The problem with financial market indicators is that asset prices respond to any number of risks, not just inflation. In a world that is always confronting and evaluating risks, disentangling the inflation risk from all the other risks is a very imperfect science. Nevertheless, financial market indicators are proving to be a useful yardstick for monitoring inflation expectations...
You might think that a better way to gauge inflation expectations would be to simply ask people their views on inflation. In fact, there is a survey that does just that. Once a month, the University of Michigan interviews about 500 households around the nation, asking people how much they think prices will rise in the next 12 months and over the next 5 to 10 years. Here, too, there are some problems with interpreting the raw data. For one thing, households' beliefs about future inflation are typically much higher than the actual inflation rate.
Also, investigations into the survey data have revealed some fascinating patterns. For example, people are likely to report their inflation predictions in terms of whole numbers, and particular whole numbers at that. It turns out that people are far more likely to report that they expect 0, 3, or 5 percent inflation than 1, 2, or 4 percent.
