AGRICULTURE IN AN ECOSYSTEMS FRAMEWORK AgEcon
Aillery, Marcel P.; Hrubovcak, James; Kramer, Carol S.; Shoemaker, Robbin A.; Tegene, Abebayehu.
By broadening the definition of an ecosystem to include economic activities, can we better characterize the interactions and relationships among agricultural activities and important indicators of ecological system health? This paper addresses research approaches for assessing the role of agriculture in an ecosystems context. Environmental regulation and resource management policies have heightened the interest in understanding interactions among agricultural activities and the natural resource base, including the impacts of agriculture on environmental quality and the impacts on agriculture of ecosystem restoration efforts. What are the most meaningful indicators of environmental quality? Which agricultural practices and policies should be considered,...

Crop Genetic Resources: An Economic Appraisal AgEcon
Day-Rubenstein, Kelly A.; Heisey, Paul W.; Shoemaker, Robbin A.; Sullivan, John; Frisvold, George B..
Crop genetic resources are the basis of agricultural production, and significant economic benefits have resulted from their conservation and use. However, crop genetic resources are largely public goods, so private incentives for genetic resource conservation may fall short of achieving public objectives. Within the U.S. germplasm system, certain crop collections lack sufficient diversity to reduce vulnerability to pests and diseases. Many such genetic resources lie outside the United States. This report examines the role of genetic resources, genetic diversity, and efforts to value genetic resources. The report also evaluates economic and institutional factors influencing the flow of genetic resources, including international agreements, and their...

ECONOMIC ISSUES IN AGRICULTURAL BIOTECHNOLOGY AgEcon
Shoemaker, Robbin A.; Harwood, Joy L.; Day-Rubenstein, Kelly A.; Dunahay, Terry; Heisey, Paul W.; Hoffman, Linwood A.; Klotz-Ingram, Cassandra; Lin, William W.; Mitchell, Lorraine; McBride, William D.; Fernandez-Cornejo, Jorge.
Agricultural biotechnology has been advancing very rapidly, and while it presents many promises, it also poses as many questions. Many dimensions to agricultural biotechnology need to be considered to adequately inform public policy. Policy is made more difficult by the fact that agricultural biotechnology encompasses many policy issues addressed in very different ways. We have identified several key areas — agricultural research policy, industry structure, production and marketing, consumer issues, and future world food demand — where agricultural biotechnology is dramatically affecting the public policy agenda. This report focuses on the economic aspects of these issues and addresses some current and timely issues as well as longer term issues.

Public Investment Policy in Life-Science Research AgEcon
Wang, Chenggang; Xia, Yin; Shoemaker, Robbin A.; Buccola, Steven T..
The article presents a dynamic model of research investment. This model allows us to examine three important channels through which public investment policy can affect the private sector's research investment, that is, the productivity, replacement, and wage effects. Two alternative empirical approaches are introduced to implement the model. Through a unified examination of the productivity, replacement, and wage effects, the empirical estimation of this model will provide insight into whether public-sector research investment crowds in or crowds out private-sector research investment.

THE EFFECT OF FEEDGRAIN PROGRAM PARTICIPATION ON CHEMICAL USE AgEcon
Ribaudo, Marc; Shoemaker, Robbin A..
Economic incentives created by the commodity programs are hypothesized to cause program participants to apply agrichemicals at greater rates than nonparticipants. Corn producers who participate in the USDA feedgrain program are shown to apply nitrogen, herbicides, and insecticides at statistically greater rates than those who do not participate.
