In the conventional theory of firm, the major objective of a firm is to maximize profits. Maximization of profit simply refers to the maximization of rupee income of the firm. Under the profit maximization objective, the financial manager takes only those actions that are expected to contribute to the firm's overall profits. Corporations commonly measure profits in terms of earning per share, which represent the amount earned during the accounting period on each outstanding share of common stock.
The conventional theory of the firm depends profit maximization assumptions on the following grounds:
- only those firms survive in the long run in a competitive market which are able to make a reasonable amount of profit.
-Profit maximization assumption is a time-honored objective of a firm, and evidence against this objective is not conclusive.
-Profit maximization objective has been found extremely accurate in predicting certain aspect of firm's behaviour and trends.
- Though not perfect, profit, profit is the most efficient and reliable measure of the efficiency of a firm. It is also the source of internal finance.
-Under the condition of competitive market, profit can be used as a performance evaluation criterion, and profit maximization leads to efficient allocation of resources.
Although profit maximization has been the costly widely known objective of a business firm, some theorists have raised doubt on the validity of this objective. They have criticized the profit maximization objective on the following grounds:
-The profit maximization objective ignores the timing of returns. It equates a rupee received today with a rupee received one year later.
-Profit maximization goal dies not consider the cash flows available to stockholders. Owners receive cash flow either in the form of cash dividends paid to them or the proceeds from selling their shares for a higher price than initially paid. A greater EPS does not necessarily mean that a firm's board of directors will decide to increase dividend payments.
-Profit maximization goal ignores the element of risk associated with the expected earning streams.
- The profit maximization objective of the firm has greater relevance to short run. In long run, a firm can not service with this objective.
-A firm with this objective may involve in unfair practices to maximize profit.
-The term "profit" is vague. Profit may mean different things to different people. It is not clear whether it is before tax or after tax profit, short run or long run profit and total corporate profit or earning per share.
