Assume that (a) the price level is flexible upward but not downward and (b) the economy is currently operating at its full-employment output. Other things equal, how will each of the following affect the equilibrium price level and equilibrium level of real output in the short run?a. An increase in aggregate demand.b. A decrease in aggregate supply, with no change in aggregate demand.c. Equal increases in aggregate demand and aggregate supply.d. A decrease in aggregate demand.e. An increase in aggregate demand that exceeds an increase in aggregate supply.
See below. These are true or false questions. 1). In the long-run, aggregate supply is a horizontal line at the long-run price level people can afford. 2). One reason for why the aggregate demand curve slopes down is the wealth effect, which means that a higher price level leads to lower real wealth and, thereby, reduces the level of consumption.
Consider a closed economy, where wages are sticky in the short run. The consumption function isC = c0 + c1(Y − T ), where the marginal propensity to consume c1 is equal to 0.75. Initially the economy is in equilibrium at Y = Y* and P = P e, where P e is the price level that was expected when agents agreed their fixed nominal wage contracts. The short-run aggregate supply curve (SRAS) is horizontal. Suddenly the government increases government spending G by $500. 1. By how much will output Y change (compared to its initial level before the change in G) in the long run, after wage contracts are renegotiated? 2. By how much will consumption C change (compared to its initial level before the change in G) in the long run, after wage contracts are renegotiated? 3. By how much will investment I change (compared to its initial level before the change in G) in the long run, after wage contracts are renegotiated?
2.1. In Figure 2 above, what are the factors that may cause the aggregate demand to shift from AD to AD1? What is the difference between demand pull inflation, cost push inflation and recession? 2.2. In macroeconomics, the immediate short run is known as a length of time when both input prices and output prices are fixed. In the short-run, input prices are fixed but output prices are variable. In the long run, input prices and output prices can vary. Describe the AS curve in the Immediate Short run. Describe the AS curve in the Short run. Describe the AS in the Long run.

Suppose the full-employment level of real output ( Q) for a hypothetical economy is $250 and the price level (P ) initially is 100. Use the short-run aggregate supply schedules below to answer the questions that follow: a. What will be the level of real output in the short run if the price level unexpectedly rises from 100 to 125 because of an increase in aggregate demand? What if the price level unexpectedly falls from 100 to 75 because of a decrease in aggregate demand? Explain each situation, using figures from the table.b. What will be the level of real output in the long run when the price level rises from 100 to 125? When it falls from 100 to 75? Explain each situation.c. Show the circumstances described in parts a and b on graph paper, and derive the long-run aggregate supply curve.
Distinguish between a movement along the aggregate supply curve and a shift of the entire aggregate supply curve. What factors cause each to occur? Please include in your answer the COVID-19 impact in the economy.
Aggregate demand and aggregate supply, based on a problem from “Principles of Economics” by N. Gregory Mankiw a) List the components of country’s GDP in an open economy. For each component, provide an example of an event that would cause a shift of the aggregate demand curve to the right.b) What will be the effect of such events on the level of prices and the real outcome in the short run? Provide a graph.c) What will be the effect of such events on the level of prices and the real outcome in the longrun? Update your graph
The United Kingdom’s economy is in short-run equilibrium with an output level at less than full employment. Using a correctly labeled aggregate demand and aggregate supply graph, show the following: Full employment output, labeled as Yf Equilibrium real output and price level, labeled as YE and PLE Assume that the UK government decreases domestic military expenditures. On the graph from question 1, show how the decreased military expenditures affect the following in the short run: Aggregate Demand Equilibrium real output and price level, labeled as Y2 and PL2. Is the UK government making a good decision in question 2? Why or why not? Explain using your good economic thinking skills!
The following graph shows the economy in long-run equilibrium at the expected price level of 5 and potential output of $5 trillion. Assume a boom increases household wealth and causes consumers to spend more. Using the following exhibit, shift the short-run aggregate supply (SRAS) curve or the aggregate demand (AD) curve to show the short-run impact of the boom. In the short run, the increase in consumption spending associated with the expansion shifts the curve to the , causing the price level to the price level people expected and the quantity of output to potential output. The boom will cause the unemployment rate to the natural rate of unemployment in the short run. Again, the following graph shows the economy in long-run equilibrium at the expected price level of 5 and potential output of $5 trillion before the increase in consumption spending associated with the expansion. Now, on the following exhibit, show the long-run impact of the boom by shifting…
Suppose the economu is operating at less than full employment. an increase in aggregate demand will result in: A. An increase in the general price level and perhaps an increase in the general price level B. A decrease in the general price level and perhaps a decrease in aggregate demand C. An increase in aggregate output and perhaps a decrease in the general price level D. An increase in the general price level and perhaps a decrease in aggregate output
Suppose the aggregate demand (AD) and short-run aggregate supply (AS) schedules for an economy whose potential GDP (LRAS) equals to $2,700 are given by the table. State the short-run equilibrium price level and real GDP. According to the macroeconomic perspectives, is there an inflationary or a recessionary gap? If so, how much is the output gap?
