Elasticity
measure of the responsiveness of one variable to changes in another variable
Own Price Elasticity
Measure of responsiveness of the quantity demanded of a good to a change in the price of that good
Factors that affect own-price elasticity
substitutes, time, percentage of one’s budget, how broadly the good is defined
Substitutes
an increase (or decrease) in the price of one good leads to an increase (decrease) in the demand for the other good
Cross-Price Elasticity
responsiveness of the demand for good to changes in the price of a related good
Consumer Preferences
determine which good will be consumed
Completeness
consumer is capable of expressing a preference for or indifference among all bundles
Monotonicity
more is better
Strict Convexity
curved line (C-shaped); demonstrates interior solutions
Transitivity
indifference curves never cross each other; consumer never makes a choice
Indifference Curves
defines the combinations of two goods that give a consumer the same level of satisfaction
Marginal Rate of Substitution
rate at which a consumer is willing to substitute one good for another good and still maintain the same level of satisfaction (slope of the budget line)
Diminishing Rate of Substitution
Marginal Rate of Substitution decreases as one moves down the indifference curve
Budget Line
bundles of goods that exhaust a consumer’s income
Consumer Equilibrium
affordable bundle that yields the greatest satisfaction to the customer
Normal Good
as income increases demand for the good will increase
Inferior Good
as income increases demand for the good will decrease
Substitution Effect
movement along a given indifference curve that results from a change in the relative price of goods
Income Effect
movement from one indifference curve to another that results from the change in real income caused by a price change
own-price elasticity formula
percentage change in quantity demanded divided by the percentage change in the price of the good
elastic demand
if the absolute value of the own price elasticity is greater than 1
inelastic demand
if the absolute value of the own price elasticity is less than 1
perfectly elastic demand
if own price elasticity is infinite in absolute value (demand curve is horizontal)
perfectly inelastic demand
if the own price elasticity is zero (demand curve is vertical)
