Hi, I am using the -oaxaca- command and appear to have errors in my results. I am calculating the decomposition of log hours between two groups. I use the heckman correction option and eform to exponentiate my coefficients. The 'overall' statistic is 29 hours for group 1 and 16 hours for group 2. Descriptively, I know that these estimates are correct. Yet -oaxaca- claims the difference between these groups is less than 2 hours! Please see my code and sample output.

Code:
oaxaca lnhours  yearsed exp if sex==2 & etime>3, by(prognorm)  swap eform model1(heckman, select(yearsed age exp tchad) twostep) model2(heckman, select(yearsed age exp tchad) twostep)
