“[E]very once in a while, someone builds a theoretical model of a violation of the law of demand. Sometimes, they even include an investigation of one such good that seems to break the law of demand. But, upon further investigation, such examples break down, and the law of demand holds true. Strong evidence is needed for strong claims. I think of this exam question whenever I read some economic commentator claiming that international trade has weakened America. Such an outcome would be unprecedented. Millennia of experience and evidence suggest trade strengthens nations and that turning away from it weakens them.” (11/14/25)
