Figure 8.3 Price Level Long run Aggregate Supply A B AS₁ AS2 AD1 AD2 Quantity of Output Long run Aggregate Supply = Potential GDP Refer to Figure 8.3 above. If the economy is at point A, which of the following would cause a change from AD1 to AD2? An increase in expected future inflation. ○ An increase in expected future profit. ○ A tax cut or an increase in either transfer payments. O An increase in the interest rate or a decrease in the quantity of money.

Assume an economy operates in the intermediaterange of its aggregate supply curve. State thedirection of shift for the aggregate demandor aggregate supply curve for each of thefollowing changes in conditions. What is theeffect on the price level? On real GDP? Onemployment?a. The price of crude oil rises significantly.b. Spending on national defense doubles.c. The costs of imported goods increase.d. An improvement in technology raises laborproductivity.

When the economy is experiencing a recession, why would aneoclassical              e conomist be unlikely toargue for aggressive policy to stimulate aggregate demandand return the economy to full employment? Explain your answer.

Assume an economy operates in the intermediate range of its aggregate supplycurve. For each of the following changes in conditions, state the direction of theeffect on:1. aggregate demand, 2. aggregate supply, 3. price level, and 4. real GDP.

befoe y ee nd My a PRAS P feyr Output Reset In 6-2 we studied how unantioipated infation might affect the supply of goods and services in the economy and construced the shon-un aggregate supply ourve The interactive above shows how the SRAS curve changes at different levels of price fexibility. R is helptu in anowering the tulowing questions According to the SRAS curve, f prices are prefecty fexible O Unexpected changes in the price level wil have a large effect on output. O Unexpected changes in the price level will have no etfect on output O Unexpected changes in tme price level will have some etfect on output O None of these Inflation rate

Theshortrunaggregatesupplycurvewasconstructedassumingthatasthepriceofoutputsincreases,thepriceof inputs stays the same. How would an increase in the prices of important inputs, like energy, affect aggregate supply?

Which of the following will NOT shift the AD curve? O a. Changes in consumer confidence O b. Changes in autonomous exports O c. Changes in government expenditure O d. Changes in the inflation rate ?

In the diagram, the economy has Aggregate price level LRAS SRAS, P, Aggregate Demand Yp Y, Real GDP An inflationary gap, so in the long run wages will fall, causing AD curve ti shift to the left. An inflationary gap, so in the long run wages will rise, causing the SRAS curve to shift to the left. O A recessionary gap, so in the long run wages will fall, causing the AD curve to shift to the left. O A recessionary gap, so in the long run wages will fall, causing the SRAS curve to shift to the right.

1) aggregate demnad and aggregate supply in market     a) using an ad-as diagram, explain what happens if personal income taxes increases     b) explain what will happen to an ad-as diagram, if there is a decrease in input prices     c) explain the changes in wages can affect equilibrium

1. Which of the following could cause a shift from AD to AD₁, ceteris paribus? PRICE LEVEL a a Figure 10.1 REAL OUTPUT ($ billions per year) B) an increase in exports A) a decrease in investment AD OC) an increase in consumer confidence OD) an increase in consumption AS 4
