David William Pearce OBE (11 October 1941 – 8 September 2005) was Emeritus Professor at the Department of Economics at University College London and a pioneer of environmental economics.
He is known for setting out valuation techniques for natural phenomena, arguing that the environment is "under-priced" and that the benefit of environmental services may be calculated.
His early work was on cost-benefit analysis, and the economics of pollution and natural resource depletion, before these ideas entered the mainstream of the economic sciences and policymaking.
