The diminishing marginal rate of substitution (MRS) refers to the rate at which a consumer is willing to give up one good in order to obtain more of another good, while still maintaining the same level of utility or satisfaction. In other words, it measures the slope of the indifference curve, which represents the set of combinations of two goods that provide the same level of utility to the consumer.

The MRS decreases as the consumer consumes more of one good and less of the other. This phenomenon is known as the law of diminishing marginal utility, which states that as a person consumes more of a particular good, the additional utility or satisfaction they derive from each additional unit of that good decreases. For example, if a consumer is choosing between two goods, X and Y, they may initially be willing to give up two units of Y in order to obtain one additional unit of X. However, as they continue to consume more of X and less of Y, the MRS may decrease to the point where they are only willing to give up one unit of Y for one unit of X.

The MRS is an important concept in economics because it helps to explain consumer behavior and how consumers make trade-offs between different goods. It is also a key factor in the analysis of consumer demand and the determination of market equilibrium.

In conclusion, the diminishing marginal rate of substitution is the rate at which a consumer is willing to give up one good in order to obtain more of another good, while still maintaining the same level of utility. It is a crucial concept in economics that helps to understand consumer behavior and the determination of market equilibrium.

## Law of Diminishing Marginal Rate of Substitution In this model, the points on the indifference curve represent the number of units of each good that would be substituted for one another. Thus, it recognizes the interdependency of commodities on each other. That the marginal rate of substitution of X for Y diminishes can also be known from drawing tangents at different points on an indifference curve. Coca-Cola and Pepsi are considered to be perfect substitutes for each other. Straight Line Indifference Curve: If MRS of X for Y or Y for X is diminishing, the indifference curve must be convex to the origin. To find the marginal rate of substitution, you can multiply the price of a hamburger by the price of a hot dog.

## Marginal Rate of Substitution (MRS) For example, when a consumer sacrifices 3 units of wheat for one unit of rice, the marginal rate of substitution becomes 3:1. Owing to higher marginal significance of good X and lower marginal significance of good Y in the beginning the consumer will be willing to give up a larger amount of Y for a unit increase in good X. This utility function can then be divided by the marginal price of the good. Thus, the marginal rate of substitution of rice for wheat goes on diminishing. This would lead to the consumption of X over Y. At that point, your MRS drops to 2, meaning you are willing to give two units of clothing to consume an additional unit of food.

## MRS in Economics: What It Is and the Formula for Calculating It If the price of a good increases, it may be better to sacrifice that product for a cheaper one. It is linked to the indifference curve, from where consumer behavior is analyzed. The following table shows the four combinations for Mr. A decreasing indifference curve is indicative of a convex preference. Since shoes are perfect complementary, at point В of I curve an additional right shoe will not increase his satisfaction 90° until he gets another left shoe of the same size. However, the marginal rate of substitution does not remain constant and may need to be recalculated often.

## What is a diminishing marginal rate of substitution? Law of diminishing marginal utility means that as more units of a good are consumed, the marginal utility received from the consumption of every additional unit of the good declines. In this case, the indifference curve will be L-shaped, implying an increase in the consumption of both commodities. Who is the father of diminishing marginal utility? In other words, as the consumer has more and more of good X, he is prepared to forego less and less of good Y. Once the marginal rates of substitution are calculated, it can be used to estimate the price of a commodity. The amount of У he is prepared to give up to get additional units of X becomes smaller and smaller. Keynes expanded on the concept of liquidity preferences and built a general theory of how the economy worked.

## Marginal Rate of Substitution Marginal rate of substitution is the rate at which consumer will give up a quantity of goods for the exchange of another good. You could now spend your money on one of three activities. Likewise, an increase in unit consumption of rice results in the sacrifice of 1 unit of wheat. This is the case of perfect substitute goods like Lux and Godrej soap, Tata and Brooke Bond Tea, etc. What is the definition for diminishing marginal utility? If the slope remains constant, the indifference curve can be a straight line.

## The Law of Diminishing Marginal Rate of Substitution (DMRS) As a consumer consumes more of one commodity, he will also lose units of another. However, as a new product or service is introduced, the marginal rate of substitution will decrease. None of the above. The diminishing marginal rate of substitution is why the indifference curve is convex bowed inward. The marginal rate of transformation is different for each type of good, but it helps management calculate the value of an extra unit of a product.

## Opportunity Cost and the Indifference Curve In other words, the marginal rate of substitution of X for Y falls as the consumer has more of X and less of Y. Opportunity cost The opportunity cost of marginal rate of substitution is the amount of one good that a consumer will give up to buy another. If the marginal rate of substitution of hamburgers for hot dogs is -2, then the individual would be willing to give up 2 hot dogs for every additional hamburger consumption. How is it used in economics? As a result, therefore, as the individual substi­tutes more and more of X for Y, he is prepared to give up less and less of Y for a unit increase in X. Another important difference between an indifference curve and a consumption curve is the income effect. If it is con­stant, the indifference curve will be a straight line sloping downwards to the right at a 45° angle to either axis, as in Fig. Comparison of Laws: — Law of Diminishing Marginal Utility and Law of Diminishing Marginal Rate of Substitution: According to Prof.

## Explain the meaning of diminishing marginal rate of substitution with the help of a numerical example. MRS does not necessarily examine marginal utility since it treats the utility of both comparable goods equally, though in actuality they may have varying utility. Marginal Rate of Substitution Definition Let's consider the marginal rate of substitution definition. It is also known as the law of diminishing marginal rates of substitution. For example, in the case of oranges and mangoes, a user will normally reduce the consumption of one fruit if he consumes more of another fruit. Most indifference curves are usually convex because as you consume more of one good you will consume less of the other. But what exactly is an MRS? Then the MRS at another point is 3, meaning 3 units of coffee are exchanged per additional unit of Pepsi.
