Professor Feigenbaum has a Ph.D. in economics from the University of Iowa and a Ph.D. in physics from the University of Chicago. He has worked as an intern and consultant at the Federal Reserve Bank of St. Louis and as an assistant professor at the University of Pittsburgh and now at Utah State University.
His research primarily focuses on life-cycle consumption and saving, general equilibrium calibration and simulation, computational methods, and quantitative finance. He has played a key role in a literature that builds life-cycle models that are capable of reproducing the most important features of the life-cycle consumption/saving experience in the U.S. In particular, he has advanced our understanding of the importance of mortality risk, idiosyncratic earnings risk, borrowing constraints, and the labor-leisure choice in explaining life-cycle consumption data. He has also studied the application of physics models in financial contexts.
