Notes: ***, **, and * Indicate significance at the levels of 1%, 5%, and 10%, respectively. The values in parentheses are standard errors robust to heteroskedasticity. Yes means the corresponding variables are controlled in the regression. Pseudo R2 is reported for nonlinear models to assess goodness of fit.
