Economics professors be like: "Tariffs? Bad. But have you seen what happens when elasticity goes negative?!" *shocked Spongebob eyes*
That moment when your trade model breaks the fabric of economic reality. In economics, elasticity (ε) is supposed to be negative - it measures how demand drops when prices rise. If ε>0, you've basically created a universe where people buy MORE stuff when it gets MORE expensive. Next thing you know, students are paying extra for textbooks voluntarily and the Federal Reserve is hiring meme creators for policy advice.
