Past research has found that married individuals have substantially lo
wer risks of mortality than their single counterparts. This paper exam
ines how household characteristics affect spouses' risks of mortality.
A paired hazard rate model is estimated and tests are made to ascerta
in whether the estimated coefficients associated with risk factors dif
fer between husbands' and wives' equations. Cigarette smoking, risk-av
oidance behavior, poverty, and children are found to affect wives' and
husbands' mortality in similar ways. Divorce, which can be interprete
d as the termination of this shared household environment, is found to
affect spouses differently.
