John Barkley Rosser Jr. (April 12, 1948 - January 10, 2023) was a mathematical economist and Professor of Economics at James Madison University in Harrisonburg, Virginia since 1988. He was known for work in nonlinear economic dynamics,[1] including applications in economics of catastrophe theory,[2] chaos theory,[3] and complexity theory[4][5][6] (complex dynamics, complexity economics). With Marina V. Rosser he invented the concept of the "new traditional economy".[7] He introduced into economic discourse the concepts of chaotic bubbles,[8] chaotic hysteresis (op. cit., p. 326), and econochemistry.[9] He also invented the concepts of the megacorpstate[10] and hypercyclic morphogenesis.[11] He was the first to provide a mathematical model of the period of financial distress in a speculative bubble.[12] With Marina V. Rosser and Ehsan Ahmed, he was the first to argue for a two-way positive link between income inequality (economic inequality) and the size of an underground economy in a nation.[13] Rosser's equation has been used to forecast ratios of future Social Security benefits to current ones in real terms.[14]
