I have a small TSCS data set with 7 panels (countries) and 55 observations (elections) in total.  Elections occur in different years across countries, so no observations occur in the same year.  There are no missing data.

What estimator should I use?  Xtpsce seems to require shared time values across the panels.  Creating a fake time variable may artificially erase any contemporaneous correlation.  Xtreg, i(id) re works but I don't think it allow corrections for heteroskedasticity.  Any suggestions?

Thanks!

-Ken
