Chained Dollars

 (Economics Term)

Dollar values calculated by taking the current dollar level of a series in the base period (or period from which the weights for a measurement series are derived) and multiplying it by the change in the chain quantity index number for the series (calculated using chained weights) since the base period. Chained-dollar estimates correctly show growth rates for a series, but the summed components do not equal the aggregate in periods other than the period from which the weights for a measurement series are derived. (See also Chain Price Indexes; Real Dollar.)
