Hypotheses·labour·oecd_bargaining_extension_youth_entry_penalty

In OECD panels from 1990 to 2023, collective-bargaining systems where legal or administrative extension raises bargaining coverage far above union membership predict weaker labour-market entry for young workers and lower new-business density.

The directional claim is that a 10 percentage-point increase in the bargaining-extension gap is associated with at least a 0.7 percentage-point lower youth employment rate and lower new-business density, conditional on the business cycle, education, tax wedge, and institutional quality.

PARTIAL — coef=-0.0329, p=0.681 (above α=0.1); direction inconclusive

confidence cueThe result is useful, but not decisive. Treat it as a clue, not a settled conclusion.

policy briefMixed or noisy

In ordinary language

In plain terms, this asks whether bargaining extension gap is actually linked to better or worse youth employment rate from 1990 to 2023.

plain answer

The evidence is suggestive but not decisive. coef=-0.0329, p=0.681 (above α=0.1); direction inconclusive

why it matters

Labor-market rules often help some workers while risking job loss or slower hiring for others. This test looks for that tradeoff in observable employment or unemployment data.

how the test works

It compares 38 country or place units from 1990 to 2023, using a panel fe design, with fixed effects for country and year.

what was measured
What changed
  • Bargaining extension gap
  • Collective bargaining coverage
What we checked
  • Youth employment rate
  • New business density
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.

In OECD panels from 1990 to 2023, collective-bargaining systems where legal or administrative extension raises bargaining coverage far above union membership predict weaker labour-market entry for young workers and lower new-business density. The directional claim is that a 10 percentage-point increase in the bargaining-extension gap is associated with at least a 0.7 percentage-point lower youth employment rate and lower new-business density, conditional on the business cycle, education, tax wedge, and institutional quality.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

Refuted if the bargaining-extension gap coefficient is zero or positive for youth employment, or if the coefficient on new-business density is non-negative after controlling for GDP growth, tax wedge, education, and regulatory quality. A result concentrated only in recession years is treated as inconclusive rather than support.

Strongest opposing argument

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

Notes

Candidate Worker C spec. This directly tests whether labour-market-control tools that extend negotiated terms beyond union members reduce entry margins, without assuming the answer.
