Ben allocates his lunch budget between two goods, pizza, and burritos.

a. Illustrate Ben’s optimal bundle on a graph with pizza on the horizontal axis.

b. Suppose now that pizza is taxed, causing the price to increase by 20 percent. Illustrate Ben’s new optimal bundle.

c. Suppose instead that pizza is rationed at a quantity less than Ben’s desired quantity. Illustrate Ben’s new optimal bundle.

Step by step solution

01

Ben’s optimal consumption bundle for lunch

Ben consumes pizza and burritos for lunch. His optimal consumption bundle (P1, B1) is shown in the following diagram.

The optimal consumption bundle is the point of tangency of the indifference curve with the budget line.

02

Effect of tax on Ben’s budget line

Pizza becomes costly when government taxes are imposed. Ben’s budget line will shift due to the price rise after taxes.

Ben’s optimal consumption bundle shifts to a lower indifference curve shown in the above figure. The new consumption bundle will be (P2,B2).

03

Consumer’s indifference curve during rationing

Rationing is the government’s action for controlled product distribution rather than allowing prices to increase to competitive levels.

Pizza is rationed at quantity less than the desired (Ben’s optimal consumption bundle) quantity; the indifference curve shifts downward.

The above figure shows the indifference curve, which is below Ben’s budget line. His rationed consumption bundle (P3, B3) will lie on the indifference curve below the initial indifference curve (shown in dotted lines).

The utility that Meredith receives by consuming food F and clothing C is given by U(F,C) = FC. Suppose that Meredith’s income in 1990 is \(1200 and that the prices of food and clothing are \)1 per unit for each. By 2000, however, the price of food has increased to \(2 and the price of clothing to \)3. Let 100 represent the cost of living index for 1990. Calculate the ideal and the Laspeyres cost-of-living index for Meredith for 2000. (Hint: Meredith will spend equal amounts on food and clothing with these preferences.)

Brenda wants to buy a new car and has a budget of \(25,000. She has just found a magazine that assigns each car an index for styling and an index for gas mileage. Each index runs from 1 to 10, with 10 representing either the most styling or the best gas mileage. While looking at the list of cars, Brenda observes that on average, as the style index increases by one unit, the price of the car increases by \)5000. She also observes that as the gas-mileage index rises by one unit, the price of the car increases by \(2500.

a. Illustrate the various combinations of style (S) and gas mileage (G) that Brenda could select with her \)25,000 budget. Place gas mileage on the horizontal axis.

b. Suppose Brenda’s preferences are such that she always receives three times as much satisfaction from an extra unit of styling as she does from gas mileage. What type of car will Brenda choose?

c. Suppose that Brenda’s marginal rate of substitution (of the gas mileage for styling) is equal to S/(4G). What value of each index would she like to have in her car?

d. Suppose that Brenda’s marginal rate of substitution (of the gas mileage for styling) is equal to (3S)/G. What value of each index would she like to have in her car?

Anne has a job that requires her to travel three out of every four weeks. She has an annual travel budget and can travel either by train or by plane. The airline on which she typically flies has a frequent-traveler program that reduces the cost of her tickets according to the number of miles she has flown in a given year. When she reaches 25,000 miles, the airline will reduce the price of her tickets by 25 percent for the remainder of the year. When she reaches 50,000 miles, the airline will reduce the price by 50 percent for the remainder of the year. Graph Anne’s budget line, with train miles on the vertical axis and plane miles on the horizontal axis.

Jane receives utility from days spent traveling on vacation domestically (D) and days spent traveling on vacation in a foreign country (F), as given by the utility function U(D,F) = 10DF. In addition, the price of a day spent traveling domestically is \(100, the price of a day spent traveling in a foreign country is \)400, and Jane's annual travel budget is $4000.

a. Illustrate the indifference curve associated with a utility of 800 and the indifference curve associated with a utility of 1200.

b. Graph Jane's budget line on the same graph.

c. Can Jane afford any of the bundles that give her a utility of 800? What about a utility of 1200?

*d. Find Jane's utility-maximizing choice of days spent traveling domestically and days spent in a foreign country.

Suppose that Jones and Smith have each decided to allocate $1000 per year to an entertainment budget in the form of hockey games or rock concerts. They both like hockey games and rock concerts and will choose to consume positive quantities of both goods. However, they differ substantially in their preferences for these two forms of entertainment. Jones prefers hockey games to rock concerts, while Smith prefers rock concerts to hockey games.

a. Draw a set of indifference curves for Jones and a second set for Smith.

b. Using the concept of the marginal rate of substitution, explain why the two sets of curves are different from each other.
