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).
• Equilibrium: The point where supply equals demand.

5. Types of Markets

• Perfect Competition: Many sellers, homogeneous products, free entry and exit.
• Monopoly: Single seller, unique product with high barriers to entry.
• Oligopoly: Few sellers, products may be homogeneous or differentiated.

6. Economic Indicators

• Gross Domestic Product (GDP): Total value of goods/services produced over a specific time.
• Unemployment Rate: Percentage of labor force that is jobless and actively seeking employment.
• Inflation Rate: The rate at which the general level of prices for goods and services rises.

7. Fiscal and Monetary Policy

• Fiscal Policy: Government spending and taxation decisions to influence the economy.
• Monetary Policy: Central bank actions that manage money supply and interest rates.

8. Consumer Behavior

• Utility: Satisfaction or pleasure derived from consuming goods/services.
• Marginal Utility: Additional satisfaction from consuming one more unit of a good/service.

9. Production and Costs

• Factors of Production: Land, labor, capital, and entrepreneurship.
• Opportunity Cost: The cost of the next best alternative foregone when making a decision.

10. International Trade

• Comparative Advantage: Ability of a country to produce a good at a lower opportunity cost than another.
• Trade Barriers: Tariffs, quotas, and regulations that restrict international trade.

11. Market Failures

• Common causes: Externalities, public goods, and information asymmetries.

12. Economic Systems

• Capitalism: Private ownership of resources and free market.
• Socialism: Collective or governmental ownership of resources.
• Mixed Economy: Combination of capitalism and socialism.

13. Behavioral Economics

Definition of Economics

• Economics investigates the allocation of scarce resources among individuals, businesses, and societies.
• Central to economics are decision-making processes and the trade-offs that these entail.

Microeconomics vs. Macroeconomics

• Microeconomics focuses on the behavior of individual units such as consumers and firms and their market interactions.
• Macroeconomics views the economy as a whole, studying large-scale economic factors like inflation, unemployment, and overall economic growth.

Fundamental Economic Questions

• Key decisions in economics revolve around what to produce, how to produce it, and for whom the production is intended.

Supply and Demand

• Law of Demand indicates that when prices decrease, the quantity demanded increases, and vice versa.
• Law of Supply suggests that higher prices lead to an increase in the quantity supplied, and conversely.
• Market Equilibrium occurs where the quantity supplied equals the quantity demanded.

Types of Markets

• Perfect Competition features numerous sellers offering identical products with easy market entry and exit.
• Monopoly involves a single seller dominating the market with unique products and high entry barriers.
• Oligopoly consists of a few sellers that may offer similar or differentiated products.

Economic Indicators

• Gross Domestic Product (GDP) measures the total value of goods and services produced within a specified timeframe.
• Unemployment Rate represents the percentage of the labor force that is jobless and actively searching for work.
• Inflation Rate quantifies the pace at which the overall price level of goods and services is rising.

Fiscal and Monetary Policy

• Fiscal Policy is shaped by government spending and tax decisions intended to steer the economy.
• Monetary Policy comprises actions taken by a central bank to adjust the money supply and influence interest rates.

Consumer Behavior

• Utility describes the satisfaction gained from consuming goods or services.
• Marginal Utility refers to the extra satisfaction derived from consuming an additional unit of a product.

Production and Costs

• Factors of Production include land, labor, capital, and entrepreneurship, all essential for producing goods/services.
• Opportunity Cost reflects the value of the next best alternative that is foregone when making a choice.

International Trade

• Comparative Advantage means a country can produce a good at a lower opportunity cost compared to another country.
• Trade Barriers encompass tariffs, quotas, and regulations that hinder international trade.

Market Failures

• Market Failures arise when goods or services are not allocated efficiently across the economy.
• Factors contributing to market failures include externalities, public goods, and information asymmetries.

Economic Systems

• Capitalism is characterized by private ownership of resources and a free market economy.
• Socialism encompasses collective or governmental ownership of resources and assets.
• Mixed Economy combines elements of both capitalism and socialism to varying degrees.

Behavioral Economics

• Behavioral Economics examines psychological influences on economic decision-making, diverging from the assumption of complete rationality in traditional economics.
