with Ursula T. Aldana, Paul Laris: w17801
Since independence a quiet revolution has taken place in maize production in the Sahel with Mali increasing production more than ten-fold and yields going up ~2% a year. This research work uses farm level panel data from southern Mali's maize growing regions to demonstrate this success in agricultural production and technological change. We analyze the determinants of production to unpack increases in input use from technological change. The estimations show that farmer adoption of increased fertilizer use has driven much of the productivity growth rather than the adoption of improvements in seeds and management. Additionally, we find strong evidence of observed and unobserved heterogeneity, which affects both the choice of fertilizer amounts and the marginal returns to fertilizer use. ...
