One of the most fundamental issues in health care delivery is who should decide which items of medical care are not worth their cost. This book is a fresh and comprehensive exploration of how health care rationing decisions are made. Unlike prior works, its focus is not on the specific criteria for rationing, like age or quality of life. Instead, the author provides comparative analysis of alternative social mechanisms for making medical spending decisions: (1) consumers paying for their medical treatment out of pocket; (2) payers, government officials, or other centralized authorities setting limits on what doctors can do and what insurance will pay for; and (3) physicians motivated to make these decisions at the bedside level. His analysis of each of these mechanisms reveals that none is uniformly superior, and each is better suited for certain decisions that others. Therefore, a mix of all three is inevitable.The author develops his analysis along three dimensions: political economics, ethics, and law. The political economic dimension discusses the practical and theoretical aspects of each method for making spending decisions, synthesizing empirical studies of the situations in which each mechanism has been tested. The ethical dimension is based on several strands of philosophical theory, principally classic liberalism, social contract theory, and communitarianism, as well as conceptual analysis of terms such as autonomy and coercion. The legal dimension addresses recent developments in legal doctrine such as informed consent, insurance coverage disputes, and the emerging direction of federal regulation. Hall concludes that physician rationing at the bedside is far more promising than medical ethicists and the medical profession have traditionally allowed. The best way to allocate authority for making medical spending decisions in both public and private systems, he believes, is the informed purchase of different types of health insurance in a managed competition framework.

The tradition of tax-exempt status for nonprofit "charitable" organizations is well established, and few would argue with the principle. But the tax-exempt sector of the economy is vast and rapidly growing, resulting in the loss of billions of dollars of tax revenue. At the same time, we have no consensus on what purpose the charitable tax exemption serves, let alone agreement on what constitutes a charity. In this important addition to the theory of tax law, Colombo and Hall develop an original "donative" theory that links the charitable tax exemption to the ability of an organization to derive donative support from the community. Their theory not only makes intuitive sense but also receives support from economic, political, and moral theory. Its implications would rationalize the charitable tax exemption, comport with legal precedent, and simplify the administration of the law. The Charitable Tax Exemption is a major contribution to the theory of tax law and should be essential reading for a wide range of lawyers dealing with taxes. It will also be enlightening for anyone involved in the operation of a nonprofit organization

The Health Care Safety Net in a Post-Reform World examines how national health care reform will impact safety net programs that serve low-income and uninsured patients. The “safety net” refers to the collection of hospitals, clinics, and doctors who treat disadvantaged people, including those without insurance, regardless of their ability to pay. Despite comprehensive national health care reform, over twenty million people will remain uninsured. And many of those who obtain insurance from reform will continue to face shortages of providers in their communities willing or able to serve them. As the demand for care grows with expanded insurance, so will the pressure on an overstretched safety net.This book, with contributions from leading health care scholars, is the first comprehensive assessment of the safety net in over a decade. Rather than view health insurance and the health care safety net as alternatives to each other, it examines their potential to be complementary aspects of a broader effort to achieve equity and quality in health care access. It also considers whether the safety net can be improved and strengthened to a level that can provide truly universal access, both through expanded insurance and the creation of a well-integrated and reasonably supported network of direct health care access for the uninsured.Seeing safety net institutions as key components of post-health care reform in the United States-as opposed to stop-gap measures or as part of the problem-is a bold idea. And as presented in this volume, it is an idea whose time has come.

Medieval kings and kingship, and the rituals that define them, continue to captivate both scholars and the wider public. This interdisciplinary volume offers a Europe-wide perspective on early medieval kingship, with a particular focus on Scotland. What types of royal sites existed in the early medieval period in Scotland, and how did they vary regionally? Can we trace these sites in placenames? What rituals and other activities were associated with these sites, and what purposes did they serve? These and other questions are explored in the papers gathered together in this interdisciplinary volume. Drawing together experts in archaeology, history, placenames, folklore, poetry, and art history, the volume unpacks the story of early medieval kingship in Scotland against a European backdrop and across multiple scales, from multi-site regions and the mobile exercise of kingship, to single-site landscapes, analysis of significant objects, and the memorialisation of stories through tradition. Framed by recent archaeological excavations in Scotland, Wales, Ireland, England, and Scandinavia, this book presents a rich and innovative approach to the study of kingship in the early medieval period.
