World System Approach - Dependency Theory

Dependency theory is the notion that resources flow from a "periphery" of poor and underdeveloped states to a "core" of wealthy states, enriching the latter at the expense of the former. It is a central contention of dependency theory that poor states are impoverished and rich ones enriched by the way poor states are integrated into the "world system."

The theory arose as a reaction to modernization theory, an earlier theory of development which held that all societies progress through similar stages of development, that today's underdeveloped areas are thus in a similar situation to that of today's developed areas at some time in the past, and that therefore the task in helping the underdeveloped areas out of poverty is to accelerate them along this supposed common path of development, by various means such as investment, technology transfers, and closer integration into the world market. Dependency theory rejected this view, arguing that underdeveloped countries are not merely primitive versions of developed countries, but have unique features and structures of their own; and, importantly, are in the situation of being the weaker members in a world market economy.

Background                         

Dependency Theory developed in the late 1950s under the guidance of the Director of the United Nations Economic Commission for Latin America, Raul Prebisch. Prebisch and his colleagues were troubled by the fact that economic growth in the advanced industrialized countries did not necessarily lead to growth in the poorer countries. Indeed, their studies suggested that economic activity in the richer countries often led to serious economic problems in the poorer countries. Such a possibility was not predicted by neoclassical theory, which had assumed that economic growth was beneficial to all (Pareto optimal) even if the benefits were not always equally shared. Prebisch's initial explanation for the phenomenon was very straightforward: poor countries exported primary commodities to the rich countries that then manufactured products out of those commodities and sold them back to the poorer countries. The "Value Added" by manufacturing a usable product always cost more than the primary products used to create those products. Therefore, poorer countries would never be earning enough from their export earnings to pay for their imports. Prebisch's solution was similarly straightforward:  poorer countries should embark on programs of import substitution so that they need not purchase the manufactured products from the richer countries. The poorer countries would still sell their primary products on the world market, but their foreign exchange reserves would not be used to purchase their manufactures from abroad. Three issues made this policy difficult to follow. The first is that the internal markets of the poorer countries were not large enough to support the economies of scale used by the richer countries to keep their prices low. The second issue concerned the political will of the poorer countries as to whether a transformation from being primary products producers was possible or desirable. The final issue revolved around the extent to which the poorer countries actually had control of their primary products, particularly in the area of selling those products abroad. These obstacles to the import substitution policy led others to think a little more creatively and historically at the relationship between rich and poor countries. At this point dependency theory was viewed as a possible way of explaining the persistent poverty of the poorer countries. The traditional neoclassical approach said virtually nothing on this question except to assert that the poorer countries were late in coming to solid economic practices and that as soon as they learned the techniques of modern economics, then the poverty would begin to subside. However, Marxists theorists viewed the persistent poverty as a consequence of capitalist exploitation. And a new body of thought, called the world systems approach, argued that the poverty was a direct consequence of the evolution of the international political economy into a fairly rigid division of labor which favored the rich and penalized the poor.

Dependency can be defined as an explanation of the economic development of a state in terms of the external influences--political, economic, and cultural--on national development policies (Osvaldo Sunkel, "National Development Policy and External Dependence in Latin America," The Journal of Development Studies, Vol. 6, no. 1, October 1969, p. 23). Theotonio Dos Santos emphasizes the historical dimension of the dependency relationships in his definition: [Dependency is]...an historical condition which shapes a certain structure of the world economy such that it favors some countries to the detriment of others and limits the development possibilities of the subordinate economics...a situation in which the economy of a certain group of countries is conditioned by the development and expansion of another economy, to which their own is subjected. (Theotonio Dos Santos, "The Structure of Dependence," in K.T. Fann and Donald C. Hodges, eds., Readings in U.S. Imperialism. Boston: Porter Sargent, 1971, p. 226).

Dependency theory became popular in the 1960’s as a response to research by Raul Prebisch. Prebisch found that increases in the wealth of the richer nations appeared to be at the expense of the poorer ones.

In its extreme form, dependency theory is based on a Marxist view of the world, which sees globalization in terms of the spread of market capitalism, and the exploitation of cheap labour and resources in return for the obsolete technologies of the West.  The dominant view of dependency theorists is that there is a dominant world capitalist system that relies on a division of labour between the rich 'core' countries and poor 'peripheral' countries. Over time, the core countries will exploit their dominance over an increasingly marginalized periphery.

Dependency theory advocated an inward looking approach to development and an increased role for the state in terms of imposing barriers to trade, making inward investment difficult and promoting nationalization of key industries.

Although still a popular theory in history and sociology, dependency theory has disappeared from the mainstream of economic theory since the collapse of Communism in the early 1990s. The considerable inefficiencies associated with state involvement in the economy and the growth of corruption, have been dramatically exposed in countries that have followed this view of development, most notably a small number of African economies, including Zimbabwe.
