In the 1990s, the German economy began to experience structural problems caused by the shock of changes in the internal and external environments, and after 2000 its per capita GDP started slipping behind that of other EU members. In 2003, its economy not only slumped into recession, but it also experienced the highest levels of fiscal deficit and unemployment since 1991. Since the mid-1990s, the federal government has responded with such measures as cutting income tax, restructuring taxation, deregulating the labor market, encouraging mini (part-time) job creation, reviewing the social security system, and reducing social benefits spending. The so-called "sick man of Europe" finally entered a broad-based economic recovery in 2006, after hosting the FIFA World Cup, with investment rising, unemployment and the fiscal deficit consistently improving, and business and consumer confidence returning.
