Key Concepts

Scarcity
- Represents the limited availability of resources against infinite wants, necessitating choices and trade-offs.

Supply and Demand
- Supply: The amount of goods/services producers are willing to sell.
- Demand: The amount consumers wish to purchase at different price points.
- Equilibrium: The intersection point where supply equals demand.
Market Structures
- Perfect Competition: Many firms offer identical products with no barriers to market entry.
- Monopoly: One firm holds significant market power with a unique product and high entry barriers.
- Oligopoly: A few firms dominate the market and can either compete or collaborate.
- Monopolistic Competition: Many firms sell differentiated products, allowing for some degree of pricing power.

- Gross Domestic Product (GDP): Measures the total economic output of goods and services produced within a country.
- Unemployment Rate: Proportion of the labor force that is jobless and actively seeking employment.
- Inflation Rate: Indicates the pace at which general prices for goods and services are rising.

Economic Systems

Capitalism: Characterized by private ownership and market-driven principles with the goal of profit maximization.
Socialism: Emphasizes public or collective ownership, often with planned economic activities aimed at equality.
Mixed Economy: Integrates both capitalist and socialist elements, balancing private enterprise with public interests.

Analyzes balance of payments, which tracks all transactions between a nation’s residents and the global market.
Discusses exchange rates, showing the value relationship between different currencies.

Current Trends

Sustainability: Emphasizes the importance of environmentally considerate practices in pursuing economic development.
Technological Impact: Underlines the role of technological advancements in boosting productivity and reshaping labor markets.
