Note(s): Endogeneity is addressed using a control-function approach with residuals constructed from first-stage regressions. Robust standard errors clustered at the country-pair level are shown in parentheses. Symbols *, **, and *** denote statistical significance at the 10%, 5%, and 1% levels, respectively
