Suppose Naomi consumes two goods: good 1 and good 2. Last year, the price of good 1 was $2.00 and the price of good 2 was $3.20. Given these prices, Naomi maximized satisfaction consuming bundle A, as indicated in the figure to the right. However, this year, the price of good 1 has increased to $6.00 and the price of good 2 has changed to $2.40. Given these prices, Naomi would be equally well off at consumption bundle B. Calculate a Laspeyres cost-of-living index for Naomi using 100 as the base for last year. In particular, the Laspeyres index for this year is ☐. (Enter your response rounded to two decimal places.) The Laspeyres index suggests inflation has been percent over the year. (Enter your response rounded to two decimal places.) The Laspeyres cost-of-living index overstates the rate of infle

Bottles of water sell for 1 euro and slices of chocolate cake sells for 3 euros. Suppose Jack, whose preferences satisfy all of the basic assumptions of consumer choice theory, buys 5 bottles of water and one slice of chocolate cake every day. At this consumption bundle, his MRS of bottles of water for slices of chocolate cake is 3 (i.e. he is willing to give up 3 bottles of water to get an additional slice of cake). Which of the following is true? (Hint: draw this situation with bottles of water on the vertical axis and slices of cake on the horizonal axis). A. Jack could increase his utility by buying fewer bottles of water and more slices of cake. B. Jack could increase his utility by buying more bottles of water and less chocolate cake. C. Jack could not increase his utility because it is already at a maximum level. D. Jack could increase his utility by buying more bottles of water and more chocolate cake.
R2) The only fruits Dana buys are apples (x) and/or berries (y). She spends $30 on fruits per month. Her utility for fruits is given by u = 4y+xy, with marginal utilities MUxy and MU, 4+x. The price of apples is Px=$1 and the price of berries is Py = $2. a) Draw her budget line (BL) in a diagram. Show the calculations needed to do so. (Your graph does not need to have accurate scale- simply indicate the relevant values in each axis of the graph). b) In the same diagram, draw her indifference curve (IC) for a utility level of 100. Show the calculations needed to do so. (Hint: Find the combinations on the IC for x=1, x=6, x=16). c) Graphically (without using the mathematical method), find her optimal choice (x,y*). Explain in words how we figure out the optimal choice using the budget line and indifference curves only.

The tables show the utility Parker experienced from consuming varying quantities of waffles and pancakes. Assume that waffles cost $2.00 each, pancakes cost $1.00 each, and that Parker has $8.00 to spend on these two goods. Since Parker cannot afford more than four waffles or eight pancakes, the utility is given only for quantities smaller than these. Quantity of waffles Total utility of waffles Marginal utility of waffles 1 100 100 2 180 80 3 240 60 4 270 30 Quantity of pancakes Total utility of pancakes Marginal utility of pancakes 1 40 40 2 70 30 3 90 20 4 105 15 5 115 10 6 120 5 7 123 3 8 125 2 Given his budget constraint, determine what quantities of waffles and pancakes Parker will consume to maximize utility. quantity of waffles: waffleswaffles quantity of pancakes: pancakes
Rohan’s current marginal utility from consuming peanuts is 100 utils per ounce and his marginal utility from consuming cashews is 200 utils per ounce. If peanuts cost $0.10 per ounce and cashews cost $0.50 per ounce, is Rohan maximizing his total utility from the kinds of nuts? Enter your responses as whole numbers. At the current level of peanut consumption, Rohan receives: utils per dollar.At the current level of cashew consumption, Rohan receives: utils per dollar.Therefore, Rohan maximizing his total utility because MUp/Pp is MUc/Pc.
Mike is a jellyfish wrangler. In June and July he spent his budget on fish tanks and wet suits. Each fish tank cost $50 and each wet suit cost $100. At Mike's optimal choice, his marginal utility from the last fish tank purchased is 200. This means that his marginal utility from the last wet suit purchased is:

7. MRS and utility maximization Suppose your classmate Felix loves to eat dessert-so much so that he allocates his entire weekly budget to apple crisp and pie. The price of one bowl of apple crisp is $1.75, and the price of a piece of coconut crème pie is $7.00. At his current level of consumption, Felix's marginal rate of substitution (MRS) of apple crisp for pie is 5. In other words, Felix is willing to sacrifice five bowls of apple crisp for one piece of pie per week. Does Felix's current consumption bundle maximize his utility? That is, does it make him as well off as possible? If not, how should he change it to maximize his utility? Felix could increase his utility by buying more apple crisp and less pie per week. Felix could increase his utility by buying less apple crisp and more pie per week. Felix's current bundle maximizes his utility, and he should keep it unchanged.
Joyce drinks both coffee (x) and tea (y). Her preferences over these two goods can be represented by the utility function U(x,y) =x + 3y^1/2 where x represents the number of pounds of coffee and y represents the number of cups of tea. a) Given her preferences, find her demand functions for coffee (x) and tea (y). b) Suppose that the price of a pound of coffee is $4 and that she has $56 to spend on coffee and tea. Write her demand curve for tea. Illustrate her demand curve. c) Suppose that the price of a cup of tea is $1 (the price of coffee and income remain $4 and $56, resp.). Use your demand functions to find her best bundle. In an indifference curve diagram illustrate her best bundle at these prices. For the remainder of the question, assume that her income rises to $60 and that the prices of coffee and tea are unchanged at = $4 and =1.
