The impact of access to agricultural advisory services on input use and farm performance: Evidence from Senegal

Performant agricultural advisory services (AAS) in Africa are crucial for improving the agricultural productivity and food security of the farm households. Yet, evidence‐based study on the impacts of AAS on farm performance are scarce, especially in West African countries. This study evaluates the impact of access to AAS on input use and farm performance in Senegal, employing the instrumental variable and control function approaches accounting for selection bias. The approaches are also employed to several sub‐samples to see if the impacts are heterogeneous across crop types and fertilizer use, and matching techniques are applied to test the robustness of the results.
