Economics Chapter on Scarcity and Choice

Study Notes

Economics

Economics studies how societies allocate scarce resources to meet unlimited needs and wants.
Key concepts include scarcity, choice, opportunity cost, production possibilities frontier (PPF), factors of production (land, labor, capital, entrepreneurship), and economic systems (market, command, mixed).

Scarcity

Scarcity is the fundamental economic problem. Resources are limited, while human wants are unlimited.
This forces individuals, businesses, and governments to make choices about resource use.

Choice

Choice is selecting among alternatives.
Choosing one option means forgoing another due to scarcity.

Opportunity Cost

Opportunity cost is the value of the next best alternative forgone.
It represents trade-offs in decision-making.
Example: The opportunity cost of attending college is lost income from working.

Production Possibilities Frontier (PPF)

The PPF graphically shows maximum output combinations of two goods with available resources and technology.
It visually represents opportunity cost. Moving along the PPF means trade-offs between goods.
Points inside the PPF are inefficient resource use.
Points outside the PPF are currently unattainable.

Factors of Production

Land: Natural resources (e.g., minerals, water, forests).
Labor: Human effort, skills, and knowledge.
Capital: Man-made tools, machinery, and infrastructure. Includes physical and human capital (knowledge, skills).
Entrepreneurship: Combining factors to create new goods/services and innovate, taking risks. Drives economic growth.

Economic Systems

Market Economy: Individuals and businesses primarily make production/consumption decisions in markets. Prices are set by supply and demand. Minimal government intervention.
Command Economy: The government controls production, deciding what/how/for whom to produce. Little individual economic choice; can lead to shortages and surpluses.
Mixed Economy: Combines market and command elements. A blend of government intervention and market mechanisms. Most real-world economies are mixed.
Basic Economic Questions: What to produce? How to produce? For whom to produce? These questions are answered differently in each economic system.
Economic Growth: Increase in an economy's productive capacity over time, measured by increases in real GDP.
Circular Flow of Income: Model of goods, services, and money flow between households and businesses.
Demand: Consumer willingness and ability to buy goods/services at various prices.
Supply: Producer willingness and ability to sell goods/services at various prices.
Equilibrium: Market price where quantity demanded equals quantity supplied. Balance between supply and demand.
Market Structure: Different market organizations. Includes perfect competition, monopolies, oligopolies, and monopolistic competition.
Microeconomics: Studies individual markets and their interactions.
Macroeconomics: Studies the overall economy and its aggregate measures (e.g., inflation, unemployment, economic growth).
Gross Domestic Product (GDP): Total monetary value of final goods/services produced within a country's borders.
Inflation: General increase in price level of goods/services over time.
Unemployment: Percentage of the labor force seeking employment but unable to find it.
Poverty: Lack of sufficient income for basic needs (food, shelter, clothing).
