Note(s): Standard errors are clustered at the firm level

Additional VIF diagnostics indicate that multicollinearity is unlikely to affect the results. The mean VIF is 1.92, and the VIFs for AvgID_Total, SIZE, and FOR are 1.13, 2.15, and 1.71, respectively. The highest VIF among substantive explanatory variables is 2.15 for SIZE

*, **, and *** indicate statistical significance at the 10%, 5%, and 1% levels, respectively
