Governments in Latin America raise little revenue from property taxation, despite arguments for its efficiency and equity. Adequate registry information would support consistent collection, but registries are costly to establish and maintain. Compared to tax collection, field experimental...

We set up a framework to conduct experiments for estimating spillover effects when units are grouped into mutually exclusive clusters. We improve upon existing methods by allowing for heteroskedasticity, intra-cluster correlation and cluster size heterogeneity, which are typically ignored when...

We develop a framework to conduct experiments for estimating direct and spillover effects when units are grouped into mutually exclusive clusters. Crucially, our framework accounts for heterogeneous treatment effects across clusters and heterogeneous cluster sizes, which are pervasive in...
