As part of the reforms of their systems for financing and delivering health care, many transition economies, particularly in central and eastern Europe, have adopted national insurance funds that are institutionally separate from ministries of health. Most of these countries have also grappled with the problem of restructuring the delivery system, especially the need to reduce hospital capacity. Although improving the performance of medical care providers through a shift from passive budgeting to explicitly incentive mechanisms is important, why this change in financial relations between the government and providers could not be implemented simply by reforming the role of health ministries is not obvious. This paper presents an explicit rationale for the separation of powers between the regulator (the ministry of health) and the financing body (the insurance fund), based on the inability of a single agency to commit to closing hospitals.

This paper presents a synthesis of innovations in the slicing and dicing of cash flows of a share of a firm's common stock. It begins by discussing PRIMEs and SCOREs, then Unbundled Stock Units (USUs), and finally three proposed hybrid equity options called DIVS, OWLS, and RISKS.
Decomposing a share of stock into components that can be traded separately allows investors to choose between the different investment attributes constituting the underlying share. An investor who desires only cash dividend income may buy only DIVS, and another who values capital appreciation but not current income can purchase only the residual claim.
Derivatives seem to go through a developmental process that is analogous to the biological phenomenon of natural selection and adaptation. The engines that drive this evolutionary process are changing domestic and international market conditions, international tax and regulatory arbitrage, and, of course, the financial innovators who learn from their own mistakes, and from the experience of others. These innovators continually develop new products that represent improvements over the old, if only by their ability to adhere more closely to the guidelines laid down by the regulators. The histories of PRIMEs and SCOREs, of USUs, and, most recently, of DIVS, OWLS and RISKS together provide a nice illustration of this developmental process.  相似文献

We report the results of a novel experiment that addresses two unresolved questions in the judgmental forecasting literature. First, how does combining the estimates of others differ from revising one’s own estimate based on the judgment of another? The experiment found that participants often ignored advice when revising an estimate but averaged estimates when combining. This was true despite receiving identical feedback about the accuracy of past judgments. Second, why do people consistently tend to overweight their own opinions at the expense of profitable advice? We compared two prominent explanations for this, differential access to reasons and egocentric beliefs, and found that neither adequately accounts for the overweighting of the self. Finally, echoing past research, we find that averaging opinions is often advantageous, but that choosing a single judge can perform well in certain predictable situations.  相似文献
