This paper deals with the estimation of a random coefficient model. The virtue of this approach is that it considers firm heterogeneity, which conventional SFA models do not. When the model is applied to Polish farms, the results indicate that the conventional random and fixed effect models...

We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 40 years, looking for evidence of recent changes in growth patterns using a nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan...
