Chained dollars is a method of adjusting real dollar amounts for inflation over time, so as to allow comparison of figures from different years.〔Mark McCracken, (Definition of Chained dollars ) TeachMeFinance.com. Accessed 2009.05.11.〕 The U.S. Department of Commerce introduced the chained-dollar measure in 1996. Chained dollars generally reflect dollar figures computed with 2009 as the base year. Terms ''Constant Dollars:'' weighted by a constant/unchanging basket/list of goods and services. ''Chained Dollars:'' weighted by a basket/list that changes yearly to more accurately reflect actual spending. The basket is an average of the basket for successive pairs of years; example of paired years are 2010-2011, 2011-2012, etc. The technique is so named because the second number in a pair of successive years becomes the first in the next pair. The result is a continuous "chain" of weights and averages.〔U.S. Department of Energy, (Chained Dollars ), citing EIA, ''Annual Energy Review 1999''.〕 The advantage of using the chained-dollar measure is that it is more closely related to any given period covered and is subject to less distortion over time.〔Mark McCracken, ''op. cit.''〕 ==See also== * Inflation adjustment * Constant dollars 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「chained dollars」の詳細全文を読む スポンサード リンク
