WASHINGTON — As the Justice Department prepares to battle Apple Inc. over alleged price-fixing in the electronic books market, top department officials said Wednesday they are hopeful consumers will benefit from the settlement reached with three publishers.

Sharis Pozen, the acting head of the DOJ Antitrust Division, said the government believes the settlement with three publishers — HarperCollins Publishers LLC, Simon & Schuster Inc. and Hachette Book Group Inc. — will restore price competition and lead to lower prices for e-books.
