Is it Money or Marriage that Keeps People Alive?

Abstract

It is believed that the length of a person's life depends on a mixture of economic and social factors. Yet the relative importance of these is still debated. We provide evidence in this paper that marriage has a much more important (positive) effect on longevity than high income does. For men, it almost exactly offsets the large negative effect of smoking. Economics, however, plays little or no role. After controlling for health at the start of the 1990s, we find no reliable evidence that income affects the probability of death over the subsequent decade.mortality, health, income, marriage
