The Norwegian economy is a prosperous bastion of welfare capitalism, featuring a combination of free market activity and government intervention. The government controls key areas, such as the vital petroleum sector (through large-scale state enterprises). The country is richly endowed with natural resources - petroleum, hydropower, fish, forests, and minerals - and is highly dependent on its oil production and international oil prices, with oil and gas accounting for one-third of exports. Only Saudi Arabia and Russia export more oil than Norway. Norway opted to stay out of the EU during a referendum in November 1994. The government has moved ahead with privatization. With arguably the highest quality of life worldwide, Norwegians still worry about that time in the next two decades when the oil and gas begin to run out. Accordingly, Norway has been saving its oil-boosted budget surpluses in a Government Petroleum Fund, which is invested abroad and now is valued at more than $43 billion. GDP growth was a lackluster 1% in 2002 and 0.5% in 2003 against the background of a faltering European economy.
