One of the things I like about talking (or, in this case, "talking") to economists is that it often turns out that life's little mysteries have answers. Maria Farrell, for example, had an eloquent post complaining about how airport shops don't seem to offer the goods that one would actually want to buy in an airport. Tyler Cowen comes along with a plausible, yet convincing, account of why these things shake out the way they do.
