| This paper examines changes in agricultural productivity in 10 Subsaharan countries. The relative performance of agricultural sector was gauged using data envelopment analysis. From a panel data set of the 10 countries which included the 28-year period 1972-1999, mathematical programming methods were used to measure Malmquist indexes of total factor productivity. It was found that, during that period, total factor productivity have experienced a negative evolution in sample countries. A decomposition of those measures suggest that, most of the weak performance of factors productivity is attributable more to technological change than technical efficiency change. French-speaking countries better succeeded to raise their productivity than English-speaking... |

| This paper presents empirical evidence to show how socioeconomic factors affect the adoption of and investment in agrochemicals in the cocoa sector of Côte d’Ivoire. The analysis uses primary farm-level data collected in 2002 from a nationally representative sample of more than one thousand cocoa farmers. The study describes the status of the adoption of various chemical inputs and uses a multiplicative heteroscedastic Tobit model to identify and quantify the impact of the socioeconomic environment on the incentive to invest. The results generally show that farmer, household and village characteristics are all important in explaining the farmers’ decisions. The paper concludes by outlining a number of implications for strategic targeting of farmers and... |
