Terry

has a comparative advantagefishing, and Robin

has a comparative advantage gathering coconuts.

Suppose that each person is initiallyself-sufficient. In asix-day week, Robin produces and consumes 32

32 coconuts and 4fish, and Terry produces and consumes 4 coconuts and 2 fish.

Now suppose Robin and Terry engage in specialization andexchange, trading 2

2 coconuts for 1 fish.

If Robin and Terry consume the same number of fish as in theself-sufficient outcome, then specialization and exchange allow Robin to consume

nothing
