The Economics Department at Princeton University is pleased to announce that the Princeton University Board of Trustees has approved the promotion Ezra Oberfield to the role of associate professor with tenure.

Oberfield’s research interests lie in the areas of macroeconomics, firm dynamics, and growth. In March, two of Oberfield’s most recent works were published by the journal Econometrica.

In “Learning from Coworkers“—joint work with his Princeton colleagues Gregor Jarosch and Esteban Rossi‐Hansberg—Oberfield develops a methodology to estimate knowledge flows among coworkers. The authors show that between 4% and 9% of total worker compensation is in the form of learning. In “Micro Data and Macro Technology,” Oberfield and co-author Devesh Raval develop a framework to estimate the aggregate capital‐labor elasticity of substitution for the manufacturing sector by aggregating the actions of individual plants.

You can learn more about Oberfield’s research on his personal website.

Before coming to Princeton, Oberfield was an economist in the Economic Research Department at the Federal Reserve Bank of Chicago. He is a faculty research fellow at the National Bureau of Economic Research and a CESifo research network affiliate. Oberfield received a bachelor’s degree in mathematics and economics from Yale University and a Ph.D. in economics from the University of Chicago.

The Economics Department congratulates Professor Oberfield on this extraordinary accomplishment.
