Hello Everyone-
I’m Elaine.
Having been in the classroom for decades, written three books (and some of a fourth one), I like to think about economics everywhere all the time. Every day, I’ve added a blog to econlife—now it has been almost 14 years and more than 4,000 posts. I am delighted that you are here and hope we can have some economic fun together.
