Define and explain each concept and give specific examples: a. Marginal Propensity to Consume and Marginal Propensity to Save ( /5) b. The Multiplier Effect and Spending Multiplier ( /5) c. Deficit Spending and Crowding Out ( /5)

The marginal propensity to save (MPS) is the portion of each extra dollar of a household's income that's saved. MPC is the portion of each extra dollar of a household's income that is consumed or spent. Consumer behavior concerning saving or spending has a very significant impact on the economy as a whole.

Multiplier Effect

for every dollar the government spends, it will create a greater than one dollar change in GDP

Spending Multiplier

1 / 1-MPC or 1 / MPS; increase in spending .: + multiplier; decrease in spending .: - multiplier

Deficit spending is the amount by which spending exceeds revenue over a particular period of time, also called simply deficit.

Crowding out in businesses an economic concept that describes a situation where personal consumption of goods and services and investments by business are reduced because of increases in government spending and deficit financing sucking up available financial resources and raising interest rates.

Explanation: Marginal Propensity to Consume

the fraction of any change in disposable income that is consumed; MPC = change in C / change in DI

Marginal Propensity to Save

the fraction of any change in disposable income that is saved; MPS = change is S / change in DI
