Ag Econ Students Named as Top Freshmen for 2017/2018
Eleven department of agricultural economics agribusiness sophomores were among the 40 students who were recently named as OSU Top 20 Freshmen Men and Top 20 Freshmen Women and as CASNR Top 20 Freshmen Men and Top 20 Freshmen Women for 2017/2018.

Five department of agricultural economics agribusiness sophomores were among the 20 students who were recently named as OSU Top 10 Freshmen Men and Top 10 Freshmen Women for 2017/2018.

The top 10 freshmen men are: Cale Hinrichsen, Westmoreland, Kansas; Luke Muller (agribusiness/plant and soil science), Altus; Truitt Taylor, South Coffeyville; and Hunter Thomas, Newkirk.

The top 10 freshmen woman is: Erica Wiebe, Hooker.Previously, these five students plus six additional department sophomores were among the 40 students who were named as OSU Top 20 Freshmen Men and Top 20 Freshmen Women for 2017/2018

These top 20 freshmen men are: William Church, Fairview; Zachary Guy, Meeker; Kade Killough, Stillwater; and Dalton Miller, Blanchard.

These top 20 freshmen women are: Brooklan Light, Enid; and Nyla Maere (agribusiness/animal science), Bloomington, Illinois.

The Achafoa Chapter of Mortar Board at Oklahoma State University oversees the selection and recognition of the Top 20, and Top 10 Freshmen Men and Women on the OSU campus.

The Ag Econ Department Welcomes Three New Faculty Members
Amy Hagerman
Amy Hagerman has joined the department as an assistant professor with a joint extension and research appointment. She will be working in the general area of farm bill policy and agricultural/public policy. She is currently researching distribution methods to provide information regarding changes to the farm bill to interested parties in Oklahoma. In addition to closely watching the progress of the 2018 Farm Bill, Hagerman continues to measure economic consequences of animal diseases, and other extreme events, on agriculture.

Dr. Hagerman is returning to OSU, where she received her bachelor’s degree in agricultural economics in 2004. She received her master’s and doctoral degrees in agricultural economics from Texas A&M University.

She most recently worked for the United States Department of Agriculture in Fort Collins, Colorado, where she was a Supervisory Agricultural Economist for the Epidemiologic and Economic Modeling Team in the Center for Epidemiology and Animal Health, a part of the Animal and Plant Health Inspection Service’s Veterinary Services.

When asked what drew her to study agricultural economics, she replied, "Agricultural economics touches everyone, whether they realize it or not. This field is full of interesting and important questions. I get the opportunity to serve farmers and ranchers in Oklahoma by providing information that can help them better understand policies and manage risks in their businesses."

On returning to Stillwater, Hagerman related that, "My husband Colby and I are happy to be back in Stillwater with our three children. We feel like we have come home."

Dayton Lambert
Dayton Lambert is a professor and holds the Willard Sparks Chair in Agribusiness. He comes to OSU from the Department of Agricultural and Resource Economics at the University of Tennessee, where he was a professor. Dr. Lambert’s research interests are production economics, regional economics, decision theory, and econometrics. He holds a joint research and teaching appointment.

His education includes a B.A. in Anthropology from Miami University of Ohio, a M.A. in Cultural Anthropology from Rutgers University, a M.S. in Fisheries and Allied Aquaculture from Auburn University, and a Ph.D. in Agricultural Economics from Purdue University. He served as a United States Peace Corps Volunteer in Burundi and Gabon, Central Africa.

What appeals to him most about agricultural economics is its transdisciplinary approach towards identifying and solving problems relevant to farm resources, food and fiber production, and their markets. His academic training in anthropology was oriented towards technology adoption, human-environment interactions, and common pool resource institutions.

Lambert joined the United States Peace Corps after obtaining his degrees in anthropology. During his service in Central Africa, he worked with smallholder farmers to integrate aquaculture and small animal production systems into their operations. A key constraint to increased productivity was fingerling quality. During this time, he developed an avid interest in broodstock management, fingerling production, and genetics.

In 2000, he began graduate studies in Purdue University’s Department of Agricultural Economics and had an opportunity to research two relatively new (at that time) fields in agricultural economics – precision agriculture and spatial econometrics. Precision agriculture paved the way for his focus on applied production economics. Spatial econometrics provided a comparative advantage with respect to tackling models to analyze regional economies, international trade, urban-rural dynamics, firm location, and land use change.

Lambert’s current research at OSU continues a USDA/NIFA project with University of Tennessee agricultural economists, soil scientists, and civil engineers, titled “Increasing the Resilience of Agricultural Production in the Tennessee and Cumberland River Basins through More Efficient Water Resource Use.” Two surveys he is presently studying – one of West Tennessee row crop producers, the other of Tennessee beef cattle operators – ask producers about their knowledge of and interest in using management practices that improve soil moisture holding capacity.

On his research horizon are the following topics:

  • Consumers and biobased products
  • Farm and agribusiness entry-exit
  • Consumers and gene editing technologies
  • Agribusiness mergers and acquisitions
  • Water, many users, and uncertainty
  • New approaches for estimating U.S. agricultural productivity
  • Managing herbicide resistance


  • Lixia He Lambert
    Lixia He Lambert is a research associate with a joint research and teaching appointment. Her research focus areas include environmental and resource economics and production economics and sustainable development. She will be teaching two undergraduate ag econ courses this fall, Quantitative Methods (AGEC 3213) and Environmental Economics and Resource Development (AGEC 4503).

    Currently, Lambert is working on a NIFA project, titled "Increasing the Resilience of Agricultural Production in the Tennessee and Cumberland River Basins Through More Efficient Water Resource Use." "This is a collaborative project with researchers from the University of Tennessee," she says. "My role in the project is to develop an agricultural sector model for Tennessee to evaluate how changes in water availability affect crop selection and irrigation decisions."

    Lambert was previously a Research Scientist in the Department of Agricultural and Resource Economics at the University of Tennessee in Knoxville, Tennessee.

    She is also working on a project sponsored by DuPont Tate & Lyle to develop a bioprocessing facility-to-farm supply chain model that determines least cost transportation routing for spent microbial biomass (a residual from fermenting corn to produce bio-polymer precursors) to field crops as a soil amendment.

    At OSU, Lambert says, she plans to collaborate with other researchers in three main areas: the development and advancement of biomass materials for energy and other bioproduct markets; the optimal allocation of agricultural water resources; and operations research on production of value added agricultural products.

    Lambert’s education includes a Diploma in Fermentation Engineering from Huazhong Agricultural University in Wuhan, China, a M.S. in Agricultural Economics and Management from Huazhong Agricultural University in Wuhan, China, a Ph.D. in Agricultural Economics from Purdue University in West Lafayette, Indiana, and a M.S. in Industrial Engineering from the University of Tennessee in Knoxville, Tennessee.
