Learning Objectives

Indicator: 2.4.1.LI.1 - Calculate National Income by using any of the three approaches.

By the end of the lesson, learners can:

  1. Define National Income and distinguish between the product, income, and expenditure approaches to measuring it.
  2. Calculate National Income using the product (output) approach by summing the value added at each stage of production.
  3. Calculate National Income using the income approach by summing wages, rents, interest, and profits.
  4. Calculate National Income using the expenditure approach by summing consumption, investment, government spending, and net exports (C + I + G + (X - M)).
  5. Reconcile the results from the three approaches and explain why they should theoretically yield the same total.
