Current Research Areas

Healthy, sustainable + fair supply Chains

Many people care about the impacts their food purchases have on their own health, the environment and other people, and they buy products according to these values. I consider who is producing and purchasing these products, the incentives driving their decisions, and the welfare impacts of production and consumption.

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 and other types of power (e.g., voting power) in the agricultural supply chain and food systems.

Orgs + networks in the food system

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.
