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...

We demonstrate that Theil-type variance corrections are required to obtain consistent marginal effect estimates in Nelson-Olsen's two-stage limited dependent variable (2SLDV) model. As Theil's residuals-based corrections are infeasible with 2SLDV, we present variance correction procedures shown...

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...

This paper has a three fold contribution to the existing literature - 1) Indian state level sorghum input and output data for the period 1970-71 to 2000-01 is collected, 2) non-parametric and parametric productivity measures are estimated, and 3) examine the impact of percent acreage under high...

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...

Gravity models were developed to estimate the potential bilateral exports of cocoa under trade liberalization by the sixteen major cocoa producing countries to the US using panel data from 1989 to 2003. The results indicate that differences between resource endowment, relative size of economies,...

The robustness of the multiple imputation of missing data on parame- ter coefficients and efficiency measures is evaluated using stochastic frontier analysis in the panel Bayesian context. Second, the implications of multi- ple imputations on stochastic frontier analysis technical efficiency...

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...
