L’approche à deux étapes recourant aux modèles Data Enveloppent Analysis (DEA) et Tobit censuré a permis d’analyser l’efficacité des exploitations.
Unexpectedly lower yield outcomes (downside risks) challenge farmers’ use of external inputs that can enhance crop productivity. Using household-level panel data collected from Ethiopia, we estimated the effects of crop diversification through maize-legume intercropping/rotation on maize yield distribution and downside risk.
