Note: Standard errors are clustered at the “concession” region level with 25 clusters for “all groups” and 17 clusters in the subgroups.
↵a Matched samples are based on nearest-neighbor propensity score matching with Mahalanobis distance metric with calipers set to 0.25 standard deviations taken from the sample with 300,000 observations. Results based on a linear probability model where the dependent variable equals 1 if pixel is deforested, 0 otherwise.
↵* Significant at 10%;
↵** significant at 5%;
