Definition: Product error
Purchasing power parities
A product error occurs when price collectors price products that do not match the product specification and neglect to report having done so. This can be because they are not aware of the mismatch, such as when the product specification is too loose, or because they price a substitute product as required by the pricing guidelines but do not mention this on the price reporting form.
