Do Peacekeepers Boost Local Economies — Even After They Leave?

Why This Question Matters

Civil wars often devastate local markets and cut off livelihoods. Understanding whether UN peacekeeping missions do more than stop violence — whether they help revive local economies and sustain gains after withdrawal — matters for mission design, exit planning, and development policy in conflict-affected areas.

What the Authors Do

Deniz Cil, Hanne Fjelde, Lisa Hultman, Nils W. Metternich, and Desirée Nilsson conduct a large-N subnational study of UN peacekeeping operations to estimate how the presence and subsequent withdrawal of peacekeepers affect local economic activity in civil war countries.

How Economic Activity Is Measured

The authors combine geocoded data on peacekeeping deployments with high-resolution nighttime lights data, a widely used proxy for local economic activity and infrastructure use. This approach lets them track economic dynamics at fine spatial scales where traditional economic statistics are often unavailable.

Research Design and Methods

• The primary empirical strategy uses two-way fixed effects models to compare changes in nightlight intensity in areas with larger peacekeeping presences to other areas over time.
• The analysis incorporates matching to improve comparability between treated and control locations and reports a complementary difference-in-differences (DiD) specification to assess post-withdrawal trajectories.

Key Findings

• During deployment, a more sizable UN peacekeeping presence is associated with increases in local nightlight intensity, consistent with a boost in economic activity.
• After peacekeepers withdraw, areas that hosted missions exhibit a slow but positive trend in economic development rather than a sharp decline; this persistence is confirmed in the DiD analyses.

What This Means for Policy and Research

The results suggest that UN peacekeeping can deliver not only short-term security benefits but also measurable local economic gains that persist, albeit gradually, after forces leave. These findings point to the importance of coordinating peacekeeping, aid, and development planning around mission exit to sustain and amplify economic recovery in post-conflict settings.
