Robin consumes two goods X and Y. His utility function is given by U(x, y) = x*y. The price of Good X used to be $10 per unit but has recently increased to $20 per unit due to the good being taxed. The price of Good Y has remained unchanged at $20 per unit. Robin has $2000 to spend. Suppose the government wants to give Robin enough money so that he can still consume the amount of X and Y that he was consuming before the price change. Which of the following statements is CORRECT? O At the earlier prices, Robin would consume 75 units of X and 100 units of Y. This bundle now costs $2750. But if the government gave Robin an additional $750 then Robin would prefer to consume 80 units each of X and Y. O At the earlier prices, Robin would consume 50 units of X and 100 units of Y. This bundle now costs $2500. So, the government needs to give Robin an additional $500 to afford the original bundle. But if the government gave Robin an additional $200 then Alex would prefer to consume 100 units each of X and Y. O At the earlier prices, Robin would consume 200 units of X and 50 units of Y. This bundle now costs $3000. So, the government needs to give Robin an additional $1000 to afford the original bundle. But if the government

Bruno can spend his income on two different goods: smoothies and energy bars. For each of the following three situations, decide if the given consumption bundle is within Bruno’s consumption possibilities. Then decide if it lies on the budget line or not. Smoothies cost $2 each, and energy bars cost $3 each. Bruno has income of $60. He is considering a consumption bundle containing 15 smoothies and 10 energy bars. Smoothies cost $2 each, and energy bars cost $5 each. Bruno has income of $110. He is considering a consumption bundle containing 20 smoothies and 10 energy bars. Smoothies cost $3 each, and energy bars cost $10 each. Bruno has income of $50. He is considering a consumption bundle containing 10 smoothies and 3 energy bars.
Jasper utility function for beer and pizza can be expressed as: U(B,P) = BXP Suppose beer costs $5 per glass, pizzas cost $10 each, and Jasper has a total of $30 to spend. Assume Jaspeer is allowed to purchase fractional amounts of each good. Part A) Based on the above information, what is Jaspeer's optimal amount of beer? Enter the number below. glasses Beer = 3 Part B) Now suppose the price of beer falls from $5 down to $3. Calculate the following and fill in the blanks below. When necessary, round answers to two places after the decimal. (Hint: find the decomposition basket to calculate the substitution and income effects). Jasper's total effect on beer is to increase total consumption by glasses of beer. Jasper's substitution effect is to increase beer consumption by 0.28 Jasper's income effect is to increase beer by 1.12 glasses of beer. glasses of beer.
A consumer has a budget set aside for entertainment during the year, and they spend the budget on concerts and plays. The consumer has a strong preference for attending concerts over plays: the two activities are substitutes, but not very strong substitutes. Sketch the indifference curves for this consumer on a graph, with concert tickets on the vertical axis and play tickets on the horizontal axis. Briefly explain why the consumer might ultimately choose to purchase a large number of play tickets, even though they have a strong preference for concerts. Include a budget line on your graph to illustrate this case.
Julie, who has $64, consumes only two goods: whistles (w), which cost $6 each and xylophones (x), which cost $7 each. Her preferences over these two goods can be represented by the utility function u(w, x) = 3w0.75 0.25 a) What is the optimal number of whistles for Julie to consume given this scenario? b) What is the level of utility Julie attains at this level of consumption? c) Suppose now that the price of whistles rises from $6 to $7. What is the magnitude of this price effect on whistles?

Floyd's utility function is given by U(X,Y)=2XY. MUx=2Y and MUy-2X. The price of good X is Px=2, while the price of good Y is Py = 1. Floyd's income is 1,000. Which of the following is true given that the price of good X falls to 1? The substitution effect for good X results in an increase of X consumption by about 1,043 units and a decrease in Y consumption by about 14 units. The substitution effect for good X results in X consumption of about 250 units. The substitution effect for good X results in X consumption of about 500 units. The substitution effect for good X results in an increase of X consumption by about 250 units and no change in Y consumption.
A consumer is in equilibrium at point A in the accompanying figure. The price of good X is $5. At point A, how many units of good X does the consumer purchase? Suppose the budget line changes so that the consumer achieves a new equilibrium at point B. What change in the economic environment led to this new equilibrium? Is the consumer positively or negatively affected by the price change?

Explain whether the following statement is true, false, or uncertain. A consumer consumes two categories of goods x and y. If an increase in the price of y does not increase the consumer's consumption of x, then this consumer must consider x to be an inferior good.
Smith and Jones are stranded on a desert island. Each has in her possession some slices of ham (H) and cheese (C). Smith prefers to consume ham and cheese in the fixed proportion of 2 slices of cheese to each slice of ham. Her utility function is given by Us = min(10H, 5C). Jones, on the other hand, regards ham and cheese as substitutes – she is always willing to trade 3 slices of ham for 4 slices of cheese, and her utility function is given by UJ = 4H + 3C. Total endowments are 100 slices of ham and 200 slices of cheese. a. Draw the Edgeworth Box diagram for all possible exchanges in this situation. What is the contract curve for this exchange economy? b. Suppose Smith’s initial endowment is 40 slices of ham and 80 slices of cheese (Jones has the remaining ham and cheese as her initial endowment). What mutually beneficial trades are possible in this economy and what utility levels will Smith and Jones enjoy from such trades? c. Now imagine a new endowment in which Smith has 60 slices…
