Stata users,
I am working on a 2SLS in which the endogenous variable is modeled using
a Tobit model (lower bound=0, upper bound=1) and the second-stage
regression also uses a Tobit model.
1st. stage
TE=f(farm charactersitics, household characteristics, country dummies)
--->Tobit model (lower bound=0, upper bound=1)
where TE takes values between 0 and 1
2nd. stage
Surplus index=f(predicted TE, farm characteristics, household
characteristics, country dummies) --> Tobit model (lower bound=-1,
upper bound=1)
where surplus index takes values between -1 and 1.
I was wondering ig there is any STATA command/code to perfrom this
analysis. Any comment or suggestion will be appreciated.
