Analysis of Elderly In-Migrants In Tennessee 31
Zhou, Xia (Vivian).
The idea of elderly in-migrants as an important factor or stimulus to local economic development (Serow, 2001) has been confirmed by quite a few studies such as Bennett (1993); Carlson, Junk, Fox, Rudzitis, & Cann (1998); Day & Barlett (2000); Hodge (1991); Serow & Haas (1992); and Stallmann, Deller, & Shields (1999). Large-scale elderly in-migrants can bring several benefits to local economy. First, they can increase property and sales taxes, counties' largest source of revenues, without directly increasing their greatest expense such as public education; also, in-migrant retirees as a large portion of elderly do not compete for jobs so that most of counties consider them as net economic assets (Day & Barlett, 2000; Glasgow, 1991;...

Dynamic Optimization of Fertilizer Application with Carryover and Runoff 31
Zhou, Xia (Vivian); Clark, Christopher D.; Lambert, Dayton M..
The Economics of fertilizer application has been an interesting issue in regard to crop production (Kennedy et al., 1973). Understanding the temporal dynamics complicates the issue along two dimensions: fertilizer carryover and fertilizer runoff. Fertilizer carryover measures the amount of fertilizer applied in the previous period that is available for crops in current growing period (Kennedy et al., 1973). Fertilizer runoff refers to fertilizer leaving the ground and flowing into water bodies. Thus, the optimal quantity of fertilizer to be applied in the current period depends on the amount of previous application, runoff, and carryover. Because fertilizer carryover and runoff makes optimization of application a complicated intertemporal problem, static...

Demand Analysis for Shrimp in the United States 31
Zhou, Xia (Vivian); Shaik, Saleem.
This paper analyzes the demand for shrimp along with beef, pork, and chicken in the US food market, which contributes much to predicting supply strategies, consumer preferences and policy making. It focuses on the own and cross relationship between the expenditure share and price, income changes. An Almost Ideal Demand System (AIDs) model and two alternative specifications are used to estimate a system of expenditure share equations for shrimp, beef, pork, and chicken. Empirical results indicated that some insignificant slope coefficients and inappropriate signs of them did not comply with microeconomic theory. This could be caused by heteroscedasticity, autocorrelation, a limitation in the data used, or shrimp is a commodity that is quite different.
