Study Notes

Introduction to Economics

Economics is the social science studying how societies allocate scarce resources to satisfy unlimited wants and needs.
It analyzes the production, distribution, and consumption of goods and services.
Microeconomics focuses on individual actors like consumers and firms.
Macroeconomics examines the complete economy, including inflation, unemployment, and growth.

Key Economic Concepts

Scarcity: Limited resources against unlimited wants forces choices.
Opportunity Cost: The forgone value of the next best alternative.
Incentives: Motivate individuals and firms to act.
Supply and Demand: Buyer and seller preferences influence prices and quantities.
Market Equilibrium: Supply and demand intersect, setting price and quantity.
Elasticity: Responsiveness of one variable to changes in another.

Types of Economic Systems

Traditional Economy: Decisions based on customs and traditions.
Command Economy: Government controls resources and production.
Market Economy: Individuals and firms decide resource allocation based on supply and demand.
Mixed Economy: Combines elements of market and command systems. The government plays a role in regulating markets and providing public goods, although market mechanisms remain significant.

Economic Models

Simplified versions of reality for understanding and predicting.
Graphical and mathematical models are used.
Assumptions are needed – models are only as good as their foundations.
Models are refined by gathering data and analysis.

Economic Growth

Sustained increase in the production of goods and services.
Factors include innovation, capital, human capital, and institutional quality.

Key Economic Schools of Thought

Classical Economics: Markets self-regulate with free markets.
Keynesian Economics: Government intervention can manage aggregate demand.
Monetarism: Money supply affects economic activity and prices levels.
Austrian Economics: Emphasizes individual actions and spontaneous market order; often critical of intervention.
Behavioral Economics: Examines how psychological factors influence decisions.

Economic Indicators

Gross Domestic Product (GDP): Measures the total value of final goods and services produced within a country.
Inflation: General price increase.
Unemployment: Percentage of the labor force actively seeking but without work.
Interest Rates: Cost of borrowing money.
Consumer Price Index (CPI): Measures average price changes for consumer goods/services.
Producer Price Index (PPI): Measures average changes in prices received by producers.
Balance of Payments: Tracks flow of goods, services, and capital across borders; shows the import/export difference.

Role of Government in the Economy

Provides public goods (defense, roads).
Regulates markets to prevent monopolies and protect consumers.
Redistributes income through taxes and social programs.
Manages money supply and interest rates.

International Trade

Exchange of goods and services across borders.
Benefits from specialization and comparative advantage.
Can create trade imbalances (deficits, surpluses).
Influenced by tariffs, quotas, and barriers.
Globalization has increased the interconnectedness of countries through trade and investment.

Economic Challenges and Issues

Income inequality: Unequal distribution of income.
Unemployment: High unemployment harms the economy and individuals.
Inflation: Rising general price level.
Economic growth: Fluctuations affect employment, wages, and well-being.
Environmental concerns: Resource depletion, pollution, and climate change.
Globalization: Challenges like job loss, income inequality, and resource exploitation.
