Plosser, Charles

I am not particularly concerned about the possibility of persistent deflation. When oil and commodity prices stabilize, the negative rates of inflation we have seen in the CPI are likely to disappear. Moreover, I am confident that the FOMC is committed to maintaining price stability. Nonetheless, we must act to ensure that expectations of deflation do not take root, just as we must act to ensure that expectations of higher inflation do not emerge. The failure to maintain well-anchored inflation expectations can wreak havoc with the real economy, foster unnecessary volatility, and make it more difficult for the Fed to deliver on its dual mandate to keep the economy growing with maximum employment and price stability.

I and others have long proposed establishing an explicit inflation target as one way to signal the FOMC's commitment to price stability and help anchor expectations. Such a commitment not only helps prevent inflation expectations from rising to undesirable levels, but it can also help prevent expectations from falling to undesirable levels.
