Partial Specialisation Is Enough

The idea
The gains do not require either country to abandon a good entirely. Shifting some workers toward the comparative advantage raises combined output, and the more that shifts, the larger the gain.
In practice
A partial shift produces a partial gain, in the same direction.
Where people slip
Full specialisation is the clean case in the arithmetic, not a requirement of the argument.
