The growing need for organ and tissue transplants has led a number of states to enforce a policy that views a donor's declared intent to be an organ donor as legally binding. This allows health officials to harvest organs without the permission of the next of kin. Legally binding consent is controversial because of concerns that it may anger family members, lead to negative publicity, and discourage potential donors. We use interviews and a pooled time-series data set of cadaveric donation rates in U.S. states to evaluate the effectiveness of this policy. Our research indicates that enforcement of legally binding consent has marginally increased cadaveric donations while not significantly affecting donor registration. We also find evidence that the effect of the policy might be greater if it were more fully implemented and coordinated with efforts to improve public acceptance and awareness. 相似文献

Because of difficulties collecting sales taxes on Internet sales, several states have engaged in an effort (the Streamlined Sales Tax Project, SSTP) to simplify their sales tax systems. One hope among SSTP proponents is that a simplified system will result in Internet vendors voluntarily collecting the sales tax. We address two issues:
- ? Will states adopt the extensive reforms proposed by the SSTP?
- ? Will vendors voluntarily collect the sales tax?

The recent decline, indeed perhaps dismantling, of managed care is sometimes treated as both consequence and cause of the political reempowerment of medical providers, whose professional dominance managed care had challenged. Drawing evidence from Round III of the Community Tracking Study of the Center for Studying Health System Change, this article reviews the politics of four "arenas" of managed care regulation--prompt payment, mandated benefits, external appeals, and financial solvency--and concludes that the power of providers is contingent on patterns of coalition and conflict that differ across the discrete arenas. The zero-sum connotations of the "de" and "re" empowerment of providers under managed care fail to capture the subtlety of providers' search for fresh cultural, economic, and political resources in shifting policy contexts. 相似文献
