Some people might think it’s odd to focus completely on how prices are calculated, but things like the CPI and PCE-deflator have become part of the fundamental fabric of finance and economics. Economic indices are considered a given, when in reality they contain embedded assumptions that flow into every aspect of economic thought; Economists always consider “real” prices, i.e. nominal prices adjusted by some price index. If the price index is wrong, then the entire thought structure built upon it is at best misguided, at worst completely biased.
My background is in high frequency prop trading, making markets in interest rate derivatives. I get angry when markets are manipulated, and this blog is an outgrowth of that unpleasant sensation.
