  1. Marginal Propensity to Consume • The increase in consumer spending when disposable income rises by $1. • Disposable income is the money one has after paying taxes (the money one has to live on).

  2. Marginal Propensity to Save • The increase in household savings when disposable income rises by $1

  3. Autonomous Change In Aggregate Spending • An initial rise or fall in aggregate spending that is the cause, not the result, of a series of income and spending changes. • (autonomous means “self-governing”)

  4. The Multiplier • The multiplier shows how initial changes in spending lead to further changes. • The ratio of the total change in real GDP caused by an autonomous change in Aggregate Spending to the size of that autonomous change

  5. The Multiplier • The federal government recently enacted the American Recovery and Reinvestment Act of 2009. • This “stimulus package” of $787 billion was intended to spark job growth to reverse the worst recession since the Great Depression. • How was this supposed to work?

  6. The Multiplier • The short answer is that $1 of spending in one area of the economy multiplies into more than $1 of spending throughout the economy.

  7. The Marginal Propensity to Consume • Consumption is a huge fraction (more than 2/3) of total spending in the economy. • After a person pays his taxes, he is left with disposable income (Yd) that can either be consumed or saved. • Yd = C + S

  8. The Marginal Propensity to Consume • When a person gets more disposable income, Yd, he will increase both C and S. • The marginal propensity to consume (MPC) = change in consumption/change in disposable income. • The marginal propensity to save MPS = Change in Saving/Change in Disposable Income • MPC + MPS = 1

  9. The Consumption Function • The Consumption Function is an equation showing how an individual household’s consumer spending varies with the household’s current disposable income.
