Multilevel regression analyzes efficiency gains in smallholder farms, indicating significant productivity increases from extension services.
Smallholder farming systems in Tanzania have been studied for their efficiency gains, but methodological evaluations are limited. A multilevel regression model was employed to analyse farm-level data collected from to . The model incorporates both fixed effects for individual farmers and random effects for geographical regions, accounting for potential heterogeneity across different sites. The analysis revealed a significant increase in productivity by approximately 15% after the implementation of agricultural extension services, with confidence intervals suggesting a robust stability in these gains. Multilevel regression provided a nuanced understanding of efficiency dynamics and highlighted the importance of contextual factors in farm performance. Further research should explore longer-term impacts and broader application across different regions to validate these findings.
