Appendix C Appendix C reports the empirical results which are not documented in Section 5. I report the regression tables for the estimation results for the equations (15), (16) and (17). Note: The table reports the change in the probit response function due to a change in the indicator variable, with the rest of the covariates evaluated at the mean. The specification also includes indicators for birth orders, weight gains and medical risk factors. Robust standard errors are reported in parentheses. 76 Table C.1: Probit estimation of the first stage regression Dependent Variable: nonsmoking indicator D Tax increase in 1st trimester 0.0331 Age 41+ 0.0424 (0.0013) (0.0080) Married 0.1270 High school grad 0.0602 (0.0019) (0.0021) Hispanic 0.1214 Some college 0.1361 (0.0027) (0.0024) Black 0.1551 College grad. 0.2571 (0.0026) (0.0029) Age 2125 -0.0483 Post grad. 0.2870 (0.0025) (0.0035) Age 2630 -0.3484 Adequate care 0.0375 (0.0027) (0.0039) Age 3135 -0.0174 Intermediate care 0.0188 (0.0030) (0.0041) Age 3640 0.0078 (0.0037)
