Kenneth George "Ken" Binmore, CBE, FBA (born 27 September 1940) is an English mathematician, economist, and game theorist, a Professor Emeritus of Economics at University College London (UCL)[1] and a Visiting Emeritus Professor of Economics at the University of Bristol.

This has brought him into conflict with some proponents of behavioural economics who emphasise the importance of other-regarding or social preferences, and argue that their findings threaten traditional game theory.

Binmore's work in political and moral philosophy began in the 1980s when he first applied bargaining theory to John Rawls' original position.

Hume inspired Binmore to contribute to a naturalistic science of morals that seeks foundations for Rawlsian ideas about fairness norms in biological and social evolution.

While Director of ELSE, Binmore became widely known as the "poker-playing economic theorist", who netted the British government £22 billion when he led the team that designed the third-generation (3G) telecommunications auction in 2000.

He was appointed a CBE in the New Year's Honours List 2001 for contributions to game theory and to designing the UK 3G telecommunications auctions.
