Julia K. Thomas is a Professor of Economics at the Ohio State University and a Faculty Research Fellow in the Economic Fluctuations and Growth group at the National Bureau of Economic Research. She has held previous positions at the Federal Reserve Bank of Philadelphia, the University of Minnesota and Carnegie Mellon University. She served as an Associate Editor for the Journal of Monetary Economics over 2009-2011, and is currently an Associate Editor for the Review of Economic Dynamics. She was awarded the Alfred P. Sloan Research Fellowship in 2004 and received research support from a National Science Foundation grants over 2003-06, 2011-14, and 2014-17.
Professor Thomas’ research focuses on how discrete and occasional actions among heterogeneous economic agents affect the size and shape of aggregate fluctuations, with an emphasis on the business cycle frequencies. She has examined the aggregate business cycle in dynamic stochastic general equilibrium (DSGE) models with lumpy establishment-level investment arising from nonconvex capital adjustment costs, and in DSGE models where explicit microeconomic frictions prompt firms to accumulate inventories. In more recent work, she has been exploring aggregate dynamics following changes in monetary policy in models with discrete and occasional portfolio adjustments among households, and she has begun developing DSGE models where collateralized borrowing limits interact with rich firm-level heterogeneity to study the implications of financial shocks for aggregate fluctuations. Professor Thomas has published papers in a number of journals, including the American Economic Review, Econometrica, the Journal of Monetary Economics, and the Journal of Political Economy.
