To get the results of Table C4 run the programs in this order

birth_certificates_1991.do
create_labordata.do
table_C4_create_data.do
table_C4_analysis.do
table_C4_bootstrap_se_zbarmin.do (to get correct standard errors for the Zbar_min IV)

Note that while the outcome variables are measured in 1990, the number of children and the instruments are measured in 1991.
This was done to be consistent with Angrist Evans' (1998) census data, which elicits income and labor force participation in the year prior to the census.
