Louis F. Post,
The basic facts of economics
(1927)
“ But division of Labor would be useless were it not for Trade. Each of those frontiersmen must trade his share in the other’s habitation for the other’s share in his habitation; each of those messengers must exchange his claim to compensation for delivering one of the other’s two messages for the other’s claim to compensation for delivering one of his. This, then, is the sum and substance of Trade in Economics—adjustments of compensation for specialized Production through division of Labor. ”
