This Times article on the economy's lower-than-expected growth raises the specter of stagflation. Since the S word has been popping up in a variety of places lately, I think it might be worth a quick definition, as I sure as hell didn't know what it meant a year ago.
Stagflation occurs when the economy has high inflation combined with economic stagnation, unemployment, or recession. So the basic force at work is that prices, through inflation, are rising, but buying power isn't, either because folks don't have jobs, we're in a recession, or the economy's standing still.
