David Dorn

David Dorn studied at the University of St. Gallen, where he earned M.Sc.s in economics and international management as well as a Ph.D. in economics in 2004 and 2009 respectively, and performed exchange terms at the ESADE Business School and the University of North Carolina at Chapel Hill. After his Ph.D., Dorn became an assistant professor at the CEMFI in Madrid, where he was promoted to associate professor in 2013. In 2014, he accepted a position as Professor of International Trade and Labor Markets at the University of Zurich, where he was promoted to the UBS Chair of Globalization and Labor Markets in 2019. Dorn has also held positions as visiting scholar or professor at the University of Chicago, Massachusetts Institute of Technology, Boston University and Harvard University. He maintains affiliations with the Centre for Economic Policy Research, CESifo, and the IZA Institute of Labor Economics. In terms of professional service, Dorn performs or has performed editorial duties at the Journal of the European Economic Association and the Review of Economic Studies.

Dorn, David Autor and Gordon Hanson find that rising imports from China caused higher unemployment, lower labour force participation and reduced wages in local U.S. labour markets that house manufacturing industries that compete with those imports, explaining up to a quarter of the decline in U.S. manufacturing employment. At the individual level, persons who worked in 1991 in manufacturing industries in which imports from China grew strongly experienced lower aggregate earnings and change firms and industries more often, with churning particularly concentrated among those who had low initial wages, tenure or labour force attachment, while high-wage workers are much better able to adjust in case they are forced out of their jobs. More generally, job losses in the U.S. due to rising competition from Chinese imports over 1999-2011 were estimated by Dorn, Autor, Hanson, Daron Acemoglu and Brendan Price to amount to 2–2.4 million, with offsetting employment gains in other industries yet to materialize. Finally, while the impacts of trade with China grow in the 2000s as imports accelerate, labour markets in the U.S. with industries less exposed to Chinese trade but characterized by a high routine task content still experienced occupational polarization, first due to the automation of production activities in manufacturing and then due to the computerisation of information-processing tasks in non-manufacturing sectors. More recently, Dorn, Autor, Lawrence F. Katz, Christina Patterson and John van Reenen have connected the fall of the labour share in the U.S. to the rise of "superstar firms" by arguing that globalization and/or technological changes might advantage the most productive firms in each industry and that productivity is related to a low share of labour in firms' value added, resulting in industries becoming increasingly dominated by such "superstar firms" as well as in a falling aggregate labour share; they find empirical support for predictions based on this hypothesis.

David Dorn (born 1979) is a Swiss economist and currently the UBS Professor of Globalization and Labor Markets at the University of Zurich. His research focuses on the interplay between globalization and labour markets. In 2014, his research was awarded the Excellence Award in Global Economic Affairs by the Kiel Institute for the World Economy.
