GERMAN INSTITUTE SEES INFLATION RISING IN 1987 The cost of living in West Germany will likely be about 0.5 pct higher on average in 1987 than in 1986, when the cost of living actually fell by an average 0.2 pct in the first recurrence of "negative inflation" since the 1950s, the HWWA economic research institute said. The re-emergence of inflation will result mainly from the fading of two factors which influenced the fall in the 1986 cost of living - the steep decline in both oil prices and the value of the dollar, the institute said in a report. The institute said inflation will see a rising trend in the course of 1987, but will average only 0.5 pct for the year as a whole because year on year rates will remain negative in the first part of 1987. Provisional inflation figures for February released last week showed the cost of living last month was 0.5 pct lower than in February 1986. In January prices had fallen 0.8 pct against the same month a year earlier. The HWWA said its forecast assumed the dollar would remain around 1.80 marks and oil prices would range between 15 and 17 dlrs per barrel.
