Born in Joplin, Missouri (1944), Roger W. Garrison earned a Bachelor of Science in Electrical Engineering (Missouri School of Mines, 1967), after which he served as a commissioned officer in the United States Air Force (1967-1971). On obtaining his Master of Arts in Economics (University of Missouri at Kansas City, 1974), he spent two years at the Federal Reserve Bank of Kansas City. He then resumed his study of economics at the University of Virginia, where he completed his doctorate degree (1981). 

Professor Garrison has been a member of the faculty at Auburn University since 1978. He teaches macroeconomics at both the principles level and the advanced level and is widely known for his Austrian-oriented  writings on capital, money, business cycles, and deficit finance.

A member of the Society for the Development of Austrian Economics, Professor Garrison also maintains affiliations with the Foundation for Economic Education of Irvington-on-Hudson, New York and with the Ludwig von Mises Institute of Auburn, Alabama.

Professor Garrison's work appears in such journals as the American Economic Review, Economic Inquiry, Journal of Macroeconomics, Journal of Money Credit and Banking, History of Political Economy, South African Journal of Economics, Cato Journal, and Review of Austrian Economics. He co-authored, with Israel M. Kirzner, the entry on Nobelist F. A. Hayek for the New Palgrave Dictionary of Economics (1987). 

Professor Garrison was featured as a representative of the Austrian School in an extended interview that appears in Brian Snowdon et al., A Modern Guide to Macroeconomics: An Introduction to Competing Schools of Thought (Edward Elgar, 1994). He delivered the Ludwig Lachmann Memorial Lecture at the University of the Witwatersrand, Johannasburg, South Africa, in 1997. 

Most recently, he published a book-length treatment of capital-based macroeconomics in Time and Money: the Macroeconomics of Capital Structure (London: Routledge, 2001).  Time and Money was a 2001 winner of the Smith Prize, awarded annually by the Smith Center for Private Enterprise Studies for best book in Austrian economics.

Professor Garrison, his wife Karen, and son Jimmy make their  home in Auburn, Alabama. He is an active member in the East Alabama Old Car Club and enjoys maintaining and showing his 1940 Buick.
