Overview of Economics
- Definition: Study of how individuals and societies allocate scarce resources.
- Branches:
- Microeconomics: Focuses on individual agents and markets.
- Macroeconomics: Studies the economy as a whole, including national policies.
Key Concepts
- Scarcity: Limited nature of resources available to meet unlimited wants.
- Opportunity Cost: The cost of the next best alternative foregone when making a decision.
- Supply and Demand:
- Law of Demand: As price decreases, quantity demanded increases.
- Law of Supply: As price increases, quantity supplied increases.
- Equilibrium: Point where supply equals demand.
Economic Systems
- Traditional: Based on customs and traditions.
- Command: Central authority makes decisions (e.g., socialism).
- Market: Decisions made through market interactions (e.g., capitalism).
- Mixed: Combines elements of command and market systems.
Economic Indicators
- Gross Domestic Product (GDP): Total value of goods and services produced.
- Unemployment Rate: Percentage of the labor force that is jobless.
- Inflation Rate: Rate at which the general level of prices for goods and services rises.
The Role of Government
- Regulation: Ensures fair practices and competition.
- Fiscal Policy: Government spending and taxation decisions to influence the economy.
- Monetary Policy: Management of the money supply and interest rates by the central bank.
Key Theories
- Classical Economics: Advocates for free markets and minimal government intervention.
- Keynesian Economics: Emphasizes the role of government in regulating the economy.
- Supply-Side Economics: Focuses on boosting supply to spur economic growth.
Market Structures
- Perfect Competition: Many buyers/sellers, homogeneous products.
- Monopoly: Single seller controls the market.
- Oligopoly: Few firms dominate the market.
- Monopolistic Competition: Many firms, differentiated products.
International Economics
- Trade: Exchange of goods/services between countries.
- Comparative Advantage: Ability of a country to produce goods at a lower opportunity cost.
- Balance of Payments: Summary of all economic transactions between residents of a country and the rest of the world.
Current Issues

Economics: Core Definition and Branches
- Economics studies resource allocation by individuals and societies.
- Microeconomics analyzes individual agents and markets.
- Macroeconomics examines the entire economy, including national policies.
Fundamental Economic Concepts
- Scarcity: Resources are limited relative to unlimited wants.
- Opportunity cost: Value of the best alternative forgone.
- Supply and Demand: Demand rises as price falls; supply rises as price rises. Market equilibrium occurs where supply equals demand.
Economic Systems: A Comparison
- Traditional economies rely on customs and traditions.
- Command economies are centrally planned (e.g., socialism).
- Market economies use market interactions (e.g., capitalism).
- Mixed economies blend aspects of command and market systems.
Key Economic Indicators
- Gross Domestic Product (GDP): Measures the total value of goods and services produced.
- Unemployment Rate: Percentage of the labor force without jobs.
- Inflation Rate: Rate of increase in the general price level.
The Government's Economic Role
- Regulation: Government oversight to ensure fair practices and competition.
- Fiscal Policy: Government spending and taxation to influence the economy.
- Monetary Policy: Central bank management of the money supply and interest rates.
Major Economic Theories

- Monopoly: One seller dominates the market.
- Oligopoly: A few firms control the market.
- Monopolistic Competition: Many firms, differentiated products.
International Economics: Key Aspects
- Trade: Exchange of goods and services between countries.
- Comparative Advantage: A country's ability to produce goods at a lower opportunity cost.
