This study estimates the monetary benefits to individuals from health damages avoided as a result on reductions in air pollution in the urban industrial city of Kanpur in India. A notable feature of this study is that it uses data from weekly health-diaries collected from three seasons. For measuring monetary benefits, the study considers two major components of health cost--the loss in wages due to workdays lost and the expenditure incurred on mitigating activities. The study estimates that a representative individual from Kanpur would gain Rs 165 per year if air pollution was reduced to a safe level.
