Suppose you must estimate the cost of equity for a firm, and you have the following data: rRF = 5.5%; rM – rRF = 6%; b = 0.8; D1 = $1.00; P0 = $25.00; g = 6%; and rd = the firm's bond yield = 6.5%. What is this firm's cost of equity using the bond-yield-+-risk-premium approach? Use a 4% judgmental risk premium in your calculation.
