    • Aim is an earlier release/return date in exam period
  • Short papers due this week; feedback expected soon

Why Industrial Policy Matters Today

  • Trump-era tariff wars revived 1980s-style debates on “Japan Inc.” and government intervention
  • Global drivers of bigger government role:
    • Climate change & energy transition
    • Geopolitical risk, supply-chain fragility, wars (Ukraine, Middle East)
    • Pandemic shocks
  • Parallel policy offensives world-wide:
    • U.S. CHIPS & Science Act, Inflation Reduction Act (IRA)
    • EU Green Deal Industrial Plan
    • Australia’s “Future Made in Australia” strategy
    • Japan’s new Economic Security & “Mission-Oriented” industrial policy

Orthodox Economics Refresher

  • Subsidise goods with positive externalities → market under-supplies relative to social optimum
  • Tax goods with negative externalities → market over-supplies relative to social optimum
    \text{Social MC} = \text{Private MC} \pm \text{Externality}
  • Export-led catch-up model in East Asia relied on selective interventions to correct market failures while exploiting world demand
  • Growth Commission’s five pillars still relevant: credible government, macro-stability, openness, investment in people, market incentives

Institutions Behind Japan’s Catch-Up Growth

  • Central planning & “window guidance” of bank credit (“financial repression”)
  • Main-bank system, convoy regulation, capital controls (closed capital account until 1980s)
  • Broad-based education & R&D support (positive spillovers)
  • Labour-market practices (lifetime employment, seniority wages) useful in high-growth era but a drag post-1990

Government Size & Trends

  • Government consumption ratio now on par with US/UK; once low in 1980s
  • COVID bump visible but smaller than Euro-area surge
  • Public-sector employment ≈ 8\% of workforce (vs France \sim 20\%, Canada \sim21\%)
  • Despite "normal" spending ratio, Japan’s public debt is an outlier (> 260\%\,\text{GDP})

Government Failure vs Market Failure Debate

  • Open questions (no single right answer):
    • Does state have superior information?
    • How to ration subsidies? By (future) comparative advantage?
    • When & how to withdraw support (“sunset clauses”)?
  • Classic rationales beyond public goods:
    • Infant-industry protection (Krueger sceptical: capture & mis-timed exit common)
    • Monopoly/oligopoly inefficiency
    • Redistribution & inequality (market failure in sustaining social cohesion)
    • Coordination failures in big structural shifts (e.g., green transition)

“Japan Inc.” & Developmental-State Narrative

  • 1980s perception: bureaucracy (MITI) + LDP + business = Iron Triangle
  • Chalmers Johnson: MITI’s cooperative planning ≠ laissez-faire capitalism nor Soviet planning; presented as most successful model for Taiwan, Korea, Singapore
  • Zaibatsu-power vs pattern-pluralism debates: Who leads whom?

What IS Industrial Policy?

  • Government instruments that reallocate resources across sectors/firms against market outcome
    • Direct subsidies & soft loans
    • Tax credits/deductions
    • Tariffs, quotas, export restraints
    • Anti-trust exemptions, “convoy” regulation
  • Justifications
    • Externalities & spillovers (R&D, training)
    • Economies of scale & learning-by-doing
    • Strategic trade/oligopoly games, technology leadership
    • Upstream leverage for downstream clusters

Evolution of Japanese Industrial Policy

  1. 1945-mid-1950s: Reconstruction & Central Planning
    • Ex-Manchuria planners dominate; rationing & controls
  2. 1950s-1960s: Rationalisation & Growth Plans
    • Ikeda’s Income-Doubling Plan; export promotion; capital controls; MITI “picking winners”
  3. 1970s: Internationalisation & Oil-Shock Adjustment
    • Trade liberalisation (GATT/IMF); shift from oil-intensive sectors; pollution abatement
  4. 1980s: Trade Conflict Era
    • Plaza Accord 1985, \approx50\% yen appreciation → loss of export edge
    • 1986 U.S.–Japan Semiconductor Agreement & “voluntary” export restraints
  5. 1990s: Tech Policy & Partial Retreat
    • Bubble burst; focus on R&D subsidies, patent reform; Koizumi privatisation push (JP Post)
  6. 2000s-2010s: Lost Decades, Abenomics
    • Three arrows: monetary easing, fiscal stimulus, structural reform
    • Limited deregulation; six PMs in six years pre-Abe
  7. 2019-present: Economic Security & Mission Orientation
    • Export-control law, inward FDI screening, critical-tech protection
    • “New Capitalism” rhetoric (inclusive distribution) largely aspirational

