Charlie's utility function is xAxB. The price of apples used to be $1 per unit and the price of bananas was $2 per unit. His income was $40 per day. If the price of apples increased to $2.25 and the price of bananas fell to $1.25, a. compute the optimal consumption bundle for both goods before the price change; b. Compute the daily income after the price change in order to be able to just afford his old bundle.
Charlie's utility function for his consumption of apples xA and bananas xB is u(xA, xB) = xAxB. If the price of apples is pA = 3 and the price of bananas is pB = 1, and Charlie has $12 to spend on apples and/or bananas, then: The budget equation is 3 x A + x B = 12 And the optimization condition (to maximize Charlie's utility) is − x B x A = 3 Given these two conditions, find Charlie's...
Charlie consumes apples and bananas. His utility function is: U(xA; xB) xAxB. The price of apples is $1, the price of bananas is $2, and Charlie's income is $40 a day. The price of bananas suddenly falls to $1. Find the substitution and income effect of the price change for apples and bananas.
4. Charlie likes both apples and bananas. He consumes nothing else. Charlie consumes x bushels of apples per year and x bushels of bananas per year. Suppose that Charlie's preference is represented in the following utility function: u(x,,Xy)-x,Xy . Suppose that the price of apples is S1, the price of bananas is S2, and Charlie's income is $40. (14 points) a. Draw Charlie's budget line. Plot a few points on the indifference curve that gives Charlie a utility of 150...
1. Charlie’s utility function for weekly consumption of bananas (B) and Apples (A) is given by U = BA . a. Suppose Charlie consumes 20 bananas and 10 apples in a week. Sketch his indifference curve through that bundle on a diagram. (While it doesn’t really matter which good is on the horizontal axis, for consistency with our classwork, assume bananas are on the horizontal axis.) b. Use calculus (partial derivatives) to derive formulas for the marginal utilities (MU) of...
1. Charlotte loves apples and hates bananas. Her utility function is U (a,b) a-b2/4, where a is the number of apples she consumes and b is the num- ber of bananas she consumes. Assume that Charlotte's income is y • What are the demand functions for Charlotte ? • What are the Engel curves for Charlotte? 2. Wilbur likes both apples and bananas. His utility function is U(a,b) = ab1/2. Assume Wilbur's budget is m, the price of apple is...
