“…Those insights have prompted multiple scholars to call for more research on wealth (rather than just income) inequality, not only between households, but also within couples (Frémeaux & Leturcq, 2020; Killewald et al., 2017; Maroto, 2016; Saez & Zucman, 2016). Yet, only a few studies, coming from France, Germany, and the United Kingdom, were able to address that latter question (Kapelle & Lersch, 2020; Nutz & Gritti, 2022; Grabka et al., 2015; Bessière, 2022) because, in other countries, notably Canada, assets and debts are measured exclusively at the household level in national surveys, impeding research on within‐union disparities. In those contexts, exploring how couples handle ownership of their key assets offers an opportunity to help fill the gap, for jointly owning them will equalize wealth, while more independent and individualized arrangements may facilitate the growth of inequalities between spouses over time.…”
