Reproducibility package for Neither Too Little, nor Too Late: Restructuring as a Reflex for Outcomes

We examine whether project restructuring improves World Bank project performance. Using panel data on Implementation Status and Results (ISR) ratings, we combine two-way fixed effects with the PanelMatch estimator to address concerns that restructurings are endogenously timed. Restructurings consistently raise ISR ratings, and these gains persist across successive reporting cycles. Timing and scope both matter: early restructurings generate durable improvements, while late interventions yield shorter-lived boosts bounded by project horizons. Level One restructurings produce larger effects than Level Two adjustments. These patterns show that adaptation works best when it is timely and substantive. More broadly, restructuring should be viewed not as a reactive correction but as an ordinary mechanism of adaptive management -- a structured learning process that transforms performance signals into actionable design updates, reinforcing institutional flexibility and credible mid-course correction.
