Abstract

This paper advances an intuitive way to represent Keynes’s notion of long-term expectation. The epsilon-contamination approach is introduced and a rational and coherent decision rule is derived. The result is evidence that Ellsberg and Keynes share the notion of uncertainty and adopt the same class of decision rules
