Intergenerational mobility institutional determinants

Intergenerational income and educational mobility varies substantially across countries and within-country regions, with Nordic economies showing the highest rank-rank mobility and the US and UK showing lower mobility than most OECD peers (Chetty and collaborators; Corak's Great Gatsby curve). Within countries, mobility varies by metropolitan area by nearly as much as across countries (Chetty-Hendren commuting-zone data). The framework's position is that mobility is not primarily a function of redistribution intensity but of specific institutional features — school quality variance, residential segregation, housing affordability, labour-market fluidity, early-childhood environment — and that these features are largely institutional and technical rather than ideological.

Institutional features that make the model work

›School quality variance
Countries with smaller between-school quality variance (Finland, Nordic peers) show higher mobility than countries with larger variance (US, UK). Mechanism: ability-to-pay sorting into school quality transmits parental income to child outcomes.
›Residential segregation by income
Chetty-Hendren 2018 identifies residential segregation as a first-order correlate of low mobility in US commuting zones. High-segregation MSAs show low mobility even controlling for mean income and inequality.
›Housing affordability and geographic mobility
Expensive cities (SF, LA, NYC, London, SE England) price out low-income families from high-productivity labour markets, reducing the spatial mobility channel that historically delivered intergenerational gains.
›Labour market fluidity
Ease of job switching, employer-portable benefits, low entry barriers to occupations. US occupational licensing growth and non-compete spread reduce fluidity relative to historic levels; Nordic flexicurity maintains it.
›Early childhood investment
Universal or near-universal early-childhood education (Nordic systems, French école maternelle, UK Sure Start at its peak) raises mobility floors by reducing pre-school cognitive gaps.
›Two parent household stability
Empirical correlate of mobility in US commuting-zone data. Institutionally difficult to move directly, but associated with labour-market conditions affecting marriageability and family stability.

Supporting cases

chetty_hendren_moving_to_opportunity_causal

Exploiting family moves, Chetty-Hendren established causal rather than merely selection effects of neighbourhood on child outcomes. Each year in a higher-mobility commuting zone produces measurable gains in adult earnings.

nordic_high_mobility_rank_rank

Denmark, Norway, Sweden, Finland show rank-rank mobility coefficients around 0.15-0.20 vs US 0.35-0.40 (Chetty et al). Consistent with lower school-quality variance, lower residential segregation, and higher early-childhood investment.

canada_vs_us_mobility_comparison

Canada shows substantially higher mobility than the US despite similar per-capita income, labour markets, and cultural proximity. Education system design and housing markets have been identified as candidates.

uk_regional_mobility_variation

Within UK, mobility varies by local authority; London boroughs show different outcomes than ex-industrial northern cities even controlling for mean income. Consistent with institutional-conditions framework.

Disconfirming cases

redistribution_intensity_alone_insufficient

Some high-redistribution countries (Italy, France) show only moderate mobility despite large transfers. Conversely, Canada shows high mobility with lower redistribution than France. Undermines the claim that redistribution alone explains mobility differences.

mobility_declines_not_uniformly_tracking_inequality

US absolute mobility (children earning more than parents) has declined since the 1940s cohort per Chetty-Grusky- Hell-Hendren-Manduca-Narang. Relative mobility has been more stable. The two metrics behave differently and should not be conflated.

What this condition is NOT

  • A claim that redistribution is useless — but it is not the primary lever for mobility
  • A claim that mobility is the most important distributional metric — absolute income and poverty levels matter independently
  • An argument against universal early-childhood provision — it is a mobility-raising institutional feature
  • A claim that the US-Nordic mobility gap is ideological — it is largely institutional and technical
  • A claim that Chetty's rank-rank methodology is the only defensible approach — different mobility concepts trade off

Policy implications

Raising mobility requires institutional reform in education (reduce between-school quality variance), housing (increase supply in high-productivity cities to restore spatial mobility), labour markets (reduce occupational licensing and non-compete friction), and early-childhood investment. Pure tax-and-transfer redistribution, without these institutional reforms, typically does not move the mobility needle. The policy implication is that mobility is a technical and institutional problem masquerading as an ideological one.

Framework position

Intergenerational mobility is a distributional concern distinct from static inequality and requires a different policy response. The framework treats mobility as primarily determined by institutional features — school-quality variance, residential segregation, housing affordability, labour-market fluidity, early-childhood environment — rather than by the intensity of static redistribution. The cross-country pattern (Nordic high mobility, Canada high mobility, US and UK lower mobility) and the within-country pattern (Chetty's commuting-zone variation) both support an institutional-determinants reading over a pure redistribution-intensity reading. Policy response follows the institutional diagnosis: raise school quality floors, unwind residential segregation and housing-cost barriers, reduce occupational-licensing friction, invest in early-childhood environments. The US-Nordic mobility gap is mostly institutional rather than ideological, and the framework treats the institutional features as broadly transferable where political feasibility allows.
