Fed's Kashkari - Fed should be patient, allow inflation to build

Fed's Kashakri's comments are crossing the wires via Reuters-

• Fed should be patient, let inflation build. 
• Don't know if the US is at full employment. 
• We are not sure about the neutral rate or output gap either. 
• Best hope is that tax cuts lead to greater investment and productivity. 
• Is very focused on wage growth, labor market slack and inflation. 
• 2-percent inflation target would give Fed more flexibility in fighting future downturns. 
• Fed will respond if inflation starts to show itself. 
• We are seeing some signs of inflation building, but takes more than one month's data. 
• Wants to see definitive signs of inflation rising to 2 percent before supporting more rate hikes.
