Multiplier and accelerator Flashcards

K = 1 / 1 - MPC
or
K = increase in national incomes / increase in spending
Marginal propensity to consume (MPC)
The fraction of a rise in disposable income spent on goods and services.
Factors affecting the value of a multiplier
1 = MPC + MPT (tax) + MPM (imports) + MPS (saving)
Elasticity of supply on real GDP
