The Limits of Transparency: Ambiguity and the History of     International Finance.  By Jacqueline Best. Ithaca, NY: Cornell     University Press, 2005. 240p. $37.50.  While social constructivism has moved into the mainstream of     international relations theory, informing scholarship in the subfields of     security studies and international organization, its application and     status in international political economy (IPE) has lagged behind. From     the articles in the highest-status political science journals to the works     on graduate syllabi across the major research universities, the study of     IPE has been dominated by a single view of markets, drawn from     neoclassical economics, premised on a narrow view of rationality, and     rooted in materialist foundations.
