Study Notes

Introduction to Economics

Economics is the social science studying how societies allocate scarce resources to satisfy unlimited wants and needs.
It's divided into microeconomics and macroeconomics.
Microeconomics focuses on individual agents (households, firms) and their market interactions.
Macroeconomics analyzes the aggregate economy, encompassing inflation, unemployment, and economic growth.

Key Concepts in Economics

Scarcity: Limited resources contrast with unlimited wants, forcing choices and trade-offs.
Opportunity Cost: The value of the next best alternative foregone.
Supply and Demand: Fundamental market forces. Demand is consumer desire; supply is producer willingness.
Market Equilibrium: The intersection of supply and demand, where there's no excess supply or demand.
Elasticity: Measures responsiveness of one variable to changes in another.
Price elasticity of demand: Quantity demanded's reaction to price changes.
Cross-price elasticity: One demand's sensitivity to another good's price.
Production Possibilities Frontier (PPF): Represents possible output combinations given resources and technology.
Points on the frontier are efficient; inside, inefficient; outside, unattainable.
Comparative Advantage: Producing at a lower opportunity cost than another. Crucial for international trade.
Externalities: Costs or benefits imposed on third parties by economic transactions.
Positive externalities are beneficial; negative externalities, detrimental (e.g., pollution).

Microeconomics

Market Structures: Varying market organizations: perfect competition, monopoly, oligopoly, monopolistic competition.
Consumer Behavior: Examines choices based on utility maximization, preferences, and budget constraints.
Production: Production function links inputs (labor, capital) to output, and economies of scale are cost advantages from increased output.
Cost Analysis: Businesses face fixed and variable costs. Marginal cost is the extra cost from producing one more unit.

Macroeconomics

Gross Domestic Product (GDP): Measures total value of final goods/services produced within a country.
Inflation: Sustained price increase for goods/services.
Unemployment: Percentage of labor force actively seeking but unable to find jobs.
Fiscal Policy: Government use of taxes and spending to influence the economy.
Monetary Policy: Central bank's actions to manage money supply and interest rates.
Economic Growth: Increased production of goods/services over time, driven by investment, technology, and human capital.
Business Cycles: Fluctuations in economic activity around a long-term trend.
International Trade: Exchange of goods/services between countries.

Economic Systems

Capitalism: Private individuals and businesses own the means of production.
Socialism: Means of production are owned and controlled by the community.
Mixed Economy: Combines elements of capitalism and socialism, balancing private enterprise and government intervention — the most prevalent economic arrangement globally.

Conclusion

Economics offers frameworks for understanding decision-making by individuals, businesses, and governments.
Its principles apply to numerous issues, from personal finance to national policies on trade, taxation, and regulation.
