Breaking down the question
The command word is "critically examine", and the specific lens is "development and dependency of various nations". For a ten-mark answer this means a concise but two-sided treatment: explain what Wallerstein's World-Systems theory says about why some nations develop while others remain dependent, and then weigh its strengths against its criticisms. The word "critically" forbids a purely descriptive account.
The essential architecture of the theory is its threefold division of the capitalist world-economy into core, periphery and semi-periphery. Getting this structure right, and linking it to unequal exchange, is the foundation on which any evaluation must stand. The reference to "various nations" invites you to show that the theory treats development and underdevelopment as relational — produced together within a single global system.
How to approach it
Given the low mark weighting, be efficient. Devote the first half to a clear exposition of the theory — the single capitalist world-economy, the core-periphery-semi-periphery structure, and the mechanism of unequal exchange that produces development at one pole and dependency at the other. Devote the second half to a balanced critique.
Locate Wallerstein within the dependency tradition alongside Frank and Cardoso to show intellectual context. Then raise the standard objections — economic determinism, neglect of internal factors, and difficulty explaining the rise of newly industrialised economies. Development and underdevelopment as a relational pair are examined in our notes on development and dependency.
Model answer
Immanuel Wallerstein's World-Systems theory analyses development and underdevelopment as products of a single, integrated capitalist world-economy rather than as separate national conditions. Extending the dependency tradition of Andre Gunder Frank, Wallerstein argued that since the sixteenth century the world has been bound into one economic system based on a global division of labour, within which nations occupy structurally unequal positions.
The theory divides the world into three zones. The core consists of advanced, industrialised nations that dominate high-skill, high-profit production and control finance and technology. The periphery comprises poorer nations that supply raw materials, cheap labour and agricultural goods, and remain economically dependent. Between them lies the semi-periphery — nations that both exploit the periphery and are exploited by the core, giving the system a measure of stability and mobility. Development and dependency are linked through unequal exchange: the core accumulates wealth by extracting surplus from the periphery, so that the prosperity of rich nations and the underdevelopment of poor ones are two sides of the same relationship. Crucially, a nation's position is not fixed; states can rise or fall between zones over time, as the semi-periphery demonstrates.
The theory has real strengths. It offers a genuinely global and historical framework, correcting the modernization theory assumption that every nation can develop by following the same internal path. By showing that underdevelopment is actively produced by a nation's location within the world economy, it explains persistent global inequality and the constraints facing poorer countries far better than accounts that blame internal backwardness alone. The semi-periphery concept adds flexibility and captures the reality of shifting positions.
Yet several criticisms limit the theory. It is often charged with economic determinism, reducing complex social and political change to the logic of a single capitalist system and neglecting culture, politics and human agency. By emphasising external structural constraints, it tends to downplay internal factors — domestic institutions, state policy and class relations — that also shape development, a point Fernando Cardoso stressed in arguing that dependent development remained possible. Most tellingly, the rise of the East Asian newly industrialised economies, which climbed from periphery towards core status through active state-led strategies, is difficult to reconcile with the theory's more pessimistic implication that peripheral nations are trapped. Critics also note that its categories are broad and hard to operationalise precisely.
On balance, Wallerstein's theory remains a powerful tool for understanding global inequality as a relational, systemic outcome rather than a national failing. Its insistence that development and dependency are produced together within one world-economy is a durable insight, even if its structural determinism and difficulty accommodating upward mobility require qualification.
Examiner's perspective
For ten marks the examiner wants a compact answer that both explains and evaluates. The strongest scripts set out the core-periphery-semi-periphery structure and the mechanism of unequal exchange clearly, then deliver a balanced critique in the space remaining. Placing Wallerstein alongside Frank and Cardoso, and citing the East Asian counter-example, demonstrates command of the debate.
The typical weakness is describing the three zones and stopping there, ignoring the command word "critically". To score in the top band, ensure the second half weighs strengths against criticisms — economic determinism, the neglect of internal factors and the challenge posed by newly industrialised economies — and close with a measured judgement on the theory's continuing value.
