ABSTRACT
Several approaches focus on the international dimension of the contradiction between social classes, which, consistent with the thoughts of K. Marx, is considered as a fundamental feature of the essentially global capitalist economic system. However, they can only be accounted as systemic theories in part. For example, we have classified the economic theories of imperialism (Hobson, Bucharin, Luxemburg and Lenin) in a further chapter (see Chapter 9), among the theories stressing the relevant impact of the domestic economic structure (and internal contradictions) of the imperial countries on external relations, foreign policy and international system. Second, references to Marx thought may influence some of the authors sharing an approach focusing on the International political economy (see Chapter 3).
