Positive-incentive value is the anticipated pleasure involved in the performance of a particular behavior, such as eating a particular food or drinking a particular beverage. [ 1 ] [ 2 ] It is a key element of the positive-incentive theories of hunger .
Hunger is a sensation that motivates the consumption of food. The sensation of hunger typically manifests after only a few hours without eating and is generally considered to be unpleasant. Satiety occurs between 5 and 20 minutes after eating. [1] There are several theories about how the feeling of hunger arises. [2]
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
In game theory and economics, a mechanism is called incentive-compatible (IC) [1]: 415 if every participant can achieve their own best outcome by reporting their true preferences. [ 1 ] : 225 [ 2 ] For example, there is incentive compatibility if high-risk clients are better off in identifying themselves as high-risk to insurance firms , who ...
The incentive to lie is associated with the free rider problem; if an individual reports a lower benefit, he or she will pay less taxes, but only see a marginal decrease in the public good. This informational problem shows that survey-based Lindahl taxation is not incentive compatible.
The incentive theory of motivation (incentivization) is criticized by psychologists for not being able to explain when individuals carry out behaviors despite their being little to no incentive to do so. For example, a worker who works extremely hard but for a small salary.
Incentive salience is a cognitive process that grants a "desire" or "want" attribute, which includes a motivational component to a rewarding stimulus. [1] [2] [3] [9] Reward is the attractive and motivational property of a stimulus that induces appetitive behavior – also known as approach behavior – and consummatory behavior. [3]
Examples of positive economic statements are "the unemployment rate in France is higher than that in the United States," or "an increase in government spending would lower the unemployment rate". Either of these is potentially falsifiable and may be contradicted by evidence. Positive economics as such avoids economic value judgments.
