Answer:
Step-by-step explanation:
arithmetic average growth rate = {[(1.33 - 1.25)/1.25] + [(1.40 - 1.33)/1.33] + [(1.51 - 1.40)/1.40] + [(1.59 - 1.51)/1.51]} / 4 = {0.064 + 0.053 + 0.079 + 0.053} / 4 = 0.06225 x 100 = 6.225%
geometric growth rate = ⁴√{0.064 x 0.053 x 0.079 x 0.053} = 0.061%
a) using arithmetic average growth rate
Div₁ = $1.59 x 1.06225 = $1.689
P₀ = $40
g = 6.225%
40 = 1.689 / (Re - 0.06225)
Re - 0.06225 = 1.689 / 40 = 0.04222
Re = 0.04222 + 0.06225 = 0.10447 = 10.45%
b) using geometric average growth rate
Div₁ = $1.59 x 1.061 = $1.68699
P₀ = $40
g = 0.061%
40 = 1.68699 / (Re - 0.061)
Re - 0.061 = 1.68699 / 40 = 0.04217
Re = 0.04217 + 0.061 = 0.103174 = 10.32%
