Monkey business

In Introductory Microeconomics, we have been discussing trade. We all know that Adam Smith wrote that trade was a result of people’s “propensity to truck, barter, and exchange one thing for another.” But did you know that he also wrote “Nobody ever saw a dog make a fair and deliberate exchange of one bone for another with another dog. Nobody ever saw one animal by its gestures and natural cries signify to another, this is mine, that yours; I am willing to give this for that.” (Wealth of Nations, Book I, Chapter II) This video calls all of that into question, it would seem (thanks to Adam King). On a related note, listen to this podcast from NPR to get an interesting perspective on early trade (thanks to Max Randolph).
