In a broad-country panel 1990-2019, greater labour-market flexibility — measured by lower OECD EPL overall strictness, higher ease-of-hiring scores, and absence of centralized wage bargaining — predicts higher employment-to- population ratios and faster real GDP per capita growth, controlling for institutional quality, education, and trade openness. The directional claim is that a one-standard-deviation increase in flexibility predicts at least 1 percentage-point higher employment-to-population and 0.3 percentage points higher annual growth.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
SUPPORTED if β1 (flexibility) is positive and significant at p<0.10 for both employment and GDP growth. PARTIAL if positive and significant for employment but not growth. REFUTED if β1 is negative and significant at p<0.10. INFORMATIVE: excluding USA and UK should not eliminate the positive sign; if it does, the result is driven by Anglo-Saxon outliers.
formal test & threshold
test: panel_fe_labour_flexibility_employment_growth threshold: β_flexibility (employment/pop) > 0 at p<=0.10 AND β_flexibility (GDP growth) > 0 at p<=0.10 AND Ex-USA-UK robustness retains positive sign.

Two-way FE panel: employment = β0 + β1*flexibility + controls + FE. Robustness: (1) exclude USA and UK (dominant flexible cases); (2) use 5-year non-overlapping averages; (3) instrument flexibility with lagged left-party government seat share; (4) separate permanent vs temporary worker EPL; (5) subsample by income level.

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