Money comparison

As stated previously, the source of capital is often not known, and hence it is not known whether or not Eq. (A. 10) is appropiiate to represent the cost of capital. Equation (A. 10) is, strictly speaking, only appropriate if the money for capital expenditure is to be borrowed over a fixed period at a fixed rate of interest. Moreover, if Eq. (A. 10) is accepted, then the number of years over which the capital is to be annualized is unknown, as is the rate of interest. However, the most important thing is that even if the source of capital is not known, etc., and uncertain assumptions are necessary, Eq. (A. 10) provides a common basis for the comparison of competing projects. 

Measurement of specific chemical or biological contaminants can be very expensive. Before expending time and money to obtain measurements of indoor air pollutants, you must decide how the results will be used (e.g., comparison to standards or guidelines, comparison to levels in complaint-free areas) what substances(s) should be measured where to take, samples when to take samples what sampling and analysis method to use so that the results provide useful information. 

At a time of rising expenditure and budget constraints, all health-care systems require evidence about the value for money of the care provided. This includes comparisons of the... 

In general, one or more of three methods are used to justify major expenditures. The first, payback, is a measure of the time it will take for cumulative benefits to equal cumulative costs (time to break even). This, by itself, may not be sufficient to compare alternative investments and projects competing for the same limited resources so one of two other methods may be used. These methods, Net Present Value and Internal Rate of Return, consider the earning power of money in making comparisons. Because investments earn compound interest, a dollar to be gained in the future has less present value than one gained today. The NPV is computed by estimating the yearly... 

In comparison to Marx, therefore, the circuit approach significantly reduces the amount of money that has to be advanced in order for the production process to be initiated. 

The concept of fistulated animals may seem abhorrent. It should be observed, however, that properly tended animals appear to be quite contented, and that their lifetime as an experimental animal is far longer than it would otherwise have been. Nevertheless, it is impossible to prevent the animal from knocking the cannula, and it is easy for leaks to occur causing irritation to the skin around it. It is also expensive to maintain such animals in an acceptable way, and to justify this if long periods exist between experiments. The procedure is favoured by experienced researchers as it facilitates comparison of results with earlier published work, and may give more consistent results over periods of time. However, improved within-batch precision, economy of time, money and convenience, and improved public... 

Solution The UAC method will be used as a basis for comparison. It is assumed that all money flows are continuous, and continuous interest will be used. 

Here are some words that tell you to use the operation of subtraction less, lower, fewer, difference, minus, and, of course, subtract. Someone can weigh 10 pounds less than another person (fie on them). Your colleague can make a lower salary than you (but you deserve it). To make comparisons of things such as weights or money or temperatures, you subtract. 

The point of this discussion is to note that it does not appear to be feasible or, indeed, desirable to base a comparison of the cost of drug therapies as a whole on the simple cost of the drug per dose or per annum alone. A biotechnologically derived drug may cost a great deal of money per unit dose, but the actual cost/benefit ratio may be such that society can absorb the cost. This topic does not appear to have... 

In financial matters, a similar technique, ratio analysis, is used to judge whether a company is healthy witli respect to industry standards. In ratio analysis most of die quantities compared are quantities of money, so the ratio of one quantity of money to another quantity of money is, by definition, a new dimensionless ratio (like die Reynolds number or lift coefficient), and these financial ratios can be used to compare businesses in similar industries or businesses (in engineering, such comparison is referred to as dynamic similitude). 

Mary L. Mandich, Lucent Technologies I have a question directed toward Michael, about the comparison of innovation and research with stocks. Maybe I am overly influenced by a book called Stocks for the Long Run, by Jeremy J. Siegel and Peter L. Bernstein, but the basic point of that book was that you would make the most money in the long run not if you tried to find one stock that would do superbly well, but if you backed really good horses. There is a dichotomy of market-driven research that will make a lot of money versus the fundamental belief that innovation is the way to go. I see a conflict there, and maybe you can resolve it better than I can. 

FOLLOWING THE feasibility study, the next stage in the design project is the evaluation and comparison of the alternative process routes for manufacture of the chemical. The selection of an appropriate process is an important decision, all the subsequent work depends upon this choice. Although the selection can be changed or modified at a later stage, at least before the plant is built, such a decision results in a serious waste of time and money. However, probably not such a waste as building an uneconomic or unsafe plant ... 

Return on original investment. This method is also known as the engineer s method, the du Pont method, or the capitalized earning rate. It does not take into account the time value of money because of this, it offers a more realistic comparison of returns during the latter years of the investment. The return on original investment is defined as follows ...

It is, of course, possible to add up all of the revenues over the project s lifetime and to compare this sum with the total investments. If the revenues exceed the costs, then the project is apparently profitable, but if the reverse is true, it is not profitable and no manipulative techniques will be able to make it so. The comparison of costs and revenues, in an appropriate fashion, is the target of economic appraisal, and its first problem is to deal with the time value of money. 

There are two simple factors that can be used for comparison, either with established targets or among several competing projects, which make no allowance for the ways in which money is spent or received, and hence do not allow for the time value of money ... 

In fact, the best balance point is the date on which operation starts, because at that time, all expenditures should be complete, and no revenues have yet started to accrue. All sums of money, input or output, are then discounted, forwards or backwards, to this comparison point in time. 

The discounting process enables the conversion of any sum of money involved in the project to its present value (PV) at the point of comparison. (Confusingly, present does not necessarily mean now ,... 

This simplified example has been used to illustrate the basic concepts involved in making comparisons of alternative investments. The approach was based on using the simple return on initial investment in which time value of money is neglected. Although this method may be satisfactory for preliminary and rough estimations, for final evaluations a more sophisticated approach is needed in which the time value of money is considered along with other practical factors to assure the best possible chance for future success. Typical more advanced approaches of this type are presented in the following sections. 

Example 5 Comparison of alternative investments by different profitability methods. A company has three alternative investments which are being considered. Because all three investments are for the same type of unit and yield the same service, only one of the investments can be accepted. The risk factors are the same for all three cases. Company policies, based on the current economic situation, dictate that a minimum annual return on the original investment of 15 percent after taxes must be predicted for any unnecessary investment with interest on investment not included as a cost. (This may be assumed to mean that other equally sound investments yielding a 15 percent return after taxes are available.) Company policies also dictate that, where applicable, straight-line depreciation is used and, for time-value of money interpretations, end-of-year cost and profit analysis is used. Land value and prestartup costs can be ignored. 

Upon my return, the Princeton chemistry department seemed very different from the image I had retained antiquated, no comparison with Harvard. Eventually I rose to a chaired professorship, but, after 21 years, I left for Erlangen, Germany, in 1976. Most were amazed by my decision. My motivation was twofold. One was cultural the tradition, the beauty, the art, the history, the quality of life, and the diversity of Europe, where I had been invited as visiting professor many times, drew me. But the main reason was scientific the availability of computer time. My interest in what today is called computational chemistry had been increasing since the late 1960s. It was simply not possible to pursue a computer-time-intensive field in Princeton in 1976. An hour of CPU time at the Computer Center cost 800 of grant money, and the speed of the machine was about that of an early PC. To induce me to stay in Princeton, I was offered two hours of free computer time a week (for two years) ...
