Japanese Labour Markets & Demographic Transition

Key Readings & Authorities

• FLASH textbook – Labour-market chapter.
• East Asia Forum short pieces (≈800–1,000 words) on labour shortages, wage stagnation, seniority rules, womenomics.
• Mary Brinton (Harvard, sociology) – gender/equality in Japanese households & firms.
• Claudia Goldin – ageing & labour-market participation.
• Nagase Nobuko – leading Japanese gender-labour scholar (East Asia Forum essays).
• Yashiro – policy-maker/academic on demographic economics.

Demographic Challenge: Shrinking & Ageing

• Population peaked 2008 (≈ $126\text{ million}$ ); working-age (15–64) peaked 1998 and has declined since.
• Only cohorts growing are 65 + and 80 +.
• Dependency-ratio definition:
$\text{DR}=\dfrac{\text{Pop}(0!\text{--}14)+\text{Pop}(65+)}{\text{Pop}(15!\text{--}64)}$
– Currently ≈ $0.64$ ; projected to exceed $1$ after 2050 without reforms.
• Public debt ≈ $260\%$ of GDP (Greece crisis was $\sim 110!\text{–}130\%$ ). High GDP growth needed to stabilise ratio.
• Labour-productivity per working-age person respectable (2010s > Germany) but absolute GDP slipping (Germany overtook JP 2023 with only 83 m people vs 122 m).

Fertility Dynamics

• Replacement fertility = $2.1$ children per woman.
• Japan: $1.3!\text{–}1.4$ (higher than SK $0.8$ , CN <1.2). • Historic dip 1966 – Fire-Horse superstition (Hinoe-Uma): fewer births to avoid girls “burning houses / killing husbands.” Illustrates cultural shocks on TFR. • Policy forecasts have repeatedly over-predicted rebounds (1976, 1986, 1997, 2006). • Slight uptick post-2005 due to: – expansion of childcare places; – financial incentives (baby bonus, free high-school tuition); – gradual shifts in gender norms. • Empirical regularity (Goldin, Brinton): higher gender equality in household labour ⇒ higher fertility among rich countries (Scandinavia > Japan/Italy).

Immigration as a Valve

• 2024: ≈3 m foreign residents; ≈2 m in workforce.
• Cabinet Office (2014): to stabilise pop. at 100 m needs net +200 k migrants/yr (AUS equivalent = +1 m/yr).
• Current pathways: 5-yr “specified skills” visas (≈350 k target) ≠ permanent migration; tiny refugee intake.
• Large societal resistance; tourism surge ≠ settlement acceptance.

Raising Retirement Age

• Retirement already shifted 60 → 65; debate on 70–75.
• Government scenario (2014): if LFP of women & elderly rises, labour force falls only from 66 m (2014) to 64 m (2030) instead of to 57 m.
• Post-retirement re-hiring common: same employer, lower pay, casual status.

Ageing & Entrepreneurship

• Older societies show lower start-up rates → fewer disruptive innovations.
• Corporate hierarchies clog promotion: senior posts held until mandatory retirement.

Labour-Market Institutions

1. Lifetime Employment (Shūshin-koyō)

• Enter firm straight from school/university, stay until retirement.
• Company assigns any location/department; refusal culturally taboo.
• Firing permanent staff legally & socially difficult; firms exit via bankruptcy/ spin-offs rather than lay-offs.

2. Seniority-Based Wages (Nenko-joretsu)

• Low early-career pay; steep earnings slope later (cf. US flatter profile).
• Enables heavy firm-specific training—workers repay cost by staying.
• Reform contentious: older cohorts oppose flattening after decades of “deferred” wages.

3. Bonuses

• Twice-yearly (summer & winter); 3–5 months of base salary common.
• Acts as profit-sharing & cyclical buffer (cut bonuses before head-count).
• 2023: trading houses Mitsui & Mitsubishi each paid bonuses > average annual base pay.

4. Flexible Job Rotation

• Tool to smooth business-cycle shocks within lifetime-employment model (e.g.
bank teller displaced by ATM moved to marketing).

Non-Regular Employment & Dualism

• Non-regular categories: part-time, temp, dispatched, fixed-term.
• Share of workforce ≈ $\tfrac{20}{56} \approx 37\%$ (≈2019).
• Provides external flexibility firms lack for regular staff; concentrates women & youth in precarious, low-training roles.

Gender & Work

Participation

• Classic “M-curve”: labour-force participation dips in 30s (child-rearing) then rises.
• Curve is flattening: female LFP 2013 ≈ 65 %, 2023 ≈ 76 % (> OECD avg, > US).
• Inflection linked to Abenomics “Womenomics” rhetoric (2013-) and childcare expansion.

Wage & Promotion Gaps

• Overall gender wage gap among permanent workers ≈25–30 %; wider when non-regular included (JP & KR largest in OECD).
• Managerial shares (2022):
– Lower Mgmt 21 % women.
– Middle+Senior 11.5 %.
– Senior alone 8.5 %.
• Paradox: Japanese women are among world’s most highly educated; huge opportunity cost.

Institutional Barriers

• Spousal-deduction cliff: secondary earner gets tax & social-insurance subsidies if annual income ≤ $1,000,000\;¥$ (≈US$11 k).
– Creates sharp bunching just below threshold (Kitao, 2020).
– Opposition parties propose abolition; government opted for cheaper free-tuition measure instead (2021).
• Child-care shortages; long work-hours culture; paternity leave rare (firms earned “family-friendly” sticker if even 1 man took leave!).
• Salaryman ethos (Rising Wasabi satire: husband presents Meishi to own daughter during Golden Week).

Education-Finance Side-Note

• JP ‘scholarships’ = interest-bearing JASSO loans; default → debt collectors to student & relatives, credit blacklisting.
• Bruce Chapman (ANU) proposed HECS-style income-contingent loans (revenue-neutral, marriage-market-neutral) – still pending.

Policy Toolbox & Binding Constraints

Raise retirement age (65 → 70 → 75).
Increase female LFP: abolish ¥1 m cliff, expand childcare, reduce overtime, normalise paternity leave, performance-based HR systems.
Mobilise elderly: flexible hours, health-care tech (elder-care robotics).
Selective immigration: skilled & care-sector visas, path to permanence.
Reform labour dualism: ease dismissal rules for regulars while upgrading rights/training of non-regulars.
Maintain productivity growth: digitalisation, AI, corporate governance reform to spur entrepreneurship.

Macro-Economic & Global Context

• Labour scarcity may raise wages/productivity ("end of salaryman era"), nudging economy out of stagnation (East Asia Forum, 2023 editorial).
• Japan is global front-runner in demographic transition—policy success/failure will be template for China, SK, EU.
• Worldwide fertility now near replacement in 6 / 7 of humanity; only Sub-Saharan Africa (1 bn→5 bn by 2100) will supply abundant labour.
• If Africa develops (fertility falls), labour globally becomes scarce & valuable; poverty then stems more from inherited wealth disparities than from low wages.
