Abstract
This study evaluates regional monitoring networks in Kenya aimed at reducing logistical risks through a randomized field trial. A randomized field trial was conducted across various regions of Kenya. Data were collected using sensors and surveys to measure logistics performance metrics, including delivery times and cost efficiencies. The analysis revealed a significant improvement (p < 0.05) in delivery times by 12% with the monitored networks compared to non-monitored areas, indicating enhanced operational effectiveness. This randomized trial demonstrated that regional monitoring networks can effectively reduce logistical risks and improve performance metrics in Kenya's supply chain environment. Based on these findings, it is recommended that further investment be directed towards expanding the monitored regions to achieve broader risk reduction across Kenya’s logistics sector. Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
