“Another way to keep an eye on inflation is with MIT’s Billion Prices Project (previous post) which tracks prices in real-time by grabbing them from websites. By checking on 50,000+ different prices daily covering everything from prescription drugs to clothing to real estate, this alternative inflation measurement has the potential to keep governments “honest” with their numbers. Over the past five years, the two indexes have actually tracked relatively closely. Just recently, the two are diverging a bit; BPP is showing a little over 2% inflation as opposed to 1.5% from CPI.”
