It's being republished as a bonus for TheStreet.com readers.As recent debate on the pages of this Web site has shown, there is a divergence of inflation views. There's plenty of misinformation and spin out there, too. I believe the economy is experiencing robust inflation, and has been for some time. While energy certainly is a part of that -- crude oil has run from $25 to as high as $70 -- inflation is not just confined to energy.
What Is Inflation?Inflation is the rate of increase in general prices of all goods and services. It also can be described as a decrease in the purchasing power of money.

By taking out the more volatile elements, economists ostensibly avoid having a single outlying month disrupt an orderly data series. More numerically literate observers might think a simple moving average would do the same thing. It would reveal when prices are rising, while smoothing the impact of one-time price spikes. Yet this is not how most economists report CPI. One has to wonder why they have been reporting inflation data excluding energy 48 months into a robust move upward in oil prices. That hardly looks like removing a one-time "outlier." The CPI ex energy measure is misleading, as it makes inflation appear far more benign than it really is. But don't think it's just energy; lots of other items have also risen in price. The CRB Index, for example, has been in a strong uptrend since October 2001.
