Still, Adam Smith really did seem to believe barter was real. He writes, “When the division of labour first began to take place, this power of exchanging must frequently have been very much clogged and embarrassed in its operations,” and then goes on to describe the inefficiencies of barter. And Beggs says that many textbooks sloppily seem to endorse this viewpoint. “They sort of use that fairy tale,” he explains.
Economic historian Karl Polanyi has argued that where barter is widespread, and cash supplies limited, barter is aided by the use of credit, brokerage, and money as a unit of account (i.e. used to price items). All of these strategies are found in ancient economies including Ptolemaic Egypt. They are also the basis for more recent barter exchange systems.
Although, as a general case, a ship unlucky in falling in with whales continues to cruise after them until she has barely sufficient provisions remaining to take her home, turning round then quietly and making the best of her way to her friends, yet there are instances when even this natural obstacle to the further prosecution of the voyage is overcome by headstrong captains, who, bartering the fruits of their hard-earned toils for a new supply of provisions in some of the ports of Chili or Peru, begin the voyage afresh with unabated zeal and perseverance.
