Class Recap

• Brief overview of the previous lessons, focusing on the Production Possibility Curve (PPC).

Understanding Production Possibility Curve (PPC)

• The PPC represents the maximum combinations of two goods that an economy can produce given its resources.

• Key Concept: A combination is productively inefficient if it lies below the PPC, indicating that more of one good can be produced without sacrificing the other.

Example of Shoemaking Economy

• Example: If Atlantis produces 20,000 pairs of shoes, it can still produce up to 70,000 tons of corn.

• Combination (20,000 shoes, 70,000 corn) is attainable.

• The economy has adequate resources, confirming this combination is feasible.

Productive Inefficiency

• Understanding how much more of one good can be produced without giving up the other is crucial.

• Question: "How much more could it produce without giving up any corn/shoes?" This refers to productive inefficiency.

Identifying Productive Inefficiency

• Example Scenario: For a combination of 40,000 tons of corn and 40,000 pairs of shoes:

  • Lies below the PPC.

  • Indicates that it is possible to produce more shoes without cutting back on corn.

  • Can offer 20,000 more pairs of shoes without reducing corn production.

Calculation Method

• Teachers favor schedule methods for answering PPC-related questions:

  1. Identify the current combination from the schedule.

  2. Indicate how much more of each product can be produced without impacting the other.

  3. Present the findings clearly through calculations (subtraction).

Opportunity Cost Analysis

• Analyzing Opportunity Cost:

  • For question calculations (e.g., 100 iPods at 400 ThinkPads), students must show their work clearly.

  • Example Calculation: If producing an additional 20 ThinkPads costs 50 iPods:

    • Opportunity cost of 20 ThinkPads is 50 iPods.

    • Dividing correctly will show the conversion and opportunity cost accurately.

Reminder on Exams

• The instructor will provide specifics about upcoming tests, including topics and format.

• Students are encouraged to review all materials and practice calculations to prepare.
