This paper develops a method for decomposing total factor productivity growth in separable production technologies and uses it to examine the role of pest-damage prevention on agricultural productivity. The rate of technical change is decomposed into output-enhancing and damage-preventing components. Growth accounting cannot provide separate estimates of these two components of technical change, and instead a parametric model is developed based on the dual cost function. The proposed model captures both components of technical change, properly accounts for environmental effects, and also accommodates the presence of capacity utilization and scale biases. The empirical application of the model is to a sample of Cretan olive-oil producers, and the results show that output-enhancing technical change is more important than damage-preventing technical change in explaining observed total factor productivity (TFP) changes. The second largest source of TFP growth is due to the scale effect. 相似文献

This study attempts to examine issues related to the existing adverse relationship between regional economic development and
natural environment protection. For doing so, a regional environmental input-output model for the region of central Macedonia
in northern Greece is constructed in order to quantify the direct and indirect undesirable negative effects of the production
process in the natural environment. The results suggest that there is a considerable trade-off between economic development
and environmental deterioration which should be taken into account when policy decisions are made.
