Dear Statalist,
I'm trying to estimate the effect of selfemployment experience. My analysis considers the following selection rules:
1. Wageemployed in period t and period t+5
2. Selfemployment spell between t and t+5.
This selection model thus consider 4 possible outcomes as illustrated below:
WE,t and WE,t+5
YES NO
YES 1 2
SE spell
NO 3 4
One way to estimate this selection model is to use selmlog.
However, selmlog can only estimate the wage equation (the equation of interest) for one outcome of the selection process. But I'm interested in running a wage regression for outcome 1 and 3 (see above). In other words, I'm trying to estimate a model that accounts for both sample selection and endogenous treatment (the SE spell).
Does anyone have any advice how to correct selmlog to estimate the equation of interest for two outcomes of the selection process? Any suggestions are very welcome.
Thanks,
