Background
- The Great Depression (1929–1939) devastated Latin American export economies that depended on raw materials (coffee, sugar, copper, nitrates, beef).
- With global demand collapsing, export revenues plummeted. Brazil’s coffee prices dropped by over 60%, and Chile’s nitrate exports fell to one-tenth of pre-1929 levels.
- Foreign investment and credit from the U.S. and Britain dried up, forcing Latin American nations to find domestic solutions.
- This crisis shifted the region from export-led growth to internal industrialization, marking the rise of Import Substitution Industrialization (ISI) and stronger state intervention in the economy.
Import Substitution Industrialization (ISI)
- Economic strategy promoting domestic industry to replace foreign imports, reducing dependence on global markets
Import Substitution Industrialization (ISI)
- Definition:
- Economic strategy aimed at replacing imported manufactured goods with domestic production to achieve self-sufficiency.
- Mechanism:
- Governments raised tariffs, subsidized local industries, and invested in infrastructure (transportation, energy, machinery).
- Impact:
- Encouraged urbanization and the growth of a new industrial working class.
- Reduced dependency on foreign imports but created new reliance on imported machinery and technology.
- Initially successful in stimulating growth but later limited by small domestic markets and lack of competitiveness.

Social and Economic Policies
- Economic Role of the State:
- Governments took a central role in economic planning and regulation.
- State-led public works programs tackled unemployment and stimulated demand (e.g., infrastructure, hydroelectric dams, transportation networks).
- Social Welfare:
- Peronist Argentina: Introduced wage increases, paid holidays, health benefits, and housing programs through the Eva Perón Foundation.
- Vargas’ Brazil:
- Implemented labor codes, minimum wage laws, and workers’ social security (the “Estado Novo” regime institutionalized social rights while limiting political freedoms).
- Nationalization:
