The US has lost its place as the world's most competitive economy,according to a survey released on Tuesday,falling behind Switzerland mainly because of the financial crisis and accumulated fiscal deficits. The survey,which combines opinions of over 13,000 business executives with economic statistics and government regulations,put Switzerland in first place and dropped the US to second place. From 2006 to 2008,the US was No 1 in the survey conducted by the Geneva-based World Economic Forum. Before that Finland held the top spot. "Given that the financial crisis originated in large part in the US,it is hardly surprising that there has been a weakening of the assessment of its financial market sophistication," the survey said. "The country's greatest weakness continues to be related to its macroeconomic stability." The US' high budget deficit,a very low savings rate and a public debt that has been rising over the past years have weakened macroeconomic stability,said Margareta Drzeniek Hanouz,a senior economist who worked on the survey. Pollsters asked business leaders to assess how growth-oriented 133 countries were,using the following criteria: good government; transport and telecommunications infrastructure; openness to innovation; intellectual property protection,and availability of talent. They also took into account economic output,number of computers and the procedures required to start up a business.
