Notes: FE confidence intervals are calculated using cluster standard error at individual level and OLS are calculated using MCS survey design. FE and OLS estimates are calculated using survey weight to account for attrition at age 17. We report 95% confidence intervals in brackets. ***, ** and * denote statistical significance at 1%, 5% and 10% levels respectively. a Indicates the lag value of the variable (see Method section for details).
