Definition: Fisher price index


The Fisher price index is an index formula used in price statistics for measuring the price development of goods and services, on the basis of the baskets from both the base and the current period. It is defined as the geometric average of the Laspeyres price index (which only uses the base period basket) and the Paasche price index (which only uses the current period basket). For this reason, the Fisher price index (named after American economist Irving Fisher) is also known as the "ideal" price index.
