The overall variance inflation factor (VIF) lies at 2.9 on average across all Gini regressions, and for none of the regressors does the tolerance level (1-R2) fall below 0.1. Table A.I. displays bivariate correlations for all independent variables used in the regressions. Observations are only available for 1995, 2002, 2005, 2008 and 2011.
