 Instrumental variables estimation using all instruments identified in Table 2. For Tobit, we report derivatives evaluated at the mean (dP/dx)), other results are IVGMM as in Table 3. Standard errors calculated allowing for clustering at the birthyearcommunity cohort level (64 clusters) are shown in parentheses below coefficient estimates which are in bold if significant at 5 % or lower; p values are in brackets
