In the construction industry, the labour market is tight and enterprises are making use of foreign labour to some extent. The supply of skilled labour is, however, a constraint on growth potential. Signals from service industries also indicate that the supply of labour is becoming more limited. The general level of investment in this region is relatively stable. Investment activity in the public sector appears to be somewhat lower in 2005 than in 2004. In manufacturing and services, there are signs of increased investment activity. Tender prices are rising slightly in the building and construction industry as a result of increased costs and a higher level of activity throughout the country. Prices have risen slightly in manufacturing and service industries. In retail trade, prices have changed little or remained unchanged. Profitability is improving due to increased activity, but there are no major changes for small and medium-sized enterprises. In the approved budget for 2005, the structural, non-oil deficit increases compared with 2004. It therefore appears that fiscal policy will provide some stimulus to growth this year. In the National Budget for 2005, underlying spending growth over the central government budget was estimated at 5.2 per cent, which is somewhat lower than the previous year and somewhat lower than estimated nominal growth in mainland GDP. As from 2006, it is assumed that nominal growth in central government expenditure will be approximately the same as nominal growth in central government revenues and that the real tax level will remain unchanged.
However, we assume that households will choose to spread consumption over time, so that the saving ratio will continue to fall in spite of an increase in interest rates. Housing construction activity is still high. In January and February, housing starts were 17.5 per cent higher than in the same period last year. Growth in housing investment is expected to ease through 2005. However, the projection for housing starts is also very high for 2005. Such a high level of housing starts over several years probably means that more dwellings will be constructed than implied by underlying demand. As a result, housing investment is expected to decline after a period. Higher interest rates and weaker developments in the Norwegian economy may also lead to a fall in residential construction after a period. The rise in house prices has moderated, and prices in March were 8.2 per cent higher than in the same month last year. The upturn in mainland fixed investment is broadly based. Stronger profitability, higher capacity utilisation and solid export growth will contribute to continued investment growth in goods-producing industries. Demand for services is expected to continue to grow for a period ahead with an attendant increase in investment in service sectors. When growth in the economy gradually slows, investment growth will probably slacken. Mainland exports of goods and services will also benefit from solid global growth this year. Later in the period, a continued loss of market shares as a result of high cost levels will dampen export growth.
