Research opportunities are available in the Economics Department, in the greater Columbia community and outside the University. Students begin research as early as in the summer after their first year. The Program for Economic Research (PER) supports many PhD student research initiatives. For more information, see link here. Depending on their areas of interest, PhD students collaborate with Economics faculty and/or faculty in other schools such as the Business School, School of International and Public Affairs and Mailman School of Public Health, among others. The Graduate School of Arts and Sciences supports student research as well. For more information, see link.
