This article incorporates an upper partial moment concept into a linear programming model to impose safety-first environmental constraints. The model is linear and deterministic, treats a discrete sample as an empirical distribution, and optimizes over the column space. It allows a decision...

This study computes and decomposes farm efficiency for Missouri grain farms using a nonparametric cost frontier approach. The results indicate that the overall cost efficiency is 58 percent, suggesting significant inefficiencies exist among sample farms. Misallocation of inputs and improper...
