Opportunity Cost and Cost-Benefit Analysis Notes

Opportunity Cost and Cost-Benefit Analysis

Learning Intentions

  • Explain opportunity cost and trade-offs.
  • Evaluate costs and benefits of decisions.

Success Criteria

  • Identify and explain opportunity cost and trade-offs in economic decision-making.
  • Conduct a cost-benefit analysis to aid decision-making.

Key Terms

  • Opportunity cost
  • Cost-benefit analysis
  • Trade-off

Opportunity Cost

  • Relative scarcity requires choices about scarce resources.
  • Economic decisions incur an opportunity cost.
  • Opportunity cost is the value of the next best alternative use of resources.
  • It highlights that an alternative want is unsatisfied when a resource is used for something else.

Visual Representation

  • Opportunity Cost = Next best alternative foregone
  • Example: Studying extra hours means foregoing leisure time.

Values and Economic Decision-Making

  • Values influence choices.
  • Consumers, producers, unions, industry groups, and governments have diverse values.
  • These values affect economic decision-making.

Cost-Benefit Analysis

  • Involves listing costs (including opportunity costs) and benefits of alternatives.
  • Compares costs and benefits to reach a conclusion.

Steps Involved in Cost-Benefit Analysis

  1. Identify all affected groups.
  2. Assess all costs, including monetary value for non-monetary costs (e.g., loss of space).
  3. Assess all benefits, including monetary value for non-monetary benefits (e.g., reduced traffic).
  4. Consider future costs and benefits.
  5. Calculate total benefit and total cost, determining if there's a net benefit.
  6. Choose the option with the greatest net benefit when comparing two options.

Review Questions

  1. Write a definition of opportunity cost.
  2. Opportunity cost example with Zara choosing movies over work.
  3. Opportunity cost example choosing between tennis, homework, or going to a cafe.
  4. Explain why it is important to conduct a cost benefit analysis when making important economic decisions.

Consider Your Own Values

  • Consumer scenario: Holiday in Broome vs. Bali.
  • Producer scenario: Sustainably caught vs. imported prawns.
  • Reflect on the values influencing these decisions.

Compare Costs and Benefits

  • How do total costs and benefits compare?
  • Are there non-quantifiable yet important benefits/costs?

Assess the Risks and Uncertainties

  • What potential risks or uncertainties might affect your decision? How likely are these risks to occur?
  • How would changes in external factors impact the costs or benefits of this decision?

Make the Decision

  • Based on the cost-benefit analysis, what is the best decision to make? Why?
  • If the benefits significantly outweigh the costs, what factors would influence you to reconsider the decision, if any?
