Pre-registration
Thailand's middle-income plateau (post-1997 and especially post-2005) is associated with weaker product-market competition, lower institutional quality, and fragmented state coordination capacity relative to East Asian peers that sustained convergence. Despite successful early export-led development, Thailand's total factor productivity growth and GDP per capita convergence slowed because of entrenched oligopolistic structures, inconsistent infrastructure investment, and regulatory capture, after controlling for initial income, human capital, trade openness, and foreign direct investment inflows.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
The hypothesis is falsified if Thailand's TFP growth post-2005 is statistically indistinguishable from Vietnam's or South Korea's at comparable income levels, or if product-market competition and institutional quality do not carry positive and significant (p < 0.10) coefficients on TFP growth in the full panel.

- Claim: Thailand's middle-income plateau (post-1997 and especially post-2005) is associated with weaker product-market competition, lower institutional quality, and fragmented state coordination capacity relative to East Asian peers that sustained convergence. Despite successful early export-led development, Thailand's total factor productivity growth and GDP per capita convergence slowed because of entrenched oligopolistic structures, inconsistent infrastructure investment, and regulatory capture, after controlling for initial income, human capital, trade openness, and foreign direct investment inflows.
- Falsification rule: The hypothesis is falsified if Thailand's TFP growth post-2005 is statistically indistinguishable from Vietnam's or South Korea's at comparable income levels, or if product-market competition and institutional quality do not carry positive and significant (p < 0.10) coefficients on TFP growth in the full panel.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Thailand's plateau is confounded by the 1997 crisis balance-sheet effects and recurring political uncertainty. Fixed effects partial out country-invariant shocks but not within-country political cycles.
