摘要

This paper evaluates a large urban public works program randomly rolled out across neighborhoods of Addis Ababa , Ethiopia. We find the program increased public employment and reduced private labor supply among beneficiaries and improved local amenities in treated locations. We then combine a spatial equilibrium model and unique commuting data to estimate the spillover effects of the program on private sector wages across neighborhoods: under full program rollout , wages increased by 18.6 percent. Using our model , we show that welfare gains to the poor are six times larger when we include the indirect effects on private wages and local amenities.
