As I understand, it is not possible to correct for heteroscedasticity in 
xtregar (re). Has anyone written a program to takes care of both AR(1) and 
heteroscedasticity in a re model and can please share their developments 
with me? If so, I would be very grateful.

I'm not sure whether this is what Martin is looking for, but he might want to take a look 
at -xtgls- (-help xtgls-), e.g., -xtgls . . . , panels(heteroskedastic) corr(ar1 [or psar1])- to 
see if this suits his needs.
