Tim Harford, the Undercover Economist, certainly found an interesting paper.
It's terrifically preliminary, of course, and is probably affected by the same sort of self-selection as in the previous study re: female same-sex parents, but it's worth a read. (Right?)
We analyze how sexual orientation is related to household savings using 2000 US Census data, and find that gay and lesbian couples own significantly more retirement income than heterosexuals, while cohabiting heterosexuals save more than their married counterparts. In a household savings model, we interpret this homosexual-specific differential as due to the extremely low fertility of same-sex couples, in addition to the precautionary motives driving cohabiting households to save more than married ones. Evidence from homeowners’ ratio of mortgage payments to house value exhibits the same pattern of savings differentials by sexual orientation and cohabiting status.
