Calculate the price of a firm with a plowback ratio of 0.60 if its ROE is 20%. Current earnings, E(1), will be $5 per share and k = 12.5%. What if ROE is 10%, which is less than the market capitalization rate? Compare the firms price in this instance to that of a firm with the same ROE and E(1) but a plowback ratio of b = 0.
