🔎 Study Focus
The National Rural Employment Guarantee Scheme (NREGS) guarantees up to 100 days of paid rural work at the mandated minimum wage. The analysis evaluates whether this large-scale public-works program generated measurable aggregate economic gains at the district level in India.
📊 How the impact was measured
The design exploits the program's staggered rollout and tracks within-district changes to capture local responses over time. Key outcomes and data sources include:
🔬 Key findings
⚖️ Who benefited — and who didn't
The program raised measurable output on average, but those gains did not materialize uniformly. The absence of a detectable positive effect in poorer districts reveals an important source of heterogeneity in program impact.
💡 Why it matters
These results show that large public-works programs can generate modest aggregate gains, yet their benefits may bypass the poorest areas. The findings inform debates about the macroeconomic reach and targeting of employment guarantees and other public-works interventions.
