Thomas L. Marsh is an internationally recognized expert in agricultural economics and trade. He uses quantitative methods to evaluate the effects of policy and intervention on markets.

His current research examines how public food-safety information influences consumer demand. He is also measuring the impact of livestock diseases (including bovine spongiform encephalopathy, foot-and-mouth disease, and E. coli) on human welfare and trade and gauging the outcomes of policy responses.

Professor Marsh co-organizes a working group that explores animal health economics. He serves as associate editor of the American Journal of Agricultural Economics, the premier scholarly journal in the field. In addition to his professorial roles in the School of Economic Sciences and the School for Global Animal Health, he directs the IMPACT Center at Washington State University, which seeks to address economic, social, political, and technical problems that affect the competitiveness of Washington’s agriculture and related sectors.
