There's been a lot of talk about the effectiveness of QE policies and whether they've been worthwhile. I think the ultimate answer can be summed up in two words: why not? The main concern about QE is the potential for runaway inflation, but that's simply not happening, even after five years of increasing the money supply. The fact is, Americans (consumers and businesses) are saving more than spending. While that's the case, inflation will simply not occur. Plus, if inflation does start to show up in the data, it won't happen overnight. Thus, the Fed will have plenty of time to react. Don't forget, the Fed has a strong history of being able to combat inflation. As long as fiscal policy is off the table, there's no reason for the Fed not to try any method possible to spark economic growth.
