Theory of Consumer Behavior Flashcards
It shows the various bundles of goods that the consumer can buy for a given income
Budget Constraint
The slope of the budget constraint equals?
The relative price of the two goods (ex: pizza costs 5 times as Pepsi; therefore the opportunity cost of one pizza is 5 liters of Pepsi)
An indifference curve shows?
The various bundles of consumption that make the consumer equally happy
The rate at which the consumer is willing to substitute one good for the other
Marginal Rate of Substitution
Four Properties of Indifference Curves
- Higher indifference curves are preferred than lower ones.
- Indifference curves are downward-sloping
- Indifference curves DO NOT cross
- Indifference curves are bowed inward
The slope of an indifference curve is…
the marginal rate of substitution
When goods are easy to substitute…
Indifference curves are less bowed
When goods are hard to substitute
Indifference curves are very bowed
Two goods with straight-line indifference curves
Perfect Substitutes
Two goods with right-angle indifference curves
Perfect Compliments
The point at which the indifference curve and the budget constraint touch is the…
Optimum
It means that the Marginal Rate of Substitution equals the relative price of the two goods
Optimum
The rate at which the market is willing to trade one good for another
Relative Price
What happens at the consumer’s optimum
The consumer’s valuation of the two goods EQUALS the market’s valuation of the two goods
A good in which an increase in income raises the quantity demanded
Normal Good
