Moneyball, UPS Delivery, and the Magic of Better
This article was previously published in October 2011. I am moving past blog archives to this site. Recently I watched the movie Moneyball, and thought about what it might mean for quantitatively-minded people. (Note: For the purpose of simplicity, I’ll temporarily pair together quantitatively-minded and operations research, although not everyone in one group would claim…
Read MoreMy Personal Debt to John Nash
Why did I even take Economics as a freshman engineering major at Youngstown State? It was a sort of happy accident, but there I was, surrounded by business majors, in Microeconomics*.

The reward might be $2 per ratings point (where…
