Question 1

  1. Assume a simple two sector model where Y = C + IC = a + bY and I = Io. Assume in addition, that a = 85, b = 0.45 and Io =55. Calculate the equilibrium level of income.
  2. Assume that:

C =178+0.6Y

I = 240 – 300i

MS = 550

MDT = 0.2Y

MDS = 480 – 500i

Determine the market equilibrium
