Breaking down the question
The instruction is to write a "short essay", which signals a coherent, well-structured discussion rather than a list of points. The subject is the Latin American perspective on "dependency" — a body of thought that emerged in the mid-twentieth century as a critique of the dominant modernisation theory of development. The examiner expects you to explain what dependency means, why it arose in Latin America, its central arguments and thinkers, and its strengths and criticisms.
Dependency theory holds that the underdevelopment of poorer nations is not an original or natural condition but a product of their subordinate integration into a world capitalist economy dominated by the rich nations. The word "dependency" itself denotes a relationship in which the economies of some countries are conditioned by the development and expansion of others. Naming the Latin American economists and sociologists who built the framework is essential.
How to approach it
Open with the intellectual context — dependency theory as a Latin American reaction against modernisation theory and against the failure of development in the region. Then set out the core concepts: Prebisch and the structuralist critique of unequal exchange; Frank's metropolis-satellite chains and the "development of underdevelopment"; dos Santos's definition; and Cardoso's more nuanced idea of associated-dependent development.
Devote a section to evaluation — the theory's insight into global inequality and its limitations, including its pessimism and the counter-example of East Asian industrialisation. Keep the essay flowing and analytical. The place of dependency within the wider debate on how societies develop is set out in our notes on theories of social change.
Model answer
Dependency theory is among the most influential contributions of Latin American social science, and it arose as a direct challenge to the modernisation theory that dominated development thinking in the mid-twentieth century. Modernisation theory held that poor nations were simply at an early stage of a universal path and would develop by emulating the West and integrating into the world economy. The Latin American experience seemed to contradict this: despite long integration into global trade, the region remained poor and unequal. Dependency theorists argued that this was no accident but a structural consequence of how the region was tied to the world capitalist system.
The intellectual roots lie in the structuralist economics of Raul Prebisch and the United Nations Economic Commission for Latin America. Prebisch argued that the world economy was divided into an industrial "centre" and a primary-producing "periphery", and that the terms of trade moved persistently against the periphery: the prices of the raw materials it exported fell relative to the manufactured goods it imported. This "unequal exchange" meant that the gains of trade flowed to the centre, and that primary-export dependence trapped peripheral nations in stagnation. Prebisch's prescription was import-substituting industrialisation to break the pattern.
Andre Gunder Frank radicalised this analysis into a general theory. In his celebrated formulation, the "development of underdevelopment", he argued that underdevelopment was not an original state but was actively created by the same historical process that developed the rich nations. Frank pictured the world capitalist system as a chain of "metropolis-satellite" relationships running from the great world centres down through national capitals to provincial towns and rural districts, at each link extracting and channelling economic surplus upward. The satellites were impoverished precisely because their surplus was siphoned off to the metropolis. From this he drew the provocative conclusion that the satellites developed most when their ties to the metropolis were weakest, as during world wars and depressions.
Theotonio dos Santos gave the classic definition, describing dependency as a situation in which the economy of certain countries is conditioned by the development and expansion of another economy to which it is subjected, so that the dependent economies can only expand as a reflection of the dominant ones. He distinguished successive forms — colonial, financial-industrial and a new technological-industrial dependency in which multinational corporations dominated the most dynamic sectors of peripheral economies.
Fernando Henrique Cardoso, later President of Brazil, offered a more nuanced and less deterministic version. Rejecting the idea that dependency inevitably meant stagnation, he and Enzo Faletto argued for "associated-dependent development", in which some industrial growth was possible within dependency, driven by an alliance of foreign capital, the local state and a domestic bourgeoisie. This growth, however, was distorted and dependent, concentrated in enclaves, reliant on foreign technology and capital, and typically accompanied by deepening internal inequality and the exclusion of the poor. Dependency, for Cardoso, was a historical situation to be analysed concretely rather than a fixed law.
Assessed critically, the Latin American perspective on dependency has considerable strengths. It shifted the analysis of underdevelopment from internal deficiencies to external structural relations, exposing the international origins of inequality that modernisation theory ignored. It highlighted unequal exchange, the extraction of surplus and the political economy of a hierarchical world system, influencing later world-systems analysis and the wider critique of globalisation. Yet it has been sharply criticised. Its early versions were overly deterministic and pessimistic, implying that development within the world system was impossible — a claim embarrassed by the rapid industrialisation of the East Asian economies, which were deeply integrated into world capitalism yet developed rapidly. Critics also charged it with neglecting internal factors such as class structure, institutions and policy, and with offering few workable strategies beyond delinking, whose results, where tried, were mixed. Cardoso's more flexible formulation answered some of these objections by allowing for dependent development.
In conclusion, the Latin American perspective on dependency reconceived underdevelopment as a relational and historical product of the world capitalist system rather than a stage to be outgrown. Through Prebisch's unequal exchange, Frank's metropolis-satellite chains and dos Santos's definition, it delivered a powerful structural critique of global inequality, while Cardoso's associated-dependent development refined its rigidities. Though contested by the East Asian experience and by its critics' emphasis on internal factors, dependency theory remains a landmark contribution to the sociology of development and a lasting corrective to naive modernisation optimism.
Examiner's perspective
Because the question asks for a short essay, examiners reward coherent structure and argumentative flow over a bullet-point recitation. The core Latin American thinkers — Prebisch, Frank, dos Santos and Cardoso — should appear with their distinctive contributions, and the key concepts of unequal exchange, metropolis-satellite and the development of underdevelopment must be accurately explained.
The higher band belongs to answers that also evaluate the perspective — its insight into global inequality set against its determinism, and the East Asian counter-example that undermined its strong version. Noting Cardoso's associated-dependent development as an internal refinement demonstrates real depth. A crisp introduction contrasting dependency with modernisation theory, and a balanced concluding judgement, complete a first-class script.
