The author studies three aspects of human live valuation and its relation with and cost benefit analysis in administrative regulation. More precisely, the author addresses the problem of valuation of a statistical human life and its relation with cost benefit analysis in mortality risk reduction policies. First, studies the debate about Valuation of a Statistical Human Life (VSL) and Cost-Benefit Analysis (CBA) in mortality risks regulation; second, addresses the problem of discount rates in the calculus of VSL and the problem of (dis)counting value of future human lives, and finishes testing if culture (represented as a set of values) has an incidence in risk preferences and, therefore, in willingness to pay for life.
