DUTCH PLANNING AGENCY FORECASTS LOWER GROWTH Dutch economic growth is slowing as a firming guilder cuts competitiveness abroad and industries reduce the pace of investment, the Dutch official planning agency CPB said. The Centraal Planbureau, publishing its 1987 economic outlook, said Dutch Net National Income (NNI) was expected to grow by one pct this year, down from two pct growth recorded in 1986 and 2.5 pct in 1985 and 1984. Dutch Gross National Product is expected to rise to 432.20 billion guilders in 1987 in constant prices, a two pct increase from last year's 423.95 billion. The CPB, forecasting an 8.5 pct increase in the value of the guilder on a trade-weighted basis compared with 10.0 pct last year, said the dollar was expected to trade at an average of 2.0 guilders in 1987 compared with 2.45 guilders in 1986. "The higher guilder is causing a substantial fall in unit labour costs abroad, when measured in guilder terms, while these are rising slightly in the Netherlands," the CPB said. More of economic growth now depended on domestic consumption, the CPB said, but noting that higher margins set by domestic producers and importers mitigated the effect on purchasing power of lower import costs and deflation. Consumer prices were set to fall by 1.5 pct this year, the CPB said. Inflation was zero last year. Gross investment in industry was expected to grow by five pct this year, a slowdown compared with 11.5 pct growth last year, the CPB said. Exchange rate and oil price fluctuations will continue to condition the Dutch economy in the future as it has in recent years, the CPB said, noting a continued depressing impact of these factors on Dutch competitiveness. In addition, it noted a slight rise in taxation and social security costs to employers. The CPB, forecasting a rise in the budget deficit to 7.2 pct of Net National Income in 1987 from 6.3 pct last year, urged the government to cut expenditure further to bring down the deficit and reduce tax and social security payments in future. Dutch government revenue is being depressed further by falling income from natural gas sales in 1987, the CPB said. It said unemployment was expected to fall to 675,000 this year from 710,000 last year. While the two pct GDP growth forecast set by the CPB is within its latest forecast, issued last month, of 1.5 to two pct growth, the figure is well above recent market estimates. Dutch merchant bank Pierson, Heldring en Pierson said in its February economic outlook that GDP growth at constant prices was expected to be 1.1 pct this year and market analysts had expected the CPB's final forecast to be below its own latest estimate. "It is too early to comment because I haven't seen the whole document yet, but it would seem we are more pessimistic in some of our estimates," a Pierson economist said. The CPB forecast 2.5 pct export growth in volume terms in 1987, after four pct growth last year. Excluding energy exports, the 1987 figure would be two pct, it said. Imports were set to rise by 4.5 pct this year compared with four pct in 1986 in volume terms, the CPB said. The balance of payments would see a sharp decline in the surplus, to six billion guilders in 1987 compared with 12.1 billion last year, the CPB forecast.
