We explore the impact of migrants' Home Town Associations (HTAs) on the provision of public goods in Mali. We combine an original dataset on all the HTAs created by Malian migrants in France from 1981 with census data on public goods in all Malian villages since 1976, and we run double-difference estimations to compare villages with and without an HTA, before and after the creation of the HTAs. We find robust evidence that the provision of schools, health centers, and, to a lesser extent, water amenities has increased significantly faster in villages targeted by an HTA between 1987 and 2009 than in control villages.
