Microeconomics Chp 7
| Term | Definition |
|---|---|
| Law of diminishing marginal utility (satisfaction) | As consumption of a good or service increases, the additional (marginal) satisfaction gained from consuming each additional unit decreases Ex: The satisfaction of eating any Oreo after the first decreases with each Oreo |
| Utility | the satisfaction one gets from consuming a good or service. -Not the same as usefulness -Subjective -Difficult to quantify |
| Total utility | the total amount of satisfaction. |
| Marginal utility | the extra satisfaction from an additional unit of the good MU= △TU/△Q Ex: Consider a family that has seven slices of bread; the marginal utility of receiving an eighth slice is significant, as it reduces their hunger further. |
| Theory of Consumer Behavior (2) | Rational behavior -Preferences Budget constraint -Prices |
| Utility Maximizing Rule | To maximize satisfaction, consumers should allocate income so that the last dollar spent on each product yields the same marginal utility |
| Consumer Equilibrium | when the price of a good equals the marginal utility (MU) derived from it, leading to a balance where total satisfaction is at its highest |
| Basic determinants of an individual’s demand: | -Preferences or tastes -Income -Prices of other goods |
| Income effect: | the change in demand for a good or service resulting from a change in a consumers' real income Ex: your income increased, allowing you to buy more of your favorite candy now that you have more purchasing power |
| Substitution effect: | occurs when consumers switch from one product to another due to changes in relative prices, leading to shifts in demand. |
| Excise taxes: | Taxes that target particular products -can change consumer behavior or upset consumer equilibrium Ex: A 3 pack-per-day smoker might cut down to one pack after excise taxes |
