Luxembourg’s stable and high-income market economy features moderate growth, low inflation, and a high level of innovation. Luxembourg is the second richest country in the world, with a per capita GDP on a purchasing-power parity (PPP) basis of $80,119. Luxembourg is ranked 13th in the Heritage Foundation’s Index of Economic Freedom, 24th in the United Nations Human Development Index, and 4th in the Economist Intelligence Unit’s quality of life index. The industrial sector, which was dominated by steel, has since diversified to include chemicals, rubber, and other products. Growth in the financial sector has more than compensated for the decline in steel production. Services, especially banking and finance, account for the majority of economic output. Luxembourg is the world’s second largest investment fund centre (after the United States), the most important private banking centre in the Euro zone and Europe’s leading centre for reinsurance companies. Moreover, the Luxembourg government has aimed to attract internet start-ups, with Skype and Amazon being two of the many internet companies that have shifted their regional headquarters to Luxembourg.
