Fed's Kashkari: Fed's policy tightening has led to low inflation

Key highlights (via LiveSquawk) from the essay titled "My Take on Inflation" by Minneapolis Fed President Neel Kashkari:

• Fed's policy tightening has led to low inflation
• Fed should proceed with caution before tightening policy further
• Prefers Fed not raise rates until core PCE inflation reaches 2%
• Job growth, wage growth, inflation weaker than would have been had Fed not raised rates
• Labor market slack, falling inflation expectations are causing persistently low inflation
• Allowing inflation expectations to slip give Fed less room to respond to future economic downturn
