The Guest Book is expired.
Phillip David Cagan, author and scholar in the field of macroeconomics, Professor Emeritus at Columbia University, and beloved father, passed away peacefully on June 15th, aged 85, in Palo Alto, California. He made significant contributions to the field of economic science, most notably to monetary economics and the study of inflation.
Prof. Cagan published over 100 books, journals, reviews, reports and pamphlets. His Ph.D. dissertation, "The Monetary Dynamics of Hyperinflation," published as the leading chapter in the volume "Studies in the Quantity Theory of Money" (University of Chicago Press, 1956), was immediately acclaimed as a classic. The model of money demand proposed and fit to historical data in this study, known as the "Cagan model," remains the definitive study of the problem of hyperinflation and has continued to be a staple of reading lists of courses in monetary economics for more than 50 years. Cagan's dissertation supervisor, Milton Friedman, wrote of his thesis, "There are not many doctoral dissertations that had so wide an impact or have come to occupy so lasting a place in economic literature."
Cagan's most important later works were the books "Determinants and Effects of Changes in the Stock of Money, 1875-1960" (Columbia University Press,1965) and "Persistent Inflation: Historical and Policy Essays" (Columbia University Press, 1979).
Phillip Cagan was born on April 30th, 1927 and grew up in Beverly Hills, California. He joined the Navy at age 17. He attended UCLA for two years, where he played on the tennis team. He received his M.A. followed by a Ph.D. in Economics in 1954 from the University of Chicago. He then worked for the National Bureau of Economic Research (NBER) in New York for two years. Subsequently, he taught at the University of Chicago for three years and at Brown University for seven years. He was hired by Columbia University in 1966, where he taught economics for nearly thirty years, and held the Chair of the Department of Economics for three years.
In 1969, Prof. Cagan took a 15 month sabbatical from Columbia to work for the Council of Economic Advisors (CEA) under the Nixon administration. During his time at Columbia, Prof. Cagan was also associated with the American Enterprise Institute (AEI) in Washington, D.C., for which he wrote extensively on public policy issues. In 1975 Prof. Cagan was elected a Fellow of the Econometric Society. He continued to play tennis, a lifelong passion, until he was 80.
