The value in parentheses in the initial column, next to the labels, is the number of fixed effects included in each line. See Appendix 1 for the definitions of the variables and fixed effects. All regressions are OLS regressions. Standard errors are in parentheses. Significance: *p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001.
