Hello,
I want to estimate the effect of conflict exposure on women's height.
In the data, individuals are born between 1963 and 1996. The conflict started in 1996, meaning that individuals are treated at the same time but at different ages. So, I defined the treated group based on age at the beginning of the conflict in 1996. The cohort groups :
- Individuals aged 0-5 at the beginning of the conflict (born between 1991 to 1996),
-Individuals aged to 6-11 at the beginning of the conflict (born between 1985-1990)
-Individuals aged 12 to 17 at the beginning of the conflict (born between 1979-1984)
- Individuals aged 18 to 33 at the beginning of the conflict (control group –as never treated), born between 1963 to 1978.
I built a binary "exposure to the conflict" variable, namely, affected vs non-affected conflict zone, based on the village of residence. I have repeated cross-sectional data, with years of surveys in 2007 and 2013.
I was wondering if I could apply DID Callaway and Sant’Anna Approach since I do not have individuals born after the conflict in the data, and I am not sure if using the year of birth of individuals is the correct way of defining the time variable .
