Within the first semester of the Ph.D. program, a student must submit a program of study to the Graduate School for approval. Students are expected to develop a coursework proposal during their first semester and have it approved by their graduate committee once the committee has been appointed.

General Examination

The written Departmental Ph.D. General Examination consists of questions administered by the Departmental General Examination Committee upon completion of core coursework (after four semesters for students starting in the fall semester; after five for students starting in the spring semester).  

Students will have two opportunities to pass this exam. Failure to pass the written portion of the General Examination on the second attempt will terminate the student's program. The general examination will consist of questions from core economic areas such as production, consumption, marketing, trade, development, resource or environmental economics and research methods.  

The written examination will be offered in June of each year.  For students who fail, they will be allowed to re-take the written general examination once in August of the same year. Students who have not passed the written general examination before the fall semester starts (August of that same year) will not be able to continue in the Ph.D. program.

An oral examination is given after successfully completing the written exam.  The oral examination generally covers the student’s dissertation proposal, with questions dealing with economic theory and methods pertaining to the dissertation research.  

Final Examination

The Final Examination may be scheduled after General Examination requirements are satisfied and one academic year (two consecutive semesters) have elapsed since passing the General Examination. The Final Examination, an oral test administered by the student's graduate committee, members from minor departments, and the member appointed by Graduate School, focuses on (but is not confined exclusively to) contents of the dissertation.
