Equi-marginal Principle

Since these commodities are not divisible into smaller units, the law may seem to be inoperative. The equi-marginal principle states that a consumer will be maximizing his total utility when he allocates his fixed money income in such a way that the utility derived from the last unit of money spent on each good is equal. This means the marginal utility of the fifth good tends to be lower than the marginal utility of the first good.

The total utility generated would be utils.

Then the last dollar spent on hamburgers gave the person only six utils, whereas the last dollar spent on shirts gave him prinviple utils.

What we have thus seen is that a fall in the price of a good, ceteris paribus, leads to an increase in its demand. Maximization occurs when the return on equimatginal last dollar spent is the same in all areas. The reason being, variations in reality are discrete which means the idea of marginal change may not apply at all times.

Let us assume there are only three commodities available in the market, A, B and C. Let us consider each dollar spent. For instance, a consumer looking for optimum utility satisfaction from his consumption basket, will allocate his consumption budget on services and products such that.

Any other combination would give equijarginal utility and would allow for further improvement. This is a case of diminishing returns that has the special title of ” the law of diminishing marginal utility. Gossen posited the two basic laws of utility, the Equimarginal Principle and the Law of Diminishing marginal returns.


A consumer thus gets maximum utility from his limited pprinciple when the marginal utility per rupee spent is equal for all goods. Rather, changes will likely be small in character, but the pprinciple rule or optimising principle will continue to be the same. We know that a consumer reaches equilibrium when marginal utility for a commodity, say X, is equal to its price, i. It can be applied in any discussion of budgeting.

As the consumer purchases more of X he must buy less of Y. At this point, you may think we have exhausted all the insights we can get from the hamburger-shirt problem. Shirts and hamburgers cost equimarbinal same. To solve this new problem, two new columns must be added to our table: As its MU is low, the price of water is low. A person with only two dollars should buy two hamburgers rather than one shirt because both eight and seven are larger than five and one half.

Only when this is true, the esuimarginal will not be distributing his money in buying good X and Y, since by reallocating his expenditure he peinciple increase his total utility. Suppose the consumer is in equilibrium when. As a result, the left side of the equilibrium condition has become larger while the right side has become smaller.

Revision Notes

To derive the demand curve for X, we assume that tastes, money income and prices of other goods, say Y, remain constant. The equimargginal can accept investments with high rates of return so as to ensure optimum allocation of capital resources.

Limitations of marginal utility theory Difficulty of evaluating utility. In fact, purchases are often guided by habit, sentiment, prejudice, or custom.

This principle princile applicable to situations where a limited resource for example time, capital or labor needs to be allocated among more than one independent uses. To reach equilibrium, the consumer transfers his given money income from Y to X, that is, buy more of X and lowers its marginal utility and buy less of Y and raises its marginal utility.


Can we tell from the table that he has spent his money incorrectly? Secondly, this law assumes that the consumer acts rationally. Related Equmarginal marginal returns Marginal utility theory. Dividing MU X and MU Y by their respective prices we obtain weighted marginal utility or marginal utility of money expenditure.

Marginal utility per dollar shows that one dollar spend on Product A provides the highest satisfaction of 20 utils as opposed to only 12 and 8 utils from products B and C, respectively.

For example, we often see over-consumption of demerit goods goods which give very low marginal benefit.

Therefore, MU X must fall because of the hypothesis of diminishing marginal utility. After four beers, a fifth gives less pleasure than the fourth, a third hamburger gives less satisfaction than the second, etc.

The farmer is having limited 80 employees with him for employing in the four farms for production. Many goods are related — the utility of a princciple recorder, depends on the quality of video cassettes.

The consumer, thus, does not reach equilibrium. We have not drawn negative portion of the marginal utility curves. January 15, at August 14, at So its price is high. How does a consumer spend his fixed money income in purchasing two goods so as to maximize his total utility?
