Income Effect

The income effect is the change in an individual's demand for a good that results from a change in their purchasing power. This effect occurs because an increase in income, or a change in a good's price, alters the feasible set of purchases. For instance, a price decrease or income increase expands the set, while a price increase or income decrease shrinks it. It is important to distinguish the income effect from the substitution effect, as a change in a good's price triggers both effects simultaneously.

  • Evaluating Well-being Based on Available Choices

  • Comparing Welfare with Different Opportunity Sets

  • An individual receives a significant, unexpected inheritance, which increases their non-labor income. If this individual chooses to continue working the same number of hours and consuming the exact same bundle of goods as before the inheritance, it can be concluded that their overall well-being has not improved.

  • An employee knows there is a consistent, but random, chance they will be caught if they decide not to put in effort during any given pay period. To decide whether the risk is worth it, they need to weigh the benefit of avoiding effort against the potential cost of being fired. According to the standard economic model for this situation, how should the employee approach calculating the total potential benefit of shirking?

  • The income effect refers to the change in the quantity of a good a person chooses to buy that results from that good becoming relatively cheaper or more expensive than other goods.
