AgEcon Search: Research in Agricultural and Applied Economics collects, indexes, and electronically distributes full text copies of scholarly research in the broadly defined field of agricultural economics including sub disciplines such as agribusiness, food supply, natural resource economics, environmental economics, policy issues, agricultural trade, and economic development.
The majority of items in AgEcon Search are working papers, conference papers, and journal articles, although other types such as books chapters and government documents are included. AgEcon Search will serve as the permanent archive for this literature and encourages authors and organizations to use this electronic library as the storehouse for additional appropriate scholarly electronic works.
AgEcon Search is co-sponsored by the Department of Applied Economics and the University Libraries at University of Minnesota and the Agricultural and Applied Economics Association.
The site has received encouragement and financial support from:
Agricultural Economics Reference Organization
Agricultural and Applied Economics Association
European Association of Agricultural Economists
Farm Foundation
International Association of Agricultural Economists
USDA Economic Research Service

History
AgEcon Search began in 1995 as an experiment to see if it were possible to use the internet to archive, index and deliver on demand, full text working papers produced by university agricultural economics departments. The first papers were from agricultural economics departments at Minnesota and Wisconsin. These early papers predated the World Wide Web and were mounted on a GOPHER server in WordPerfect format. The project was (and still is) a cooperative project of the University of Minnesota Libraries, the Department of Applied Economics at the University of Minnesota and the Agricultural and Applied Economics Association (AAEA). The Farm Foundation and the Economic Research Service of the U.S. Department of Agriculture provided financial support in the beginning of the project. Patricia Rodkewich and Louise Letnes managed AgEcon Search until Patricia's retirement in 2001, when Julie Kelly joined the AgEcon Search team. Erik Biever also served on the original AgEcon Search team, providing valued technical services and guidance. The members of the Agricultural Economics Reference Organization endorsed the efforts of AgEcon Search early on and have been instrumental in expanding the use of AgEcon Search in their respective institutions.
Since its inception AgEcon Search has operated as a distributed network, with each institution designating a member of their organization to submit papers on their behalf. With this model, costs for maintaining the system were kept low and institutions do not have to pay membership fees for participation. In the cases where an institution had no central person to act as the network member, a fee has been charged for AgEcon Search staff to submit papers. The first organization to choose this option was the Agricultural and Applied Economics Association, which since 1997 has been contracting with AgEcon Search to post its annual conference papers.

Omitting spatial characteristics such as proximity to amenities from hedonic land value models may lead to spatial autocorrelation and biased and inefficient estimators. A spatial autoregressive error model can be used to model the spatial structure of errors arising from omitted spatial effects. This paper demonstrates an alternative approach to modeling land values based on individual and joint misspecification tests using data from Roanoke County in Virginia. Spatial autocorrelation is found in land value models of Roanoke County.
Land Degradation in the Sahel: An Application of Biophysical Modeling in the Optimal Control Setting
Low-input farming practices in many parts of the developing world have pushed cultivation onto marginal lands. Sustainability of already fragile ecosystems is threatened. Farmers place a high priority on satisfying subsistence food needs with on-farm production. Population pressure is high throughout much of Sub-Saharan Africa. Farmers in those regions are challenged by the need to put continually more food on their table over the coming years. An optimal control model was developed to investigate alternative farming practices within this setting.
Do Homebuyers Care about the 'Quality' of Natural Habitats?
We study if homebuyers in Tucson, Arizona care about the condition of natural habitats and if they have preferences between natural and manmade habitats. Using field work data we examine whether homebuyers willingness to pay is influenced by the biological condition of the neighboring riparian habitat and how homebuyers value alternative manmade green areas, specifically golf courses. We also explore the relationship between the field data and remote sensing vegetation indices.
Minnesota Farm Real Estate Sales: 1990-2004
This publication is a snapshot of the Minnesota Farm Real Estate Sales web site (http://www.apec.umn.edu/faculty/sjtaff/salesstudy) as of June 2, 2005. It will be formally "reissued" (the web site will be recaptured) each Spring, as new sales data become available. We no longer distribute a separate farm real estate report in the Minnesota Agricultural Economist (now the Minnesota Applied Economist). The site consists largely of graphs and tables summarizing sales over the past fifteen years.
ECONOMIC ANALYSIS OF AGRICULTURAL LAND CONVERSION IN THE SOUTHEAST
We estimate a system of equation model to understand the factors that influence the loss of agricultural land to non-agricultural uses in the Southeast United States. This is done by analyzing the complex relationship between population, employment, and agricultural land density for the 1990-2000 period. From the results, it can be noted that growth in employment over time and the expansion of residential housing have to be compromised with the agricultural sector on the use and allocation of land.
