Sept 27 (Reuters) - Chicago Federal Reserve Bank President Charles Evans on Monday said he expects inflation to rise to 2.4% by 2024 but interest rates to be only on a “gentle incline” upward, a view that contrasts with that of some other policymakers who believe a faster pace of rate hikes will be needed. “We are trying to solidify strong, firm inflation expectations that allow for 2% over time as an average,” Evans told reporters on the sidelines of the National Association for Business Economics. In his view, he said, “the brief period of higher inflation... is helpful for reinforcing inflation expectations.” (Reporting by Ann Saphir editing by Chizu Nomiyama)
