A military power during the 17th century, Sweden has not participated in any war in almost two centuries. An armed neutrality was preserved in both World Wars. Sweden's long-successful economic formula of a capitalist system interlarded with substantial welfare elements has recently been undermined by high unemployment, rising maintenance costs, and a declining position in world markets. Indecision over the country's role in the political and economic integration of Europe caused Sweden not to join the EU until 1995, and to forgo the introduction of the euro in 1999.
Aided by peace and neutrality for the whole twentieth 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. In recent years, however, this extraordinarily favorable picture has been somewhat clouded by budgetary difficulties, high unemployment, and a gradual loss of competitiveness in international markets. Sweden has harmonized its economic policies with those of the EU, which it joined at the start of 1995. GDP growth is forecast for 4% in 2001.
