Correct answer
Indifference curve either intersect or are tangent to one another
Why this answer is correct
The correct answer is Indifference curve either intersects or are tangent to one another.
Key Points
- Indifference curve either intersect or are tangent to one another:
- This is incorrect. Indifference curves represent different levels of satisfaction or utility. If two indifference curves were to intersect, it would imply that the same bundle of goods provides two different levels of satisfaction, which is logically inconsistent. Therefore, indifference curves cannot intersect or be tangent to one another.
Additional Information
- Indifference curve slopes downwards to right:
- This is correct. Indifference curves slope downwards to the right because, to maintain the same level of satisfaction, an increase in the quantity of one good must be accompanied by a decrease in the quantity of another good.
- Indifference curve of imperfect substitutes are convex to the origin:
- This is correct. Indifference curves are convex to the origin because of the diminishing marginal rate of substitution. As a consumer substitutes one good for another, the amount of the good being given up decreases at a diminishing rate.
- Upper indifference curves indicate a higher level of satisfaction:
- This is correct. Higher indifference curves represent higher levels of satisfaction because they correspond to larger quantities of one or both goods.
