Peter Kuhn is a labor economist whose research has studied displaced workers, labor unions, gender differentials in labor markets, and search and matching. His research has been funded by the NSF, NIH, and Ford Foundation, among others. He is a Research Associate of the National Bureau of Economic Research (NBER), the Institute for the Study of Labor (IZA), and the Center for Economic Studies (CES) and was recently voted a Fellow of the Society of Labor Economists. He currently serves as Editor in Chief of the Journal of Labor Economics and sits on the editorial boards of the Industrial and Labor Relations Review and Labour Economics.

Professor Kuhn pioneered the study of online matching between workers and firms with a series of articles published in the early 2000s, including "Internet Job Search and Unemployment Durations", in the American Economic Review (2004). He remains active in this area, especially in the use of internal data from job boards to study a range of economic issues, including the effects of job ad content on application behavior and on the composition of successful job candidates, for example in “What Happens When Employers Can No Longer Discriminate in Job Ads?", also in the AER (2023).
