Dependent variable is percent of deforestation. Running variable is distance to indigenous territory border in meters. Coefficients are robust RDD estimates; h represents the optimal bandwidth (meters) chosen to minimize square errors. Robust standard errors are clustered at the indigenous territory level and are in parentheses. Numbers in bold represent coefficient estimates for homologated territories. **P < 0.01, *P < 0.05.
