Ch. 11- Aggregate Expenditure Flashcards
What are some effects of depressions and recessions
> Workers lose jobs
Machines are idle
Inventories accumulate
Output falls sharply
Aggregate Expenditure (Y)
Divided into four primary components of spending: consumption (C), investment (I), government spending (G), and net exports (NX).
Y=C+I+G+NX
What are the 4 factors that affect consumption?
> Current Income (Increases C)
Wealth (Increases C)
Expected Future Income (Increases C)
Interest Rate (Decreases C)
What are the 3 factors that affect investment?
> Expected Profitability (Increases I)
Interest Rate (Decreases I)
Business Taxes (Decreases I)
What determines the government spending component of aggregate expenditure?
Transfer payments are negatively correlated with aggregate income
What are the 5 factors that affect net exports?
>Domestic Income (Decreases NX) >Foreign Income (Increases NX) >Real Exchange Rate (Decreases NX) >Tastes for Foreign Goods (Decreases NX) >Trade Policies (Can increase or decrease NX depending on the policy)
Autonomous Expenditure
Expenditure that is not affected by current levels of income in the economy
What did John Maynard Keynes believe caused the Great Depression?
Insufficient Spending
Planned Investment
The amount firms actively decide to put into resources and inventory. Can differ from actual investment as changes in aggregate demand affect inventory accumulation (excess inventory)
Actual Investment
The amount of new capital investment and actual inventory changes. Unexpected changes in aggregate demand can cause actual inventories to be higher or lower than expected.
Unexpected Slackness in Demand
Difference between planned and actual inventories
Planned Aggregate Expenditure (PAE)
The aggregate expenditure level that consists of consumption, planned investment, government spending, and net exports — into two parts:
>Part dependent on income
>Part dependent on all other factors (real interest rates, wealth, and taxes)
When does Keynesian Equilibrium occur?
When PAE = Actual Aggregate Expenditure
Recessionary Gap
Occurs when equilibrium aggregate expenditure is below the level needed for full employment
Inflationary Gap
Occurs when equilibrium aggregate expenditure is above the level needed for full employment.
