The Global Competitiveness Report (GCR) is a yearly report published by the World Economic Forum which is a Swiss non-profit foundation, based in Cologny, Geneva. The first report was released in 1979. The 2011–2012 report covers 142 major and emerging economies. Switzerland leads the ranking as the most competitive economy in the world, as the United States, which ranked first for several years, fell to fifth place due to the consequences of the financial crisis of 2007–2010 and its macroeconomic instability.
