An Intercountry Comparison of Agricultural Production Efficiency
比较不同国家农业总生产率，发现同一发展阶段国家间效率差异小于劳动生产率差异，但不同发展阶段间差异很大，且发达国家与发展中国家差距在扩大。
Abstract Intercountry cross‐section comparison of total productivity in agriculture showed that differences in production efficiency were small relative to differences in labor productivity among countries at a same stage of economic development but very large among different stages of development. Moreover, the large differences in total productivity between the developed and the less developed countries widened further during the past two decades. The results suggest a hypothesis that agriculture in the less developed countries as a whole has not yet entered the phase of “modern economic growth” à la Kuznets.
