The sample for the experiment consists of 640 subvillages spread across three Indonesian provinces: North Sumatra, South Sulawesi, and Central Java. The prov- inces were chosen to represent a broad spectrum of Indonesia’s diverse geography and ethnic makeup. Within these three provinces, we randomly selected a total of 640 villages, stratifying the sample to consist of approximately 30 percent urban and 70 percent rural locations.8 For each village, we obtained a list of the smallest administrative unit within it (a dusun in North Sumatra and Rukun Tetangga (RT ) in South Sulawesi and Central Java), and randomly selected one of these subvil- lages for the experiment. These subvillage units are best thought of as neighbor- hoods. Each subvillage contains an average of 54 households and has an elected or appointed administrative head, whom we refer to as the subvillage head.
