- Given the Aggregate demand function of US AD= 5000 + 0.7Yd. Interpret this equation and diagramatically express the equilibrium outputIn 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 agregate supply and agregate demand. 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).
- 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).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…Refer to Table 8.9. The equilibrium level of aggregate output is Select one:
- 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?Assume that the long-run aggregate supply curve is vertical at Y = 3.000 while the short-run aggregate supply curve is horizontal at P=1.0, . The aggregate demand curve is Y = 2(M / P) and M = 1,500. Suppose the aggregate demand function shifts to Y = (1.5)(M / P) . What are the short- run values of P and Y? Show the change in short and long- run equilibrium graphically . Describe the short- run and long- run effects of the change in demand .can you expand on the question and provide a demand and supply diagram relating to the topic "disequilibrium"
- The data below represents the price level, the aggregate demand, and the aggregate supply data for an economy. Use the data points to plot an aggregate demand curve and aggregate supply curve for this economy. Each curve is labeled as AS (Aggregate Supply) or AD (Aggregate Demand) and each point is labeled as a, b, or c from the table headings. (Hint: Note that point a from the AD curve is already plotted with the correct coordinates. Plot the remaining points.) Provide your answer below: Price Level -100 200 180 160- 140- 120 AS: a ($140,100) AS: b ($300, 100) AS: c ($500,100) 100- -80 -60 40 20 0 -20 AD: c ($100,80) 100 Price Level Aggregate Supply (AS) Aggregate Demand (AD) 200 AD: b ($300,80) AD: a ($390,80) 300 400 600 500 Real GDP ($) a b 120 80 $320 $420 $390 $340 C 170 $540 $280Suppose that the production function for the economy is given by: Y = AL/3K/3 Suppose that this economy has 1,000 units of Labour, and 125 units of capital, and TFP (A) is equal to 10. The Short-Run Aggregate Supply Curve (AS) here is given by: Y = 5p And when we consider the AEF at a price level of $1,400, the main components of it (C, I, & G) are given by (we are assuming a closed economy NX = 0): C = 300 + 0.8Y I = 300 G = 200 1. What is potential GDP in this question (Y*)? Show your work. Suppose also that for any $10 decrease in price, desired consumption will increase by $5. 2. Write down the equation for the Aggregate Demand Curve (AD) in the form of Y = a + bp. Show your work. 3. What is the current Short-Run Equilibrium value for Real GDP (Y) and the price level (p)? Show your work. 4. Draw the AD, AS, and LRAS curves. Label all x-intercepts and y-intercepts. Are we currently in an Inflationary Gap, Recessionary Gap, or in Long-Run Equilibrium? How do you know?When does macroeconomic equilibrium occur? Multiple Choice When exports equal imports. When the aggregate supply equals the long-run Aggregate Supply When the aggregate demand equals the long-run Aggregate Supply. When the aggregate quantity demanded is equal to the aggregate quantity supplied.
