Price index[edit]

Please note that, contrary to your edit, a price index is not an inflation rate. An inflation rate is an over-all change in prices divided by the corresponding elapse of time. A price index attempts to measure prices at one time reltive to those at another, corresponding only to the numerator of an inflation rate calculation. Further, the two times might be named in a manner that doesn't allow us to calculate the inflation rate. If we have the index of the price level at the start of King Bolanga's rule relative to that at the end of King Watanda's rule, we (setting aside the case where the index is 1) we cannot calculate the inflation rate unless we know how much time elapsed between these two reigns. —SlamDiego_←T 08:56, 11 September 2009 (UTC)[reply]
