Study Notes
Introduction
- Economics studies how societies transform resources into goods and services
- Economic analysis is based on assumptions about human behavior
- Microeconomics analyzes individual choices while macroeconomics considers overall economic performance
Fundamental Economic Concepts
- Scarcity: Limited resources, unlimited wants
- Trade-offs: Choosing one option means giving up another
- Opportunity cost: The value of the best alternative foregone
- Rationality: Individuals make choices by comparing benefits and opportunity costs
Microeconomics
- Markets: Groups of buyers and sellers for a specific good or service
- Demand: Quantity of a good or service that consumers are willing and able to buy at various prices
- Shifts in demand: Changes in consumer preferences, income, prices of related goods, expectations , number of buyers
- Supply: Quantity of a good or service that producers are willing and able to sell at various prices
- Shifts in supply: Changes in input prices, technology, number of sellers, and expectations
- Market equilibrium: The point where supply and demand intersect, determining price and quantity
- Perfectly competitive markets: Many buyers and sellers, identical products, free entry/exit, no individual influence on price
- Imperfect competition: Monopolies, oligopolies, and monopolistic competition, where firms have some market power
Macroeconomics
- Macroeconomic issues cover overall economic performance
- Factors that determine long run economic growth and living standards, include output, living standards, employment, and inflation
- Economic growth and living standards: Output per person shows how well the economy does over time
- Unemployment: The percentage of the labor force that is actively seeking jobs, but cannot find them
- Inflation: A general increase in prices causing reduced purchasing power
- International trade: Trade between countries affecting total output, specialization, and benefits
- Macroeconomic indicators: Gross Domestic Product (GDP), the rate of inflation, and the unemployment rate
Economics Meets Ecology
- Externalities: Unintended effects of economic activities on others
- Negative externalities: Activities impose costs (e.g., pollution)
- Positive externalities: Activities create benefits (e.g., bee pollination)
- Common property: Resources without clear ownership, subject to overuse
- Public goods: Goods that are both non-rivalrous and non-excludable (e.g., national defense)
- Public bads: Non-excludable and rivalrous costs (e.g., pollution)
- Sustainability: The ability of the environment and economic systems to continue indefinitely without damaging the future
Basic Policy Responses
- Government intervention: Managing market failures through regulation and taxes; e.g., establishing minimum wage, rent regulations
- Price controls: Setting maximum or minimum prices
- Taxes: Government leverages to raise funds for public expenditure, to correct market failures
