Is financial aid available to students, including international students?
Yes, Kellogg offers a five-year financial aid package to all admitted doctoral students that includes a stipend, tuition scholarship, health insurance, moving allowance, and a subsidy to purchase a computer.
What academic background is required?
PhD study requires strong quantitative skills to develop theories and manage and analyze data. The PhD Program is especially well suited to students who have previously studied social sciences (such as economics, political science, psychology and sociology), mathematics, natural sciences, or engineering.
Economics-based PhD programs which include Accounting Information & Management, Finance, Financial Economics, Managerial Economics & Strategy, Operations Management, and Marketing (quantitative area) require evidence of solid training in math, econometrics, and statistics within the application. Recommended math courses include calculus, linear algebra, probability and mathematical statistics.
For those applying to Management & Organizations and Marketing (behavioral area), statistics for social scientists is recommended with evidence of quantitative thinking and a good understanding of central concepts of probability and statistics.
How long does it take to complete a PhD degree?
On average, students complete the requirements in 5.5 years. Typically, students complete their coursework in years one and two. Years three through five are spent on research and writing of the dissertation.
If I already have a master's degree, will I be able to complete my PhD degree in a shorter period?
No, while Kellogg admits students with master's degrees, the coursework undertaken in a master's program is not at the PhD level. Master's and PhD coursework requirements are different; therefore, students must satisfy the PhD coursework requirements at Kellogg.
Do you offer a part-time PhD program or a distance-learning/external program?
No, our PhD program is a full-time commitment. You must be on our Evanston campus to attend classes and be an active member of our research community.
