Expectation of value theory
The value-expectation theory is a psychological theory of action (cf. valence-instrumentality-expectation theory ), which can be assigned to the rational choice approach . The basic idea of this theory is:
"Preferably try yourself on actions whose consequences are not only likely, but also worth something to you at the same time! And avoid actions that are harmful or too expensive for you and / or have no effect on your well-being! "
The value expectation theory is based on six assumptions:
- Every action is a choice between alternatives .
- Every action has consequences .
- The consequences are assessed by the actor .
- The consequences occur with different degrees of probability (for the actor: expectations).
- Alternative courses of action are subjected to an evaluation (or weighting) (“WE weight”).
- The alternative course of action is always selected whose "WE weight" is the maximum.
history
The foundations were laid by the philosopher Jeremy Bentham and the statistician Daniel Bernoulli in the 18th century. While Bentham introduced the concept of utility into economic thinking, Bernoulli assumed that the alternative chosen is the one whose expected value is the highest.
