| This paper has a two-fold contribution. First, it examines the importance of accounting for (in)efficiency in the estimation of primal production function on the input elasticities, technical change, and calculation of returns to scale. Second, it applies a variant of the rolling regression technique to identify time-varying input elasticities, technical change, and return to scale. Empirical application to the Asian agriculture sector using Food and Agricultural Organization data from 1961-2005 indicates returns to scale are underestimated by the traditional pooled and panel models. Further, the time-varying estimates of input elasticities, technical change, and returns to scale indicate variations with each additional year of information. |

| This paper examines the possibility that insurance for row crops, livestock, and aquaculture can be used effectively to encourage producers to adopt practices that will improve environmental behavior. Examples of agricultural environmental insurance are provided and considered in the context of alternative policy mechanisms. The current state of agricultural insurance and the nonagricultural environmental insurance market are explored. We also lay out the characteristics of an insurable risk along with the theoretical basis of insurance provision. An empirical example of an environmental insurance design is provided, and the behavioral implications of such a design are examined. Finally, we discuss important considerations that should be evaluated... |

| Millions of pounds of fresh fruits, vegetables, cut flowers, herbs, and other agricultural and food products enter the United States via commercial shipments from other countries every year. Although these items appear harmless, there could be hidden threats in that baggage and in those truckloads, trainloads, and containers of fresh and processed food items that could seriously threaten U.S. agriculture, its natural resources, and its economy (U.S. Customs and Border Protection 2007). Food imports play a major role in the success and competitiveness of various agribusiness firms in the United States. For example, food imports generate income, employment, output, and taxes and provide consumers with lower-priced products than those produced or purchased in... |

| System of input demand functions is estimated to examine the impact of farm program payments on farm economic structure. Influence of farm program payments on input resource use for the time periods corresponding to the thirteen farm bills in effect since 1938 is also examined. Empirical application to Nebraska agriculture sector for the period 1936-2004 indicate positive impact of farm program payments on farm real estate, breeding livestock and other inputs. Negative influence of farm program payment on the use of farm equipment, farm labor, farm inputs, chemicals and energy was observed during the same period. |

| Geographical information systems and econometric tools were used to determine the socioeconomic impacts of bypasses in Atlanta-Birmingham Metropolitan area. Mean household income and per capita income of county is separately used as a proxy for anticipated bypass impact as a function, of socioeconomic variables: farm income, farm employment, non-farm employment, age groups, and population density. The cross-sectional and the time series data were pooled together and estimated as panel data. Results indicate that most of these variables have positive impacts on growth. |

| Issues on energy have recently dominated the economic decisions of several states across the U.S. economy and states in the southeastern region of U.S. are no exception. Almost all the states in the southeast import virtually all of their fuel resources from the Gulf Coast representing an annual financial diversion of several billions of dollars some of which could be used to develop domestic, alternative energy resources. The focus of this study was to determine the potential substitution between renewable energy and conventional energy forms in the southeast of U.S. We developed a system of factor share equations using translog cost function. The system of equations was estimated using a pooled iterative Non-linear Seemingly Unrelated Regression (SUR)... |

| 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. |
