Abundant research has found that men's economic status shapes their gender ideology such that men who are breadwinners are less likely to endorse egalitarian ideology than men in nontraditional arrangements. This article investigates how the association between men's breadwinning status and gender ideology is influenced by the institutional arrangements of different types of labor markets. Rigid labor markets support men's ability to be breadwinners in the long term, whereas flexible labor markets provide men with more frequent, but less permanent, experiences (...) of nontraditional arrangements. The authors anticipate that breadwinner status will have stronger effects on men's gender ideology in rigid labor markets because men can expect less fluctuation in their employment situations in those contexts. Results from a multilevel analysis of 27 countries indeed demonstrate that individual men's economic dependency on their partners influences men's gender egalitarian ideology more strongly in rigid labor markets than in flexible markets.
