Anthony spends all his income on two goods, X and Y and his tastes don't change between 2008 and 2009. The prices he paid and the quantities he consumed in 2008 are as follows: PX = 15, X = 20, PY = 25 and Y = 30. Suppose the prices in 2009 are PX = 6 and PY = 30, and his income in 2009 is €1,020,
Anthony is as well off in 2009 as he is in 2008
Anthony is better off in 2009 than in 2008
Anthony is better off in 2008 than in 2009

Megan
is a college student who consumes food and transportation. Last year, she consumed 90 meals and purchased 100 gallons of gasoline per month. Suppose that last year the price of a meal was
$5
and the price of a gallon of gasoline was
$2.23.
However, this year, the price of a meal is
$6
and the price of a gallon of gasoline is
$3.92.
As a result,
Megan
consumes 100 meals and 80 gallons of gasoline. For this example, assume
Megan's
utility this year is the same as her utility last year (and that her preferences have not changed).
Calculate a Laspeyres cost-of-living index for
Megan
using 100 as the base for last year. In particular, the Laspeyres index for this year is
nothing.
(Enter
your response rounded to two decimal

- Joyce consumes x1 and x2 together in fixed proportions. She always consumes 1 unit of x2 for 2 units of x1. What is the utility function that describes her preference?arrow_forwardSienna gets a total of 20 utils per week from her consumption of pizza and a total of 40 utils per week from her consumption of yogurt. The price of pizza is $1 per slice, the price of yogurt is $1 per cup, and she consumes 10 slices of pizza and 20 cups of yogurt each week. Which of the following statements is correct regarding Sienna's current consumption of pizza and yogurt? Sienna should eat more yogurt and less pizza, as she is getting more utils from the $20 spent on yogurt than from the $10 spent on pizza. Sienna should eat more pizza and less yogurt, as she is getting more utils from her last dollar spent on pizza than her last dollar spent on yogurt. We cannot determine if Sienna is maximizing her total utility with the information provided. Sienna should eat more yogurt and less pizza, as she is getting more utils from her last dollar spent on yogurt than her last dollar spent on pizza.arrow_forwardQ43 Laurie spends all of her money buying bread and cheese.

- 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.

- Linda loves buying shoes and going out to dance. Her utility function for pairs of shoes, S, and the number of times she goes dancing per month, T, is U(S + T) = 2ST, so Mus = 2T and Mut = 2S. It costs Linda $50 to buy a new pair of shoes or to spend an evening out dancing. Assume that she has $500 to spend on shoes and dancing What is the equation for her budget line? Draw it (with T on the vertical axis), and label the slope and intercepts. What is Linda’s marginal rate of substitution? Explain. Use math to solve for her optimal bundle.

Because he likes only peanut butter and jelly sandwiches, he spends the entire amount on peanut butter (at $.05 per ounce) and jelly (at $.10 per ounce). Bread is provided free of charge by a concerned neighbor. Ebrima is a picky eater and makes his sandwiches with exactly 1 ounce of jelly and 2 ounces of peanut butter. He is set in his ways and will never change these proportions. How much peanut butter and jelly will Ebrima buy with his $3 allowance in a week? Suppose the price of jelly were to rise to $.15 per ounce. How much of each commodity would be bought? By how much should Ebrima’s allowance be increased to compensate for the rise in the price of jelly in part b? Graph your results of part a through part c. In what sense does this problem involve only a single commodity—peanut butter and jelly sandwiches? Graph the demand curve for this single commodity. Discuss the results of this problem…arrow_forward
