Skill Premia and Pre-Marital Investments in Marriage Markets

I study a decentralized marriage market with search frictions, costly pre-marital skill investments, and non-transferable utility. Despite a fully symmetric environment, asymmetric equilibria – in which one gender systematically invests more in skills than the other – can arise. The match payoffs are microfounded through a non-cooperative household game in which spouses allocate time between labor-market work and domestic production. An asymmetric equilibrium becomes available precisely as the high-skill wage rises. Further, the symmetric equilibria can be fragile while the asymmetric ones are not. Thus, rising skill premia may amplify rather than narrow gender gaps in skill acquisition.
