What is the formula for marginal rate of substitution?
Marginal Rate of Substitution Formula The Marginal Rate of Substitution of Good X for Good Y (MRSxy) = ∆Y/ ∆X (which is just the slope of the indifference curve).
What does MUx MUy mean?
consumer by the marginal utility of X, MUx. Similarly, an additional unit of Y. increases the level of satisfaction of a consumer by the marginal utility of Y, MUy. The marginal rate of substitution is equal to the ratio of the marginal.
How do you calculate MUx and MUy?
To find the consumption bundle that maximizes utility you need to first realize that this consumption bundle is one where the slope of the indifference curve (MUx/MUy) is equal to the slope of the budget line (Px/Py) in absolute value terms. You know MUx = Y and MUy = X, so MUx/MUy = Y/X.
What is the marginal rate of substitution between two perfect substitutes?
When two goods are perfect substitutes, the marginal rate of substitution : – is constant along the indifference curve. – increases as the scarcity of one good increases. – changes to reflect the consumer’s changing preferences for the goods.
What will happen if Mrsxy PX PY?
if MRS > Px/Py, the consumer will consume more x and less y. If MRS < Px/Py, the consumer will consume less x and more y. If MRS = Px/Py, the consumer will not change their consumption. As Point A, MRS is greater than Px/Py, so José should consume more x and less y to maximize his utility.
What does the equation MUx PX MUy PY represent?
MUx/Px = MUy/Py, where MUx is the marginal utility derived from good x, Px is the price of good x, MUy is the marginal utility of good y and Py is the price of good y. A consumer should spend his limited money income on the goods which give him the most marginal utility per dollar.
What is Mrsxy at point C on U1?
Between point B and point C on U1, MRSXY = 3/2 = 1.5 (the absolute slope of chord BC). Between points C and F, MRSXY = 2/3 = 0.67.
What happens when MUx PX is less than MUy PY?
If MUx / Px is greater than MUy / Py, then the consumer will substitute good ‘x’ for good ‘y’. As a result the marginal utility of good ‘x’ will fall. The consumer will spend his money income in such a way that marginal utility of each good is proportional to its rupee.

What is the cross price elasticity of perfect substitutes?
Cross price elasticity of demand
| If the sign of X E D XED XED is… | and the elasticity is | the goods are |
|---|---|---|
| 0 | 0 | unrelated goods (neither complements nor substitutes) |
| positive | inelastic | somewhat substitutable |
| positive | elastic | very substitutable |
| positive | perfectly elastic (∞) | perfect substitutes |
How do you calculate MRS for perfect substitutes?
Here a and b are positive numbers, the MRSx.y = a/b = constant, the slope of an IC would be – a/b = constant. Since MRSx.y = a/b, the value of 1 marginal unit of good X to the consumer is equal to a/b unit of good Y, or, the value of ‘b’ unit of good X, on the margin, is equal to ‘a’ unit of good y.
