Unilateral trade liberalisation predicts faster manufacturing productivity growth through import competition and export discipline.

PARTIALengine/runs/trade_openness_manufacturing_productivity_spillover

PARTIAL — coef=-5.758e-16, p=7.77e-06; effect magnitude effectively zero

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=-5.758e-16, p=7.77e-06; effect magnitude effectively zero

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 2023, using a panel fe design, with fixed effects for country and year.

  • Treatment var

  • Outcome var
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.
