摘要翻译：
由于潜在的动态项目范围，通常需要处理消费者价格指数中的质量变化和新商品。传统上，公理化测试是为一个固定的宇宙定义的。我们提出了五个为动态项目域显式制定的测试，并从商品成本指数和生活成本指数的角度来激励它们。没有一个索引能同时满足所有的测试，这些测试目前可用于使用包括整个项目域的扫描仪数据。测试集为索引在动态项目域中是否完全合适提供了严格的诊断，并指出了可能的补救措施的方向。因此，我们概述了一个可以满足所有测试的大型索引族。

英文摘要：
There is generally a need to deal with quality change and new goods in the consumer price index due to the underlying dynamic item universe. Traditionally axiomatic tests are defined for a fixed universe. We propose five tests explicitly formulated for a dynamic item universe, and motivate them both from the perspectives of a cost-of-goods index and a cost-of-living index. None of the indices satisfies all the tests at the same time, which are currently available for making use of scanner data that comprises the whole item universe. The set of tests provides a rigorous diagnostic for whether an index is completely appropriate in a dynamic item universe, as well as pointing towards the directions of possible remedies. We thus outline a large index family that potentially can satisfy all the tests.
