y1995 dropped because of collinearity.
y1996 dropped because of collinearity.
y1997 dropped because of collinearity.
Building GMM instruments..
4 instrument(s) dropped because of collinearity.
Warning: Number of instruments may be large relative to number of observations.
Suggested rule of thumb: keep number of instruments <= number of groups.
Estimating.
Performing specification tests.
