AP Macroeconomics Unit 1

Capital

Produced goods that can be used as inputs for further production, such as factories, machinery, tools, computers and buildings

Ceteris Paribus

A Latin term meaning "all other things constant", or "nothing else changes". The assumption in economics that nothing else changes in a given situation except for the stated change.

Complements

Two goods that are used jointly in consumption.

Consumers' Surplus

The difference between the maximum price a buyer is willing and able to pay for a good or service and the price actually paid.

Marginal Analysis (Decisions at the Margin)

Decision making characterized by weighing the additional benefits of a change against the additional costs of a change with respect to current conditions.

Demand

The willingness and ability of buyers to purchase different quantities of a good at different prices during a specific time period.

Demand Schedule

The numerical tabulation of the quantity demanded of a good at different prices.

Disequilibrium

A state of either surplus of shortage in a market.

Economic System

The way in which society decides to answer key economic questions- in particular those questions that relate to production and trade.

Economics

The science of scarcity; the science of how individuals and societies make choices because of scarcity.

Entrerpreneurship

The particular talent that some people have for organizing the resources of land, labor and capitol to produce goods, seek new business opportunities, and develop new ways of doing things.

Equilibrium

The price-quantity combination from which there is no tendency for buyers or sellers to move away.

Equilibrium Price (Market Clearing Price)

The price at which quantity demanded of the good equals quantity shipped.

Equilibrium Quantity

The quantity at which the amount of the good that buyers are willing and able to buy equals the amount that sellers are willing and able to sell, and both equal the amount actually bought and sold.

Labor

The physical and mental talents people contribute to the production process.

Land

All natural resources, such as minerals, forests, water, and unimproved land.

Law of Demand

As the price of a good rises, the quantity demanded of the good falls, and as the price of a good falls, the quantity demanded of the good rises, Ceteris Paribus.

Law of Diminishing Marginal Utility

For a given time period, the marginal utility or satisfation gained by consuming equal successive units of a good will decline as the amount consumed increases, Ceteris Paribus.

Law of Increasing Opportunity Costs

As more of a good is produced, the opportunity costs of producing that good increases, Ceteris Paribus.

Law of Supply

As the price of a good rises, the quantity supplied of the good rises, and as the price of a good falls, the quantity supplied of the good falls, Ceteris Paribus.

Macroeconomics

The branch of economics that deals with human behavior and choices as they relate to highly aggregate markets or the entire economy.

Microeconomics

The branch of economics that deals with human behavior and choices as they relate to relatively small units - an individual, a firm, an industry, a single market.

Normative Economics

The study of "what should be" in economic matters.

Opportunity Costs

The most highly valued opportunity or alternative forfeited when a choice is made.

Positive Economics

The study of "what is" in economic matters.

Price Ceiling

A government-mandated maximum price above which legal trades cannot be made.

Price Floor

A government-mandated minimum price below which legal trades cannot be made.

Producers' Surplus

The difference between the price sellers receive for a good and the minimum or lowest price for which they would have sold the good.

Production Possibilities Frontier (PPF)

Represents the possible combinations of the two goods that can be produced in a certain period of time, under the conditions of a given state of technology and fully employed resources.

Productive Efficiency

The situation that exists when a firm produces its output at the lowest possible per unit cost.

Scarcity

The condition in which our wants are greater than the limited resources available to satisfy those wants.

Shortage

A condition in which quantity demanded is greater than quantity supplied. Shortages occur only at prices below equilibrium price.

Substitutes

Two goods that satisfy similar needs or desires.

Supply

The willingness and ability of sellers to produce and offer to sell different quantities of a good at different prices during a specific time period.

Supply Schedule

The numerical tabulation of the quantity supplied of a good at different prices. A supply schedule is the numerical representation of the law of supply.

Surplus

A condition in which quantity supplied is greater than quantity demanded. Surpluses occur only at prices above equilibrium price.

Comparative Advantage

The situation where a country can produce a good at lower opportunity cost than another country can.

Absolute Advantage

The ability of a party (an individual, or firm, or country) to produce a greater quantity of a good, product, or service than competitors, using the same amount of resources.

Resource

Anything that can be used to produce something else.

Trade-Offs

All options given up in order to have the the option chosen.

Efficiency

the use of resources in such a way as to maximize the output of goods and services.

Technology

The technical means for producing goods and services.

Trade

Providing good(s), service(s) or money to others and receiving good(s), service(s) or money in return.

Gains from Trade

Getting more of what is wanted/needed through trade than what could be gained if a country tried to be self-sufficient.

Specialization

A situation in which each person engages in a task that he or she is good at performing.

Quantity Demanded

The amount of a good or service that consumers are willing and able to purchase at a specific price.

Demand Curve

A graphical representation of the demand schedule. It shows the inverse relationship between quantity demanded and price.

Change in Demand

A shift of the demand curve, caused by an "outside the market" shift, which changes the quantity demanded at any/all given prices.

A Movement along the Demand Curve

A change in the quantity demanded of a good that is the result of a change in that good's price.

Normal Good

A good for which, other things equal, an increase in income leads to an increase in demand & a decrease in income leads to a decrease in demand.

Inferior Good

A good for which, other things equal, an increase in income leads to a decrease in demand & a decrease in income leads to an increase in demand.

Quantity Supplied

The actual amount of a good or service producers are willing to sell at a specific price.

Supply Curve

Shows the positive relationship between quantity supplied and price.

Change in Supply

A shift of the supply curve, caused by an "outside the market" shift, which changes the quantity supplied at any/all given prices.

A Movement along the Supply Curve

A change in the quantity supplied of a good that is the result of a change in that good's price.

Price Controls

Legal restrictions on how high or low a market price may go.

Consumer Surplus

The amount a buyer is willing to pay for a good minus the amount the buyer actually pays for it.

Production Possibilities Curve

An economic model of a simplified economy (an economy producing only 2 goods) to show trade-offs graphically.

Competitive Market

A market in which there are many buyers and sellers of the same good or service, none of whom can influence the price at which the good is sold.

Supply and Demand Model

A model of how a competitive market works. A way of showing the behaviors and interactions of buyers and sellers.
