Worker cooperative conversions (US Main Street Employee Ownership Act 2018, Italian Marcora Law 1985) preserve employment in firms that would otherwise close.

PARTIALengine/runs/worker_coop_conversion_employment_preservation

PARTIAL — ATT=+2.22e-15, p=0.717, N=66, treated_countries=2 (above α=0.10)

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 coop conversion event is actually linked to better or worse firm survival indicator from 1985 to 2023.

plain answer

The evidence is suggestive but not decisive. ATT=+2.22e-15, p=0.717, N=66, treated_countries=2 (above α=0.10)

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 2 country or place units from 1985 to 2023, using a did callaway santanna design, with fixed effects for firm and year.

what was measured
What changed
  • Coop conversion event
What we checked
  • Firm survival indicator
  • Firm employment
  • Firm real wage
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.

Who has skin in the game — schools predicting on this

8 schools list this hypothesis as a test of their position. The chips below are school-level scoreboard outcomes, not a second hypothesis verdict.

hypothesis verdict vs scoreboard outcome

The banner verdict judges this hypothesis as written. The scoreboard asks whether each school's polarity-corrected prediction was right. Raw status is not a school win: SUPPORTED supports schools that needed SUPPORTED, but refutes schools that needed REFUTED.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

The hypothesis is considered falsified if the pre-registered empirical test shows the opposite direction of the claim at conventional significance (p > 0.10), or if the primary outcome measure moves less than 10% in the claimed direction across the sample. Exact thresholds will be pinned in the variables and estimator blocks when this stub is promoted from draft.

Verdict: PARTIAL — ATT=+2.22e-15, p=0.717, N=66, treated_countries=2 (above α=0.10)

Pre-registration

  • Claim: Worker cooperative conversions (US Main Street Employee Ownership Act 2018, Italian Marcora Law 1985) preserve employment in firms that would otherwise close.
  • Falsification rule: The hypothesis is considered falsified if the pre-registered empirical test shows the opposite direction of the claim at conventional significance (p > 0.10), or if the primary outcome measure moves less than 10% in the claimed direction across the sample. Exact thresholds will be pinned in the variables and estimator blocks when this stub is promoted from draft.

Notes

Stub seeded from a market-socialist school prediction about worker-coop conversion employment preservation. Self-selection into conversion is severe; needs human review of matched-comparator strategy.
