It is increasingly common for analysts to seek out the opinions of individuals and organizations using attitudinal scales such as degree of satisfaction or importance attached to an issue. Examples include levels of obesity, seriousness of a health condition, attitudes towards service levels, opinions on products, voting intentions, and the degree of clarity of contracts. Ordered choice models provide a relevant methodology for capturing the sources of influence that explain the choice made amongst a set of ordered alternatives. The methods have evolved to a level of sophistication that can allow for heterogeneity in the threshold parameters, in the explanatory variables (through random parameters), and in the decomposition of the residual variance. This book brings together contributions in ordered choice modeling from a number of disciplines, synthesizing developments over the last fifty years, and suggests useful extensions to account for the wide range of sources of influence on choice.

Connecting Research and Practice for Educational Improvement presents powerful arguments and richly illustrated cases for how more collaborative relationships between researchers and educators can yield more relevant research that impacts practice. This book can be useful for anyone teaching or learning about research–practice partnerships, in both school and out-of-school settings. The chapters highlight the different dispositions and skills needed to cultivate ethical relationships and promote equity through partnerships and provide rich frameworks for guiding future work.
Almost 5 years ago we began working together on research for the U.S. Environmental Protec tion Agency (EPA) to measure the benefits of water quality regulations. EPA had awarded a contract to Research Triangle Inst~ute (RTIl in response to a proposal that Bill wrote on measuring these benefits. After meeting with the EPA project officer, Dr Ann Fisher, the basic outlines of what would become this research were framed. Upon the suggestion of Bob Anderson, then chief of the Benefits Branch at EPA, we selected the Monongahela River as the focal point of a case study that would compare alternative benefit measurement approaches. Exactly how this case study would be done remained vague, but Ann urged that there be a survey and that nonuse benefits be included in the question naire design. Of course, Bill agreed. At the same time, Kerry was independently working on a review article that tied together some of the loose threads in the option value literature. He had also been thinking about how to measure option value, as well as working on ways to generalize the travel cost approach for estimating benefits of site attributes. Glenn Morris at RTI suggested that Bill have lunch with him and Kerry and that they could talk about Bill's research to see if there were any mutual interest. Over the lunch and Bill's ever present dessert in a Chapel Hill restaurant, we found out just how much we have in common.
This second edition of Measuring Nonuse Damages Using Conjoint Valuation is essentially a reprint of a 1992 monograph that has been in steady demand since its original appearance. The RTI Press edition, which is intended to meet continued inquiries and requests for the monograph, contains a Foreword and a Preface to the second edition that put the original work into historical perspective. These studies of ways to value stated preferences, as applied then to the Exxon Valdez oil spill, continue to be a timely and still-rigorous examination of such methods; even with the passage of time and statistical advances from the past two decades, the conclusions and insights as to whether and how these techniques might still be employed in valuing use or nonuse losses from similar events remain valid.
The papers contained in the first part of the book are particularly valuable as a primer for researchers interested in economic discrimination. On this basis alone this book is recommended for researchers seeking an overview of current techniques for assessing economic discrimination. . . The final section nicely highlights both the importance in understanding the interaction of policy and economic discrimination, and the difficulties in isolating policy effects. Education Economics Editor Rodgers has compiled a very useful book that summarizes the current state of the literature on economic discrimination. . . This reviewer learned something new and interesting in every chapter and particularly appreciated the clear survey of the age discrimination literature. . . This book will be of value to academics and to those in the legal arena. Highly recommended. J.P. Jacobsen, Choice Discrimination s dynamic nature means that no single theory, method, data or study should be relied upon to assess its magnitude, causes, or remedies. Despite some gains in our understanding, these remain active areas of debate among researchers, practitioners and policymakers. The specially commissioned papers in this volume, all by distinguished contributors, present the full range of issues related to this complex and challenging problem. Part 1 explores innovations in methods and data collection that help to provide richer descriptions of inequality. Part 2 reviews empirical evidence on discrimination that people with disabilities, older workers and gay, lesbian and bisexual individuals face. Although discrimination among these groups is not new, this Handbook shows that economists are beginning to more fully document their experiences. Part 3 presents a balanced discussion of anti-discrimination policies and the impact of affirmative action. The methods and data chapters are particularly designed to encourage researchers to utilize the new approaches and develop new data sources. Accessible and comprehensive, the Handbook is the seminal reference on the economics of discrimination for academic and professional economists, graduate students, advanced undergraduates, practitioners, policymakers, and funders of social science research.
