Discounting

Principle of DIscounting

 A fundamental principle of economics which is used by almost all the persons In their dally Ilfe is that the worth of a rupee of tomorrow is lesser than that of a rupee of today. This principle is based on a well-known proverb, "A bird in hand is better than two in the bush" It means that a difference should be made between cash received at different times. Money recelved today could be invested to earn additional money immediately. On the other hand, an amount to be recelved after certain period of time could not be invested until it is received, therefore, It is less valuable than a rupee received today. Therefore, the time of receipt of amount should be duly taken into consideration in the solution of a particular problem. ) 

Example : 

Suppose you get an offer to make a choice between a gift of 1,000 today or 1,050 next year. Naturally, you will prefer to get 1,000 today for two reasons: (1) Future is always uncertain. So, there may be uncertainty in getting 1,050)lif the present opportunity is not availed of (i) The amount of ? 1,000 received today will carn interest for one year and thus, it will be more than 1,050. Therefore, the principle of discounting is véry important, particularly in investment decisions. 

Principle of Equimarginal : This principle is also known as the principle of maximum satisfaction. It is the most popular principle of economics. According to this principle, an input should be allocated in such a manner that the value added by the last unit of input is same in all uses. Thus, this principle provides a base for maximum exploitation of all the productive resources of a firm so that the profitability of the firm may be maximised. 

Example : Assume that there are 200 workers working in a firm and the firm is producing four types of product, i.e. Product A, Product B, Product C and Product D. All the products require the services of labour. The firm has allocated these workers on the production of these products on a certain basis. Firm can increase the production of any of these products, but to do so, the production of any other commodity will have to be reduced. If the firm decides to increase the production of product A, the production of either product B or product C or product D will have to be reduced. Labour should be shifted from low marginal value activity to the high marginal value activity so that the total value of all the products may be maximum
