| 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)... |

| Two double-limit tobit models are used to identify significant risk factors that most affect farm-raised catfish losses from weather-related events and from disease outbreaks. Results of the weather loss model indicate that the variables for operator education level, number of ponds, pond water depth, production management strategy, past experience with severe losses from low oxygen levels from off-farm power outages, past experience with severe losses from diseases, and being in the South are statistically significant. Results of the disease loss model indicate that the variables for operator experience and pond water depth are significant. De-velopment of models explaining weather and disease losses through observable variables pro-vides a better... |

| A two-stage simultaneous equation is utilized to model the choice of whether to purchase insurance and the choice of whether to purchase yield or revenue insurance using subjectively elicited survey data. Our results show an elasticity of demand for crop insurance that remains largely unchanged from earlier estimates (-0.40), but the elasticity for choices between yield and revenue insurance is found to be relatively more elastic (-0.76). Finally the link between adverse selection and the demand for insurance is examined. |

| 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. |

| 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. |
