The events of the last decade have sparked off a renewed interest in the economics and political economy of international economic interdependence. Such interdepenqence (lEI) may be loosely defined as mutual transborder transactions between economic agents located in different national states. It is implicit in lEI that the participants act in a dual capacity, that is, both as buyers and sellers of assets, goods, services or rights. Yet, except from a macro-balance-of-payments viewpoint, there is no reason why there should be a symmetrical relationship between either particular trading partners or forms of international involvement. Moreover, the effects of interdependency will depend on the relative negotiating and bargaining strengths of the participants, and on the nature of the transactions.