Case Study: Semiconductor Subsidy Surge

  • Strategic goal: “Autonomous & Indispensable” advanced chips
  • Spend 2020-2023 ≈ US25.5 bn (≈ 0.71\% GDP) on industry support
    • Over half to two flagship projects:
    1. TSMC Kumamoto (legacy 7/6\,\text{nm}) – leverages Kyūshū cluster
    2. Rapidus Hokkaidō (domestic consortium + IBM) – target 2\,\text{nm} mass production by 2027
  • Complementary policies: 10-year subsidy certainty, university R&D funds, talent programmes (need ≈40 000 engineers)
  • Security externality: diversify away from Taiwan war risk; upstream dominance (Japan still 56 % of materials, 32 % of equipment)
  • Scale context
    • Larger (as % GDP) than U.S./EU chip packages; greater than Japan’s total 2022 ODA (US4.3 bn**)
    • Exceeds Australia’s entire “Future Made in Australia” fund (≈US15 bn)
  • Controversies / Risks
    • Global glut of legacy chips; uncertain Rapidus viability; no clear exit plan
    • Potential capture & regional pork-barrel; opportunity cost of public funds

Evidence on Effectiveness

  • Classical scepticism: 1996 Beason & Weinstein econometrics ⇒ no productivity gain; subsidies flowed to low-growth, decreasing-returns sectors
  • New causal-inference wave (Lane, Rodrik, Liu, et al.)
    • South Korea heavy-chemicals drive: positive TFP effects
    • Upstream subsidies can catalyse agglomeration & downstream growth
    • But successes mostly in developing, catch-up contexts; frontier economies face lower hit-rates
  • Key design lessons
    • Clear sunset clauses & performance benchmarks
    • Limit scope; target upstream externalities
    • Transparency & competition for funds; avoid indefinite corporate welfare

Comparative Advantage vs Security Dilemma

  • Free-trade logic: specialisation raises welfare; risk is supply disruption & carbon externalities
  • Economic-security logic: diversify, reshore, stockpile ⇒ deliberate departure from pure comparative advantage
  • Policy tension: e.g., Australia wants Chinese input for green tech and to decouple strategically

Practical Implications for Policymakers

  • Insurance frame: Governments now self-insure against climate, pandemic, geopolitical shocks; insurance premium = higher subsidies & public debt
  • Must balance:
    • Market-efficiency loss vs resilience gain
    • Short-term political wins vs long-term fiscal sustainability
  • Japan’s re-embrace shows path dependency: bureaucracies revert to tools they know (subsidies) under stress

Connections to Prior & Future Lectures

  • Ties to labour-market discussion: rigid practices hinder high-tech pivot (scarcity of engineers)
  • Finance lecture will cover fiscal constraints & zero-rate environment enabling subsidy splurge
  • Trade lecture will revisit semiconductor disputes as template for current China–U.S. frictions

Ethical, Philosophical & Real-World Dimensions

  • Fairness: should public fund R&D when private firms capture profits?
  • Inter-generational equity: semicon debt adds to already-record public liabilities
  • Global coordination: subsidy races risk "beggar-thy-neighbour" spiral; WTO disciplines weakened
  • Data transparency: citizens need metrics to judge success/failure (e.g., cost per job, TFP impact)

Key Numbers, Terms & Equations to Remember

  • Subsidy intensity: 25.5\,\text{bn USD} \approx 0.71\%\, \text{GDP}
  • Government consumption ratio Japan ≈ U.S./U.K.; public debt >260\%\,\text{GDP}
  • Positive-externality rule: subsidise when MSC
  • Plaza Accord (1985): yen appreciated ≈50\%$$, eroded export competitiveness

Take-Home Messages

  • Japan’s historical success in catch-up era does not guarantee present-day frontier successes
  • Semiconductor push embodies broader global trend toward mission-oriented, security-framed intervention, yet high fiscal & execution risk
  • New econometric literature offers nuanced support: targeted, upstream-focused, time-bound interventions can work, but context matters
  • Policymakers must navigate trade-offs between efficiency, resilience, equity and geopolitical strategy – no silver bullets, but clear design principles help.
