Our results suggest that information spill-over within couples can increase participation, and that couples who purchase a home at cohabitation face other barriers such as liquidity needs and additional risk that offset the positive effects of cohabitation

2) Homeownership - those who exit the stock market are predominantly individuals who cohabit with a partner while also becoming homeowners.

We present evidence on two key drivers:
1) Information spill-over - Those who enter the stock market are predominantly individuals who cohabit with a partner with stock market experience.

We find that cohabitation increases the propensity to enter the stock market and the propensity to exit the stock market. This suggests that individuals' financial decisions can be affected by their partner already prior to marriage.

It is a well-known puzzle that few people participate in the stock market, but barriers to the individual’s participation decision likely change when they cohabit with a partner. Isabel Skak Olufsen and I study financial decisions around cohabitation using rich admin data from Denmark.

In this paper, we show that cohabitation increases both entry into and exit from the stock market - suggesting that financial decisions are influenced by partners even before marriage.
