A student is trying to find out. He emails me:
a 1st year MBA student at Chicago Booth -- where even the Marketing Professors
have a PhD in Economics.
taking a class this quarter called Entrepreneurial Selling (more info here). One of the coolest assignments is a bartering
challenge: Prof. Wortmann gives everybody a simple Chicago Booth pen and we need
to barter it for something with larger monetary value, and then keep bartering
once a week until the end of the quarter.
I did my first trade with Prof. Lars Peter
Hansen (Economics Nobel Prize 2013). In exchange for my pen, he gave me an
autographed copy (he wrote a cool anecdote as well) of his most famous article.
I'm now running an auction at eBay (it's OK to trade things for cash): see here.
