Agricultural productivity in developing countries
研究了18个发展中国家1961-1985年间的农业生产力变化，使用非参数Malmquist指数和参数生产函数，发现至少半数国家农业生产力下降。
Abstract This paper examines changes in agricultural productivity in 18 developing countries over the period 1961–1985. We use a nonparametric, output‐based Malmquist index and a parametric variable coefficients Cobb‐Douglas production function to examine, whether our estimates confirm results from, other studies that have indicated declining agricultural productivity in LDCs. The results confirm previous findings, indicating that at least half of these countries have experienced productivity declines in agriculture.
