A paper delivered to a conference on international monetary relations. As well as considering power in the financial markets, Strange also makes a provisional (in light of her later work) analysis of structural power in the international political economy more generally. This analysis therefore widens out from an initial discussion of power in a specific sector (here the financial system) to examine the power of the U.S. more generally. While this includes elements of the later four dimensions - the idea of the authority/market balance and the security structure - her arguments here are not fully developed, as is evident from the rather heated discussion between her and the discussants (Robert Z. Alibar and Robert Solomon) that is reproduced following the main paper. A central part of the dispute is her refusal to separate out politics and economics, and define power in a narrow way, leading to veiled accusations of a lack of rigour, a not unfamiliar criticism.
