The overall price level contains prices of everything purchased or purchasable (Fischer, 1911). The consumer price index only covers a small subset of all prices in the economy and since these prices are among the stickiest in the economy, this index may not fully capture the true rate of monetary inflation in the short run. Merging all price indices into one overall index has been rejected, not least for practical reasons. Issing (2003), though, argues that money growth can be interpreted as a proxy for the overall inflation rate; hence it is unnecessary to create a price index if the money growth rate can be used instead.
