Larry's utility function is U = 4X + 12Y. Which property of consumer preferences does Larry's utility function violate? Explain your answer.
Homework Answers
Here the Larry's utility function is a perfect substitute utility function meaning that Larry either prefers good X or good Y depending upon the price ratio being less than or more than the marginal rate of substitution. Here in this case the marginal rate of substitution is a constant value , 4/12, which is 1/3. This therefore means that the indifference curve is downward sloping straight line. Indifference curve are convex to the origin ideally meaning that the law of diminishing marginal utility holds but here the consumer is willing to give up the same amount of one good to get a unit of another good implying that law of diminishing marginal utility fails.
