Core Concepts

• Scarcity: Limited resources vs. unlimited wants.
• Opportunity Cost: Value of the next best alternative forgone when making a choice.

Branches of Economics

• Microeconomics: Analyzes actions of individual consumers and businesses, focusing on the concepts of supply, demand, pricing, and market competition.
• Macroeconomics: Investigates overall economic performance on a national scale, assessing indicators such as Gross Domestic Product (GDP), unemployment rates, and inflation levels.

Core Concepts

• Scarcity: Represents the conflict between limited resources and unlimited human wants.
• Opportunity Cost: Refers to the value of the best alternative not chosen when a decision is made.
• Supply and Demand: Central model in economics that determines how prices are set in a market.
• Elasticity: Quantifies how much the quantity demanded or supplied responds to price changes.

Economic Systems

• Capitalism: Characterized by private ownership, free markets, and competitive business environments.
• Socialism: Focuses on collective ownership, often involving centralized planning of the economy.
• Mixed Economy: Blends elements of both capitalism and socialism, balancing free markets with government intervention.

Key Indicators

• Gross Domestic Product (GDP): Measures the total economic output of a country, indicating its economic health.
• Unemployment Rate: Indicates the percentage of the workforce that is unemployed and actively seeking work.
• Inflation Rate: Reflects the pace at which the overall price levels of goods and services rise.

Economic Theories

• Classical Economics: Stresses the importance of free markets and the self-regulating characteristics of economies.
• Keynesian Economics: Supports government involvement in the economy to manage economic cycles and promote stability.
• Monetarism: Focuses on the control of the money supply as a means to regulate economic activity.

• Sustainable Economics: Emphasizes practices that ensure long-term ecological health and resource sustainability.
• Digital Economy: Investigates how advancements in technology and the internet transform economic activities and business models.
