| Agricultural productivity is known to decline with farm size in many developing countries. This may be a result of market imperfections, such as missing rural labor markets. On the other hand, there may be economies of scale in farming, due, for instance, to the importance of lumpy inputs. Hence, it is not theoretically obvious that the inverse relationship prevails in all situations. Indeed, several studies found non-monotonic relationships between productivity and farm size, with productivity decreasing with size up to a certain size and increasing beyond that point. This paper examines the relationship between Maize productivity and plot size in Zambia. If offers a unique empirical approach. First, it focuses on Maize, which is the major crop on... |
