Rationality and uncertainty

Andrew Postlewaite, David Schmeidler

Research output: Contribution to journalArticlepeer-review


Experimental psychologists and economists construct an individual or interactive decision situation in the laboratory. They find non-negligible differences between the observed behavior of participants and the theoretically implied behavior. We refer here to the expected utility theory and to strategic equilibrium in non-cooperative game theory. We comment on the question whether rationality, implies these theoretical behaviors and whether the non-negligible differences as above imply that participants in experiments are irrational. We also comment on the relation between rationality and consistency, in particular in situations of uncertainty.
