Crop diseases and how they are managed can have a large impact on agricultural productivity. This paper discusses the … effects on agricultural productivity of Verticillium dahliae, a soil borne fungus that is introduced to the soil via infested … important implications for agricultural productivity …

In this paper we show that the study of the farm size-productivity relationship hinges on the choice of productivity … measure. Our main insight is that using yields, a partial measure of productivity, may not be informative for the size-productivity … relationship because, in addition to total factor productivity, yields pick up input markets distortions and deviations from …

Management has a large effect on the productivity of large firms. But does management matter in micro and small firms … Bangladesh, Chile, Ghana, Kenya, Mexico, Nigeria and Sri Lanka. We show that variation in business practices explains as much of … the variation in outcomes – sales, profits and labor productivity and TFP – in microenterprises as in larger enterprises …

A vast firm productivity literature finds that otherwise similar firms differ widely in their productivity and that …,000 agricultural plots across four countries in Africa to study the size, source, and persistence of productivity dispersion among … smallholder farmers. Applying standard regression-based approaches to measuring productivity residuals, we find much larger …
