Microeconomics Flashcards
Microeconomics is
The study of how individuals, households, and firms make decisions about using limited resources.
Economic resources include:
Human resources (workers and managers) and Nonhuman resources (land, technology,minerals, oil, etc)
Microeconomists assume
that people and firms are rational and seek to maximize benefits
Trade-offs:
Choosing one thing requires giving up another
Scarcity:
The existence of limited resources
When an individual or group makes a decision
Their opportunity cost is equal to the value of the foregone options
Economic Units:
People, Households, and Firms
Marginal Benefits:
Small, incremental benefits
The law of demand:
When the price of a good increases, demand for it decreases, and vice versa.
Demand schedule:
Lists the quantity demanded of a product or service at various prices.
Market demand schedule:
A demand schedule that encompasses the entire market’s demand for a good or service at various price points.
Market demand curve:
Shows the market demand schedule
When demand curves shift left
Market demand has decreased
When demand curves shift right
Market demand has increased
Utility:
The satisfaction gained from consuming a food or service.
A consumer’s total utility can be
positive or negative
Utils:
Theoretical units used to measure satisfaction
Marginal utility:
Utility gained from consuming one more unit of a good
Substitute goods:
When the increased price of one good increases the demand for the price of another as the customer cannot afford this good and looks for a cheaper substitute
Complementary goods:
When the increase in price of one good decreases demand for another such as flashlights and their batteries
Price Elasticity of Demand (PED):
The percentage change in the quantity demanded of a good or service divided by the percentage change in the price
Used by Sellers to determine the potential loss of customers if prices are raised
PED is a measure of how demand for a good changes in relation to a change in price. If a good is elastic:
Demand changes greatly in response to price changes & PED > 1
PED is a measure of how demand for a good changes in relation to a change in price. If a good is unit elastic:
then the percentage change in quantity demanded is equal to that in price & PED = 1
PED is a measure of how demand for a good changes in relation to a change in price. If a good is inelastic:
Demand changes slightly in response to price changes & PED < 1
Cross-price elasticity:
is a measure of the effect a price change for one substitute good can have on the demand for another.
