The concept of rationality

Thus, such an idealized form of rationality is best exemplified by computers, and not people. The good news is that economists and others who study human behavior know more than ever about how people actually choose and what shapes their choices, thanks to sophisticated experimental design and empirical analysis.

Some more than others—by adding The concept of rationality and more detail and by engaging in the conversation with evidence, we might get a story that describes reality quite remarkably well.

It is the ultimate useful model. Rational expectation theorists find that the stability of the economy is rooted in immutable individual preferences and decision rules of maximization. First, can a rational person survive in an irrational world? Law sometimes can provide an imitable standard of behavior even when monitoring costs prevent sanctions.

It has been used to analyze not only personal and household choices about traditional economic matters like consumption and savings, but also choices about education, marriage, child-bearing, migration, crime and so on, as well as business decisions about output, investment, hiring, entry, exit, etc.

He further argues that when it comes to concrete security and foreign policies, IR employment of rationality borders on "malpractice": Similarly Bartley—60logic is an attempt to provide a theory of validity, and currently accepted axioms or rules of inference may be refuted.

It is further assumed that preferences are consistent or transitive. This might seem horrific. As Pettit and Smith put it, without a trace of irony: The authoritarian approach would seriously inhibit major advances in our knowledge and would thus frustrate what it is intended to promote, which seems absurd.

Debates within economic sociology also arise as to whether or not people or organizations are "really" rational, as well as whether it makes sense to model them as such in formal models. When one proposition implies another and the implication is immediate and obviousbelieving the one requires you to believe the other…If you intend an end, and believe some act is a necessary means to it, your intention and belief normatively require you to intend the means.

All that we have to do is use it. The development of habits and conventions is consistent with saving scarce mental resources.

Unfortunately, we have no way of telling whether an explanatory theory is true.


Rationality buys us flexibility in our fables, not rigidity. For we might deny that argument is a suitable means for finding solutions to our problems, for example, if it could be shown that argument leads inevitably to paradoxes.

Some conceptions of rationality enable the calculation of determinative solutions to problems of choice when the production function or preferences and prices are known.What an Economist Means by “Rationality” Economics came to realize that the concept of rationality, with its whiff of moralizing, was in fact capable of so much more.

As we shall see, this has unlocked many nuanced ways to understand and view the concept. Herbert A. Simon and the concept of rationality: Boundaries and procedures it is argued that it is the low degree of specificity of the concept of bounded rationality one of the reasons for.

Rationality is the habit of acting by reason, which means in accordance with the facts of reality. The only alternative is acting by whim, which because reality is absolute, will result in undesired consequences. The concept of rationality provides the link between the objective of profit maximization and the production function specifying the relationship between inputs and outputs when prices are attached.

In consumption theory. Rationality plays a key role and there are several strands to this. Firstly, there is the concept of instrumentality—basically the idea that people and organisations are instrumentally rational—that is, adopt the best actions to achieve their goals.
