Explain whether each of the following statements is true or false.
The marginal rate of substitution (MRS) diminishes as an individual moves downward along the demand curve. Assume the statement refers to good X with price Upper P Subscript Upper X , where good X is measured on the horizontal axis of an indifference map and good Y is measured on the vertical axis.
Marginal rate of substitution is quantity of good which a consumer will need to have in order to leave another good. The MRS equals to Px/Py. This will decrease when the demand curve decreases.
