4 Factors = Land, Labor, Capital, & Entrepreneurship

Land

Natural resources and features used as an input.

Ex: oil, water, wood, air, metals, etc

Labor

Human effort used in the production of goods and services.

Ex: Literally any job

Capital

The stuff needed to make the end product, falls into Financial (money), Physical (tangible), and Human (education) Capital.

Entrepreneurship

The ability to combine resources to satisfy society’s needs, wants, and desires.

Ex: Levi Strauss capitalizing on denim pants production during the Gold Rush.

Business Cycle

The natural rise and fall of economic growth over time.

Depression

A prolonged and severe downturn in economic activity.

Ex: Great Depression

Recession

Periods of economic decline typically indicated by two consecutive quarters of negative GDP growth.

Ex: 2008 Housing Bubble

Expansions

Periods of increasing economic activity and growth in GDP.

Ex: US economy “booming” after WW2.

Employment

Being actively engaged with a paid job in the workforce.

Unemployment

Output

The total amount of goods and services produced in an economy.

Aggregate Output

The total output of goods and services produced in an economy over a specific period.

Ex: GDP of a nation.

Inflation

The rate at which the general level of prices for goods and services is rising.

Deflation

The decline in the general price level of goods and services.

Price Stability

When the prices in an economy do not change significantly over time.

Economic Growth

The increase in the economy's capacity to produce goods and services over time.

Ex: An GDP growth of 2% annually indicates growth.

Model

An abstraction of reality used to explain and predict economic phenomena.

Other Things Equal Assumption

Assuming that all other variables remain constant when analyzing the effect of a singular one.

Trade-Off

Giving up one benefit to have another.

Ex: “Guns” vs. “Butter”

Production Possibilities Curve

Graph that shows the production of two goods that can be produced with available resources and technology.

Efficient

When resources are utilized correctly, minimizing waste and maximizing output.

Technology

Tools, machines, knowledge all enhance productivity and aid services.

Ex: The assembly line at a car plant has revolutionized how fast cars can be made.

Trade

Exchange of goods or services between individuals or nations.

Gains from Trade

Benefits obtained from trading goods and services; producing beyond one’s PPC results in this from trading.

Specialization

Focusing on the specific production of a limited range of goods or services to increase efficiency and productivity.

Comparative Advantage

Producing goods or services at a lower opportunity cost compared to another competitor.

Absolute Advantage

Producing more of a good or service compared to another competitor using the same amount of resources.

Competitive Market

A market structure where many firms compete each other and no single firm has a monopoly on the market price.

Supply and Demand Model

A model that demonstrates how prices and quantities of goods and services are determined in a market economy through the amount of the item and want of it.

Demand Schedule

A table that shows the quantity of a good or service and prices that the consumer is willing to buy them at.

Quantity Demanded

The amount of a good or service that consumers are willing to buy at specified price.

Demand Curve

A graph that shows the demand schedule, demonstrating the relationship between good price and quantity demanded.

Law of Demand

Principle that as the price of a good decreases, the quantity demanded increases, and conversely, as the price of a good increases, the quantity demanded decreases.

Change in Demand

A shift in the demand curve due to other confounding variables or factors such as income changes or loss of interest.

Movement Along the Demand Curve

Change in the quantity demanded due to a change in the price of the good, shown as movement along the existing demand curve.

Substitutes

Goods that replace each other; increasing the price of one good increases the demand for its substitute.

Complements

Goods that are consumed together; increasing the price of one good decreases demand for its complement.

Ex: Cereal complements milk, but as milk grows more expensive cereal will fall in demand.

Normal Good

A good where demand increases as consumer incomes rise.

Inferior Good

A good where demand decreases as consumer incomes rise.

Ex: foregoing the generic brand of food at the store for the better tasting name brand as you have more money to spend on food.

Individual Demand Curve

Curve showing the quantity of a good or service that an individual is willing to buy at different prices.

Quantity Supplied

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

Supply Schedule

A table showing the quantity of a good or service that producers are willing to sell at different prices.

Supply Curve

A curve of the supply schedule, showing the relationship between the price of a good and the quantity supplied.

Law of Supply

As the price of a good increases, the quantity supplied increases, conversely, as the price falls, the quantity supplied also falls.

Change in Supply

A shift in the supply curve due to confounding variables or other factors like change in production technology or rising material prices for inputs.

Movement Along the Supply Curve

Change in amount supplied due to change in price of the good, which is seen as movement along the existing supply curve.

Input

Resources used in in the production of goods and services

Individual Supply Curve

A curve that shows the quantity of a good that a single producer is willing to supply at different prices.

Equilibrium

A point in market condition where quantity demanded equals quantity supplied, resulting in no price change.

Equilibrium Price

The price point where the quantity of the good demanded by consumers equals quantity supplied.

Market-Clearing Price

Akin to Equilibrium Price, price-point where there is neither a surplus nor shortage in the market for a good.

Equilibrium Quantity

The amount of a good or service that is consumed at the equilibrium price.

Surplus

Situation in which the quantity supplied exceeds demand at a given price.

Shortage

A lack of the necessary quantity supplied to meet the demanded quantity at a given price.

Price Controls

Government instated limits on the minimums or maximums of prices that can be charged in a market.

Price Ceilings

The maximum price for a good or service as set by the government,

Price Floors

The minimum price for a good or service as set by the government.
