Where’d Those Numbers Come From? Data for the Pricing Posts

Fig 1.
Fig 1.

Premium Pricing for major technological innovations raised average prices of hearing aids by about $1000 from 1994 to 2011, as shown in a previous post and reproduced above.

The Data


Fig 1 was derived from the numbers contained in Table 1, footnoted to explain origins, derivations, and assumptions.  Nominal average Price (left column of Table 1) from 1980-1999 was compiled and provided by Karl Strom, Editor of Hearing Review.  Real average Price (2nd column, Table 1) was calculated by multiplying column 1 figures by a simple purchasing power calculator.  Real Price adjusted for technological shocks (column 3) adds estimated price adjustments of successive generations of technologies to the values of column 2.

Readers are encouraged to contribute better numbers, more numbers, and corrections.

  1. I think it’s inevitable that the upward trend line will start to normalize and get flatter. The current market forces in play are going to begin dropping that trend line closer to CPI…albeit not nearly as much as the average consumer would like it to be…
