The National Bureau of Economic Research doesn’t sound like the type of institution that would bother with the study of baseball cards and card conventions, but a newly released study did exactly that.
The economists who wrote the paper — Ginger Zhe Jin of the University of Maryland and Marc Rysman of Boston University — somehow got ahold of data on sports card shows dating back to the 1980s and studied them from the perspective of a two-sided market.
They also looked at what happened to shows as sports card transacting went online.
The New York Times checked out the study and checked in with a couple of dealers, too. It paints a fairly good and accurate picture of the industry.

Keep in mind it’s an academic type study so don’t expect breezy reading.
