Leonard Jay Mirman (March 19, 1940 – September 6, 2017) was an American mathematician and economist.
He was the Paul G. McIntire Professor of Economics at the University of Virginia.
A native of New York City, Mirman earned a bachelor's (1963) and a master's degree (1965) in mathematics from Brooklyn College and New York University, respectively.
While still a graduate student, Mirman started a paper with William A. Brock, who was then an assistant professor in the department, that augmented the Ramsey–Cass–Koopmans model with stochastic technology progress.
[1] As business cycle fluctuations arise naturally in this setup, the Brock–Mirman model became the foundation of real business cycle theory, which is at the heart of modern macroeconomics and growth theory.
