G. L. S. Shackle

George Lennox Sharman Shackle (14 July 1903 – 3 March 1992) was an English economist. He made a practical attempt to challenge classical rational choice theory and has been characterised as a "post-Keynesian", though he is influenced as well by Austrian economics. Much of his work is associated with the Dempster–Shafer theory of evidence.
