Nonparametric Estimates Of The Components Of Productivity And Profitability Change In U.S. Agriculture
TL;DR: In this paper, a decomposition of the TFP index can be further decomposed into an index of technical change and various indexes of efficiency change, which can be unambiguously interpreted as measures of either technical change or efficiency change.

Does Excluding Cross-commodity Interactions Matter? Beef and Lamb in Australia
TL;DR: In this article, the effects of exogenous demand and supply shifters on the wholesale-farm price ratio in two closely related industries, beef and lamb, are examined in a Gardner type of model and the effect of excluding consideration of the cross-commodity interactions is measured.

Deterministic Frontier Analysis
TL;DR: In this paper, the authors explain how to estimate and draw inferences concerning the unknown parameters in so-called deterministic frontier models (DFMs) and how the estimated parameters can be used to predict levels of efficiency and analyse productivity change.
