A story from Davos, and how Grumpy got his name

I was reading Nick Paumgarten's New Yorker article about Davos in the bathtub this morning, and ran into this gem:

The Belvedere [hotel], ... is the annual meeting’s hub after dark. Often, there are a half-dozen parties going on at once. To get into it,...you must pass through airport-like security ... The line, on this night, was long enough that a Nobel laureate in economics, who, moments earlier at the Hotel National, had been holding forth on unfairness, deemed it worth cutting. 

It would be easy enough to figure out who it was, but I like the story better as it is, a reflection on the Davos attitude, not a snarky comment on one individual. (If you know, please don't run it by outing him in the comments.) 
 
A while back, on a lovely spring night, I was walking home with my family after dinner out. We observed one of Hyde Park's Great Liberal Minds, walking his ill-trained dog. He watched his dog deliver a a large steaming poop, and walked off, leaving the poop behind.

I opined, "well, there goes the Great Liberal; I suppose he thinks there is a Federal Department of Picking up your Dog Poop."

The kids laughed and dubbed me "Grumpy Economist" on the spot.

Update: I removed a few comments. I really do not want this to be personal.
