(a) Derive her demand for cake (x), as a function of prices p., py and her budget I. (b) Looking at the demand function in (a), is cake a normal good or an inferior good? Are cake and ice cream complements or substitutes? (c) Calculate the (i) (own) price, (ii) income, (iii) cross-price elasticity of demand for cake at the point where I = 80, px=10, py=20..

8. Let be the utility function U(x, y) =(xi + 2ya), , where x and y are the quantities consumed of two goods. (a) Show that the functional equation U(x, y) U(2,2) defines y as a function of x in a %3D neighborhood of point (2, 2). (b) If the quantity consumed of good x increases by 1 unit, by how much does the quantity have to increase or decrease? Consumed of the good and to keep utility constant? (c) If the quantity consumed of good x increases by 1%, by how much does the quantity have to increase or decrease? Consumed of the good and to keep utility constant?
Needed answer for (d) (e) Question 1 Consider a consumer with the following quasi-linear utility function U = x? + 5y Assume that the consumer faces a price of $1 for good Y, and a total income of $120. The price of good X decreases from $4 to $2. a) Find the optimal basket at the initial price P, = $4. Label it basket A. b) Find the optimal basket at the final price of P, $2. Label it basket C. c) What is the total effect of the price change? d) Find the decomposition basket (label it B) that will allow us to decompose the total change in X into the substitution effect and the income effect. Recall that the decomposition basket must satisfy two conditions: (1) it must generate the same utility level as the initial bundle A (2) Its tangency occurs with the decomposition budget line that has the same slope as the new budget line. What is the change in X due to the substitution effect? due to the income effect? e) Based on the income effect that you found, is the good X an inferior or a…
2. Sally consumes two goods, X and Y. Her utility function is given by the expression U = 3XY². The current market price for X is £10, while the market price for Y is £5. Sally's current in come is £500. (a) Sketch a set of two indifference curves for Sally in her consumption of X and Y. (b) Write the expression for Sally's budget constraint. Graph the budget constraint and determine its slope. (c) Determine the X,Y combination which maximises Sally's utility, given her budget constraint. (d) Calculate the impact on Sally's optimum market basket of an increase in the price of X to $15. What will happen to her utility as a result of the price increase?
VI. Utility Maximization 3. Consider an individual with the following utility function, U(x, x2) = ax5x95. The current price %3D of x, is 2 and the current price of x, is 4. 1. What is this consumer's budget constraint? 2. Calculate the optimal consumption of x, and x, if the consumer has income m.
2. Donald derives utility from only two goods, carrots (X) and donuts (Y). His utility function is as follows: U(X, Y) = XY. Donald has an income (M) of S120 and the price of carrots (Px) and donuts (PY) are both $1. a) Find the marginal utility that Donald receives from carrots (MUx) and from donuts(MUY) )
4. Let u(z) be a utility function that represents the preferences of a household. We say that the function v(r) is a monotonic transformation of u if f(-) is a strictly increasing function and v(z) = f(u(z)). (a) Show that if v(z) is a monotonic transformation of u, it represents the same preforences. (b) Can you explain why taking a monotonic transformation of a utility function does not change the marginal rate of substitution? (c) What kind of preferences are reprosented by a utility function of the form u(a1, 12) = VEi +#2? What about the function v(z1, r2) = 13z + 13r2? (d) Consider the function u(r1, 2) = VE1#2. What kind of preferences does it represent? Is the function (11, r2) jz a monotonic transformation of 1 u(r1, 12)? Is the function w(r1, 12) u(r1, 12)? = zfr a monotonic transformation of

b. A consumer purchases two goods, the amounts of which are x and y. Her marginal utility of consuming good x is Ux , while that of consuming good ? is Uy. If the two marginal utility functions are given by Ux = y2 + 2xy and Uy = 4xy + 3x2 − 3 and the consumer is known to stay on the same utility curve, find the total utility function of this consumer buying the two goods
