EU countries with faster construction value-added or construction employment growth experience lower subsequent housing-cost overburden.

REFUTEDengine/runs/eurostat_construction_supply_housing_cost_relief_panel

REFUTED — coef=+0.0006784 (sign opposite claim -), p=0.0377

confidence cueThis test cuts against the claim as written or misses its pre-declared threshold.

policy briefNeeds review

In ordinary language

Does the housing rule being tested make homes easier to build, rent, or afford, or does it quietly reduce supply and push costs elsewhere?

plain answer

The data did not support the prediction. coef=+0.0006784 (sign opposite claim -), p=0.0377

why it matters

Housing policy affects rents, mobility, household budgets, and construction. The test looks for measurable effects rather than relying on slogans.

how the test works

It compares 1 country or place units from 1990 to 2024, using a panel fe design, with fixed effects for country and year.

what was measured
What changed
  • Construction value added
What we checked
  • Housing cost overburden
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

17 schools 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:

SUPPORTED if the primary treatment coefficient has the pre-registered - sign at p<=0.10 with minimum sample gates. REFUTED if the coefficient has the opposite sign at p<=0.10. Otherwise PARTIAL; missing data or failed sample gates are INCONCLUSIVE_DATA_PENDING.

Strongest opposing argument

Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
