2008 AEC - Empirical analysis of Agricultural Productivity Growth in Sub - Sahara Africa: 1961 - 2003


This study examined changes in agricultural productivity in Sub-Sahara Africa countries in the context of diverse institutional arrangements using Data Envelopment Analysis (DEA). From a time series which consists of information on agricultural production and means of production were obtained from FAO AGROSTAT and rainfall data from Steve O’Connell data base. The information was for a 43-year period (1961-2003); DEA method was used to measure Malmquist index of total factor productivity. A decomposition of TFP measures revealed whether the performance of factors productivity is due to technological change or technical efficiency change over the reference period. The study further examined the effect of land quality, malaria, education and selected governance indicators such as, control of corruption and government effectiveness on productivity growth. All the variables included in the model are significant with the exception of government effectiveness. They equally performed well in terms of expected relationship with TFP except education and land quality index which unexpectedly had an inverse relationship with TFP.
