Sensitivity & Mechanism Analysis

Relative Income Threshold Crossing Primary Driver

Non-linear escalation in separation probability observed immediately as female relative earnings cross 50.1% household income share.

Child-Rearing Stress Interaction Factor: 1.18x

Couples with dependent children exhibit steeper hazard ratio slope increases when shifting primary breadwinner status.

Cultural Parity Neutrality Invariable Across Tiers

Effect persists across egalitarian (GEI > 0.80) and traditional cultures, indicating raw gender norms do not fully explain risk.
