Deriving Saving Function and Aggregate Demand

  • To calculate the saving function, consider the Marginal Propensity to Consume and Average Propensity to Consume.
  • The saving function can be derived by adding the values of both the A's and M's.
  • The saving function is written in minus due to autonomous consumption.
  • For a given question with 0.8, calculate the Net Propensity to Save (NPS) using the formula 1 - MPC (0.2).
  • Another example involves a consumption formula of 20 + 0.7y to derive the saving function.
  • Consumption plus saving equals income, forming the basis of the chapter.
  • Investment is related to income, with two types: Induced Investment and Autonomous Investment.
  • Autonomous Investment is done by the government even when income is zero for welfare purposes.
  • Aggregate Demand is the total demand of a country, comprising private final consumption expenditure, investment, government final consumption expenditure, and net exports.
  • Aggregate Supply is the total production of a country, with components including consumption.
