Suppose you are given the following macroeconomics data (in
million):
Aggregate Demand: ?? = ? + ? + ? + ??
Short-run Aggregate Supply (SRAS): ? = 16,000 + 7,000?
Long-run Aggregate Supply (LRAS): ??? = $74,000
Where,
??? is real GDP at full employment or the natural rate of
unemployment.
? is the aggregate price level.
Consumption spending: ? = ??, ??? + ?. ??? − ????
I = $4,400 G = $2,000 T = $2,000 NX = $1,200
1. Find the equation for the AD curve for this economy.
2. Find the short-run equilibrium level of real GDP (???) and
the aggregate price level (?).
3. Draw a graph representing the AD curve, the SRAS curve, and
the LRAS curve. Provide a brief
comment on this graph.
Suppose you wish to return this economy to its real GDP at
full employment through tax policy.
4. Provide a numerical analysis for this policy.
5. Calculate the value of public saving. Is the government
running budget surplus or budget deficit?
Explain.
6. Given your answer in question 4, provide an equation for
the new Aggregate Demand curve?
7. Explain in words and graphically, what will happen in long
run if government decides to do nothing?
