This is supposed to be a very simple post, mainly for non-economists.
"Printing money causes inflation" can mean three different things. What I will say here should be obvious to economists, but I'm not sure if it is obvious to non-economists. And it makes me wonder if sometimes things get lost in translation. Maybe, just maybe, some people are strongly opposed to central banks printing very large amounts of money because they misunderstand "printing money causes inflation". Who knows? Tell me what you think.
Those of us who teach Intro Economics know we have to spend some time carefully explaining the "other things equal" clause, and why it matters. Because the students won't get it unless we explain it. We tend to take it for granted that the silent "other things equal" clause is understood, but it might not be understood by all.
