The head of the International Monetary Fund said Saturday that some countries that use the euro have the flexibility to boost growth to help shore up the ailing eurozone economy. Speaking at the World Economic Forum in Davos, Christine Lagarde said the 17 nations that use the euro should not undertake dramatic spending cuts to reduce debts at the same pace or to the same degree. "Some countries have to go full-speed ahead to do this fiscal consolidation, but other countries have space and room," Lagarde was quoted as saying by the Associated Press. Though conceding that there weren't many of them, Lagarde said it was important that those that have the headroom should explore how they can boost growth. In addition, Lagarde said members of the eurozone should continue the drive to tie their economies closer together over the months and years ahead.
