Document Summary
Budget constraint: the limit on consumption bundles that a consumer can afford. Consumption bundle a particular combination of goods (40 fish & 300 mangos) Qf (quantity of fish) = y (income) / pf (price of fish) Y = pm * qm + pf * qf. Slope (y/pm) / (y/pf) = pf / pm (rise over run) M = (y/pm) (pf / pm) * qf budget line. Indifference curve: shows consumption bundles that give the consumer the same level of satisfaction. If one quantity is reduced, one must be increased: higher indifference curves are preferred to lower ones. The rate at which a consumer is willing to trade one good for another. **mrs falls as you move down along an indifference curve. Perfect substitutes (extreme): two goods with straight-line indifference curves, constant mrs. Perfect complements two goods with right-angle indifference curves. Close substitutes- indifference curves for close substitutes are not very bowed.
