Philadelphia Fed President Charles Plosser on Tuesday continued to make the case for ending the current asset purchase program sooner to reflect the improvement in the economic outlook and to lessen some of the communications problems the Federal Open Market Committee will face with its forward guidance. Plosser said the unseasonably cold, winter weather impacted the January jobs data and added it may take "another couple of months" to have a better read on the underlying pace of the economy. Plosser, a voting FOMC member, says the economy will grow around 3% this year.
