CHAPTER 30 THE MULTIPLIER Flashcards
Marginal propensity to import (MPM)
The increase in imports divided by the increase in income that caused them
Marginal propensity to save (MPS)
The increase in saving divided by the increase in income that caused them
Marginal propensity to tax (MPT)
The increase in tax revenues divided by the increase in income that caused them.
Marginal propensity to withdraw (MPW)
The increase in withdraw from the circular flow (S+T+M) divided by the increase in income that caused them; this is the same as the sum of the marginal propensity to save, tax and import (MPS+MPT+MPM)
Multiplier or national income multiplier or Keynesian multiplier or real multiplier.
The figure used to multiply a change in an injection into the circular flow, such as investment, to find the final change in income (assuming the injection is not determined by income). It is the ratio of the final change in income to the initial change in an injection.
Multiplier effect or process
An increase ion investment or other injection will lead to and even greater increase in income (assuming the injection is not determined by income)
