TraditionInAction is very critical of distributism. I don't find their criticism convincing:

Distributism seems like Catholic principles, especially papal encyclicals of Social Teaching, applied to society and economics.

Google around also for info on the "Catholic Land Movement" which was tied to Distributists.

Catholic Social Teaching vs. Libertarian economists:

Definitions of distributism seem to vary, but it seems to be the attempt to "distribute property as widely as possible".

The dominant economic schools seem to be Austrianism vs. Keynesianism: another battle of false alternatives, in my opinion.

How the money power created Austrianism:

Church History by Tan Books said: "The early disciples practiced a species of communism". This, of course, was not to endorse communism, which is condemned, but I found it interesting that they used this exact phraseology. The key difference was that the sharing was voluntary, of course.

I don't think the Church has a set "ism" for economics according to Catholic Action books I've seen, besides excluding that which it condemns officially like atheistic Communism. I think distributism gets more at how a Catholic economy should look like under Christendom.
