- As you know, supply and demand shifts are caused by one of their determinants. Shifts in aggregate demand (AD) show the effect of events on price level and Real GDP. Any event that causes a change in consumer, business, or government spending or any change in net exports (C+l+G+Xn) will shift AD. Any event that causes a change in production costs or increases productivity will shift aggregate supply (AS). Decide if the following events are Micro, shifting supply or demand, or Macro, shifting AD or AS. Give the direction in which the graph shifts. Demand Situation Aggregate Supply Aggregate Demand Supply Sales of Atlanta Braves gear grows with the success of the team. 1. The President and Congress pass a trillion dollar stimulus bill to provide aid during recession. 2. 3. Salmonella outbreak in peanut processing plants threatens lunches for school children. 4. Pomegranates are shown to be cancer fighting superfoods. Value of U.S. dollars declines, exports increase. 5. Global oil prices…Suppose you are given the following information about an economy: Short run Aggregate Supply: SRAS = Y = 5000r+ 14,400 Long run Aggregate Supply: Aggregate Demand: Investment Spending: Consumption Spending: Government Spending: Net Exports (eX – iM): LRAS = Y* = 25,000 AD = Y=C+I+G+NX_ I = 4000 – 250r C = 1000 +0.75(Y – T) G = 2000 NX = 500 Taxes – Transfers: T = 2400 Monetary Policy: Money Demand: Money Market equilibrium: Fisher equation: where i is the nominal interest rate (i.e. when the interest rate is 7%, it means i= 7) r = 2 n м 3 20,000- 2000i M$ = MD i = r+T e. Find the short run equilibrium level of real GDP (Y), and inflation rate (t), in the short run. What is the output gap in the economy? Is it an expansionary or recessionary gap?In the above figure, for a shift from AD1 to AD2, the aggregate demand decreases by 1) 110. 2) 10.4. 3) 0.8. 4) 0.4.
- An economy is described by the following: C=20+0.9Y I=120-200r. Md=250+0.2Y-400r. Ms/P=1250 Y=70 W=17.5 Lf=144 a) Find AS and AD. b) Find the equilibrium level of Y and P c) Graphically represent this economy d) Find the long-run Y of this economy. e) What is the level of government expenses G, the government needs to impose in order to lead the economy to the full employment? (Show the long-run graphically).can you expand on the question and provide a demand and supply diagram relating to the topic "disequilibrium"Based on Aggregate Demand and Aggregate Supply Model, what is the effect on AS of each of the following events (will AS increase and shift to the right or decrease and shift to the left): (A) Decrease in labor force (B) Increase in productivity (C) Increase in capital stock
- Understanding SRAS and LRAS Determine the effect on the short-run aggregate supply (SRAS) curve for each of the following scenarios. Please graphically display # 1-5. Remember to accurately label all lines, points, and axes when drawing the graphs for these exercises. Indications are the same as for the question above, but for the SRAS. Then answer the last two questions regarding the LRAS. 1. Labor productivity increases in the macroeconomy. 2. An earthquake destroys a significant amount of infrastructure in the economy. 3. Technological progress occurs in the economy. Answer the following questions about the LRAS. 4. Why is the LRAS curve vertical? 5. Can the LRAS curve shift?For each situation below, analyse whether it shifts the aggregate demand (AD) curve, the aggregate-supply (AS) curve, both, or neither. Then, if it does shift a curve, construct the AD-AS diagram to show the effect on the economy in the long-run. a) One extraordinary impact of COVID-19 pandemic to the U.S. economy is a massive increase in saving. U.S. recorded nearly tripled saving over the first two quarters of 2020, from $1.59 trillion annualized in the first quarter to $4.69 trillion in the second, which is by far the biggest increase in modern history. b) The prolonged monsoon rain has caused the production of vegetables in Cameron Highlands fell by about 30%. It has severely impacted a lot of crops, including fruits and flowers. Besides, labor shortages due to the pandemic makes the matters worse.The table below shows information on aggregate supply, aggregate demand and the price level for the imaginary country of Xurbia. Price Level AD AS 110 700 600 120 690 640 130 680 680 140 670 720 150 660 740 160 650 760 170 640 770 Plot the AD/AS diagram from the data shown (Don't have to show graph but do draw it to help you answer the questions). a. Identify the equilibrium. b. Imagine that as a result of a government tax cut, aggregate demand becomes higher by 50 at every price level. Identify the new equilibrium. c. How will the new equilibrium alter output? How will it alter the price level? What do you think will happen to employment?
