Which economist's model advocates an International Trade Approach and outlines a five-stage model of development?

• A. Rostow's Model
• B. IMF
• C. World Bank
• D. Wallerstein's World System Analysis

Answer: (A)

Rostow's five-stage growth model outlines a linear path from a traditional society to an economy of high mass consumption, and it frames international trade as a key driver of that progression. The stages are traditional society, preconditions for take-off, take-off, drive to maturity, and age of high mass consumption. This approach envisions development as a sequence that can be accelerated by expanding trade, foreign investment, and openness to global markets, which push an economy from one stage to the next through increasing productivity and diversification. The other options don’t present a five-stage modernization path or emphasize trade as the central mechanism: IMF and World Bank are institutions, not developmental models; Wallerstein’s World-Systems Analysis centers on core-periphery dynamics rather than a staged, export-led growth sequence.
