The interaction of marital status with education attainment may be different, however, for women and men.
But for reasons noted above we do not think it likely that such supports fatally confound this study's central finding about the interaction of marital and insurance statuses and poverty.
This study explores that notion with the same Californian cohort and advances the hypothesis that there is a 3-way interaction of marital status, health insurance and poverty on chemotherapy such that there is probably a multiplicative disadvantage of being an unmarried and inadequately insured woman living in poverty.
"Importantly, we found that when couples are engaging in a negative conflict pattern like demand or withdrawal, expressions of gratitude and appreciation can counteract or buffer the negative effects of this type of interaction on marital stability," study co-author Ted Futris, an associate professor in the College of Family and Consumer Sciences, told the journal.
A central assumption of my model is that time spent together with the mate (emotional and sexual interaction) is a normal good for agents and the amount of marital interaction negatively depends on the number of co-wives in the household.
As part of this research, for the past 15 years Levenson has also been conducting a study of long-term marriages to determine how the emotional qualities of marital interactions change over time.
Each individual values consumption, spending time together (the amount of marital interaction with the mate), number of offspring and future incomes of children.
If she is involved in polygyny, she enjoys less utility due to a lower amount of marital interaction compared to what she would enjoy in a monogamous marriage.
In this section, I argue that keeping the difference constant between utility derived from the amount of marital interaction in monogamous mating and in polygynous mating is harmless.
Similarly, Sullivan (1996), Hallberg (2003), Jenkins and Osberg (2005) and Connelly and Kimmel (2009) find evidence of this desire for spending time with one's spouse.9 The literature on marital happiness and marital stability also provides evidence for the causal affect of amount of marital interaction on marital happiness (White 1983; Hill 1988; Zuo 1992 and references therein).
