Charles Irving Plosser (born September 19, 1948 in Birmingham, Alabama) is the president of the Federal Reserve Bank of Philadelphia. An academic macroeconomist, he is well known for his work on real business cycles, a term which he and John B. Long, Jr. coined. Specifically, he wrote along with Charles Nelson in 1982 an influential work entitled "Trends and Random Walks in Macroeconomic Time Series" in which they dealt with the hypothesis of permanent shocks affecting the aggregate product (GDP).
Before joining the Philadelphia Fed, Plosser was for 12 years the Dean of the William E. Simon Graduate School of Business Administration at the University of Rochester and served concurrently as the school's John M. Olin Distinguished Professor of Economics and Public Policy.
He earned Ph.D. and M.B.A. degrees from the University of Chicago in 1976 and 1972, respectively, and a bachelor of engineering degree from Vanderbilt University in 1970. He is also a graduate of Indian Springs School in Indian Springs, Alabama.
