Dependency Theory (Prebisch-Frank)

Dependency theory, developed by Raul Prebisch and Andre Gunder Frank, argues that global poverty is not a stage on the road to development but a structural condition actively produced by the international economic system. 'Core' nations extract raw materials and cheap labor from 'peripheral' nations while selling back expensive manufactured goods and controlling terms of trade, capital flows, and intellectual property. This creates dependency where peripheral growth benefits the core more than the periphery. Unlike modernization theory (poor nations develop by following the Western path), dependency theory argues the path itself is blocked by structural relationships. The periphery's 'underdevelopment' is not absence of development but active 'underdeveloping' by the core.

When to use it

When analyzing persistent economic inequality between nations or regions. When evaluating trade agreements, development policy, or foreign investment. When building business strategy in emerging markets and needing to understand structural constraints. When assessing whether economic relationships are mutually beneficial or extractive.

How it can help

Dependency theory provides essential structural analysis for understanding global inequality and development failure. It explains why decades of aid and free-trade agreements haven't closed the wealth gap. For business strategists, it reveals structural advantages that core-nation companies enjoy and barriers facing peripheral entrepreneurs. For policy analysts, it highlights how trade rules and financial flows systematically favor wealthy nations. Even its critics acknowledge it permanently shifted development economics from blaming poor nations' cultures to examining structural relationships.
