Scanner Data in the Consumer Price Index: How to expand and improve their use

消费物价指数(CPI)被用于各种政策背景，如制定利率和确定福利支付水平，以及私营行业用来确定工资。CPI是价格变动的综合衡量标准。它通常是使用调查数据构建的，调查数据是所有购买的商品的小样本。使用扫描的产品条形码的电子销售记录提供了大量的价格和数量信息，这些信息可能被用来构建改进的CPI，从而改进政策。该项目包括澳大利亚统计局和中央统计局(荷兰)的协作。

The Consumer Price Index (CPI) is used in a variety of policy contexts, such as setting interest rates and determining the level of welfare payments, as well as by private industry for determining wages. The CPI is aggregate measure of price changes. It is typically constructed using survey data, which is a small sample of all the goods purchased. Electronic recording of sales, using scanned product bar codes, provides a huge amount of price and quantity information that potentially can be used to construct an improved CPI, and hence improved policies. The project includes the collaboration of the Australian Bureau of Statistics and the Central Bureau of Statistics (The Netherlands).
