This paper utilizes the theory of compensating differentials for job risks from the laboreconomics literature to evaluate farmers’ differences in wage-risk tradeoffs. In thecontext of job risks, the theory predicts that farmers who place a lower value on healthstatus are willing to work for...

I find that US elderly tend to over-emphasize the importance of their genetic makeup but … underestimate the influence of their health-related choices, such as smoking, on their longevity. This finding can partially explain … effects of their genes and health-related choices on their longevity, then the average smoking rate for the age group analyzed …
