Without having ever taken any course on math or real analysis...How is it possible?
I have seen their papers, and they don't use any math at all...!!! And some of them are RePEc moderators.
So, how they teach their grad students? However, their papers are original and not too bad, maybe worth reading.
This is seen mostly in EU, Italy and, UK and France. But not in Germany or the US.
Please explain, why am I studying math then?
