I got an email from a participant at the Center for Popular Economics 2011 Summer Institute, which I was fortunate enough to be able to teach. It was, as always a crazy busy, exciting week. The question concerned growth: whether I thought growth was necessary, and how it is related to employment. It's a pretty big question. In economics, the questions don't get much bigger. So I promised to write a blog post to give my answer. And this is that blog post. I will do my best to answer broadly, simply, and, I hope, intelligibly for any audience no matter how much or how little economics they may have been subjected to previously.
