This book explains how South Korea has uniquely transformed itself from a developing to a developed country by combining economic analysis with historical perspective, an approach badly needed but rarely taken by previous studies. The book shows that the country has done so through a tortuous process. It first explains how Korea failed earlier in history to emerge as a developing rather than a developed country after the Second World War but South Korea began to grow rapidly in the 1960s. It then explains that the country has sustained growth while undergoing recurring crises, examining three conditions for sustaining growth: macroeconomic management, structural transformation, and social conflict management. While doing so, the book interprets some important subjects differently from the previous studies; it also explains some other important subjects they have not covered sufficiently. The book finally discusses questions for the future briefly.
