Economics 3040 Intermediate Macro HW4: An Adverse Demand Shock For all graphs label: both axis, all lines or curves, and all equilibrium values. Also be sure that the direction of shifts in lines and changes in equilibrium values are clear. Your graphs should be large enough to easily interpret. Turn in your graphs on paper at the beginning of the March 26th class meeting. (1) Sketch a graph of the goods market (AD-SRAS-LRAS) and a graph of the labor market with both markets initially in long run equilibrium. Label the initial values of real GDP, the price level, employment, and the nominal wage. Now show the effect of an adverse demand shock on both graphs and label the new values of all variables. (2) Sketch a graph of the goods market initially in a recession. Label potential real GDP, real GDP in the current recession, and the current price level. Also label the recessionary gap. Now show how an increase in government spending may end the recession. (3) Sketch a graph of the goods…
3. The graph below shows the AD-AS model for the US in long-run equilibrium. Label both axes and the following: AD, SRAS, LRAS. Indicate the equilibrium price level is P, and equilibrium level of output is Yo. X Assume that due to an expansion in European economics, US exports to that region increase. A. Show the effects of this change in the graph above. B. What happens to the SR equilibrium price level and level of output (Real GDP)? Label these P₁ and Y₁. C. Initially, what happens to real wages? D. What happens to the unemployment rate? E. Given your answer to parts C and D, how might workers respond? F. Show the effects of the change described in part E in the graph above. Label the new equilibrium price level and level of output as P₂ and Y₂. G. After this transition to the LR equilibrium, what is the level of output (Y₂) as compared to the initial level (Yo)?
Suppose the economy is operating at potential GDP when It experiences an increase in export demand. How might the economy increase production of exports to meet this demand, given that the economy is already at full employment?
On a microeconomic demand curve, a decrease in price causes an increase in quantity demanded because the product in question is now relatively less expensive than substitute products. Explain why aggregate demand does not increase for the same reason in response to a decrease in the aggregate price level. In other words, what causes total spending to increase if it is not because goods are now cheaper?
2. An introduction to the AD-AS model The aggregate demand and aggregate supply model is a useful simplification of the macroeconomy used to explain short-run fluctuations in economic activity around its long-run trend. The vertical axis of a diagram of the aggregate demand and aggregate supply curves measures which of the following? An economy’s price level The amount of a particular representative good produced in the economy The price of a particular representative good produced in the economy Which of the following are reasons that the short-run aggregate supply curve slopes upward? Check all that apply. As the price level rises, firms expand their production because they can sell their output for more money. As the price level rises, firms find it more profitable to hire workers at any given wage. As the price level rises, firms decrease their investment because it is more expensive to purchase capital.
5. An economy is initially in equilibrium, both in the short-run and in the long-run. Using the AD, SRAS, and LRAS curves, show and explain what would happen to the equilibrium aggregate price and output in both the short-run and the long-run if the following scenario occurs. a. Oil production increases significantly as OPEC and non-OPEC countries have agreed to raise their production quota, and the government anticipates the situation by implementing a contractionary fiscal policy. b. COVID 19 pandemic has forced the government to initiate a total lock down.
