Note: Cross-section weights applied. ^*,^**, and ^*** denote significance at 10%, 5% and 1% respectively. Standard errors in parentheses, where OLS standard
errors are robust and the s.e. for the remaining models are bootstrapped. (N) refers to normal, (P) to percentile, and (BC) to bias corrected confidence
intervals (1000 replications).
