This paper assesses the impact of migrants' Home Town Associations (HTAs) locatedin France on the provision of local public goods in Mali. To this end, we computed adataset on all the HTAs that have been created by Malian migrants in France since 1981and geo-localised their interventions on the Malian territory. Thanks to Malian census data, we also built a panel dataset informing the provision of a range of public goods in all the Malian localities over the 1976-2009 period. These two sources of data allow us to implement a double di erence strategy, and to compare localities with and without an HTA, before and after its creation. We not only assess whether "having an HTA"makes a di erence in terms of local development, but also whether the intensity of thetreatment as measured by the number of HTAs intervening in each locality or the numberof year under treatment leads to di erentiated impacts. We nd that Malian HTAs havesigni cantly contributed to improve the provision of water amenities (mainly fountains), health centers and electricity connection over the 1987-2009 period. The impact is found to be stronger when the focus is on the earlier period (before 1998).
