Refer to the sets of the aggregate demand, short-run aggregate supply, and long-run aggregate supply curves. Use the graphs to explain the process and steps by which each of the following economic scenarios will shift the economy from one long-run macroeconomic equilibrium to another equilibrium. Under each scenario, elaborate the short-run and long-run effects of the shifts in the aggregate demand and aggregate supply curves on the aggregate price level and aggregate output (real GDP). Suppose the household wealth decreases due to a decline in the stock market asset prices (See the set of graphs below and pay attention to the 3-stage shifts in graphs).

Answer:
In graph one the decline in the stock market asset price causes the AD line to shift downward, decreasing. The long-run equilibrium in the first graph is the point where all three of the lines (LRAS, S1, and D1) are connecting. With a lower GDP, the aggregated demand curve shifts to the left (D1 to D2) creating a new equilibrium point at a lower price level. In the second graph it shows a higher supply with the increase in the SRAS (S1 to S2) curve. It will create a new long run equilibrium at a lower price level. In the last graph it shows both the shift in the AS curve from AD1 to AD2 due to the decrease and it shows the increase in the SRAS curve from S1 to S2 due to higher supplies. It shows both the old and new equilibrium along the LRAS curve. The first one being higher than the other when the shifts to the curves happened it caused the equilibrium to shift down the LRAS curve because of the lower price level. Therefore, there is a wealth decrease due to a decline in the stock market asset price causes the lines to shift causing the price level to lower and the output to increase. b. Assume the government lowers taxes, which increases the household’s disposable income. However, the government purchases (spending) remains the same. (See the set of graphs below and...
