Professor Case's research was in the areas of real estate, housing, and public finance. He authored or coauthored five books, including Principles of Economics, Economics and Tax Policy, and Property Taxation: The Need for Reform, and published numerous articles in professional journals, focused on real estate markets and prices.

Chip, as he was known to his many friends and colleagues, contributed to this textbook throughout its many editions. In his honor and with respect for his substantial contributions to the text and the discipline of economics, his co-authors plan to keep his name on the text for all future editions.

Ray C. Fair is Professor of Economics at Yale University. He is a member of the Cowles Foundation at Yale and a Fellow of the Econometric Society. He received a BA in Economics from Fresno State College in 1964 and a PhD in Economics from MIT in 1968. He taught at Princeton University from 1968 to 1974. Professor Fair has taught introductory and intermediate macroeconomics at Yale since 1974. He has also taught graduate courses in macroeconomic theory and macroeconometrics.

Professor Fair's research has primarily been in the areas of macroeconomics and econometrics, with particular emphasis on macroeconometric model building. He has also done work in the areas of finance, voting behavior, and aging in sports. His publications include Specification, Estimation, and Analysis of Macroeconometric Models (Harvard Press, 1984); Testing Macroeconometric Models (Harvard Press, 1994); Estimating How the Macroeconomy Works (Harvard Press, 2004), and Predicting Presidential Elections and Other Things (Stanford University Press, 2012).

Professor Fair's US and multicountry models are available for use at fairmodel.econ.yale.edu, free of charge. Many teachers have found that having students work with the US model on the internet is a useful complement to an introductory macroeconomics course.
