The people who run it are in the cost-allocation business, not the maximizing-utility business.
There is a push to get jstor access for every AEA member. Dale Jorgenson heads a committee. Rumors are that Jorgenson will this spring recommend that the AEA purchase jstor access for its members for $15 a year each--but that if more than 2,500 sign up, then the AEA will get a volume discount and everyone will get their own personal userid/passwd.
But I haven't talked to anyone on the AEA executive committee about this: this is a third-hand rumor...
