Unit 3: Aggregate Supply and Demand Quiz
Change in Net Exports (X-M)
Exchange Rates (If the U.S. dollar depreciates relative to the euro...) National Income Compared to Abroad (If a major importer has a recession...) (If the U.S. has a recession...)
Foreign Trade Effect
When U.S. price level rises, foreign buyers purchase fewer U.S. goods and Americans buy more foreign goods. Exports fall and imports rise causing real GDP demanded to fall. (Xn Decreases) For example: If prices triple in the U.S. Canada will no longer buy U.S. goods causing quantity demanded of U.S. products to fall. So: price level increases, GDP demanded decreases
Aggregate Demand
all goods and services (real GDP) that buyers are willing and able to purchase at different price levels. The demand for everything by everyone in the U.S.
When we use aggregates, we combine
all prices and all quantities
Price level increases, Price level decreases
real GDP demanded decreases, real GDP demanded increases
An increase in spending shifts AD to the _______, and decrease in spending shifts AD to the _______
right, left
If consumer spending decreases, what will happen in the long-run
wages and costs decrease (opposite for short-run)
If consumer spending increases, what will happen in the long-run?
wages and costs increase (opposite for short-run)
If producers expect higher prices in the future, workers will demand higher _______ and _______ to increase. This will _______ AS
wages, costs, decrease
AS is the production of all _______ in the economy
firms
Aggregate Supply
the amount of goods and services (real GDP) that firms will produce in an economy at different price levels. The supply for everything by all firms.
Aggregate Demand is
the demand by consumers, businesses, investments, and foreign countries
Aggregate
"added all together"
Change in Government Spending
(Decrease in defense spending...) (Increase in public works programs...)
AD =
C + I + G + Xn
AD = GDP =
C + I + G + Xn
R.A.P.
Change in: Resource Prices, Actions of Government, and Productivity
What doesn't shift the AD Curve?
Changes in price level, which causes a moves along the curve
In a Recessionary Gap, Actual GDP is below potential _______
GDP
The Wealth Effect
Higher prices levels reduce the purchasing power of money. This decreases the quantity of expenditures. Lower price levels increase. For example: If the price level doubles, people are going to buy less stuff because they have less purchasing power. So: price level increases, GDP demanded decreases
Short-Run AS Example
If a firm currently makes 100 units that are sold for $1 each. The only cost is $80 of labor. How much is profit? $100 - $80 = $20. What happens in the SHORT-RUN if price level doubles? Now 100 units set for $2, $200 - $80 = $120 profit. With higher profits, the firm has incentive to increase production
Long-Run AS Example
If a firm has a Total Revenue of $100 and uses $80 of labor, profit is $20. What happens in the LONG-RUN if price level doubles? TR $200 - IN the LONG RUN, workers demand higher wages to match price. So labor costs double to $160. If REAL profit doesn't change the firm has no incentive to increase output (production)
Change in Consumer Spending
Increase in Disposable Income (Higher incomes...), Consumer Expectations (People fear a recession...), Household indebtedness (More consumer debt...), Taxes (Decrease in income taxes...)
Capital Stock
Machinery and tools purchased by business that increase their output
If an increase in consumption or government spending doesn't cause economic growth, what does?
Only investment cases growth since firms increase their capital stock
Inflationary Gap
Output is high and unemployment is less than NRU
Recessionary Gap
Output is low and unemployment is more than NRU
The _______ shifts outward since producers can make more
PPC
Change In Resource Prices
Prices of domestic and imported resources (increase in price of Canadian lumber...) (Decrease in price of Chinese steel) Supply Shocks (Negative Supply Shock...) (Positive Supply Shock...) Inflammatory Expectations (If people expect higher prices in the future...)
Change in Investment Spending
Real Interest Rates (Price of borrowing $) Future Business Expectations (High Expectations...) Productivity and Technology (New robots...) Business Taxes (Higher corporate taxes means...)
The economy can be in 1 of 3 places at a time:
Recessionary Gap, Full Employment, or Inflationary Gap
Aggregate Supply differentiates between _______ and _______, which have two different curves
Short-Run, Long-Run
Change in Actions of Government (NOT Government Spending)
Taxes on producers (Lower corporate taxes...) Subsidies for Domestic Producers (Lower subsidies for domestic farmers...) Government Regulation (EPA inspections required to operate a farm...)
Change in Productivity
Technology (Computer virus that destroys half the computers...) (The advent of a teleportation machine...)
Long-Run Aggregate Supply (Vertical supply curve)
Wages and Resource prices will increase as price levels increase
Short-Run Aggregate Supply (Normal looking supply curve)
Wages and Resource prices will not increase as price levels increase
Interest Rate Effect
When the prices level increases, lenders need to charge higher interest rates to get a REAL return on their loans. Higher interest rates discourage consumer spending and business investment. For example: An increase in prices leads to an increase in the interest rate from 5% to 25%. You are less likely to take out loans to improve your business. So: price level decreases, GDP demanded increases.
Use the AD and AS model to show an economy at full _______ output
employment
In an Inflation Gap, Actual GDP is above our _______
potential
Inverse
the relationship between price level and real GDP
