WOJNILOWER SEES DROP IN U.S. INTEREST RATES The Federal Reserve will promote lower interest rates this year to sustain world economic growth, First Boston Corp managing director Albert Wojnilower said. As much as the Fed would like to take a tough line against inflation, it cannot act to slow the growth of credit without subverting national U.S. economic policy. "On selected occasions when the dollar seems steady, and, because the trade deficit is not responding, the United States decided to push Germany and Japan harder to meet their commitments to economic growth, the Federal Reserve will do its part by moving rates down," Wojnilower said in a report. "Justifiably not anticipating either a recession or seriously higher interest rates, securities market participants have seen little to fear," Wojnilower said. He said last week's "hiccup" in money and currency rates and bond and stock prices was probably caused by Japanese window dressing for March 31 end-of-fiscal-year accounts. Wojnilower said the U.S. probably enjoyed above-average economic growth in the first quarter. However, the pick-up seems to reflect an unsustainable pace of inventory building and the prospect for the full year is still for real gross national product growth of about 2-1/2 pct, he said.
