-
Macroeconomics:
- Studies the economy as a whole.
- Examines aggregate indicators such as GDP, unemployment rates, and inflation.
Core Principles
-
Supply and Demand:
- Supply: The quantity of a good or service that producers are willing to sell at different prices.

Basic Definitions
- Economics examines the allocation of scarce resources among competing wants by individuals, businesses, and governments.
- Scarcity refers to the limited availability of resources compared to infinite human desires.
Major Branches of Economics
- Microeconomics analyzes the behavior of individuals and businesses, focusing on supply and demand, pricing strategies, and consumer choices.
- Macroeconomics looks at the economy as a unified system, emphasizing aggregate metrics such as Gross Domestic Product (GDP), unemployment rates, and inflation.
Core Principles
- Supply indicates how much of a good or service producers are willing to offer at varying prices, while demand reflects consumers' willingness to purchase at those prices.
- Market equilibrium is achieved when supply meets demand.
- Opportunity cost is the trade-off representing the next best alternative given up when a choice is made.
- Marginal analysis involves assessing the additional benefits against the additional costs of an action to determine its viability.
Economic Systems
- Capitalism is characterized by private ownership of resources and a market-driven approach to economic decision-making.
- Socialism involves collective or government ownership of resources with centralized planning to distribute resources.
- A mixed economy incorporates aspects of both capitalism and socialism, balancing private enterprise with public control.
Key Economic Indicators
- GDP gauges the total monetary value of all goods and services produced within a country during a specified timeframe.
- Inflation measures the increase in general price levels for goods and services, effectively decreasing the purchasing power of currency.
- The unemployment rate expresses the proportion of the labor force that is without jobs while actively seeking employment.
Market Structures
- Perfect competition features numerous buyers and sellers, homogeneous products, and unrestricted market entry and exit.
- A monopoly is characterized by one seller controlling the market with no close substitutes available.
- Oligopoly consists of a few firms dominating the market, potentially leading to collusion among competitors.
