Pre-registration
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.
Falsification criterion — what would disprove this
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.

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.
