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.
