Simple Econometrics of Pesticide Productivity
扩展了Lichtenberg-Zilberman损害控制技术,提出多产出模型,利用美国农业数据估计害虫损害,发现损害远低于以往估计。
Abstract This paper develops a multioutput generalization of the Lichtenberg‐Zilberman damage‐control technology. The dual representation of the technology is shown to be conditionally additive in the price of abatement activities and other prices. An econometric procedure for estimating the dual technology is developed and applied to an aggregate U.S. agricultural data set. The conditionally additive nature of the model allows estimation of pest damage from the dual technology. Our estimates of aggregate U.S. pest damage are much lower than previous estimates.
