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...

Efficient operation of agricultural credit markets is very important both for the producer as well as for the policy makers. DEA approach is used to calculate productivity analysis which allows decomposition of sources of productivity changes into efficiency and technical change. Measured...

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...

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...

Minimum regret solutions from alternative monthly sales for corn, wheat, and soybeans were determined. The data set involved eleven years of monthly prices for corn and soybeans and twelve years for wheat. The regret, risk (MOTAD), and expected value of the optimum regret solutions were compared...

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...
