st: IV in panel

[Vincenzo Lombardo <vl30@sussex.ac.uk>]

dear all,
i am figuring out wheter using or not IV in a random effect model for my  
panel dataset; for fixed effect there tests for overidentification and  
endogeneity, but i did not find any for the Random effect model..
have you some ideas on how to proceed?
what i did up to know is to apply standard hausman-type test on the two  
models; the RE with IV and the RE without IV and then testing which of the  
two is more efficient or consistent with hausman test..is this procedure  
correct?

cheers
