The Obama administration is increasingly confident the U.S. economy is accelerating, and the increased growth will help government finances, Treasury Secretary Jacob Lew said Thursday. "What we're seeing in all the economic indicators is that the trajectory of growth is rising," Lew told CNBC financial television from Davos, Switzerland. The Treasury chief's views echoed the broad sentiment among private-sector economists that the U.S. economy is set for its fastest year of growth since 2005. An improving economy means the government receives more tax revenue. "Certainly, projections suggest that," Lew said. Economists expect U.S. gross domestic product (GDP) to grow by 2.9 percent this year, which would be the fastest in nine years.
