The returns to scale for nineteen South Asian countries are estimated using window and cumulative rolling stochastic frontier regression analysis. The stochastic frontier analysis accounts for technical inefficiency of Hicks non-neutral technology production function in the estimation of the...

In the late 2000s, corn prices rose rapidly and were closely followed by prices of other major agricultural commodities. A widespread explanation for these market changes is an increased demand for corn in the production of ethanol, prompted by the introduction of programs intended to encourage...

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...

In the past few decades, U.S. agriculture has become increasingly dependent upon purchased inputs as farmers increased the use of chemicals and machinery while reducing labor. Dependence on various energy intensive inputs is currently so great that if supply channels are disrupted, production...
