Answer:
a. Calculation of the firm's cost of equity using CAPM
Required rate of return (Cost of equity) = Risk free rate + Beta*Market risk premium
Cost of equity = 2.80% + 1.32*14%
Cost of equity = 2.80% + 18.38%
Cost of equity = 21.28%
b) Calculation of the cost of equity using constant growth model:
Cost of equity = Dividend yield + Growth rate(Capital gain yield)
Cost of equity = 8.00% + 36.00%
Cost of equity = 44.00%
