Quasi-Transitive and Suzumura Consistent Relations

A classical argument of de Finetti holds that Rationality implies Subjective Expected Utility (SEU). In contrast, the Knightian distinction between Risk and Ambiguity suggests that a rational decision maker would obey the ...
Analogy in Decision-Making
