📖 1. Median and Data Sets

🔑 Key Concepts & Definitions

• Median: The middle value that divides a data set or geometric shape into two equal halves.

📖 2. Microeconomics and Macroeconomics

★ Must-know

📌 Microeconomics and macroeconomics are the two branches contrasted in the course’s introduction to business economics.

Further detail

• The listed topics in business economics are:
  • supply and demand
  • elasticities
  • costs, revenues and profitability
  • taxes and subsidies
  • externalities
  • competition and industrial organisation

💡 Memory Hook

Microeconomics focuses on individual markets; macroeconomics takes the broader economic perspective.

📖 3. Scarcity, Trade-Offs, and Production

🔑 Key Concepts & Definitions

• Scarcity: Occurs when resources are limited compared with people’s wants and needs.
• Trade-Off: The choice between options in which choosing one means giving up another.
• Opportunity Cost: The value of the best alternative given up when making a choice.
• Production Possibilities Frontier: Shows the maximum combinations of two goods or services an economy can produce with its available resources and technology.

📝 Essential Points

📌 On a production possibilities frontier, points on the frontier are efficient, whereas points inside it are inefficient.

💡 Memory Hook

Scarcity → trade-offs → opportunity cost.

📖 4. Firms, Inputs, and Output

🔑 Key Concepts & Definitions

• Inputs: Resources used in a firm’s production process.
• Output: The goods or services produced by a firm.

★ Must-know

📐 Formula - A firm’s production is represented as $Q=f(X_1,\ldots,X_n)$, where $Q$ is output and the $X$ terms are inputs.

Further detail

• The factors of production listed are:
  • capital
  • labour
  • land or natural resources
  • intermediates

💡 Memory Hook

Inputs → production process → output.

📖 5. Business Ownership and Objectives

🔑 Key Concepts & Definitions

• Public Firms: Organizations owned or controlled by the government that generally aim to provide goods or services considered important for society rather than focusing only on profit.

📝 Essential Points

📌 Private firms are described as aiming to make profits, while private non-profit businesses aim to provide goods or services rather than maximize profit.

💡 Memory Hook

Private profit-seeking firms differ from private non-profits and public firms in their stated objectives.

📖 6. Economic Allocation Systems

📝 Essential Points

• The three allocation systems listed are:
  • the market economy
  • the mixed economy
  • the centrally planned economy
