San Diego, June 7 (BridgeNews) - The U.S. economy should be able to reach a GDP growth rate of up to 3.5% by 2002, Federal Reserve Bank of San Francisco President Robert Parry said. But Parry said he was unsure whether the U.S. would soon experience back-to-back growth rates of 4% or better like in recent years. He said it is likely to be some time before Federal Reserve interest rate cuts since the beginning of this year work their whole effect on the economy.
