Myth #5: The Producer Price Indexes for retail trade measure changes in prices paid to retailers (similar to the Consumer Price Index).
Fact Check: The Producer Price Indexes for retail trade measure changes in gross _____ received by retailers.

Myth #6: Producer Price Indexes exclude transportation costs.
Correct!
The Producer Price Index does capture changes in transportation costs. The methodology for measuring these costs depends on how they are incurred; specifically, it depends on whether the transportation is provided by the producer of the goods or by a third party.

The Producer Price Index does capture changes in transportations costs. The methodology for measuring these costs depends on how they are incurred; specifically, it depends on whether the transportation is provided by the producer of the goods or by a third party.
Myth #7: Changes in product quality affect Producer Price Indexes.
Correct!
A primary objective of the Producer Price Index is to measure changes in constant-quality prices. Measurement of constant-quality prices ensures that the Producer Price Index measures what is commonly referred to as “pure” price change. Pure price change can be defined as price change based on market factors, not change in item quality such as, physical changes to the item or changes in the way the item is sold.
Sorry, that's not quite right.
Producer Price Indexes measure “pure” price changes and are adjusted for quality changes so that they are not reflected in the price change used in index calculation.

Myth #8: Producer Price Index methodology for measuring price movements is always similar for services and goods.
Fact Check: As the Producer Price Index began development of services indexes for more complex industries, obtaining pricing information for these industries required _____ price concepts as those used for goods producers.
Correct!
In the early years of the services expansion in the Producer Price Index, the industries being introduced generally were methodologically straightforward, with significant similarities to manufacturing industries. Therefore, this expansion typically utilized price collection and tracking approaches that were similar to those used for collecting and tracking prices from goods producers. Over time, the Producer Price Index began developing indexes for more complex service industries, such as those in the finance and insurance sector, and obtaining information for these industries required new and innovative price concepts.

Thank you for taking the Debunking 8 Common Misconceptions about the Producer Price Index Quiz!
Most of the common misconceptions about the Producer Price Index result from its broad scope. The Producer Price Index is not a single index but a set of approximately 10,000 indexes that cover goods, services, and construction, reflecting sales to all buyer types with the objective of measuring pure price change. Producer Price Index methodologies are driven by the measurement objective of the program as a producer-based, voluntary, respondent survey collecting prices from over 500 individual industries. For many of these industries, especially service-providing industries, methods are not straightforward. Issues such as quality adjustment, and differences between the Producer Price Index and the Consumer Price Index, also contribute to misconceptions about the Producer Price Index.
