The government argued Monday that U.S. consumers would pay 5 percent more for ranges and wall ovens if AB Electrolux (ELUXb.ST) was allowed to buy General Electric’s (GE.N) appliance business but the companies accused antitrust enforcers of failing to acknowledge powerful and growing competition from overseas manufacturers. The Department of Justice asked a federal court in July to stop Sweden’s Electrolux, which makes Frigidaire, Kenmore and Tappan appliances, from buying GE’s appliance business for $3.3 billion.
