In a previous paper we reviewed the literature on normative stock price models. These models specified the present value of a share of common stock to be equal to the discounted value of dividends accruing to the holder. Using continuous discounting, the present value of a share is(1) where Dt is the dividend rate at time t and k is the cost of equity capital. Presumably k is a function of both the stockholders' time value of money and the perceived risk or uncertainty associated with the future dividend stream.
