Gladys (who is careful with her money) is going to give her daughter, Beatrice, money for her birthday, and wants to minimise the amount she gives subject to Beatrice being able to attain a specified, fixed level of utility, uo. Beatrice’s utility function (which is known to Gladys) has indifference curves with the usual properties and she consumes two goods, x and y with pricespx, py respectively; Beatrice’s income consists entirely of Gladys’ cash gift to her, all of which she will spend on x and y.

(a) Use a diagram to illustrate Beatrice’s optimal choice. Explain carefully the nature of at Gladys’ choice problem in terms of this diagram? (5 marks)

(b) What will happen to the amount of x Beatrice consumes, and the amount of money Gladys will give her, if px rises? Answer by careful reference to a diagram only. Explain, briefly why you can be sure of the directions of these two effects of the rise in px by reference only to the diagram. (5 marks)

    Utility Maximization with Substitutes Carol needs to decide how to spend her wealth on fish and chicken. For Carol, 1 lb of fish is equivalent to 2 lb of chicken. Her preferences can be represented by the utility function u(x, y) = 2x +y where x is the quantity of fish (in lbs) and y is the quantity of chicken (in lbs). The consumption set is R 2 +. (a) Draw two typical indifference curves for Carol, one corresponding to...

    Suppose that there two goods, X and Y , available in arbitrary nonnegative quantities (so the the consumption set is R 2 +). The consumer has preferences over consumption bundles that are monotone, strictly convex, and represented by the following (differentiable) utility function: u(x, y) = α √ x + (1 − α) √ y, where x is the quantity of good X, y is the quantity of good Y , and α ≥ 0 is a utility parameter. The...

    Question 9 1 pts Logan Roy is spending all his money income by buying mineral water and popcorn. At his current consumption level, the marginal utility of mineral water is 70 and the marginal utility of popcorn is 60. The price of a bottle of mineral water is $2.00 and the price of a box of popcorn is $1.50. The utility-maximizing rule suggests that Logan should: O Increase consumption of popcorn and increase consumption of mineral water Decrease consumption of...
