The Department of Economic Science was founded in 1898 to teach economic theory as a truth of industrial life, and was very much concerned with applying economics to business and industry, particularly agriculture. Between 1910 and 1967 it showed the growing influence of other social studies, such as sociology, history, and political science. Today it encompasses the majors of Agricultural Business (preparing for agricultural finance and management), Business Economics, and Economics (for advanced studies in business or economics or for careers in financing, management, insurance, etc).
History
The Department of Economic Science was founded in 1898 under the Division of Industrial Science (later College of Liberal Arts and Sciences); it became co-directed by the Division of Agriculture in 1919. In 1910 it became the Department of Economics and Political Science. In 1913 it became the Department of Applied Economics and Social Science; in 1924 it became the Department of Economics, History, and Sociology; in 1931 it became the Department of Economics and Sociology. In 1967 it became the Department of Economics, and in 2007 it became co-directed by the Colleges of Agriculture and Life Sciences, Liberal Arts and Sciences, and Business.

Abstract
During the last decade, two concerns have been raised about the future of U.S. crop production. These concerns are: (a) Will the United States have enough land available in the future that is suitable for crop production? and (b) What will future crop yields be? Future U.S. crop production is highly dependent upon both these issues;The real problem may not be the quantity of future crop production, but rather the price of the quantity that is available. The development of a model to answer this question is one of the objectives of this study. The other objective is the projection of prices and quantities for barley, corn, oats, sorghum, soybeans, and wheat for the year 2000 under alternative yield and land availability assumptions;An iterative model based on the theory of tatonnement process of market adjustments is developed using a linear programming model to stimulate the behavior of producers and demand equations estimated econometrically to stimulate the behavior of consumers. The iterative model starts at an arbitrary level of demand for each commodity and solves for approximate equilibrium prices and quantities;The iterative model is used to estimate approximate equilibrium prices and quantities for barley, corn, oats, sorghum, soybeans, and wheat and supply prices for corn silage, sorghum silage, legume hay, other hay, and cotton for the year 2000. Seven scenarios consisting of three alternative yield levels and three alternative levels of land constraints are run and analyzed;The results from the seven scenarios suggest that the future equilibrium prices and quantities are highly dependent upon the assumptions made about future crop yields and future cropland availability. The highest equilibrium price for barley, corn, oats, sorghum, wheat, and soybeans is 182.1, 158.8, 145.3, 165.1, 182.4, and 208.9 percent higher than the lowest equilibrium price, respectively.
