Microeconomics: The Basic Economic Problem, Factors of Production, and Opportunity Cost

The Basic Economic Problem and Resource Scarcity

  • Definition of Microeconomics:

    • Microeconomics is the study of how to best solve the basic economic problem.

  • The Basic Economic Problem:

    • The basic economic problem centers on how to allocate scarce resources given unlimited human wants.

    • Human individuals possess real, unlimited desires and wants.

    • The planet does not provide enough resources to fully satisfy these unlimited wants, making resources scarce.

The Four Factors of Production (CELL)

  • Definition of Factors of Production:

    • In economics, resources are also referred to as factors of production.

    • Factors of production are resources that, when combined together, produce goods and services.

  • Mnemonic for Factors of Production:

    • The acronym CELL stands for the four factors of production:

    • C — Capital

    • E — Enterprise

    • L — Land

    • L — Labor

  • Detailed Breakdown of the Four Factors:

    • Capital:

    • Capital does not mean money in economics.

    • Defined as man-made aids to production (things made by humans that allow for greater production of goods and services to take place).

    • Examples include:

      • Machinery

      • Tractors and vehicles

      • Factories

      • Shop premises

      • Schools

      • Hospitals

      • Computers

    • Enterprise:

    • Refers to entrepreneurs and entrepreneurship.

    • Represents risk-taking individuals who innovate and produce goods and services.

    • Innovate and take risks specifically to earn profits.

    • Land:

    • Refers to natural land where goods can be produced or extracted.

    • Examples include farmland and rainforests.

    • Labor:

    • Refers to human resources and workers who produce goods and services.

  • Resource Scarcity:

    • The world does not supply an infinite quantity of these four factors of production, resulting in scarcity alongside unlimited wants.

The Three Fundamental Economic Choices in a Market Economy

  • Economics as the Study of Choice:

    • Because resources are scarce, choices must be made regarding how resources are allocated.

    • Economics is fundamentally the study of choice.

  • The Three Fundamental Choices:

    • Allocating scarce resources requires answering three core questions:

    1. What to produce?

    2. How to produce it?

    3. For whom to produce?

  • Answering Fundamental Choices in a Market Economy:

    • What to produce:

    • Private businesses decide what to produce based on consumer demand.

    • How to produce it:

    • Businesses decide based on what is most cost-effective and productive in order to minimize the use of scarce resources.

    • Businesses that succeed at producing at the lowest cost while minimizing scarce resource usage survive in the market.

    • For whom to produce:

    • Allocated to individuals who possess sufficient income to afford goods and services in the market.

    • General market rule: if a consumer can afford a good or service, they receive it.

    • The government can step in to assist, but primary allocation relies on income affordability.

Opportunity Cost and Decision Evaluation

  • Definition of Opportunity Cost:

    • Opportunity cost is the cost of the next best alternative foregone when a choice is made.

    • It serves as the fundamental concept used in economics to measure whether choices are good or bad.

  • Measuring Choices Using Opportunity Cost:

    • To evaluate a decision, a value is assigned to the chosen option and compared to the value of the next best alternative foregone.

    • Evaluation Criteria:

    • Good Decision:       Value of Current Choice>Value of Opportunity Cost\text{Value of Current Choice} > \text{Value of Opportunity Cost}

    • Bad Decision:       Value of Opportunity Cost>Value of Current Choice\text{Value of Opportunity Cost} > \text{Value of Current Choice}

  • Reallocation of Resources:

    • When the value of the opportunity cost exceeds the value of the current choice, a bad decision has been made.

    • In this scenario, resources should be reallocated away from the current choice and toward the next best alternative (the opportunity cost).

  • Application:

    • Understanding opportunity cost provides the foundation for evaluating real-world economic decision-making prior to analyzing choices in greater detail using tools such as Production Possibility Frontiers (PPF).
