1. A consumer has 16 dollars. The price of x₁ is p₁ dollars, and the price of x2 is p2 dollars. The consumer has a utility function, u(x1, x2) = x1x2. (a) Write down the demand function of x1, and calculate the con- sumption of x1 when p₁ = 4. (b) Suppose the price of x₁ decreases from p₁ = 4 to p₁ = 2, what is the change in the consumption of x₁? (c) Calculate the substitution effect. Hint: You need to calculate an interim income m' such that the purchasing power is constant after the price change, then calculate Ax₁ = x₁(m', p₁) - x1 (16, p₁) (see p141-142, Varian).

(Review Question) Sarah consumes both wine ) and cheese (y) and considers them perfect substitutes. She always gets twice as much utility from consuming wine as she does cheese. What equation would represent her utility function? U-(2xy) U=x+2y U=2x+y U=min(x,2y)
Questions 1. Will's utility from vacations (91) and meals (92) is given by the function U(V, M) = 91 x 92. Last year, the price of vacations was $200 and the price of meals was $50. This year, the price of meals rose to $75, while the price of vacations remained the same. Both years, Will had an income of $1500. (a) What is the compensating variation for the price change in meals? (b) What is the equivalent variation for the price change in meals?
1. A consumer has a utility function defined over two goods X and Y. Let the quantity of Good X be x ≥ 0 and the quantity of Good Y be y ≥ 0. The utility function is given below: u(x, y) = xy + 2y. Assume that the consumer has income m and that prices are px and py. (a) Explain whether the preferences underlying this utility function satisfy completeness and transitivity. = (b) Explain whether the preferences underlying this utility function satisfy monotonicity and convexity (c) Find the consumer's Marshallian demands for Good X and Good Y at prices px > 0 and py > 0. (d) Show that goods X and Y are normal goods and explain whether either good is a substitute for the other. (e) Assume that px = 10, Py = 5 and m = 100. Suppose that px increases to p how much of the change in demand for Good X is via the substitution effect and how much is via the income effect? Note: You may assume an interior solution (i.e. x > 0 and y > 0). = 15,

2. Ping receives a weekly allowance to purchase soda (x) and juice (y) at school. His preferences over these two goods can be represented by the utility function U(x,y) =0.5x+ 5lny where x represents the number of cans of soda and y represents the number of juice boxes. a) Given his preferences find his Marshallian demand functions for soda (x) and juice (y). b) Suppose that the price of a can of soda is $1.5 and that Ping has $30 to spend on soda and juice. Write Ping's demand curve for juice (y). Illustrate his demand curve. c) Suppose that the price of a box of juice is $1 (the price of soda and income remain $1.5 and $30, resp.). Use your demand functions to find his best bundle. In an indifference curve diagram illustrate his best bundle at these prices. For the remainder of the question assume that Ping's allowance (income) rises to $36 per week and the prices of the two goods are unchanged at Px= $1.5 and Py= $1. d) Use your demand functions to find his new best bundle. e)…

To help with his busy schedule, Joe drinks a lot of cappuccinos. In particular, his weekly demand for cappuccinos is: cap = 0.1 M-8 Pcap Where Xcap is the number of cappuccinos drunk per week, Mis Joe's weekly income and Pcap is the price of a cappuccino. (Note that Xcop is an average demand and need not be a whole number). (a) Suppose that income M = 240 euro, and the price is Pcap = 1.5 euro. How many Cappuccino, on average, will Joe drink per week? Suppose that the price increases to Pcap = 1.6 euro. (b) What is Joe's new demand for cappuccinos? What is his total change in demand due to the price change? (c) Given the new price (Pcap = 1.6), how much extra income would Joe need to allow him to continue buying the number of Cappuccinos calculated in part (a), without needing to reduce his demand other goods? (In other words, how much would Joe's expenditure on cappuccinos have gone up if he had continued to buy the number of cappuccinos calculated in part (a)?) (d) Compute the change…
