You have diminishing marginal utility if your willingness to pay for salt decreases as you increase your salt consumption. The marginal rate of substitution is the same thing except that you replace “money” by an other good, say sugar. So your marginal rate of substitution of salt for sugar is t Marginal Rate of Substitution (MRS): Definition and Explanation: The concept of marginal rate substitution (MRS) was introduced by Dr. J.R. Hicks and Prof. R.G.D. Allen to take the place of the concept of d iminishing marginal utility.Allen and Hicks are of the opinion that it is unnecessary to measure the utility of a commodity. If the marginal rate of substitution of X for Y or Y for X is diminishing, the indifference’ curve must be convex to the origin. If it is constant, the indifference curve will be a straight line sloping downwards to the right at a 45° angle to either axis. The marginal rate of substitution is the rate of exchange between some units of goods X and у which are equally preferred. The marginal rate of substitution of X for Y (MRS) xy is the amount of Y that will be given up for obtaining each additional unit of X. This rate is explained below in Table.2. The marginal rate of substitution at a point on the indifference curve is equal to the slope of the indifference curve at that point and can therefore be found out by ate tangent of the angle which the tangent line made with the X-axis. In Fig.
To decrease the marginal rate of substitution, the consumer must buy more of the good for which he/she wishes the marginal utility to fall for (due to the law of diminishing marginal utility). Using MRS to determine Convexity. When analyzing the utility function of consumer's in terms of determining if they are convex or not.
"The law of diminishing marginal utility is at the heart of the explanation of them proceed the decreasing marginal rates of substitution of indifference curves. Various laws of economics are derived on the basis of marginal utility. For example law of demand, law of substitution, concept of consumers' surplus, etc. In other words, the marginal utility of a commodity diminishes as the con- thus, on the axiom of diminishing marginal rate of substitution (see below). 4. The reason behind this shape involves diminishing marginal utility—the of the indifference curve changes because the marginal rate of substitution—that is,
