Key Concepts in Economics
Definition
- Economics is the study of how individuals, businesses, governments, and societies allocate scarce resources to satisfy unlimited wants.
Branches of Economics
-
Microeconomics:
- Focuses on individual units (consumers, firms).
- Analyzes supply and demand, pricing, and consumer behavior.
-
Macroeconomics:
- Examines the economy as a whole.
- Involves national income, total output, inflation, and unemployment.
Economic Systems
- Traditional Economy: Based on customs and traditions.
- Command Economy: Central authority makes decisions (e.g., socialism).
- Market Economy: Decisions made through supply and demand (e.g., capitalism).
- Mixed Economy: Combines elements of market and command economies.
Key Economic Indicators
- Gross Domestic Product (GDP): Total value of goods and services produced in a country.
- Inflation Rate: Measure of the rate of rising prices.
- Unemployment Rate: Percentage of the labor force that is unemployed.
- Balance of Trade: Difference between a country's exports and imports.
Supply and Demand
- Law of Demand: Quantity demanded falls as price rises.
- Law of Supply: Quantity supplied rises as price increases.
- Market Equilibrium: Point where supply equals demand.
Types of Goods
- Normal Goods: Demand increases as income rises.
- Inferior Goods: Demand decreases as income rises.
- Substitutes: Goods that can replace each other (e.g., butter and margarine).
- Complements: Goods that are consumed together (e.g., printers and ink).
Economic Theories
- Classical Economics: Belief in free markets and minimal government intervention.
- Keynesian Economics: Advocates for government intervention to manage economic cycles.
- Monetarism: Focuses on the control of money supply to regulate the economy.
Market Structures
- Perfect Competition: Many sellers, identical products, no barriers to entry.
- Monopoly: Single seller dominates the market.
- Oligopoly: Few sellers control the market; products can be similar or differentiated.
- Monopolistic Competition: Many sellers with differentiated products.
Fiscal and Monetary Policy
- Fiscal Policy: Government adjustments in spending and taxation to influence the economy.
- Monetary Policy: Central bank actions to control money supply and interest rates.
Externalities
- Positive Externality: Benefit received by third parties (e.g., education).
- Negative Externality: Cost imposed on third parties (e.g., pollution).
International Trade
- Comparative Advantage: Country produces goods at lower opportunity costs.
- Trade Barriers: Tariffs, quotas, and regulations to control trade.
Economic Development
- Focuses on improving economic health and quality of life in a region.
- Indicators include literacy rates, health care access, and income levels.
Definition of Economics

- Inflation Rate indicates the rate at which prices for goods and services rise.
- Unemployment Rate reflects the percentage of the labor force actively seeking work but unable to find it.
- Balance of Trade quantifies the difference between a country's exports and imports.
### Supply and Demand
- Law of Demand states that as the price of a good or service rises, the quantity demanded decreases.
- Law of Supply indicates that as the price of a good or service rises, the quantity supplied increases.
- Market Equilibrium occurs when the quantity supplied equals the quantity demanded.
Types of Goods
- Normal Goods experience increased demand as income rises.
- Inferior Goods see reduced demand when income increases.
- Substitutes are goods that can replace one another, like butter and margarine.
- Complements are goods that are consumed together, like printers and ink.
Economic Theories
- Classical Economics emphasizes free markets and limited government intervention.
- Keynesian Economics advocates for government intervention to manage economic fluctuations.
- Monetarism focuses on controlling the money supply to regulate the economy.
Market Structures
- Perfect Competition features numerous sellers, identical products, and free entry and exit.
- Monopoly exists when a single seller dominates the market.
- Oligopoly involves a few sellers dominating the market, with products potentially similar or differentiated.
- Monopolistic Competition has many sellers offering slightly differentiated products.
Fiscal and Monetary Policy
- Fiscal Policy refers to government actions, like spending or taxation, to influence economic activity.
- Monetary Policy involves the central bank's actions to control the money supply and interest rates.
Externalities
- Positive Externalities benefit third parties, like education.
