  1. Note: Panel A reports the share of leave spells where the birth month imputed from the start of the leave spell in the IABS coincides with that in the Pension Register, by birth month in the IABS data. The last row reports the p-value for the hypothesis that the birth month dummies in a linear probability model are jointly equal to zero. Panel B reports results from linear probability models where the dependent variable is equal to 1 if the birth month in the IABS is the same as that in the Pension Register. The findings are based on Sample C. Robust standard errors in parentheses.
