Pre-registration
Among high-income economies 2000-2020, startup density (new high- growth firms per 1000 working-age population) predicts frontier prosperity — measured by real GDP per capita growth and productivity growth — more strongly than industrial-policy spending as a share of GDP. The pre-registered claim is that, in a horse-race regression, the coefficient on startup density is larger in absolute t-statistic than the coefficient on industrial- policy spending, and that countries in the top quartile of startup density show at least 0.35 percentage points higher annual productivity growth than countries in the bottom quartile.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if (a) the startup-density coefficient is not positive and significant at p<0.05, OR (b) in the horse-race the industrial-policy-spending coefficient has a larger absolute t-statistic than startup density, OR (c) the top-quartile vs bottom-quartile productivity growth gap is below 0.20 pp/year. A developmentalist / industrial-policy reading wins cleanly if (b) holds — i.e. state-directed spending outperforms private startup formation in predicting prosperity.

Panel FE horse-race: both startup density and industrial-policy spending entered simultaneously. Primary test is on absolute t-statistic comparison. Quartile comparison as robustness. Robustness: drop US (high startup density outlier); use only European sub-sample; alternative industrial-policy measure from Criscuolo et al. OECD state-aid database.

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 Entrepreneurship at a Glance and the Criscuolo-OECD high-growth firm database are preferred sources. Venture-capital data from OECD Entrepreneurship Finance database. Industrial- policy spending is the weakest-measured variable; EU State Aid Scoreboard provides the best coverage for European countries.
