This article analyzes the productivity growth in Korean agriculture with data on multiple crops, over the five years, from 1998 to 2002. Measurements are obtained from the estimation of a stochastic multi-output distance function. This study corrects for sample selection bias in the context of a translog functional form that appears when some farms produce only a subset of the potential outputs. The results find that technological change has caused a significant productivity change. Larger farms experience the highest rate of productivity growth by the greatest rate of scale effect. More human capital also leads higher productivity growth rates.
Abstract
This article analyzes the productivity growth in Korean agriculture with data on multiple crops, over the five years, from 1998 to 2002. Measurements are obtained from the estimation of a stochastic multi-output distance function. This study corrects for sample selection bias in the context of a translog functional form that appears when some farms produce only a subset of the potential outputs. The results find that technological change has caused a significant productivity change. Larger farms experience the highest rate of productivity growth by the greatest rate of scale effect. More human capital also leads higher productivity growth rates.
