You Have a Book Publishing Company

You have a book publishing company. You own a paper mill, a printing operation, and a bindery. Within your firm you produce the paper for your books, print the manuscripts, bind the finished product, edit the authors' work, and sell the books. You refuse to deal with any companies that could supply you these services. What problem(s) do you most likely have with the antitrust laws? You face:

A) treble damages claims under the Sherman Act for horizontally restraining trade
B) only minor problems because your operations are relatively small
C) possible criminal penalties under the Clayton Act for conspiring to dominate a market
D) violation of the Robinson-Patman Act
E) none of the other choices
