The AT&T-Time Warner merger could end up costing consumers less money than what some earlier estimates suggest, the government's star witness admitted in federal court Tuesday as he clashed repeatedly with company lawyers over key figures in his economic analysis of the deal.

Instead of paying a minimum of 27 cents more per month on their bills as a result of the deal, TV subscribers could conceivably pay a smaller premium of at least 13 cents a month more — a downward revision in the projections of Carl Shapiro, an economist at the University of California–Berkeley. Toward the other end of the range, the government has said consumers could pay as much as 45 cents more per month on their bills, or collectively hundreds of millions of dollars a year.
