Steve,
Thanks for your suggestion. I have included country dummies by hand into my
(linear) cross-section model. The problem I've got is that some of those
country dummies get dropped, and I cannot have control over the dummies that
get dropped.
Any further suggestions will be more than welcomed!
Thanks,
Andrea

> You can just create the fixed effects by hand (a dummy variable for each
pair of countries) and include them in your model (assuming it is a linear
model).
