- 5. Consider a consumer whose utility function isu(x,y) = sqrt(xy) (MRS(x,y)=y/x)a. Assume the consumer has income $120 and initially faces the prices px = $1 and py = $1. Howmuch x and y would they buy? Draw the budget constraint and the demands. b. Next, suppose the price of x were to increase to $2. How much would they buy now? Draw thisin the same figure.c. Decompose the total effect of the price change on demand for x into the substitution effect and theincome effect. That is, determine precisely how much of the change is due to each of thecomponent effects. (Hint: See the lecture notes for the two properties that determine the locationof “z”, the reference point for distinguishing the income and substitution effects.)9) Jonathan spends his income (M) on good X and Y. His preferences are represented by theutility function(X, Y) = Ln X + LnY.The price of good Y is 1 and the price of good X is PX.(a) Derive his demand for X and Y. (b) Jonathan’s father considers X and Y as merit goods and wants to encourage his son toconsume more of them by offering him a subsidy of $1 for every unit of X that hepurchases. Suppose the initial price of X is $2, derive the substitution effect ofJonathan’s demand for X with the subsidy when his income is $20.(c) Does the subsidy increase Jonathan’s consumption of Y?(d) How does the subsidy affect Jonathan’s total spending on X and Y.(e) Instead of offering the subsidy, the father decides to spend the same amount of moneyon Jonathan by offering him an income supplement. Is this a better alternative thanthe unit subsidy in achieving the father’s objective? 12(a) Consider a perfectly competitive industry with several identical firms.The cost function of a price-taking firm…Columns 1 through 4 in the following table show the marginal utility, measured in utils, that Ricardo would get by purchasing various amounts of products A, B, C, and D.

- 6. My utility over goods 1 and 2 is given by: u(x1,x2)=min{x1/a,x2/b} Where x1is the quantity of good 1 I consume and x2 is the quantity of good 2 I consume. Assuming I purchase only goods 1 and 2... If a = 2, b = 5, the price of good 1 is $2/unit, the price of good 2 if $7/unit and my income is $5, how much good 2 will I consume to maximize my utility? (Note: The answer may not be a whole number, so round your answer to the nearest hundredth) (Note: The numbers may change between questions, so read carefully)Answer the following short questions:a. Suppose that a consumer’s preferences between goods x andy are represented by the utility function u(x, y) = x^2 + 16xy + 64y^2. If these two goods have the same price, describe the optimal consumptionchoice of this consumer.b. Suppose that when the price of a good change, the incomeand substitution effects change the consumer’s demand for that goodin opposite directions.i. Is this good a normal or an inferior good? Explain.ii. Is this good a Giffen or an ordinary good? Explain.c. Is the following statement true or false? The differencebetween a monopolist’s marginal cost and its profit-maximizing price issmaller when the demand is more elastic.Suppose that MUx = 20 and MUy = 10.

- Columns 1 through 4 of the accompanying table show the marginal utility, measured in utils, that Ricardo would get by purchasing various amounts of products A, B, C, and D. Column 5 shows the marginal utility Ricardo gets from saving. Assume that the prices of A, B, C, and D are $18, $6, $4, and $24, respectively, and that Ricardo has an income of $105. What quantities of A, B, C, and D will Ricardo purchase in maximizing his utility? How many dollars will Ricardo choose to save? Check your answers by substituting them into the algebraic statement of the utility‑maximizing rule. In other words, show it works when using this rule.11. A consumer’s utility only depends on the consumption of goods A and B according to the following Cobb-Douglass utility function: U(A, B) = A1/4 B3/4. The price of goods A and B are $10 and $15, respectively. The consumer has a budget of $1120 that he can use to consume the two goods. Write down the budget constraint and plot it. Calculate the optimal bundle and maximized utility for the consumer. A new tax of $5 is imposed on the price of good B. Compute the new optimal bundle of good A and B for the same consumer. What is the utility loss due to the tax? Show that the consumer would prefer a lump sum income tax that raises the same revenue as the tax on good B.1. Supposed that UMA Condominiums are an ordinary good and demand for Condominiums is inelastic. What is the effect on Nagenyos Consumer Surplus if there is a decrease in price of Condominiums? Explain. 2. Based from your answer in the questions pertaining to the supply of Condominiums in response to the demand of Nagenyos, enumerate at least two (2) possible effects of the determinants of demand ( (a) price, (b) income, (c) price of related goods like apartments and residential houses, and (d) consumer taste and expectation) and determinants of supply ( (a) flexibility of inputs, (b) mobility of inputs, (c) ability to produce substitute and (d) time ).
