IMF economist Pierre-Olivier Gourinchas gave his assessment as the organization projected that global economic growth would slow to 3 percent this year and next year, down from 3.5 percent last year. IMF research director Pierre-Olivier Gourinchas speaks at a news conference during the World Bank/IMF Spring Meetings at the IMF headquarters in Washington on April 11. The IMF lifted its outlook for US growth this year to 1.8 percent, up 0.2 percentage points from April, but expects it to slip to 1 percent next year.
