Lester Lave
Lester Barnard Lave (August 5, 1939 – May 9, 2011) was an American economist who helped pioneer the field of environmental economics, notably the idea that environmental problems have quantifiable economic costs. In August 1970, over two decades before the Harvard Six Cities study definitively settled the issue, Lave and his graduate student Eugene P. Seskin published research suggesting that air pollution in American cities was causing higher death rates and attempted to calculate its economic cost.
