Studies Leading to a Ph.D. Degree
The Ph.D. program is a rigorous extension of M.S. work with the opportunity for the student to broaden and strengthen training. Students applying for the Ph.D. program should have completed an M.S. degree. In addition to training in economics and agricultural economics, the student is expected to be sufficiently grounded in mathematics and statistics. It is the responsibility of the student to address any deficiencies. All 7000-level AGEC courses are listed in Appendix D in the Graduate Student Handbook.
There are five major steps in fulfilling the requirements for the Ph.D. in the Department of Agricultural Economics and Agribusiness: (1) development of the program of study; (2) successful completion of required coursework; (3) successful completion of the qualifying examination in microeconomics or grades of ≥B- in both ECON 7701 and ECON 7702; (4) successful completion of the general examination (written and oral portions); and (5) successful completion of the final examination. At least one academic year of continuous residence (two consecutive semesters) as a full-time graduate student must be earned at LSU after the program of study is submitted and approved by the Graduate School.
In addition, students in the Ph.D. program must maintain continuous registration for a minimum of three semester hours of credit each regular semester (excluding summers) from the completion of the general examination to the end of the semester in which an approved dissertation is submitted to the Graduate School. Students holding assistantships during this time must meet enrollment requirements of the assistantship. Graduate students must be in good academic standing to qualify for examinations.
Program of Study
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.
Students must take ECON 7701 and ECON 7702 during the first year of the Ph.D. program. Students who do not make ≥B- in both courses must pass a written qualifying examination in microeconomics during the summer following their first year of coursework to continue in the Ph.D. program. Students transferring into the program who have taken coursework equivalent to ECON 7701 and ECON 7702 at other universities may take the qualifying examination in lieu of ECON 7701 and ECON 7702 if approved by the student’s committee.
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.
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.
Ph.D. Course Requirements
Ph.D. students are required to complete (1) core courses ECON 7610, ECON 7630, ECON 7631, ECON 7717, ECON 7701, and ECON 7702; (2) AGEC 7123 or ECON 7632 or ECON 7633; (3) ≥18 hours of 7000-level AGEC coursework. Most of the coursework for the fields will count toward the 18-hour AGEC 7000-level requirement. Table 6 in the Graduate Student Handbook shows the general structure of coursework in the Ph.D. program. The number of credit hours required as shown is beyond the B.S. level. Students normally are expected to exceed these minimum requirements. Students are required to complete 12 hours of Economic Theory, 9 hours of Quantitative Methods, 18 hours of Agricultural Economics courses, 6 hours of 7000-level Approved Electives, and 12 hours of Dissertation Research, for a total of 57 hours. The approved electives may be used to develop a specialization or to gain breadth in the Ph.D. program. Students entering the program with deficiencies in their background training may be required to take additional courses.
Preparation of the Dissertation
Ph.D. students, with graduate committee and graduate adviser approval, may elect to prepare the dissertation in either traditional or journal style. Guidelines for preparation of both styles are presented in Guidelines for the Preparation of Theses and Dissertations, available in the Graduate School. Students electing to use the journal style must indicate this choice during the first year of the program.
