(a) if the market believes the 60% payout ratio will continue for ever, and if everyone uses the constant growth dividend discount model to value the compant stock, what rate of return are investors apparently requiring?(hint: start by calculating the earnings growth rate)
(b) suppose you think the company will pay out 60% for the first two dividends, then increase the payout ratio to 80% from the third dividend onwards. if you required rate of return is 16.7% per annum, how much would you be willing to pay for the company stock?
