Transcribed Image Text:Suppose that the production function for the economy is given by:
Y = AL/3K/3
Suppose that this economy has 1,000 units of Labour, and 125 units of capital, and TFP (A) is
equal to 10.
The Short-Run Aggregate Supply Curve (AS) here is given by:
Y = 5p
And when we consider the AEF at a price level of $1,400, the main components of it (C, I, & G)
are given by (we are assuming a closed economy NX = 0):
C = 300 + 0.8Y
I = 300
G = 200
1. What is potential GDP in this question (Y*)? Show your work.
Suppose also that for any $10 decrease in price, desired consumption will increase by $5.
2. Write down the equation for the Aggregate Demand Curve (AD) in the form of
Y = a + bp. Show your work.
3. What is the current Short-Run Equilibrium value for Real GDP (Y) and the price level (p)?
Show your work.
4. Draw the AD, AS, and LRAS curves. Label all x-intercepts and y-intercepts. Are we
currently in an Inflationary Gap, Recessionary Gap, or in Long-Run Equilibrium? How do
you know?
