If at the current consumption bundle where all income is spent, the slope of the indifference curve at this bundle is steeper than the slope of the budget line, and X is on the horizontal axis
a. the consumer is willing to give up more of good Y to get an additional unit of good X than is necessary under the current market prices.
b. MRS < PX /PY.
c. MRS = - PX /PY.
d. the consumer is willing to give up more of good X to get an additional unit of good Y than is necessary under the current market prices.
The answer is a.
a. the consumer is willing to give up more of good Y to get an additional unit of good X than is necessary under the current market prices.
The MRS is the slope of the indifference curve and Px/Py is the slope of the budget constraint.This means that the marginal rate of substitution is higher than the ratio of the price of x to the price of y.The marginal utility per dollar spent on good X is greater than the marginal utility per dollar spent on good Y.
