Seminário NOVAFRICA:
“Low Quality, Low Returns, Low Adoption: Evidence from the Market for Fertilizer and Hybrid Seed in Uganda”

Na quarta-feira, dia 6 de abril, pelas 14h30, o Centro NOVAFRICA convida Jakob Svensson, do Institute for International Economic Studies, para apresentar o seu trabalho sobre o impacto da qualidade dos fertilizantes e das sementes na produtividade agricultura.

To reduce poverty and food insecurity in Africa requires raising productivity in agriculture. Systematic use of fertilizer and hybrid seed is a pathway to increased productivity, but adoption of these technologies remains low. We investigate whether the quality of agricultural inputs can help explain low take-up. Testing modern products purchased in local markets, we find that 30% of nutrient is missing in fertilizer, and hybrid maize seed contains less than 50% authentic seeds. We document that such low quality results in zero average returns. If authentic technologies replaced these low-quality products, average returns for smallholder farmers would close to 80%. We further show, using a simple Bayesian learning model and data from our agricultural trials, that inferring quality from experimentation is difficult unless there are very large shortfalls in quality – findings that can help explain the low quality equilibrium we observe but also explain why the market has not fully collapsed.
