2. Answer true, false, or it depends. Explain your answer using indifference curve analysis for a, b, and e, and using the formula for price elasticity of demand for (c) and (d).

a- Suppose that X and Y are perfect substitutes, MRSxy = 3, Px = $4, Py = $2, and I = $10. Then, the consumer will spend all her income on good Y, purchasing 5 units.

b- For an inferior good, the substitution and income effects work in the same direction if the price increases but in opposite directions if the price decreases.

c- For two parallel demand curves, the one further to the right has a smaller price elasticity at each price.

d- When two demand curves intersect, the flatter of the two is more elastic at the point of intersection.

e- In a world with only 2 goods, X and Y, it is not possible for both goods to be inferior.

A consumer has typically shaped indifference curves and budget constraint and is currently spending all her income. She is consuming a bundle of goods such that her MRSXY is greater than PX /PY . This consumer could increase her utility by: a. consuming more of good X and less of good Y b. consuming more of good Y and less of good X c. neither of the above because we can tell she is already maximizing utility because she is...

Dan’s preferences are such that left shoes (good x) and right shoes (good y) are perfect complements. Specifically, his preferences are represented by the utility function U (x, y) = minimum{x, y}. (a) Draw several of Dan’s indifference curves. Which bundles are at the “kink- points” of these curves? (b) Assume that Dan’s budget for shoes is M = 10 and that the price of a right shoe is py = 2. Find and draw Dan’s demand curve for left...
