The U.S. Federal Reserve's decision to raise its benchmark rate on Dec. 16, for the first time in a decade, was unanimous, but how quickly it will raise rates again is an open question
— and one that will be vigorously debated as new, more hawkish voting members of the Fed's rate-setting Federal Open Market Committee take their seats in 2016, _The Wall Street Journal_
predicts. Disagreement makes sense, because trying to steer a massive market economy like America's through interest-rate adjustments and monetary supply is an arduous balancing act.
If the Federal Reserve's rate deliberations seem sort of abstruse, or make your eyes glaze over, _The New York Times_ created a Rube Goldberg machine to explain how the Fed uses a rate
