Transcribed Image Text:Exercise 2
Juliette spends $48 each month on salt and vinegar chips (which cost $3
per bag) and Oreo cookies (which cost $2 per package). Her preferences for these two goods are
represented by "convex" indifference curves.
a) With chips on the horizontal axis, draw Juliette's budget line, making sure to indicate the
horizontal and vertical intercepts.
b) Suppose that at current prices, Juliette purchases 6 bags of chips each month (assume
Juliette is maximizing her utility). Sketch an indifference curve tangent to Juliette's
budget line consistent with this choice and her preferences. Label her chosen bundle with
the letter A. How many packages of Oreos does Juliette buy?
c) Suppose that the price of chips falls to $2 per bag, and Juliette increases her chip
consumption to 8 bags each month. On the same graph, draw Juliette's new budget line
and sketch an indifference curve consistent with her new choice and her preferences. Label
her utility-maximizing bundle with the letter B. How many packages of Oreos does
Juliette buy now?
d) A major chip producer has experienced a fire, and the disruption of supply has caused the
price of chips to increase to $4. As a result, Juliette cuts her consumption of chips to 5 bags
per month. On the same graph, draw Juliette's new budget line and indicate her chosen
bundle with an appropriately drawn indifference curve. Label her new utility-maximizing
bundle with the letter C. How many packages of Oreos does Juliette buy now?
e) On the same graph, draw Juliette's price-consumption curve.
f)
On a separate graph, draw Juliette's demand curve of chips using your answers from
parts (b) (d). Explain how Juliette's chips consumption is affected by a change in price.
IMPORTANT: For parts (a)-(d) be sure you use a graph panel with a consistent scale. As a
reference, you can use the template shown in the last page of this problem set. I'll print copies
of the template and leave them at my door box. Feel free to stop by and pick one!
