Rational Choice and Incentives

$B$ = benefits; $C$ = costs. Economics assumes individuals maximize utility (happiness or satisfaction) using all available information, even if that information is imperfect or incomplete.
Decision rule: choose the option with the highest net benefit by comparing $B$ and $C$ . A rational choice is made when the benefits outweigh the costs (B > C).
Net Benefit: This is calculated as $B - C$ . A rational actor will choose an option if its net benefit is positive. If multiple options have positive net benefits, the one with the highest $B - C$ is chosen.
Opportunity Cost: An important component of costs, this refers to the value of the next best alternative that was not chosen. For example, the opportunity cost of attending college might be the wages you could have earned if you worked instead.
Incentives: individuals respond predictably to incentives based on these cost-benefit analyses, adjusting their behavior to maximize their utility.

Incentive: something that induces an action or changes behavior.
Positive incentives (rewards): Encourage actions by offering desirable outcomes. Examples include bonuses, tax credits, good grades, or public recognition.
Negative incentives (penalties): Deter actions by imposing undesirable outcomes. Examples include fines, taxes, detention, or legal sanctions.

Benefits (B): Attaining a degree, acquiring specialized knowledge and skills, increased future earning potential, expanded social and professional networks, personal growth, and intellectual development.
Costs (C): Direct costs such as tuition fees, textbooks, supplies, and accommodation. Also, indirect costs like the opportunity cost of foregone income from not working, time commitment, and potential emotional stress.
Rational choice to attend: Occurs when the perceived total benefits (B) significantly outweigh the perceived total costs (C), meaning B > C. If the costs are greater than or equal to the benefits, a rational individual would likely choose not to attend or pursue an alternative.
