I put in “research study problems marriage money” and got some different sites. Closer to what I was looking for.

ABC News discussed a study published in May in The Journal of Socio-Economics. It uses all that data from the government studies started in the 60s. According to ABC it shows:

“Husbands typically think the family income and wealth are greater than their wives think they are. And wives think the family debt is greater than their husbands think it is. And both husbands and wives tend to think their spouses earn less than they say they do.”

Supposedly money is becoming less of an issue. “Questions about disagreements were asked during surveys conducted in only four years, 1988, 1992, 1994 and 1996. Interestingly, fights over money have declined over that period, from 1988, when 17 percent of the couples said they often argued about money, to less than 10 percent in 1996.”

“In fact, the only years that money failed to lead the list of disagreements were 1994 and 1996. In both those years, the top dog was chores.

Once they made more money, some folks seemed to have a problem in redistributing the workload.”
