My comments on game theory were poorly worded. Insofar as game theory is
individualist it can deal with only two people. This is of limited
interest as a base for economic theory.
But game theory also works with representative agents (as in Roy's
example). This is not methodological individualism because it posits a
set (group, class) of people with the same objective. When
institutionalists or marxists do this they are severely criticized.
