Abstract

Agricultural productivity in Sub-Saharan Africa has been largely stagnant over the past half century. The lack of progress is often attributed to the lack of adoption of modern inputs, such as chemical fertilizers and hybrid seeds. We conduct an experiment designed to uncover the efficiency of the market mechanism at allocating chemical fertilizers to farmers. We find that average returns to fertilizer amongst non-adopters are low, but there is a group of farmers with high returns who would be induced to adopt fertilizer with a mild subsidy. In that sense we find the market for fertilizer to be inefficient, and we calculate the optimal subsidy to be 30% of the market price. Further, we show that this inefficiency is driven by liquidity constraints: once liquidity constraints are removed, the optimal subsidy is 0.
