This table reports the balance checks for key variables measured at baseline. Columns 1-3 report the means (and standard deviations in parenthesis) of the different experimental groups. Columns 4-6 report the p-values for T-tests of equality of means between any two of the experimental groups. Columns 7–9 report the standardized differences between any two of the experimental groups (that is the difference in means in units of standard deviation).
