The amount by which the aggregate expenditures schedule must shift downward to decrease the nominal GDP to its full-employment noninflationary level.
Define the Economic word/phrase "Full Employment GDP Level".
The use of all available resources to produce want-satisfying goods and services.
When the unemployment rate is equal to the full unemployment rate the situation is called?
Full Employment GDP Level.

An economy that has closed international training, and no government spending.
What is a open mixed economy?
An economy that has open international trading and government spending.
The 45° line on a graph relating consumption and income shows:
All the points at which consumption and income are equal.
If Bob's MPC is .60, that means that he will:
Spend 6/10's of any increase in his disposable income.
In the late 1990's the U.S. stock market boomed, causing U.S. consumption to rise. This is an example of what kind of effect?
When consumption and saving are graphed relative to real GDP, an increase in personal taxes will shift:
Both the consumption and saving schedules downward.
Other things equal, a decrease in the real interest rate will:
Move the economy downward along its existing investment demand curve.
Assume a machine which has a useful life of only 1 year costs $2,500. Assume also that the additional revenue from the output of this machine is expected to be $3,650. What is the expected rate of return?
The relationship between the real interest rate and investment is shown by the:
Investment demand schedule.
The investment demand curve suggests:
There is an inverse relationship between the real rate of interest and the level of investment spending.
Other things equal, a 10% decrease in corporate income taxes will:
Shift the investment-demand curve to the right.
Other things equal, a 25% increase in corporate income taxes will:
Shift the investment-demand curve to the left.
The investment demand curve will shift to the right as the result of:
Businesses becoming more optimistic about future business conditions.
If the real interest rate in the economy is " i " and the expected rate of return form additional investment is " r ", then more investment will be forthcoming when:
" r " is greater than " i ".
The practical significance of the multiplier is that it:
Magnifies initial changes in spending into larger changes in GDP.
John Maynard Keynes created the aggregate expenditures model based primarily on what historical event?
The Great Depression.
In the U.S. from 1929 to 1933, what was the real GDP and the unemployment rate?
real GDP declined 27%, unemployment rose 25%
All else equal, a large decline in the real interest rate will shift the :
Investment schedule upward.
The level of aggregate expenditures in the private closed economy is determined by the:
Expenditures of consumers and businesses.
In a private closed economy, when aggregate expenditures equal GDP:
Planned investment equals saving.
In a private closed economy, when aggregate expenditures exceed GDP:
Business inventories will fall.
If an unintended increase in business inventories occurs:
We can expect businesses to lower the level of production.
If unintended increases in business inventories occur, we can expect:
A decline in GDP and rising unemployment.
If the equilibrium level of GDP in a private open economy is $1000 billion and consumption is $700 billion at that level of GDP, then:
Ig and Xn must equal $300 billion.
Suppose income is $2000, and consumption is $1950 in year 1. In year 2 income rises to $3000 and consumption $2700. What is the MPS?
Suppose income is $2000, and consumption is $1950 in year 1. In year 2 income rises to $3000 and consumption $2700. What is the multiplier?
If MPC = .5, current GDP = 6Trill 900 Bil, and Ig decreases 70Bil, what is the additional investment component?
If MPC = .5, current GDP = 6Trill 900 Bil, and Ig decreases 70Bil, what is the new level of GDP/Output?
6Trill 760 Bill
If MPC = .8,
AE = $500 Bill, C = $200 Bill, Ig = $100 Bill, and Nx = $50 Bill
What is the multiplier?
What is Aggregate Demand?
A schedule or curve that shows the amounts of real output that buyers collectively desire to purchase at each possible price level.
What is Aggregate Supply?
A schedule or curve showing the relationship between the price level and the amount of real domestic output that firms in the economy produce.
What are 3 important features of the Aggregate Demand - Aggregate Supply model?
Inflation, recession, unemployment.
What are the 4 sub-categories of consumer spending?
Consumer wealth, expects, household borrowing, taxes.
What are the 2 sub-categories in net export spending?
National Income abroad and money exchange rates.
What are the determinants of Aggregate Demand?
Consumer spending, investment spending, government spending, net export spending.
What are the 2 sub-categories of input/resource prices?
Domestic resource prices and prices of imported resources.
What are the 2 sub-categories of legal-institutional environment?
Business taxes and subsidies and government regulation.
What are the 3 time Horizons involved with Aggregate Supply?
Immediate short run, short run, and long run.
What are the 3 determinants of Aggregate Supply?
Input/Resource prices, Productivity, Legal-Institutional, and Environment.
Other things equal, if the national incomes of the major trading partners of the U.S. were to rise, the U.S.'s:
Aggregate demand curve would shift to the right.
If investment decreases by $20 billion and the economy's MPC is .5, the aggregate demand curve will shift:
Leftward by $40 billion at each price level.
An economy's aggregate demand curve shifts leftward or rightward by more than changes in initial spending because of what effect?
In an effort avoid recession, the government implements a tax rebate program, effectively cutting taxes for households. We would expect this to:
Increase aggregate demand.
The aggregate supply curve shows:
Various amounts of real output that businesses will produce at each price level.
The aggregate supply curve (short-run) is up sloping because:
wages and other resource prices match changes in the price level.
Other things equal, and improvement in productivity will shift:
The aggregate supply curve to the right.
Other things equal, if the U.S. dollar were to depreciate the:
Aggregate demand curve would shift to the left.
What would increase the per unit production cost and shift the aggregate supply curve to the left?
An increase in the price of imported resources.
Other things equal, a reduction impersonal and business taxes can be expected to:
Increase both aggregate demand and aggregate supply.
