Suppose that one day, Gilligan (the castaway) eats a
magical island plant that turns him into an expert at
everything. In particular, it now takes him just half
an hour to pick a quart of berries, and 15 minutes to
catch a fish.
a. Redo Table 2 in the chapter.
b. Who—Gilligan or Maryanne—has a comparative
advantage in picking berries? In fishing?
c. Suppose that Gilligan reallocates his time to
produce two more units of his comparative
advantage good, and Maryanne does the same.
Construct a new version of Table 3 in the chapter
showing how production changes for each castaway, and for the island as a whole.
