This evaluation assesses the impact of modernizing process-control systems on reliability in developing contexts, implying a need for robust methodologies.
Key Points
The aim is to evaluate the impact of modernized process-control systems on operational reliability in West Africa.
Employed a difference-in-differences model for causal evaluation.
Analyzed panel data from treatment and control groups before and after intervention.
Specified a model measuring reliability index with cluster-robust standard errors.
Modernization significantly improved system reliability by 15 percentage points.
DiD estimator indicated a 0.15 increase in reliability index for treated systems.
Validated parallel trends assumption using pre-intervention data.
