• Opportunity Cost: Represents the value of the next best alternative that is sacrificed when making a choice, highlighting trade-offs in decision-making.
• Supply and Demand: Core economic model examining how the quantity of a product available influences its price and consumer demand.

Types of Economics

• Microeconomics: Analyzes the behavior and decision-making of individual agents, including consumers and businesses, and their interactions in specific markets.
• Macroeconomics: Focuses on aggregate economic phenomena such as national income, overall unemployment rates, inflation trends, and Gross Domestic Product (GDP).

Economic Systems

• Socialism: System where the government owns and manages production resources, aiming for equal distribution of wealth among citizens.
• Mixed Economy: Combines elements of both capitalism and socialism, utilizing both private enterprise and government intervention.

Market Structures

• Perfect Competition: Characterized by many firms producing identical products, with unobstructed entry and exit from the market.
• Monopolistic Competition: Describes markets with many producers of differentiated products, allowing some degree of pricing power.
• Oligopoly: Market structure dominated by a few firms that may either collaborate or compete against each other.
• Monopoly: Situation where a single company has exclusive control over a product or service, limiting competition.

Key Economic Indicators

• Gross Domestic Product (GDP): Measures the total economic output of a country, reflecting the value of all goods and services produced over a specific time period.
• Unemployment Rate: Indicates the percentage of the labor force that is jobless and actively seeking employment, serving as a gauge for economic health.
• Inflation Rate: Represents the percentage increase in price levels over time, indicating how quickly prices are rising and eroding purchasing power.

Fiscal and Monetary Policy

• Fiscal Policy: Involves government decisions regarding taxation and spending aimed at influencing economic activity and growth.
• Monetary Policy: Conducted by a central bank to control the money supply and interest rates, aiming to stabilize the economy and manage inflation.

International Trade

• Trade Barriers: Policies such as tariffs and quotas that governments use to regulate international trade, potentially protecting domestic industries.
• Exchange Rates: Determines the value of one currency relative to another, influencing international trade and investment decisions.

Economic Theories
