Prior literature has shown that married men live longer than unmarried
men. Possible explanations are that marriage protects its incumbents
or that healthier men select themselves into marriage. Protective effe
cts, however, introduce the possibility of adverse selection. Those in
poor health have an incentive to marry In this paper we explore the r
ole of health in explaining mortality and marriage patterns, and disti
nguish protective effects from two types of selection effects. We find
adverse selection on the basis of health (unhealthy men tend to (re)m
arry sooner) and positive selection on the basis of unmeasured factors
that both promote good health and encourage marriage.
