobacco use and its associated health burden both nationally and internationally. Sommaire: En cherchant continuellement à développer et à défendre les marchés mondiaux pour les produits du tabac, les sociétés productrices de tabac sont impliquées depuis longtemps dans la coopération internationale et le partage d'informations par le biais de leurs propres réseaux de sociétés internationales et d'associations professionnelles nationales et internationales. C'est ce qui ressort des documents des sociétés productrices de tabac auxquels on peut accéder librement sur Internet. Afin d'instituer une politique efficace de contrôle du tabagisme, les décideurs politiques ont dù devenir astucieux quant au partage d'informations et à l'étude des répercussions transnationales des politiques et des lois. L'Organisation mondiale de la santé a fortement contribuéà l'élaboration de la Convention‐cadre sur la lutte contre le tabagisme (CCLCT), et le Canada a joué un rôle important sur ce plan. La CCLCT contient à la fois des dispositions relatives à la réduction de la demande et d'autres relatives à l'offre qui visent à réduire la consommation de tabac dans le monde entier. En tant que pays signataire de la CCLCT, le Canada s'est engagéà respecter ces dispositions, fournissant ainsi aux administrateurs publics canadiens des outils efficaces pour réduire la consommation de tabac et le fardeau sur la santé qui lui est associéà l'échelle nationale et internationale. 相似文献

The United States today faces a loss of influence as a world power, a reduction in American independence as a policymaker, and a decline in the standard of living on which Americans have come to depend. History teaches that nations weaker and less productive than the United States can rise to become economic powerhouses and rapidly increase their standards of living. History also teaches that nations failing to recognize their fundamental problems will inevitably decline. American politicians must face what is abundantly clear: the United States is losing ground and must act quickly to reverse its course. This White Paper outlines what must be done. Information about the nation's current status must be analyzed and communicated. Incentives to improve the level of competence in government must be provided and maintained. The emphasis of government policy must be changed to reflect broad economic and technological interests as opposed to special interests. Savings must be encouraged and increased. Infrastructure must be improved Tax laws must be modified to help bring these changes about. Economic and technological issues must be elevated to the importance they require. American thinking must reflect the new realities: that the age of leadership through military power is over, that the requirements for success in the world of the 1990s and beyond require a sound and growing economy that is internationally competitive. The US can accomplish these goals only through foundation-shaking, comprehensive, fundamental changealong the lines we propose herein.This paper is the executive summary (with minor editing modifications) of a white paper that is available from Cornell University's Johnson Graduate School of Management. 相似文献

This paper reports on the economic contributions and impact of the Small Business Innovation Research (SBIR) Program in Michigan during the first decade. The Michigan SBIR experience is examined to learn how researchers and small businesses use the SBIR Program, whether to start or strengthen businesses, how they view SBIR after a decade, and how the program has served Michigan businesses that have successfully carried out Phase I, Phase II, and Phase III SBIR projects. From the beginning of the SBIR Program, MERRA has coordinated annual SBIR conferences for Michigan companies. The MERRA staff has helped small businesses prepare suitable R&D projects and write effective SBIR proposals. Numerous SBIR awards have resulted from MERRA supportive efforts, and the MERRA small business outreach activity has kept MERRA in touch with successful firms to assist them in getting the best results from their SBIR projects and to assess progress. For this study, in-depth evaluations were made of various Michigan firms that won SBIR awards, including both mature small businesses and start-up companies to learn in what ways their SBIR experiences are parallel and in what ways they diverge. The study covers those that have used SBIR funds to diversify and add new areas of business to existing core areas. Other companies examined were created by researchers associated with universities, industry, or research organizations who utilized SBIR awards to assist in starting new businesses. Also considered were Michigan companies at different levels of development that have employed SBIR awards as seed money to perfect innovative new products for marketing. 相似文献

Four unrelated hanging deaths involving young white males, all in enlisted status in the United States military, are presented. Taken in a military context, one scene served as a suicide note equivalent with the unmistakable message of extreme defiance toward military regulations. In two cases, the elaborate attire of the decedents could have lead to the misclassification of the manner of death if investigative information had not been considered. Extensive background investigation and review of medical records in the fourth case disclosed that the victim had an eight- to ten-year history of compressing his neck to cause unconsciousness. He left an extensive suicide note in which he concluded that "hanging would be good." Each case has certain unique features, as a group, the cases all demonstrate a continuum from obvious suicide to cases where the manner of death is, at first, equivocal. 相似文献
