Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.

Environmental and Natural Resource Economics is the best-selling text for natural resource economics and environmental economics courses, offering a policy-oriented approach and introducing economic theory and empirical work from the field. Students will leave the course with a global perspective of both environmental and natural resource economics and how they interact. Complemented by a number of case studies showing how underlying economic principles provided the foundation for specific environmental and resource policies, this key text highlights what can be learned from the actual experience. This new, 11th edition includes updated data, a number of new studies and brings a more international focus to the subject. Key features include: Extensive coverage of the major issues including climate change, air and water pollution, sustainable development, and environmental justice. Dedicated chapters on a full range of resources including water, land, forests, fisheries, and recyclables. Introductions to the theory and method of environmental economics including externalities, benefit-cost analysis, valuation methods, and ecosystem goods and services. Boxed ‘Examples’ and ‘Debates’ throughout the text which highlight global examples and major talking points. The text is fully supported with end-of-chapter summaries, discussion questions, and self-test exercises in the book and multiple-choice questions, simulations, references, slides, and an instructor’s manual on the Companion Website.

World Development Report 1994 examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services - especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance.

The federal government is running huge budget deficits, spending too much, and heading toward a financial crisis. Federal spending soared under President George W. Bush, and the costs of programs for the elderly are set to balloon in coming years. Hurricane Katrina has made the federal budget situation even more desperate. In Downsizing the Federal Government Cato Institute budget expert Chris Edwards provides policymakers with solutions to the growing federal budget mess. Edwards identifies more than 100 federal programs that should be terminated, transferred to the states, or privatized in order to balance the budget and save hundreds of billions of dollars. Edwards proposes a balanced reform package of cuts to entitlements, domestic programs, and excess defense spending. He argues that these cuts would not only eliminate the deficit, but also strengthen the economy, enlarge personal freedom, and leave a positive fiscal legacy for the next generation. Downsizing the Federal Government discusses the systematic causes of wasteful spending, and it overflows with examples of federal programs that are obsolete and mismanaged. The book examines the budget process and shows how policymakers act contrary to the interests of average Americans by favoring special interests.
