This study estimates nonparametric non-stochastic Malmquist indices and a stochastic Fourier production frontier to examine agricultural productivity and its interactions with socio-political institutions in 41 sub-Saharan African countries during 1961-1999. We have learned from this study that on average, agricultural productivity in SSA was negative during the 1960's and 1970's, but has been positive during the last two decades. Institutions offer a significant explanation of at least some of the differential performance across countries.

本研究估计了非参数非随机的马姆奎斯特指数和随机的傅里叶生产前沿，以考察1961-1999年41个撒哈拉以南非洲国家的农业生产率及其与社会政治制度的相互作用。我们从这项研究中了解到，平均而言，SSA的农业生产力在60年代和70年代是负的，但在过去20年一直是正的。院校至少在一定程度上解释了各国表现的差异。
