Ph.D. Agricultural Economics

Students choosing this field area will be uniquely qualified to teach agribusiness and conduct research in academic, government and consulting careers. This program provides a solid foundation of economic theory and application. To gain further expertise and refine their skillset, students pursuing the the agribusiness field area can choose to emphasize in one of four areas:

1. Finance
2. Marketing
3. Strategic Management
4. Supply Chain Management

Students choosing this field area will be uniquely qualified to teach agricultural economics and conduct information economics and food market research. This field area allows students to gain expertise related to market and demand analysis, product valuation, use of directed acyclic graphs in economic analysis, commodity futures and options, information acquisition, price dispersion, industrial organization, and auctions

Students choosing this field area will be uniquely qualified to teach agricultural economics and conduct applied economic research to evaluate the the use, transfer and allocation of natural resources to help inform environmental policy and natural resource management strategies. Students will gain expertise applying economic tools and theories to advance the health and sustainability of our natural world.

ECMT 660: Mathematical Economics I
This course covers use of selected types of mathematical tools in economic theory (e.g., matrix algebra and multivariate calculus).

The topics covered in ECMT 660 are:
It is important that students have good skills in calculus and optimization. It would be valuable to entering students if they reviewed carefully Chapter 2 (the brief math review) in Walter Nicholson, Microeconomic Theory, 7th edition, 1998. Also, students should have a good understanding of the following topics from Alpha Chiang, Fundamental Methods of Mathematical Economics, 3rd (latest) edition, McGraw-Hill, 1984.

Online Calculus Course
An online calculus course is available which may assist you in your preparation for Masters-level course work. This web site provides a clear, helpful interactive tool for learning calculus. This site is a good way to practice the subject.

Supply and demand, consumer optimization, theory of the firm (cost minimization and profit maximization), analysis of different market structures (pure competition, monopoly, monopolistic competition, and oligopoly) will be covered. General competitive equilibrium will be introduced.

Topics covered in ECON 607 include:

All students pursuing a Ph.D. in agricultural economics are required to pass a comprehensive qualifier exam. The qualifier is administered twice a year on the Monday before classes begin for the first Summer term and on August 1 (if August 1 falls on a weekend the exam will be held the first weekday prior to August 1). Traditional Ph.D. students are required to take the qualifier in May of their first year. Straight-through Ph.D. students are required to take the qualifier in May of their second year.

• This exam must be completed by December of your third year.
• If you opted for the paper, you must present it during the oral prelim exam. The paper should be submitted to your Graduate Advisory Committee at least two weeks before the oral exam. exam.
• If you choose the written preliminary examination, you must pass it before taking the oral prelim. At the oral prelim, you will also present a draft of your dissertation proposal.

Additional Information:

• If you are not prepared for the oral prelim exam by December, you must submit a petition   to the Departmental Graduate Advisory Committee (GAC) to request more time.  The Departmental Graduate Office can help with this petition.  If not approved, the oral prelim will be recorded as a fail.
• The oral prelim exam is not limited to the paper or dissertation proposal; your committee may ask about your research plans for the dissertation, mastery of subject matter within your field, and knowledge of the literature in your field.
• Students must pass both the written preliminary (or paper) and oral exam to pass the Preliminary Examination. A failure in either of these examinations constitutes a failure of the Preliminary Examination. Upon unanimous approval of the student’s Advisory Committee and the approval of the Office of Graduate Studies, a student who has failed either part of the Preliminary Examination may be given one re-examination, when adequate time has been given to permit the student to address the inadequacies emerging from the first examination. It is expected that preliminary examination will be concluded before the end of the spring semester of the third year.
• A failure on the second attempt in either the written or the oral examination constitutes a failure, and the student will not have a third chance to take the Preliminary Examination.
• The oral prelim typically includes a departmental seminar where you present your paper or preliminary dissertation proposal draft.
• Finalize and submit your dissertation proposal for signatures before the end of the spring semester in your third year.

Important Note:

• To learn more about the preliminary examination process and its details, please refer to the Departmental Graduate Handbook available at this link: Departmental Graduate Handbook.
• If you decide to pursue the paper option or if you have any questions or need guidance regarding the preliminary examination, please reach out to the Departmental Graduate Office. Good luck with your academic journey!
