### Fiscal Policy & The Multiplier

• The MPC stands for the marginal propensity to consume
• The MPS stands for the marginal propensity to save
• MPS = 1 – MPC
• The multiplier formula = 1/(1-MPC)
• The consumption function, which shows how an individual household’s consumer spending changes with disposable income, is c = a + MPC x yd
• The tax multiplier is (MPC)/(1-MPC)
• Government spending has a greater impact than a tax cut in stimulating the economy because individuals tend to save some of their income
