Bounded rationality

"The term “bounded rationality” was coined in the 1950s by Herbert A. Simon."

"Although contributions of many writers have helped the rise of behavioral economics including psychologists Kahneman and Tversky, I regard the works of George Katona and Herbert Simon instrumental in its rise. While the works of Katona and his colleagues at Michigan University led to the use of survey method in economics and its utilization in measuring the impact of consumer expectations on macroeconomic activity, the work of Simon at Carnegie Tech. (a tremendously stimulating intellectual environment for economic theorizing then) resulted in the important theoretical foundations of behavioral economics, such as the concept of bounded rationality."

"Simon’s conventionalism leads to a decision paradigm, according to which understanding problems of coordination is impossible without taking into consideration individual cognitive limits and social representations of reality."

"In a fundamental sense, Alchians theory of economic organizations is different from those of Coase or Simon. He disavows an explicit model of individual choice... and... offers a system-level explanation of organizational emergence, structure, and survival that is largely independent of decision making at the micro level... Yet it is precisely this independence of a distinct model of choice that ultimately renders it compatible with the individualistic theories of both Coase and Simon...."

"Both from these scanty data and from an examination of the postulates of the economic models it appears probable that, however adaptive the behavior of organisms in learning and choice situations, this adaptiveness falls far short of the ideal of ‘maximizing’ postulated in economic theory. Evidently, organisms adapt well enough to‘satisfice’; theydo not, in general, ‘optimize’."

"The problem can be approached initially either by inquiring into the properties of the choosing organism, or by inquiring into the environment of choice."

"If (...) we accept the proposition that both the knowledge and the computational power of the decision maker are severely limited, then we must distinguish between the real world and the actor’s perception of it and reasoning about it."

"One is forced to assume that ordinary people have the computational capabilities and statistical software of econometricians."

"Models of bounded rationality describe how a judgement or decision is reached (that is, the heuristic processes or proximal mechanisms) rather than merely the outcome of the decision, and they describe the class of environments in which these heuristics will succeed or fail."

"Two types of conventions [ in organizational settings] may be distinguished here: (a) conventional rules of behavior demonstrated in the classroom mental experience (first part of the story) and (b) conventional representation of the world revealed in the following discussions with ‘‘experienced” friends (second part)."

"… I shall assume that the concept of ‘economic man’(...) is in need of fairly drastic revision, and shall put forth some suggestions as to the direction the revision might take."

"A comparative examination of the models of adaptive behavior employed in psychology (e.g., learning theories), and of the models of rational behavior employed in economics, shows that in almost all respects the latter postulate a much greater complexity in the choice mechanisms, and a much larger capacity in the organism for obtaining information and performing computations, than do the former. Moreover, in the limited range of situations where the predictions of the two theories have been compared (...), the learning theories appear to account for the observed behavior rather better than do the theories of rational behavior."
