Effects of Forest Certifcation

Note: All covariates include variables listed in Appendix Tables A2 and A3, respectively, and county and year fxed effects. The sample includes 21 counties and 13 years. Reported standard errors are robust (White 1980) for OLS, and Abadie and Imbens (2006, 2011) for covariate matching. ATT, average treatment effect on the treated; CVM, covariate matching; FE, fxed effects; IHS, inverse hyperbolic sine transformation; OLS, ordinary least squares.

p < 0.1; ** p < 0.05; *** p < 0.01.
