Question
Anna is indifferent between bread and rolls for her sandwiches. She believes that 2 slices of bread is always just as good as 1 roll. Let bread be the x-good measured in slices and rolls be the y-good measured in number of rolls. Suppose Anna has $1 to spend on bread and rolls.
- a) Given our assumptions on preferences and the information above, Illustrate indifference curves that represent Anna's preferences. What is her MRS?
- b) If the
price of a slice of bread is $.10 and the price of a roll is $.25 then what bundle will she choose? Show that her MRS is not equal to the price ratio at that bundle. Illustrate your answer in your diagram for part (a). - c) If the price of a slice of bread rises to $.20 then what bundle will she choose? Show that her MRS is not equal the price ratio at that bundle. In a new diagram illustrate her best bundle.
- d) Briefly explain why her MRS is not equal to her best bundles in parts (b) and (c).
