WASHINGTON — The Microsoft Corp. antitrust trial recessed 13 weeks ago with fireworks over the credibility of Microsoft executives whose actions are disputed in the case. Tuesday’s testimony returned the case to its technical antitrust core — a battle of dueling economists.
Taking the stand Tuesday morning for the Justice Department was Franklin Fisher, an economics professor at the Massachusetts Institute of Technology’s Sloan School of Business. He wasted no time rebutting the assertions of his opposite number on the Microsoft team, Richard Schmalensee, the Sloan School’s dean and his former student.
