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

The dissertation consists of three essays that analyze production efficiency, size effects and human mobility using a panel of 591 Chinese agricultural households in the later 1990s.;The first essay estimates technical efficiency through the framework of a translog stochastic production frontier with a behavioral inefficiency component. The results reveal a decreasing trend of output elasticities with respect to labor and fertilizer. The marginal effects of inefficiency terms show significant output gains by eliminating land fragmentation, improving access to education in rural area, and promoting specialization and mechanization.;The second essay examines land heterogeneities and the empirical inverse relationship in developing countries between farm size and productivity. When we utilize the egalitarian principle during land allocation in China and use imputed quality constant land rather than actual land area in the regression, the inverse relationship between farm size and productivity disappears. Hence, the strong inverse relationship that some studies have found is undoubtly due to a number of methodological problems, i.e., the failure to account properly for land quality differences.;The third essay analyzes the decision-making of rural Chinese households on whether to allocate efforts exclusively to the family farm, taking off-farm work locally or migrating to another region. We observe statistically significant state dependence between the current period response and past behavior. Simulated probability changes support our hypothesis that the average schooling of household labor and household size play important roles in Chinese farm household job-location decisions.;The dissertation advances several econometric methodologies. We obtain the close form of marginal effects of inefficiency terms in Battese & Coelli (1995) model, as well as their variance estimator. We propose two methods to summarize curvature conditions of flexible functional forms. In the second essay, we apply Hahn-Hausman (2002) test to examine the validity of the instrumental estimation. We derive the Murphy-Topel two-step estimation variance estimator in the linear case. The third essay extends the dynamic discrete choice model of Wooldridge (2002a,b) to trichotomous setting. We use the maximum simulated likelihood estimation to reduce the computation burden in estimating the random effects multinomial logit model.
