K. Ramaswamy et al., MEASURING THE DEGREE OF INTERNATIONALIZATION OF A FIRM - A COMMENT, Journal of international business studies, 27(1), 1996, pp. 167-177
Sullivan's [1994] suggestion that an index measure of the internationa
lization construct is superior to single-variable measures is critique
d on psychometric, content validity, criterion validity, reliability,
and utilitarian grounds. We argue that internationalization is more co
mplex than envisioned by this index and suggest that further refinemen
t of the construct is necessary before constructing indices.
