Document Summary

Ch 10 - solutions to supplemental notes and exercises #1. Keynesian cross & the construction of the is curve. Suppose c0 = 100, c1 = 0. 6, i0 = 500, i1 = 50, and t0 = g0 = 500. E = [ c0 + i0 + g0 - c1t0 ] + c1y - i1(cid:1)r. When r = 4 (percent), e = 600 + 0. 6y. Equilibrium, y = e, implies y = 600 + 0. 6y. When r = 6 (percent), e = 500 + 0. 6y. Equilibrium, y = e, implies y = 500 + 0. 6y. If c1 is decreased to c1 = 0. 5, then. When r = 4 (percent), e = 650 + 0. 5y. Equilibrium, y = e, implies y = 650 + 0. 5y. Note, here the is multipliers are: y/ g = 1/[1 - c1] = 2. 5 = y/ c0 = y/ i0. Y/ t = - c1/[1 - c1] = - 1. 5.
