JAPANESE CORPORATE EARNINGS RECOVERY PREDICTED Japanese corporate earnings will rise 8.9 pct in fiscal 1987/88 for the first year-on-year increase in three years, partly because of the yen's stable exchange rate, the Nomura research institute said. Sales of all industries are predicted to rise 1.9 pct in the year, which starts April 1, the research arm of Nomura Securities Co said in a statement. Recurrent profits were estimated to fall 20 pct in the current fiscal year with sales forecast to drop 14 pct. The forecast assumes an average rate of 148.5 yen to the dollar in 1987/88, compared with 160 yen in the current year. Corporate efforts to cope with the yen's appreciation, such as cutting production costs, are expected to bear fruit next fiscal year, the institute said. The economy should also benefit from pump-priming expected from the government and a halt in rising prices of manufactured goods, it said. Recurrent profits of manufacturing industries are projected to rise 29.6 pct next fiscal year against an estimated 40.1 pct fall in the current year. Non-manufacturing sector profits will decline 4.5 pct in 1987/88 against an estimated 2.2 pct rise in the current year, it said.
