The value of mortality risk reductions in Delhi, India

The authors interviewed commuters in Delhi, India, asking them to report their willingness to pay (WTP) to reduce their risk of dying in road traffic accidents in each of three scenarios that mirror the circumstances under which the majority of the road fatalities in Delhi occur. The WTP responses are internally valid, in the sense that WTP increases with the size of the risk reduction, income, and exposure to road traffic risks, as measured by length of commute and whether the respondent drives a two-wheeler. As a result, the"value of a statistical life"(VSL) is individuated-that is, it varies across groups of beneficiaries. For the most likely beneficiaries of road safety programs-the most highly exposed individuals-the VSL is about 150,000 PPP$.
