Consider a fictional economy that is operating at its long-run equilibrium. The following graph shows the aggregate demand (AD) curve and short-run aggregate supply (AS) curve for the economy. The long-run aggregate supply curve is represented by a vertical line at the potential GDP level of $6 trillion. The economy is initially producing at potential GDP. Suppose that fiscal authorities decide to decrease marginal tax rates. Assume that this change in marginal tax rates is perceived as a long-term change. Shift the appropriate curves to illustrate the supply-side view of the fiscal policy effect on output and the price level. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther. 120 Potential GDP AS 100 PRICE LEVEL 60 80 60 40 40 20 20 0 0 2 4 6 8 AD 10 12 QUANTITY OF OUTPUT (Trillions of dollars) AD 1 AS Potential GDP True or…
If the intersection of AD and SRAS occurs at $21 trillion GDP but full employment GDP (LRAS) is at $22 trillion GDP, which of the following policy choices would help move the economy toward full employment? a) Lowering income taxes and payroll taxes for all employees. b) All of the choices would help increase AD and bring the economy closer to full employment. c) increasing the money supply to lower interest rates. d) Increases government spending on infrastructure. e) Sending out stimulus checks to everyone earning less than $100,000 per year.
The following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $300 billion. Suppose households suddenly begin to spend less and save more in order to increase saving for retirement. Shift the short-run aggregate supply (AS) curve or the aggregate demand (AD) curve to show the short-run impact of the sharp increase in saving. PRICE LEVEL 240 200 160 120 8 40 0 0 100 200 300 400 OUTPUT (Billions of dollars) AS AD 500 600 AD AS A In the short run, the decrease in consumption spending associated with the increase in saving causes the price level to price level people expected and the quantity of output to the unemployment rate to the the natural level of output. The sharp increase in saving will cause the natural rate of unemployment in the short run.
An economy's AD curve is P=19-0.2Y and its AS curve is P-1.5+0.05Y. Suppose that autonomous expenditure increases by two such that the AD curve is changed to P=21-0.2Y. What is the value of the multiplier that allows for price increases? The answer is 4. please provide explanation in detail.
On the following graph, show the effect of the change in investment demand on the AD curve once the multiplier process has run its course. Use the green curve (triangle symbol) to plot the new AD curve at price levels of 40 and 140. Hint: Use the new quantity of investment demanded you found in the Market for Investment and the multiplier to determine the exact change in aggregate demand at both price levels. Assume that this effect is independent of the price level, that is, the AD curve has a parallel shift. An expansionary monetary policy causes the quantity of bank reserves in the economy to ________(INCREASE/DECREASE) , which drives interest rates _______ (UP / DOWN) . As a result, businesses invest______(MORE/LESS) in capital improvements such as new factories and equipment. This leads to ________(AN INCREASE. A DECERASE) in aggregate demand, the extent of which is determined by the simple spending multiplier.
Instructions: Enter your responses as a whole number. Identify the macro equilibrium. Instructions: Use the tool provided 'QE' to identify the current macro equilibrium on the graph. The current macro equilibrium is when real GDP is $ billion. Suppose that full - employment GDP is $12 billion. The real GDP gap is $ billion. Aggregate demand must shift (left or right) by $ billion to achieve the full - employment equilibrium.Real GDP (in billions of dollars per year)
In the 1960s the U.S entered the Vietnam War, and military expenditures (part of government expenditures) grew from an annual rate of $113 billion to 138 billion. The economy was near full-employment and, therefore, given there was no offsetting tax increase, inflation pressures emerged. Assume the MPC is .75 A) How did the increase in military expenditures affect AD? B) If in 1968 the AD Excess was $150 billion, what change in government expenditures would you have recommended?
If investment increases by 24 billion and the economy's MPC is 0 0.5, the aggregate demand curve will shift rightward by _____ billion dollars at each price level.
d. Now G assumes its original value of G = 800. Congress decreases the tax rate from (1/2) to (1/4). i) Use a model to sketch the effect of the decrease in the tax rate when the price level is held constant. ii) What is the new marginal propensity to consume? iii) Calculate the new equilibrium level of income.
At an intial point on the aggregate demand curve, the price level is 100, the real GDP is $18 trillion. After the price level rises to 110, however there is an upward movement along the aggregate demand curve, and real GDP declines to $14 trillion. If total planned spending declines by $200 billion in response to the increase in the price level, what is the MPC in this economy?
Consider a closed economy with no government, where aggregate demand is determined by autonomous consumption, investment (which is independent of output), and the marginal propensity to consume. a) Given that autonomous consumption is 20, investment is also 20, and the marginal propensity to consume is 0.6, write out an equation for aggregate demand (AD) in this economy. b) Given this aggregate demand equation, and the equilibrium equation Y = AD, use algebra to find the equilibrium level of Y. (2 marks) c) Draw a diagram with output (Y) on the x-axis and aggregate demand (AD) on the yaxis. Draw two lines on this diagram: (i) Y = AD, and (ii) the aggregate demand function from part (a). Label the intercept of the AD line, and the point where the two lines intersect, with numerical values. d) Suppose that the marginal propensity to consume falls from 0.6 to 0.5. What would the new equilibrium level of Y be? Illustrate your answer in the diagram you drew for part (c). e)…
The graph below shows a 45°-line (Keynesian cross) diagram. The economy is currently in macroeconomic equilibrium at output level Yo. Suppose that investment increases. 1) Use the line tool to show a possible position for the new aggregate expenditures line. Label this line AE2. Note: if you are not prompted for a label, you have used the wrong drawing tool. 2) Use the point drawing tool to show the new equilibrium levels of GDP and expenditures.Label this point 'B'.
