- Microeconomics: Examines individual and business decisions, market interactions, and the allocation of resources.
- Macroeconomics: Studies the economy as a whole, including inflation, unemployment, and national income.
3. Fundamental Economic Questions
- What to produce?
- How to produce?
- For whom to produce?
4. Supply and Demand
- Law of Demand: As price decreases, quantity demanded increases, and vice versa.
- Law of Supply: As price increases, quantity supplied increases, and vice versa.
- Market Equilibrium: The point where supply equals demand.
5. Elasticity
- Measures responsiveness of quantity demanded or supplied to changes in price.
- Price Elasticity of Demand: Percentage change in quantity demanded divided by percentage change in price.
- Income Elasticity of Demand: Measures how demand changes as consumer income changes.
6. Market Structures
- Perfect Competition: Many buyers and sellers, identical products.
- Monopoly: Single seller dominates the market.
- Oligopoly: Few sellers control majority of the market.
- Monopolistic Competition: Many sellers offer differentiated products.
7. Economic Indicators
- Gross Domestic Product (GDP): Total value of all goods and services produced in a country.
- Unemployment Rate: Percentage of the labor force that is unemployed.
- Inflation Rate: Rate at which the general level of prices for goods and services rises.
8. Fiscal and Monetary Policy
- Fiscal Policy: Government adjustments in spending and tax policies to influence the economy.
- Monetary Policy: Central bank actions that manage the money supply and interest rates.
9. International Trade
- Comparative Advantage: Ability of a country to produce goods at a lower opportunity cost than another.

10. Economic Theories
- Classical Economics: Emphasizes free markets, competition, and limited government intervention.
- Keynesian Economics: Advocates for government intervention to stabilize economic cycles.
- Supply-Side Economics: Focuses on boosting economic growth by increasing supply of goods and services.

Definition of Economics
- Economics analyzes how choices are made regarding the allocation of limited resources by individuals, businesses, and governments.
- It encompasses the production, distribution, and consumption processes of goods and services.
Microeconomics vs. Macroeconomics
- Microeconomics deals with the behavior of individual units, such as households and firms, as well as market mechanisms and resource allocations.
- Macroeconomics examines the economy in its entirety, focusing on national indicators such as inflation rates, unemployment levels, and the total income generated within a country.
Fundamental Economic Questions
- Key inquiries include:
- What goods and services should be produced?
- What methods should be utilized for production?
- Who will be the ultimate consumers of these goods and services?
Supply and Demand
- Law of Demand: Indicates an inverse relationship between price and quantity demanded; when price falls, demand rises.
- Law of Supply: Suggests a direct relationship between price and quantity supplied; higher prices prompt increased supply.
- Market Equilibrium: Achieved when the quantity supplied equals the quantity demanded at a specific price.
Elasticity
- Elasticity gauges how sensitive demand or supply is to price changes.
- Price Elasticity of Demand: Calculated as the percentage change in quantity demanded relative to the percentage change in price.
- Income Elasticity of Demand: Assesses how demand shifts in response to changes in consumer incomes.
Market Structures
- Perfect Competition: Characterized by numerous sellers and buyers with identical offerings.
- Monopoly: A market structure where a single seller dominates, leading to less competition.
- Oligopoly: Few large sellers control substantial portions of the market, often leading to collaborative pricing.
- Monopolistic Competition: Many sellers offer products that are similar but differentiated, allowing for some pricing power.
Economic Indicators
- Gross Domestic Product (GDP): Reflects the monetary value of all finished goods and services produced within a country during a specific time period.
- Unemployment Rate: Measures the percentage of the labor force that is actively seeking work but unable to find employment.
- Inflation Rate: Indicates the rate at which the overall price level of goods and services rises, eroding purchasing power.
Fiscal and Monetary Policy
- Fiscal Policy: Involves government measures, such as spending and taxation, aimed at influencing the economic activity.
- Monetary Policy: Central bank strategies that adjust the money supply and manipulate interest rates to control economic growth and stability.
International Trade
- Comparative Advantage: A principle asserting that countries benefit from producing goods at a lower opportunity cost, enabling trade.
- Trade Barriers: These include tariffs, quotas, and subsidies that governments impose to protect domestic industries and limit foreign competition.
Economic Theories
- Classical Economics: Advocates for minimal government intervention in markets, relying on competition to drive efficiency.
- Keynesian Economics: Suggests that active government intervention is necessary to manage economic fluctuations and stimulate demand.
- Supply-Side Economics: Posits that economic growth is most effectively achieved by enhancing the production capacity of the economy.
Contemporary Issues
- Globalization influences economic interactions and labor markets across nations.
- Income inequality raises concerns regarding economic fairness and social stability.
- Environmental economics stresses the importance of integrating sustainable practices into economic decision-making for future growth.
