South Korea has turned Ricardo's comparative advantage inside out - that countries should specialize only in industries where they have natural advantage by creating capabilities through non-market interventions. South Korea build capabilities and comparative advantage in complex industries like shipbuilding and steel from the scratch. Steel giant POSCO best encapsulates the industrialization story of Korea and role of interventionist state in emerging economies.
Steel making was not natural to Korea. This requires huge capital investment while Korea lacked capital. Economy of scale is needed here but Korea had small domestic market and largest nearby market, Japan , was one of the finest producer of steel. Steel industry also need easy access to raw materials , Korea lacked iron-ore and was far from the main sources of supply. Besides , Koreans lacked steel making skills. And above all, Big Daddy - World Bank was hostile to such an ambitious project being taken up by an emerging economy.
Still, POSCO became one of the lowest cost steel producers in the world competing with Japan on productivity and quality and ironically even assisting USA in modernizing one of its plant. How did Korea achieve this and what role State played?
Entire funding of $3.6 billion came from state while technical know-how came from Japan. To lower input costs, govt provided discounted rate for port access, gas and electricity charges, roads water supply facilities etc. Domestic upstream industries were encouraged by govt policy of higher local component requirements. Steel manufacturing need economy of scale to lower costs. In formative years, when POSCO was not internationally competitive enough to capture steady international market, Korean govt. gave impetus to domestic shipbuilding, automobiles and heavy machinery industries - major consumers of steel. Thus, govt. not only created artificial demand for steel but also created entire ecosystem of industrialization around steel industry.
If Korean govt. were stuck with advise of Friedman or Ricardo, even today they would have been pre-occupied with textile industry. If they had fallen for Communist propaganda, they would have pampered and inefficient public sectors causing stunted growth. Instead they choose the Third way , combining State's capacity to take long term risk and national priorities with private enterprises' profit driven efficiency (POSCO was profitable from the start). Must read book to understand what is required of policy makers from emerging economies like India who have struggled with industrialization.
