-xtscc- (remember the dashes!) is useful for both cross-sectional dependence and heteroskedasticity, while fixed effects (it's one of the two options) allows for endogeneity

For the endogeneity problem, I tried different commands lik= e ivreg2 and xthtaylor, the last one give nice results in terms of expect= ed coeff signs and their significance, but they don't provide correct SE = for cross-sect dependence. Xtgls seems good for heteroskedasticity (= and serial correlation) but not for endogeneity.
