Dear M Parameswaran
There is a "new" literature about estimating fixed-effects in nonlinear
models. Several paper of J. Hahn, but I recommend to start with
a good survey by M. Arellano and J. Hahn (2006) "Understanding
Bias in Nonlinear panel Models" (should be available on-line).

Subject: st: doubt on panel data estimation
Dear Friends,
I am a researcher at Centre for Development Studies, Kerala, India. I
have a panel data on manufacturing firms for six years. I want to
estimate a tobit model using this data. I understand that consistent
estimation of random effect tobit model requires strict exogeneity of
the regressors, which is not valid in my data set; current value of
the depended variable affects future value of regressors. Another
option is to use pooled estimation that ignore firm's specific
effects. I would be highly grateful if you could give your advice on
the choice between these two estimates or some other better methods.
Looking forward to your response,
Thanking you,
M Parameswaran
