EQUI-MARGINAL UTILITY.

EQUI -MARGINAL UTILITY.

To maximize utility, consumer allocate their income among good so to equate the marginal utilities per rupee (MU/P), of the expenditure on the last unit of each good purchased.
This is also refer to as consumer equilibrium.
                                     =MUx
                                        Px

Spending should be allocated across goods so that the marginal utility on the last rupee spend is the same. A consumer has a given income which he spent on various goods he want.

The equi-marginal condition for the equilibrium of consumer can be stated:-

1. When a consumer equalize weighted marginal utility of all goods, when the marginal utility of each good weighted by its price is equal.

2. When a consumer equalizes the ratio of marginal utility of goods with the ratio corresponding prices for each pair of good consumed.

3. Measure the marginal utility of a rupee`s worth of each good consumed at a given price consumer is said to be equilibrium.

EXAMPLES:- 

suppose apple and orange are two commodities to be purchased. suppose further that we have $7 to spend . let us spend $3 on orange and $4 on apple. so the result is, the 3rd unit of orange is 6 and the 4th unit of apple is 2. as the marginal utility of oranges is higher, we should buy more oranges and less apples.
