Sorry about all the scribbles. The calculations got messy. Let me know if anything is unclear :)
Ed's utility from vacations (V) and meals (M) is given by the function U(V,M) = V...
Consider two goods, good 1 and good 2. The consumer’s utility function is given by U(x1,x2)=V(x1)+x2. Derive the ordinary demand function of good 1. When the market price of good 1 is given P1=P1' , derive the consumer’s surplus. If the price is changed to P1=P1", prove that the change measured by consumer’s surplus is the same as the Compensating variation. Also prove that it is the same as Equivalent variation.
Anna's utility function is given by U (r.y) = (r + 3) (y + 2), where I and y are the two goods she consumes. The price of good r is p ,. The price of good y is Py. Her income is m. (a) Write her maximization problem and find her demand functions for the two goods. Is it always possible to have an interior solution? Justify your answer. (b) Are the two goods ordinary or giffen? Are the...
Income and substitution, Compensating Variation: Show your work in the steps below. Consider the utility function u(x,y)-x"y a. Derive an expression for the Marshallian Demand functions. b. Demonstrate that the income elasticity of demand for either good is unitary 1. Explain how this relates to the fact that individuals with Cobb-Douglas preferences will always spend constant fraction α of their income on good x. Derive the indirect utility function v(pxPod) by substituting the Marshallian demands into the utility function C....
3. Suppose that Bob’s preferences can be represented by the utility function u(x, y) = 32x^0.5 + y. The MUx = 16x^-0.5 and MUy = 1. (a) Determine Bob’s demand functions for x and y. (b)If the price of x is $8, and Bob’s income is $1000, how many x would Bob consume? How much income would be devoted to spending on y? (c) Suppose that the price of x doubles to $16. Calculate the income and substitution effects. (d)Is...
Suppose that a consumer has a utility function given by u(x1, x2) = 2x1 + x2. Initially the consumer faces prices (2, 2) and has income 24. i. Graph the budget constraint and indifference curves. Find the initial optimal bundle. ii. If the prices change to (6, 2), find the new optimal bundle. Show this in your graph in (i). iii. How much of the change in demand for x1 is due to the substitution effect? How much due to...
1. Suppose that a consumer has a utility function U(x1,x2) = x0.5x0.5 . Initial prices are P1=1 and P2 = 1, and income is m 100. Now, the price of good 1 increases to 2. (a) On the graph, please show initial choice (in black), new choice (in blue), compen- sating variation (in green) and equivalent variation (in red). (b) What is amount of the compensating variation? How to interpret it? (C) What is amount of the equivalent variation? How...
John earns $120 per week and likes to consume wine and cheese. His utility function is of the form ?(?, ?) = (? ^1/2)(? ^3/2) where x denotes the amount of cheese consumed and y the amount of wine. His marginal utilities are ??? = (? ^3/2) / (2? ^1/2) and ??? = (3? ^1/2)(? ^1/2) / 2 d. The price of a bottle of wine is $10 and the price of a piece of cheese is $3. What is...
Consumer's surplus: A consumer has the utility function U(x,y) =e^((ln(X)+Y)^1/3) where X is the good in concern and Y is the money that can be spent on all other goods. (So the price of Y is normalized to be 1). The income of this consumer is 100. (a) (10pts) Derive the demand function of x for this consumer. Make sure that at every price of x, the consumer always has enough income to buy the amount of x as indicated...
Consumer's Surplus A consumer has the utility function U(, y)v) where is the good in concern ail y is the money that can be spent on all other goods (so the price of y is normalized to be 1). The income of - this consumer is 100. Bi Pr X10 (In(x)y) (10%) Derive the demand function of z for this consumer. (10%) Calculate the price elasticity of the demand function in (b) Is it true that the absolute value of...
2) Chimichanga Fest Your utility function is given by U-X,X, where xi s your consumption of Chimichangas and x, is your consumption of all the other goods in the economy. Yes, you spend 60% of your budget on Chimichangas, which is totally reasonable after the Dumpling House tragedy. a) Solve the utility maximization problem, finding the uncompensated demand for x, & x, and the indirect utility function in terms of p,, p, and Y. b) Solve the expenditure minimization problem,...
