The Agricultural Productivity Gap *
根据国民账户数据，非农业部门的人均增加值通常远高于农业部门，这暗示劳动力配置严重失衡。本文利用微观数据，在考虑工时、人力资本及家庭调查产出后，发现这一差距依然显著存在。
Abstract According to national accounts data, value added per worker is much higher in the nonagricultural sector than in agriculture in the typical country, particularly in developing countries. Taken at face value, this “agricultural productivity gap” suggests that labor is greatly misallocated across sectors. In this article, we draw on new micro evidence to ask to what extent the gap is still present when better measures of sector labor inputs and value added are taken into consideration. We find that even after considering sector differences in hours worked and human capital per worker, as well as alternative measures of sector output constructed from household survey data, a puzzlingly large gap remains.
