单词	volume index
释义	volume index Economics An index of the real level of production or consumption, in the whole economy or some part of it. A volume index is a weighted average of the production or consumption of some suitably chosen bundle of goods. The weights are the prices in some period. Where 0 is the base period and t the current period, p_it the price and q_it the quantity of good i produced or consumed in period t, a base-weighted, or Laspeyres, volume index is defined by $q_{B} = \sum_{i = 1}^{n} p_{i 0} q_{i t} / \sum_{i = 1}^{n} p_{i 0} q_{i 0}$ and a current-weighted, or Paasche, volume index is defined by $q_{C} = \sum_{i = 1}^{n} p_{i t} q_{i t} / \sum_{i = 1}^{n} p_{i t} q_{i 0} .$
