Agents forming adaptive expectations generally make systematic mistakes. This characterization has fostered the rejection of adaptive expectations in macroeconomics. Experimental evidence, however, shows that in complex environments human subjects frequently rely on adaptive heuristics –...

Such subjective beliefs violate the … rational expectations paradigm and are also not in line with the predictions of the rational Bayesian learning paradigm. We …
