A simultaneously determined model for farm size and government payments along with the incorporation of a recursive impact of government payments and agricultural returns was used to examine farm size changes nationally and regionally. The results clearly demonstrated resource substitution...

The impact of the price of capital, nonfarm employment opportunities, and returns in agriculture on farm size was analyzed. A 10 region panel model using data for 1950-2000 was used. The impact of agricultural government payments was also examined. The results demonstrated the capital-labor...

Using 11 years of experimental crop yields by cropping systems and fertilizer level, a MOTAD frontier was developed. This analysis allowed yield, cost, and stability interactions arising from crop sequences to be implicitly included. Target-MOTAD, Safety-First, and undominated stochastic...

This paper addresses the issue of the shadow price of environmental bads treated as an undesirable output (normal input) with weak (strong) disposability in a two-stage estimation. Nebraska agriculture sector time series data used is spread over 1936-94. Results indicate the difference in the...

The importance of climate (temperature and precipitation) variability on Nebraska dryland winter wheat yield trend is examined. The use of short term (1956-1999) climatic divisional panel data (interspatial) and long term (1909-1999) state time series data (intertemporal) is to address the...

Using the non-parametric linear programming approach, this study examines overall efficiency gains due to diversification between crop and livestock enterprises for a sample of Kansas farms. Overall efficiency gains were decomposed into scope efficiency gains and scale efficiency gains. Farms...

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...

The existence of Weak Separability aggregates of inputs and outputs is tested using a Translog production and input requirement function for the Nebraska Agricultural sector for 1936-1994. A separability test was performed only after testing time series properties by comparing the null...

The objective of this paper is to examine the potential impacts of crop insurance on farm economic structure using Nebraska county level data from 1980-1998. Using a profit function we fit input demand and output supply equations accounting for insurance premiums and indemnities to examine the...

An over-parameterized statistical yield-switching-fraud model is developed. Over-parameterized procedures are reviewed. Five percent of 206,952 producers (thirteen percent in one state) have suspicious yield patterns, elect higher coverage, and increase total multiple-unit indemnifications up to...
