Current Research Areas

Healthy, sustainable + fair supply Chains

Many people care about the impacts their food purchases have on their health, the environment and other people. I consider who is participating in these supply chains and the individual characteristics and incentives driving their decisions,  as well as whether these supply chains are truly meeting their stated goals.

Market power in the aG supply chain

As companies grow in size or market share, they may be able to exercise market power (the ability to set a higher selling price or a lower buying price than the competitive price). I consider the role of market power in the agricultural supply chain in the context of farm organizations, patent licensing and health policy.

Orgs + networks in the ag supply chain

Along with interacting in markets, farmers and food system stakeholders interact within and outside markets in farm organizations, cooperatives and social networks. I examine food system stakeholders' behavior in these settings and how these interactions connect to actions and outcomes in markets.

It is a lecture-based course, with in-class activities and additional opportunities for class participation using online tools. This course is open to any undergraduates except those who've taken AEDECON 2001H or ECON 2001 and serves as a Social Sciences GE course (Human, Natural, and Economic Resources category). It is also a required course for the Agricultural and Applied Economics and EEDS majors.

We analyze real cost-benefit analyses, read economic papers, and discuss timely issues (e.g., marijuana legalization, the opioid crisis, pollinator health, etc.). This course is open to advanced undergraduates who have taken AEDE 4310 (Environmental and Natural Resources Economics), AEDE 4001 (Managerial Economics) or ECON 4001 (Intermediate Microeconomics), as well as graduate students outside AEDE with a quantitative background (with permission).
