For example, the classic tax exempt 1929 Holding Company was outlawed 31 December 2010, as it was deemed an illegal state aid by the European Commission.
A key event in the economic history of Luxembourg was the 1876 introduction of English metallurgy. The refining process led to the development of the steel industry in Luxembourg and founding of the Arbed company in 1911.
The iron and steel industry, located along the Frenchborder, is an important sector of the economy. Steel accounts for 29% of all exports (excluding services), 1.8% of GDP, 22% of industrial employment, and 3.9% of the work force.
The restructuring of the industry and increasing government ownership inArbed (31%) began as early as 1974. As a result of timely modernization of facilities, cutbacks in production and employment, government assumption of portions of Arbed's debt, and recent cyclical recovery of the international demand for steel, the company is again profitable. Its productivity is among the highest in the world. U.S. markets account for about 6% of Arbed's output. The company specializes in production of large architectural steel beams and specialized value-added products. There has been, however, a relative decline in the steel sector, offset by Luxembourg's emergence as a financial center. In 2001, through the merger with Aceralia and Usinor, Arbed became Arcelor. Arcelor was taken over in 2006 by Mittal Steel to form Arcelor-Mittal, the largest steel producer in the world.
Government policies promote the development of Luxembourg as an audiovisual and communications center.Radio-Television-Luxembourg is Europe's premier private radio and television broadcaster. The government-backed Luxembourg satellite company "Société européenne des satellites" (SES) was created in 1986 to install and operate a satellite telecommunications system for transmission of television programs throughout Europe. The first SES Astra satellite, the 16-channel RCA 4000 Astra 1A, was launched by the Ariane Rocket in December 1988. SES presently constitutes the world largest satellite services company in terms of revenue.
Tourism is an important component of the national economy, representing about 8.3% of GDP in 2009 and employing some 25,000 people or 11.7% of the working population. Despite the current crisis, the Grand Duchy still welcomes over 900,000 visitors a year who spend an average of 2.5 nights in hotels, hostels or on camping sites. Business travel is flourishing representing 44% of overnight stays in the country and 60% in the capital, up 11% and 25% between 2009 and 2010.
Luxembourg's small but productive agricultural sector is highly subsidized, mainly by the EU and the government. It employs about 1%-3% of the work force. Most farmers are engaged in dairy and meat production. Vineyards in the Moselle Valley annually produce about 15 million litres of dry white wine, most of which is consumed within Luxembourg and also in Germany, France, and Belgium on a lesser scale.
