Pre-registration
Across OECD countries 1975-2020, lower product-market regulation (PMR) predicts higher long-run total-factor-productivity growth, after controlling for education attainment, capital deepening, and initial income per capita. The pre-registered claim is that a one-standard-deviation reduction in the OECD PMR composite index is associated with at least 0.3 percentage points higher annual TFP growth over the subsequent decade, in a panel with country and year fixed effects.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if (a) the panel-FE coefficient on PMR composite is not negative and significant at p<0.05 (higher PMR = lower TFP growth), OR (b) a one-SD PMR reduction corresponds to less than 0.15 pp higher annual TFP growth, OR (c) the coefficient becomes insignificant when EPL is omitted (indicating labour- market regulation is the true driver, not product-market regulation). A coordinated-market-economy / Varieties-of- Capitalism reading wins if PMR is insignificant but EPL or vocational-training variables are significant.

Panel FE with 10-year forward-differenced TFP on lagged PMR levels. Country and year FE absorb most cross-sectional variation; identification relies on within-country PMR reforms (e.g. UK 1980s, EU Single Market 1990s, Germany 2000s Hartz-adjacent product-market reforms). Robustness: use PMR sub-components separately; IV using EU-membership-induced reform pressure as instrument.

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
OECD PMR series has vintages 1998, 2003, 2008, 2013, 2018; the panel is constructed using interpolated values between vintages (piecewise-constant or linear interpolation). This is a known measurement-limitation flagged in diagnostics.
