Hypotheses·growth·korea_post_chaebol_liberalisation_frontier_growth

South Korea's post-1997 corporate governance and financial liberalisation reforms explain a larger share of post-crisis frontier productivity convergence than the earlier heavy-and-chemical-industry (HCI) drive.

After 1997, chaebol restructuring, foreign ownership liberalisation, and banking-sector clean-ups raised total factor productivity growth and reduced resource misallocation relative to the HCI era (1973-1996), even after controlling for initial income, human capital, and global trade conditions. The claim applies to South Korea 1970-2020 in a time-series structural-break framework with cross-country comparator benchmarking.

confidence cueResult card produced; verdict unclassified.

policy briefCoverage too thin

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

This test cannot make a firm call yet. treatment '__interaction_hci_era_indicator_x_post_1997_reform_indicator' has no within-country variation under country fixed effects

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 7 country or place units from 1970 to 2020, using a panel fe design, with fixed effects for country and year.

what was measured
What changed
  • Hci era indicator
  • Post 1997 reform indicator
What we checked
  • Productivity growth
  • Income per capita convergence gap
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

3 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.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

The hypothesis is falsified if the post-1997 reform indicator does not carry a positive and statistically significant (p < 0.10) coefficient on TFP growth or convergence-gap reduction in South Korea relative to the HCI-era indicator, or if the HCI-era coefficient is larger and more significant than the post-1997 coefficient.

Strongest opposing argument

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

Notes

The 1997 crisis was exogenous in timing to some extent (Asian financial contagion), providing a plausible break point, but reform intensity was endogenous to domestic politics. Comparator countries help difference out regional trends.
