My two favorite pieces of Boskin intellectual fraud are substitution and hedonic adjustments. Hedonic adjustments are addressing the improvement in quality as a form of deflation. For example, the price of a new car in the U.S. had risen from $6,847 in 1979 to $27,940 in 2004. Using hedonic adjustments, the government calculated the price of a new car had risen from $6,847 in 1979 to $11,708 in 2004. These adjustments wildly distort not only CPI data but GDP as well. Bill Fleckenstein calculated that the hedonic adjustments of faster computer chips and dropping costs massively jacked up the productivity data and GDP data from 1995-2002.
Substitution is a nonsensical approach that adjusts inflation for consumer behavior. When steak prices rise, consumers “substitute” cheaper proteins such as hamburger or chicken. Thus, Boskin states, the consumer is spending no more than they previously were, and is not suffering inflation. The reality is that consumers have been priced out of steak due to price increases. Oh, and somehow, the decrease in quality does not get hedonically adjusted when it raises inflation.
