South Korea's chaebol-reform attempts under Moon Jae-in (2017-2022, fair-trade enforcement, 2018 commercial-act amendments, minimum wage hikes) and Yoon Suk-yeol (2022-present, partial rollback) did NOT produce a measurable de-concentration of the Korean economy.

Top-30 chaebol value-added share of GDP and broader economic-concentration proxies (industry-level value-added concentration) do NOT decline meaningfully through 2023, and Korea's WGI Regulatory Quality and Control of Corruption percentile rank does not rise by more than +5 percentile points 2016 to 2022.

PARTIAL — shape=pre_post, |Δ_log|=0.0636; threshold 5.0%, observed 6.4%; claim direction ambiguous

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 minimum wages rise high relative to normal local pay, do lower-skill workers keep their jobs, or does hiring fall at the margin?

plain answer

The evidence is suggestive but not decisive. shape=pre_post, |Δ_log|=0.0636; threshold 5.0%, observed 6.4%; claim direction ambiguous

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 2010 to 2024, using a descriptive design.

what was measured
What changed
  • Post 2017 reform indicator
What we checked
  • Wgi regulatory quality
  • Wgi control of corruption
  • Wgi government effectiveness
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.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

PRIMARY (dispositive): SUPPORTED if WGI Regulatory Quality percentile rank for KOR rises by AT MOST +5 percentile points from 2016 to 2022 (no meaningful regulatory-quality improvement). REFUTED if KOR WGI Regulatory Quality rises by more than +10 percentile points (clear reform success). INFORMATIVE (not gating): WGI Control of Corruption percentile same-window change.

Within-Korea pre-post on WGI percentile ranks. The hypothesis is a non-acceleration claim, so the threshold direction is reversed relative to typical reform-success tests.

  • Falsification rule: PRIMARY (dispositive): SUPPORTED if WGI Regulatory Quality percentile rank for KOR rises by AT MOST +5 percentile points from 2016 to 2022 (no meaningful regulatory-quality improvement). REFUTED if KOR WGI Regulatory Quality rises by more than +10 percentile points (clear reform success). INFORMATIVE (not gating): WGI Control of Corruption percentile same-window change.

Strongest opposing argument

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

Notes

Tests effort-vs-outcome on a structural reform agenda. Direct chaebol share data is hard to standardise, so the test relies on broader proxies: WGI governance quality, ratio of top-firm market cap / GDP (informative), and industry concentration via WDI manufacturing-share. Hypothesis predicts the reform attempts did NOT meaningfully shift these.
