A Review of: “UNCERTAINTY AND ITS EFFECT ON CAPITAL INVESTMENT ANALYSIS,” by Martin B. Solomon,Jr. Management Science,Volume 12, No. 8, April 1966

In this paper we extend Thompson's [17] work using time series models within the discounted cash flow framework to estimate the cost of equity capita] for a firm. In particular we do the following: First, we prove the existence and uniqueness of a solution for the cost of equity capital. Secondly, we verify that the cost of equity function is continuously differentiable and derive the formula for its reliability. Formulas for both the cost and its reliability are in terms of infinite sums or infinite dimension matrices. Thirdly, we derive estimators of the cost of equity capital and its reliability which are in terms of finite sums and easy to calculate. We show that these estimated converge to the cost of equity capital and its reliability. Finally, our procedure for estimation applies to a wide variety of time series models that may be used to forecast dividends.

Review of:“ MAINTAINABILITY AND MAINTENANCE MANAGEMNT” by Joseph D. Patton,Jr., Instrument Society of America,Research Triangle Park,N.C., 1980, xiii + 441 pages,list $35.00.

To affect the actual project selection process of a corporate research lab, the project selection process needs to be simple and transparent enough to ensure effective communication among project leaders, research implementers and technology strategists. In this way, the project selection process stimulates project creation. If net present value (NPV) is our project criterion, this requires simplified NPV formulas. In this paper, we develop such formulas in the context of a major application.
