Among the various types and classes of business problems, the most complex and troublesome for the business manager are those relating to the firm’s capital investments. Capital management implies planning and control and capital expenditure. In this procedure, relatively large sums are involved and the problems are so complex that their disposal not only requires considerable time and labour but also top-level decisions. The main elements dealt with cost management are:
- Cost of capital
- Rate of return and selection of projects.
The various aspects outlined above represent the major uncertainties, which a business firm has to consider viz., demand uncertainty, cost uncertainty, price uncertainty, profit uncertainty and capital uncertainty. We can, therefore, conclude that managerial economics is mainly concerned with applying economic principles and concepts to adjust with the various uncertainties faced by a business firm.
