William Vickrey
William Spencer Vickrey (21 June 1914 – 11 October 1996) was a Canadian-born professor of economics and Nobel Laureate. Vickrey was awarded the 1996 Nobel Memorial Prize in Economic Sciences with James Mirrlees for their research into the economic theory of incentives under asymmetric information. The announcement of the prize was made just three days prior to his death; his Columbia University economics department colleague C. Lowell Harriss accepted the prize posthumously on his behalf.
