There are three common features to these definitions which most dependency theorists share.
First, dependency characterizes the international system as comprised of two sets of states, variously described as dominant/dependent, center/periphery or metropolitan/satellite. The dominant states are the advanced industrial nations in the Organization of Economic Cooperation and Development (OECD). The dependent states are those states of Latin America, Asia, and Africa which have low per capita GNPs and which rely heavily on the export of a single commodity for foreign exchange earnings. Secondly, both definitions have in common the assumption that external forces are of singular importance to the economic activities within the dependent states. These external forces include multinational corporations, international commodity markets, and foreign assistance. Most dependency theorists regard international capitalism as the motive force behind dependency relationships. Andre Gunder Frank, one of the
