Daniel Trefler (born 1959) is a Canadian economist who is currently the J. Douglas and Ruth Grant Chair in Competitiveness and Prosperity at the Rotman School of Management, University of Toronto. He is among the most influential and frequently cited economists worldwide. Background Born and raised in Toronto, Trefler graduated from the University of Toronto in 1982 with a B.A. in economics and mathematics. He then attended Cambridge University and UCLA, receiving his M.Phil. from the former (1983) and Ph.D. from the latter (1989). Starting that year, he worked at the University of Toronto's Department of Economics. He spent the two years from 1994 to 1996 at the University of Chicago, before deciding to return home permanently to Toronto to serve as a professor at the Rotman School in the University of Toronto. In 2004, he was awarded the prestigious Canada Research Chair. Career Trefler's work has provided academics, policymakers, and business leaders with invaluable observations on economic issues facing Canada and nations worldwide. Some of his most recognized academic contributions include his "case of the missing trade", the impact of exporting on firm productivity, and the relationship between a country's income and the products it exports. His studies have brought deep insights into how international trade can fundamentally alter societal institutions: for example, how changes in the relative power of special interest groups can impact innovation, constitutional arrangements, worker rights, and the distribution of wealth. Currently, he has been studying the impact of artificial intelligence on trade. Trefler is renowned for his ground-breaking contributions to public policy formation in Canada, and he has been given full scope to pursue his many policy initiatives, including in the Ontario Task Force on Competitiveness, Productivity and Economic Progress, as well as in Global Affairs Canada. His research has been instrumental in the design of trade agreements that promote productivity, innovation, and investment while minimizing harmful effects on workers. In recent years, he helped frame the document that launched the Canada-EU trade agreement. In Canada, Trefler is a Senior Research Fellow at the Canadian Institute for Advanced Studies, a research fellow at the C.D. Howe Institute, an advisor to the Institute for Competitiveness and Prosperity, and served as a member of the academic advisory board in the Department of Foreign Affairs and International Trade. Internationally, he is a research fellow at the National Bureau of Economic Research and the Centre for Policy Research.
