INCONCLUSIVE_DATA_PENDING — treatment 'policy_or_institution_proxy' has no within-country variation under country fixed effects

confidence cueResult card produced; verdict unclassified.

policy briefCoverage too thin

In ordinary language

Does the healthcare rule being tested improve access, cost, or outcomes for patients, or does it mainly shift pressure around the system?

plain answer

This test cannot make a firm call yet. treatment 'policy_or_institution_proxy' has no within-country variation under country fixed effects

why it matters

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

how the test works

It compares 30 country or place units from 1975 to 2023, using a panel fe design, with fixed effects for country and year.

what was measured
What changed
  • Policy or institution proxy
What we checked
  • Primary sectoral outcome
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.

Run timestamp predates this path's first git-add commit (rebase, rename, or pre-git local run). Spec hash is still the path's first-add commit — not repository HEAD — but ordering is not a clean pre-registration proof.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

SUPPORTED if the treatment coefficient has the predicted sign at p<0.10. REFUTED if the opposite sign is significant at p<0.10. Otherwise PARTIAL.

Verdict: INCONCLUSIVE_DATA_PENDING — treatment 'policy_or_institution_proxy' has no within-country variation under country fixed effects

Pre-registration

  • Claim: US-style Certificate-of-Need restrictions predict slower capacity growth and weaker health-access improvement than non-CON regimes.
