Absolute advantage

the mix of goods and services is just what society desires

Allocative efficiency

Assumption used in economics that all other relevant factors or variables are held constant. Models are crafted from new ideas, then tested against real world data. For example, will more government spending lead to economic growth

one's country opportunity cost is lower than another country's

Consumer surplus

the loss of consumer surplus and producer surplus caused by the inefficiency of a market that is not operating at equilibrium

Demand

-Non price factors affect demand; they are held constant for drawing a demand curve. They include: -tastes and preferences -income -prices of related goods-substitutes and complements -number of buyers -expectations about future prices

Determinants of Demand

Nonprice factors that affect it include: -production technology -costs of resources -prices of related commodities -expectations -number of sellers -taxes and subsidies

Determinants of Supply

market forces are in balance when the quantities demanded by consumers just equal the quantities supplied by producers

Equilibrium

the price at which the quantity demanded is just equal to quantity supplied

Equilibrium Price

the output that results when quantity demanded is just equal to quantity supplied

Equilibrium Quantity

the fairness of various issues and policies. Should executive salaries and bonuses be capped for publicly traded corporations

Equity

demand decreases as incomes rise

Inferior goods

holding all other relevant factors constant, as price increases, quantity demanded falls, and as price decreases, quantity demanded rises

Law of Demand

Macroeconomics

the study of decision making by individuals, businesses, and industries

Microeconomics

demand increases as incomes rise

Normal goods

once a public good is provided, no one can be excluded from consuming it

Not Exclusive

the cost of a good in terms of another that must be give up

Opportunity cost

the next best alternative; what you give up to do something or purchase something

Opportunity cost

a model that shows the combinations of two goods a society can produce a full employment. -allows us to answer: -HOW MUCH can be produced -WHAT WILL IT COST to change the production mix

PPF

can be answered by available information or facts

Positive question

market economies use prices to allocate resources, goods, and services -send signals in free market economies: -Buyers: -What to buy? -How much? -Sellers: -What to sell? -How much? -What method?

Price System

a government set maximum price that must be charged for a good or service -can lead to shortages

Price ceiling

a government set minimum price that must be charged for a good or service -lead to surpluses

Price floor

the difference between market price and the price at which firms are willing to supply it

Producer surplus

goods and services are produced at their lowest possible resource (opportunity) cost

Production efficiency

unlimited wants clash with limited resources. Everyone faces it. Economics focuses on the allocation of scarce resources

Scarcity

occurs when the price is below market equilibrium and quantity demanded exceeds quantity supplied

Shortage

goods consumers will substitute for one another. When one good rises, the demand for the other good increases, and vice versa

Substitutes

the maximum amount of a product that sellers are willing and able to provide over some period at various prices (ceteris paribus)

Supply:

occur when the price is above market equilibrium and quantity supplied exceeds quantity demanded
