Basic Economic Principles

Types of Economics

• Microeconomics analyzes the behavior of individual consumers and firms, focusing on specific markets.
• Macroeconomics explores broader economic phenomena, including inflation rates, unemployment levels, and Gross Domestic Product (GDP).

Economic Systems

• A market economy relies on individual decision-making, rooted in supply and demand mechanisms.
• In a command economy, a central authority directs production and distribution decisions.
• A mixed economy merges elements of both market and command systems, leveraging the advantages of each.

Key Economic Indicators

• Gross Domestic Product (GDP) quantifies the total market value of all goods and services produced within a country's borders.
• The unemployment rate measures the proportion of the labor force that is currently jobless and seeking employment.
• The inflation rate tracks the pace at which the overall price level of goods and services increases over time.

Market Structures

• Perfect competition exists when numerous firms offer identical products, facilitating easy market entry and exit.
• A monopoly is characterized by a single firm that dominates the market, providing unique products without close substitutes.
• An oligopoly involves a limited number of firms that have significant market power, potentially leading to collusion among them.

Fiscal and Monetary Policy
