Post-1990 (and especially post-EU-accession 2004/2007) outmigration from Eastern Europe (POL, ROU, BGR, LTU, LVA, EST, HUN, SVK) has produced upward pressure on real wages at origin via labour-supply contraction. The hypothesis predicts a positive association between cumulative net out-migrant share and real-wage growth at origin over 2004-2023, conditional on productivity growth.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
SUPPORTED if cumulative outmigrant share has positive coefficient on real-wage growth at p<0.05 controlling for labour productivity, with magnitude >= 0.2pp wage growth per pp of cumulative outmigrant share. REFUTED if coefficient insignificant, wrong-signed, or absorbed by productivity control.

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