Abstract

Using a non-parametric linear programming approach, our contribution is (1) to examine the impact of incorporating risk in efficiency analysis and (2) to compare the efficiency measures with and without risk for continuous and rotation cropping systems. The model uses Nebraska cropping system data for the period, 1986-2000. Results indicate lower efficiency gains are realized with the incorporation of risk. The t-test at the 5% level of significance examining if efficiency measures are significantly different from one is also reported.
