7.0. Doctor of Philosophy Degree Program

The doctoral program in Agricultural and Applied Economics is designed to develop a broad based competence in economic theory and in techniques of quantitative analysis. Dissertation research of students in our department usually addresses applied problems using contemporary economic theory and analytical methods. Students completing our program have demonstrated a high degree of success in academics, business, and government.

Two options are offered for the Doctor of Philosophy in the Agricultural and Applied Economics program. The first option does not require a minor. The second option includes a minor in Family Financial Planning—a joint Ph.D. program between the Department of Agricultural and Applied Economics and the College of Human Sciences. Completion of the Doctoral program in Agricultural and Applied Economics with a minor in Family Financial Planning qualifies graduates to take an exam administered by the Certified Financial Planning Board of Standards to become Certified Financial Planners.

7.1. Prerequisites

Most students will have completed the requirements for an M.S. degree or its equivalent before admission to the doctoral program. If the Master's degree does not meet the prerequisite requirements for entering our Master of Science program (see Section 5.1) then those requirements must be met in order to enter the Ph.D. program.

7.2. Credit Hour Requirements

The doctoral program requires a minimum of 60 credit hours of course work beyond the baccalaureate degree and at least 12 credit hours of dissertation research (AAEC 8000).

7.3. Transfer of Credit

Transfer of graduate credit from other academic institutions may be allowed. The request for transfer must be initiated by the student and supported by the student's committee chair. Transfer decisions are made by the department Graduate Advisor and must be approved by the Graduate School. Information required in support of transfer requests includes academic transcripts and course catalogue descriptions of each course proposed for transfer. Course syllabi may also be requested to support transfer decisions.

7.4. Substitution for Core Courses

Substitutions for core courses are allowed only under unusual circumstances. Requests for substitutions for core courses must be initiated by the student and his or her committee chair, to the department Graduate Advisor. Final decisions on substitutions for core courses taught outside our department are made by the department Graduate Advisor. Decisions on core courses taught in the department are made by the current instructor of the core course being replaced.

7.5. Ph.D. Comprehensive Examination

The purpose of the Ph.D. comprehensive examination is to test the student's ability to integrate knowledge from various subject matter areas and apply appropriate concepts and tools to issues and problems relevant to the discipline. The comprehensive exam is administered by a departmental committee twice each year (usually in May and August) and is normally taken at the end of the first full year of coursework. The exam has two parts which are taken separately. Part 1 of the exam focuses econometric methods and Part 2 covers microeconomic theory. Students have two opportunities to pass both parts of the exam. If both parts of the exam are passed on the first attempt then the student has successfully completed this degree requirement. If one or both parts of the exam are failed on the first attempt (usually in May), the student must retake the failed part(s) at the next offering (in the following August). A second failure of either part of the comprehensive exam will result in dismissal from the student's Ph.D. program.

7.6. Qualifying Examination and Admission to Candidacy

Graduate school rules require that all doctoral students successfully complete a Qualifying Examination for admission to candidacy for the doctor's degree. In the Department of Agricultural and Applied Economics the Dissertation Proposal Defense serves as the Qualifying Exam. Students are allowed two attempts to satisfactorily complete this examination. Failure to satisfactorily complete the examination on a second attempt will result in dismissal from the Ph.D. program. Further information on the Dissertation Proposal and Proposal Defense is provided in Section 9.0 of this Handbook.

7.7. Final Examination

All doctoral candidates are required to pass a public final oral examination which is usually over the general field of the dissertation. Candidates should consult the Graduate School for details regarding scheduling of the final examination. After the final examination, the major professor will send a written notification of the results to the Graduate School.

Listed below are the course requirements for the Ph.D. program options. Courses listed specifically by number are core courses. Note that the option II course requirements have been revised in consultation with the Department of Personal Financial Planning and are pending approval of the Agricultural and Applied Economics faculty.
