Dear All,

I am trying to access how adoption of a technology impacts ROI through Hausman Taylor model for panel data using 'xthtaylor' command. I have balanced panel of 2835 observations. The model I am currently working with have time-varying exogenous, time-varying endogenous and time-invariant exogenous variables. But I do not have time-invariant endogenous variable. Although 'xthtaylor' command works and I get the results. However, I am not sure if the estimated coefficients are still consistent or the model must contain a time-invariant endogenous variable?

Any suggestions will be deeply appreciated.

Kind regards,

Faruque.
