c. JLB=I;XB=46 d. Xs=I;Ya=47 In a two-good world, a utility maximizer with strictly convex preferences has a perfectly inelastic demand curve for good X. Derive this demand curve in a simple indifference curve ldernand curve diagram (one right under the other) with a standard linear budget constraint. What kind of good must X be? Why? i. X is a(n) good in this case, and the substitution effect of a change in the price of X the income effect of that price change. Normal ; outweighs Inferior ; outweighs Neuter ; equals Inferior ; equals 9-.\" .0"? ii. If the demand for X is indeed perfectly inelastic, any decrease in the price of X will Not change the consumer's total expenditure on good X. Increase the consumer's total expenditure on good Y. Both (a) and (b) are true. Neither (a) nor (b) is true. 9.0 .0.\" Larry consumes only two goods, watches (X) and coffee (Y). He is a utility maximizer with strictly convex preferences and faces a linear budget constraint in prices and income [ Px'X + Pv'Y = I ]. Furthermore, we have observed that Larry's income elasticity of coffee demand is negative [ 6 1n Y / a [n]
