A challenge facing society today is how to develop a meaningful strategy for integrated hazardous waste management. Meeting this challenge was the principal motivation for the conference on "Risk Assessment and Risk Management Strategies for Hazardous Waste Storage and Disposal Prob lems," held at the Wharton School of the University of Pennsylvania on May 18-19, 1988. The conference brought together representatives from the major interested parties - environmentalists, government, insurance, law, manufacturing, and the university community - who have been con cerned with the waste management process. The conference was the third cosponsored by the Wharton Center for Risk and Decision Processes addressing the knotty problem of hazardous waste. The first, held at the International Institute for Applied Systems Analysis in 1985, examined the transportation, storage, and disposal of hazardous materials. It suggested steps that industry, insurers, and gov ernment agencies could take to improve the safety and efficiency with which hazardous materials are produced and controlled in industrialized societies. Specifically, it focused on the risk-management tools of insurance, com pensation, and regulation. xv xvi PREFACE The second conference, held at the Wharton School, University of Penn sylvania in 1986, concentrated on the role of insurance and compensation in environmental pollution problems. It characterized a set of problems related to the environmental pollution liability insurance crisis as presented by key interested parties and proposed a set of research needs for providing a sound basis for constructing socially appropriate measures to deal with the problem."

When people make judgments and choices, especially when faced with uncertainty, they behave in a manner that seems complex and irrational. Cognitive psychologists have identified and organized these patterns of behavior into a descriptively accurate model of human judgments and choices called behavioral decision theory. Incorporating this theory's insights in public policy analysis will enhance our ability to design better policies and enable us to understand the limits of effective regulation.

Behavioral decision theory draws on experimental research in cognitive psychology to provide a descriptively accurate model of human behavior. It shows that people systematically violate the normative assumptions of economic rationality by miscalculating probabilities and making choices based on one-economic criteria. Behavioral decision theory's ability to capture the complexity of human judgments and choices makes it a useful foundation for improving public policy analysis, design, and implementation. Originally published in 2001, this volume showcases the research of leading scholars who are working on applications of behavioral decision theory in diverse policy settings. It is designed to give policy analysts and practitioners who are non-psychologists a clearer understanding of the complexities of human judgment and choice, and suggest how to integrate behavioral decision theoretic insights into the policy sciences. This interdisciplinary volume should be insightful and useful wherever people's judgments and choices matter for policy formulation, acceptance, and effectiveness.
