Paasche
Paasche is a surname of German origin and can refer to people who bear the name, as well as to terms and products named in association with it. In economics, the Paasche price index is a price index named after the German economist Hermann Paasche (circa 1853–1935). It measures the change in the cost of purchasing the current period’s basket of goods and services, using current-period quantities as weights. The index is calculated as the ratio of the total cost of the current-period quantities at current prices to the total cost of those same quantities at base-period prices. This approach contrasts with the Laspeyres index, which uses base-period quantities as weights. Paasche indices are used in inflation measurement and economic analysis, often alongside other price indices.
In the field of consumer and professional equipment, Paasche is also a brand of airbrush and spray
