sounds more like endoegeneity (Y affecting X) than selection on Y (which
involves choosing different observations as a function of Y|X).
perhaps he can argue his way out of endogeneity if by 'democraticness' of
the international organization he is not refering to the democraticness of
the countries who are members.

All,
I trust your papers are coming along nicely. Just one question.
We are dealing with an article about the impact of international organizations
on democratization. The author argues that as a state joins international
organizations, it is more likely to democratize itself. His explanatory
variable is the international organization score, which is the score of the
most *democratic* international organization, of which a state is a member.
Now my question is by taking the score of the most democratic international
organization, isn't the author selecting on DV? Of course, the country that
joins a democratic international organization is more likely to democratize
itself than one that does not join. And the more democratic the organization
is, the more likely the country is to democratize.
Any comments? My thought is that he is selecting on DV.
