Using the Retail Distribution of Sellers to Impute Expenditure Shares
提出在没有基础数量数据时,可用卖家零售分布推算支出份额,从而减少价格变动频率、年通胀率和跨国价格比较中的偏差。
Many price indices must be constructed without quantity data at the elementary level. The paper shows that for some consumer goods in the United States and other countries, one can approximate expenditure shares using weights derived from the retail distribution of sellers. These weights are based on the share of outlets selling an item, or the share of outlets adjusted by the total number of items sold in each. Relative to using no weights, the paper finds that using such imputed weights substantially reduces bias in the frequency of price changes, in annual inflation, and in price comparisons across countries.
