189. South Korea's controversial industrial policy

Episode Summary

Executive Summary: The episode examines South Korea’s 1970s Heavy Chemical and Industry (HCI) Drive and Nathan Lane’s research on whether it worked. It argues that Park Chung-hee’s directed-credit industrial policy raised investment, output, exports, productivity, and downstream spillovers in targeted sectors, while also highlighting that the broader welfare and growth effects remain unresolved.

Main Topics: South Korea’s postwar starting point (Priority: 5/5): The discussion opens with Korea’s devastation after Japanese occupation, division, and the Korean War, emphasizing how poor, agrarian, and politically unstable South Korea was in the 1950s. From import substitution to export promotion (Priority: 5/5): South Korea initially followed import substitution industrialization, but Park Chung-hee pivoted toward export-led growth, rewarding firms that could export with subsidies, tax breaks, and easier access to inputs. Nixon Doctrine and security fears (Priority: 4/5): The reduction of U.S. military commitment in Asia under Nixon created an existential shock in Seoul, pushing Park toward building a domestic industrial and military base. The Heavy Chemical and Industry Drive (Priority: 5/5): Beginning in 1973, South Korea targeted steel, non-ferrous metals, machinery, petrochemicals, electronics, and shipbuilding through cheap credit and policy support to create upstream capabilities. Evidence that the policy worked (Priority: 5/5): Lane’s research finds the HCI policy increased investment, use of capital and intermediate inputs, output, exports, productivity, and competitiveness, with spillovers to downstream industries. Policy limits, termination, and broader lessons (Priority: 4/5): The policy ended after Park’s 1979 assassination, and some effects persisted. The episode stresses that implementation details and political capacity matter, but aggregate welfare effects are still unknown.

Key Arguments: South Korea’s pre-1960s development strategy was weak import-substitution industrialization, which was also used as a vehicle for corruption. Park Chung-hee shifted the economy toward export promotion, using public targets, subsidies, tax breaks, and duty exemptions to encourage firms to export. The Nixon Doctrine created a security crisis that helped motivate South Korea to build upstream industrial capacity for eventual military self-reliance. The HCI Drive was not simply broad protectionism; it relied mainly on directed credit and free access to imported inputs rather than high output tariffs. Lane’s empirical results show that HCI firms increased investment in factories, machinery, and inputs after 1973 relative to non-HCI firms. The policy expanded output, exports, and revealed comparative advantage in heavy industries, while reducing prices relative to other industries. HCI sectors saw gains in employment and productivity, suggesting the policy improved efficiency rather than merely expanding bloated sectors. Downstream industries using HCI outputs also benefited through higher output, investment, entry, lower prices, and better export performance. Upstream input-supplying sectors saw little effect because firms could import many critical inputs from abroad. After Park’s assassination in 1979, the new regime liberalized finance and dismantled cheap directed credit, ending the core policy. Some productivity and export effects persisted after the policy ended, consistent with learning-by-doing. The study cannot yet settle the aggregate cost-benefit question or prove that HCI caused Korea’s overall growth miracle. Future industrial-policy research should focus on granular implementation details and political economy capacity, since these determine whether policies can work elsewhere.

Data Points: Korean War deaths: roughly 3 million - Estimated deaths during the Korean War Civilian massacres: thousands - Massacres committed by both sides during the Korean War U.S. troops stationed in South Korea: roughly 50,000 - American troop presence in South Korea in the late 1960s HCI target sectors: 6 sectors - Steel, non-ferrous metals, machinery, petrochemicals, electronics, and shipbuilding Wig exports share: 10% of South Korean exports - By the end of the 1960s, wigs had become a notable export category Policy period studied: 1973 to 1979 - Lane’s main empirical window for the HCI Drive under Park Chung-hee Policy end year: 1979 - Park Chung-hee was assassinated, and the policy was dismantled soon after Japanese occupation period: 1910 to 1945 - Korea was occupied by Japan before liberation at the end of World War II

Pivotal Quotes: "What I find is that this policy seemed to work, this directed credit thing, directing resources in this way to these sectors, seemed to promote investment." — Nathan Lane: Summarizing his main empirical finding on the HCI Drive "If you could export, you got goodies." — Nathan Lane: Describing Park Chung-hee’s export-promotion incentive structure "Details matter." — Chad Bown: The host’s concluding takeaway about studying industrial policy and trade policy

Implications: The episode suggests industrial policy can work when it is targeted, well-implemented, and backed by state capacity. But it also warns that success in Korea may be hard to replicate without similar political and bureaucratic institutions.
