PARTIAL — shape=panel_summary, |Δ_log|=0.684, ratio=1.98; claim direction ambiguous

confidence cueThe result is useful, but not decisive. Treat it as a clue, not a settled conclusion.

policy briefMixed or noisy

In ordinary language

In plain terms, this asks whether nordic 1990s reform indicator is actually linked to better or worse social expenditure share income from 1985 to 2015.

plain answer

The evidence is suggestive but not decisive. shape=panel_summary, |Δ_log|=0.684, ratio=1.98; claim direction ambiguous

why it matters

This matters because welfare architecture claims should change belief only when they survive a pre-declared empirical test.

how the test works

It compares 4 country or place units from 1985 to 2015, using a descriptive design.

what was measured
What changed
  • Nordic 1990s reform indicator
What we checked
  • Social expenditure share income
  • Government debt pct income
  • Employment rate
what this does not prove

A single test is not the whole truth. It narrows the claim under a specific sample, time period, and method. Strong policy conclusions need the pattern to survive nearby tests, alternative data, and serious objections.

Who has skin in the game — schools predicting on this

1 school list this hypothesis as a test of their position. The chips below are school-level scoreboard outcomes, not a second hypothesis verdict.

hypothesis verdict vs scoreboard outcome

The banner verdict judges this hypothesis as written. The scoreboard asks whether each school's polarity-corrected prediction was right. Raw status is not a school win: SUPPORTED supports schools that needed SUPPORTED, but refutes schools that needed REFUTED.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

PRIMARY (dispositive, three-leg): the hypothesis is SUPPORTED if ALL three legs hold in at least 3 of 4 Nordic countries (SWE, NOR, DNK, FIN): (A) WELFARE-SCALE PRESERVATION — OECD SOCX public social expenditure share of GDP, peak (1985-2000) − 2005-2008 mean ≤ 3.0pp; (B) FISCAL SUSTAINABILITY — IMF GGXWDG_NGDP general government gross debt, 2005-2008 mean ≤ 1990-1995 peak + 5.0pp (i.e. debt held or fell); (C) EMPLOYMENT RECOVERY — WDI SL.UEM.TOTL.ZS unemployment rate (inverse-employment proxy), 1990-1995 peak − 2005-2008 mean ≥ 2.0pp. REFUTED if 0 of 3 legs pass in 3+ Nordics. PARTIAL if 1-2 legs pass. INFORMATIVE: per-country diagnostics + chart of debt/GDP trajectory. METHOD_VALID: requires OECD SOCX, IMF GGXWDG_NGDP and WDI SL.UEM.TOTL.ZS available for all four countries 1990-2008. If OECD SOCX is missing the verdict is INCONCLUSIVE (data gap on the primary scale-preservation outcome) — the remaining legs cannot grade the scale-preservation claim alone.

formal test & threshold
test:      nordic_1990s_three_leg_descriptive_pre_post
threshold: PRIMARY: legs (A AND B AND C) each pass in ≥3 of 4 Nordic countries (SWE/NOR/DNK/FIN), with thresholds A: SOCX peak-to-2005-2008 decline ≤ 3.0pp; B: debt drift ≤ +5.0pp; C: unemployment fall ≥ 2.0pp.

Pre/post-1990s-reform descriptive comparison across SWE/NOR/DNK/FIN over 1985-2015. Multi-metric scorecard: (a) social expenditure share decline <3pp from peak, (b) debt-to-GDP stabilised within 5pp of pre-reform peak, (c) employment rate up >2pp. Hypothesis SUPPORTED if all three preservation criteria met. Caveat: macro-cyclical recovery 1995-2007 partially explains employment + debt outcomes — flagged TODO swarm-6e for sensitivity using matched OECD donor pool.

Verdict: PARTIAL — shape=panel_summary, |Δ_log|=0.684, ratio=1.98; claim direction ambiguous

Pre-registration

  • Claim: Nordic 1990s reforms (Swedish pension 1999, Norway handlingsregel 2001, Danish flexicurity) preserved welfare-state scope while restoring fiscal sustainability, showing that welfare-state scale is not inherently unsustainable.
  • Falsification rule: PRIMARY (dispositive, three-leg): the hypothesis is SUPPORTED if ALL three legs hold in at least 3 of 4 Nordic countries (SWE, NOR, DNK, FIN): (A) WELFARE-SCALE PRESERVATION — OECD SOCX public social expenditure share of GDP, peak (1985-2000) − 2005-2008 mean ≤ 3.0pp; (B) FISCAL SUSTAINABILITY — IMF GGXWDG_NGDP general government gross debt, 2005-2008 mean ≤ 1990-1995 peak + 5.0pp (i.e. debt held or fell); (C) EMPLOYMENT RECOVERY — WDI SL.UEM.TOTL.ZS unemployment rate (inverse-employment proxy), 1990-1995 peak − 2005-2008 mean ≥ 2.0pp. REFUTED if 0 of 3 legs pass in 3+ Nordics. PARTIAL if 1-2 legs pass. INFORMATIVE: per-country diagnostics + chart of debt/GDP trajectory. METHOD_VALID: requires OECD SOCX, IMF GGXWDG_NGDP and WDI SL.UEM.TOTL.ZS available for all four countries 1990-2008. If OECD SOCX is missing the verdict is INCONCLUSIVE (data gap on the primary scale-preservation outcome) — the remaining legs cannot grade the scale-preservation claim alone.
