Wendy's CEO Kerrii Anderson hopes new items will spur sales

Wendy's International Inc is aiming to roll out inexpensive sandwich wraps and a new hamburger to increase sales as the U.S. economy weakens, Chief Executive Kerrii Anderson said on Tuesday. "The consumer environment from a year ago has changed drastically,"she said. "I am very concerned about the consumer overall and their confidence level." The restaurant industry is being squeezed by higher ingredient costs while U.S. customers grapple with higher gasoline and food costs and concerns about falling home values and the possibility of recession.
