Hypotheses·growth·capacity_transport_infrastructure_market_access_productivity

Transport infrastructure raises regional productivity and employment where procurement quality and maintenance capacity are high; low-capacity buildouts show weaker productivity gains and higher debt per road-km improvement.

PARTIALengine/runs/capacity_transport_infrastructure_market_access_productivity

PARTIAL — coef=+1.382e-06, p=0.422 (above α=0.1); direction inconclusive

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

policy briefMixed or noisy

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 evidence is suggestive but not decisive. coef=+1.382e-06, p=0.422 (above α=0.1); direction inconclusive

why it matters

Growth claims can look convincing in single success stories. This test asks whether the pattern survives a broader comparison.

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
  • Rail passenger km
What we checked
  • Real income pc growth
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.

Transport infrastructure raises regional productivity and employment where procurement quality and maintenance capacity are high; low-capacity buildouts show weaker productivity gains and higher debt per road-km improvement.

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.
