Aided by peace and neutrality for the whole 20th century, Sweden has achieved an enviable standard of living under a mixed system of high-tech capitalism and extensive welfare benefits. It has a modern distribution system, excellent internal and external communications, and a skilled labor force. Timber, hydropower, and iron ore constitute the resource base of an economy heavily oriented toward foreign trade. Privately owned firms account for about 90% of industrial output, of which the engineering sector accounts for 50% of output and exports. Agriculture accounts for only 2% of GDP and 2% of the jobs. The government's commitment to fiscal discipline resulted in a substantial budgetary surplus in 2001, which was cut by more than half in 2002, due to the global economic slowdown, declining revenue, and increased spending. The Swedish central bank (the Riksbank) is focusing on price stability with its inflation target of 2%. Growth remained sluggish in 2003. On September 14, 2003, Swedish voters turned down entry into the euro system, concerned about the impact on democracy and sovereignty.
