I am sure that telemarketers and tv evangelists are willing to pay big money for lists of gullible people. I am going to give you a similar list for free, a list of libraries that apparently are either almost entirely inattentive to cost or have so much money that they don't know what to do with it.
Two obscure economics journals, the Journal of Economic Studies and the International Journal of Social Economics are each priced at more than $7500 for the 2001 volume. The third most expensive economics journal costs about $2400 per year. In contrast, the six most-cited economics journals cost an average of $180 per year. The world's two most expensive journals are NOT the wqrld's two best journals. Not even close. In fact, most economists haven't heard of either one. They are rarely cited in scholarly work and are not even included among the journals from which Social Science Citation Index counts citations.
As you might expect, there are not many takers at these prices. The remarkable thing is that there are some. The following universities are recorded by the OCLC union list of library catalogs as having current print subscriptions to the two most expensive economics journals in the world. (Harvard is not inventoried by OCLC, but current copies of these two journals are listed in the online Harvard library catalog.) I have discovered that some libraries listed by the OCLC as having these journal have already canceled their subscriptions but didn't get around to notifying the OCLC. I have removed their names from this page.
Quite possibly, most of the libraries on this list are getting these journals as part of a bundle at a lower price than the price listed by the publisher. As more details arrive, I will report them.
I would be delighted to hear an explanation from anyone at any of these universities of why they are spending money on these journals.
