Customs modernisation and trade-facilitation reforms predict larger reductions in import lead times and inventory costs than tariff cuts alone.

PARTIALengine/runs/trade_facilitation_customs_reform_import_time

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

When countries open more of the economy to trade and competition, do people end up with better long-run income or productivity outcomes?

plain answer

The evidence is suggestive but not decisive. coef=-5.758e-16, p=7.77e-06; effect magnitude effectively zero

why it matters

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

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.

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.
