Across OECD country-years, disposable-income Gini is materially lower than market-income Gini after taxes and transfers.

supported

confidence cueThis is a clear pass for the claim as written. It still applies only to this sample, period, and method.

policy briefClear support

In ordinary language

Over a long period, do more market-oriented institutions translate into higher income or productivity, once the comparison looks beyond a single success story?

plain answer

The data clearly moved in the predicted direction. supported

why it matters

Distributional claims often sound morally clear but are empirically complex. This test asks whether the proposed channel explains real differences across places.

how the test works

It compares 37 country or place units from 1975 to 2024, using a descriptive design.

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

10 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 mean market-minus-disposable Gini compression is >= 0.08 and at least 90 percent of country-years are positive, with at least 300 observations and 25 countries.

Detailed result card

OECD tax-transfer systems compress market-income Gini

Verdict: supported - mean magnitude and positive-share gates both clear.

Predeclared Test

Supported if mean market-minus-disposable Gini compression is >= 0.08 and at least 90 percent of country-years are positive, with at least 300 observations and 25 countries.

Results

  • Usable panel: 712 observations, 37 countries.
  • Mean panel contrast: 0.158; positive share: 1.000.

Caveats

This is a compact local-data panel verdict. It is useful as a falsifiable first tranche, but it should not be read as a structural causal design without stronger identification.

Strongest opposing argument

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