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...

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...

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 recent survey indicated that many procedures view risk in a safety-first context. Traditional methods used to impose safety-first constraints in optimization models have often been difficult to implement. This is particularly true when endogenous decisions affect the distribution of the...
