Verify that it is homogeneous of degree 1 in p and increasing in u. (b) Using expenditure function and Hicksian demand, calculate Walrasian demand and indirect utilityFor a > 0, consider a consumer whose utility function amounts to u(x1, x2) = − exp(−ax1x2). Can you take first order conditions to solve the utility maximization problem? Explain your argument. Next solve the utility maximization problem, and derive Marshallian demands and the indirect utility function. Given your calculations, state and use the duality theorem to find the expenditure function and Hicksian demand Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.1. Think about a utility function U(x,y) =xy, the budget constraint is px*x +py*y= m. A. Please derive the expenditure function. If originally m = 8, px=1, py=4. Now px has increased to 2. B. Based on (A), after the price change, how much should be compensated to maintain his original utility level? C. Use the Shaphard's Lemma to derive the Hicksian demand functions.

Suppose MRSx,y = MUx/MUy = 0.1(a) If the consumer substitutes 10 units of X for one unit of Y, then the utility remainsunchanged(b) Regardless of prices, the consumer will only consume Y(c) If the consumer substitutes 1 unit of Y for 0.1 unit of X, then the utility remainsunchanged(d) Regardless of prices, the consumer will only consume XUtility functions of a consumer: U = 20x10.4x20.4 Specify:a. marginal utility of each item.b. If the consumption of x1seee is 80 and x2 as much as 60 units, the price of Px120 and Px2 25, Determine if there is a balance of consumption?Assume, as in Exercise 22.1, that a consumer has utility function F or fruit and chocolate. Determine the consumer's demand functions q1(P1, P2, M) and q2(P1, P2, M). Determine also It* in terms of P1, P2 and M. Find the indirect utility function and show that It* = 8Vj8M. Suppose, as before, that fruit costs $1 per unit and chocolate $2 per unit. If the income is raised from $36 to $36.5, determine the precise value of the resulting change in the indirect utility function. Show that this is approximately equal to (O.5)λ*, where λ* is evaluated at P1 = 1,P2 = 2 and M = 36. Exercise 22.1 A consumer purchases quantities of two commodities, fruit and chocolate, each month. The consumer's utility function is For a bundle (X1, X2) of X1 units of fruit and X2 units of chocolate. The consumer has a total of $49 to spend on fruit and chocolate each month. Fruit cost $1 per unit and chocolate costs $2 per unit. How many units of each should the consumer buy…
- Intermediate Econmics Suppose an agent has a utility function u (x, y) = x2y2(a) Set up the expenditure minimization problem and solve for the Hicksian demand functions asfunctions of prices and utility.(b) Find the expenditure function as a function of prices and utility.u(x,y)=x·y2(MUx =y2,MUy =2x·y) Prove that the consumer is indifferent between the consumption bundles (1,4) or (4,2). What is the formula for the consumer’s MRS? What is the slope of the consumer’s indifference curve at the bundle (2,4)? State the two conditions that determine an interior solution to the consumer’s utility maximization problem. Assuming the consumer has income I = $90 and faces prices px = $1 and py = $2, show that each of the following consumption bundles satisfies one of the conditions in part d but not the other, and hence is NOT a solution to the consumer’s problem: i. (60,15) ii. (20,20) iii. (40,40)Joanna is playing blackjack for real money. She has reference-dependent preferences overmoney: if her earnings are m and her reference point is r, then her utility is v(m − r), wherethe value function v satisfies v(x) = √x for x ≥ 0, and v(x) = −2√−x for x ≤ 0a) Graph Joanna’s utility function as a function of m − rb) Does Joanna’s utility function satisfy loss aversion? Does it satisfy diminishingsensitivity?Suppose that Joanna has linear probability weights (that is, she does NOT have prospecttheory’s non-linear probability weighting function). Hence, if she has a fifty-fifty chance ofgetting amounts m and m′, and her reference point is r, her expected utility is1/2v(m − r) + 1/2v(m′− r) (2)For parts (c), (d), and (e), assume that Joanna’s reference point is $0 (that is, no winsor losses) and answer the following questions for each part: (i) What is the g for whichJoanna would be indifferent between not gambling and taking fifty-fifty win $g or lose$4 gamble?
