Questo documento e' in effetti di qualche anno fa.
Il fatto e' che non se ne piu' parlato quindi non saprei se le raccomandazioni proposte siano state implementate o no.
Motor trade industry review
(Statistics/Gov/UK)
This industry review has made changes to the data sources and methods currently used by IoS and GDP(O) (they both use the same data sources and methodology) to measure the motor trade indutry. The main thrust of the changes is to replace volume indicators with monthly deflated turnover data
The previous methodology used registration data as a proxy for sales
• For franchised dealers more emphasis has been placed on the bonuses
paid by manufacturers on achieving sales targets, rather than on discounts
• For this reason, dealers have been pre-registering new vehicles in order to meet short- term sales target.
• These cars are assumed under the previous method to be sales when the cars are still on the garage forecourt
We have recommended the use of SMMT/DVLA weights that
show car registrations by type of customer.
This is a conceptually better methodology in accordance with Eurostat guidance.
Benefits of new methodology
• Data measures sales rather than registrations (not all cars registered are actually sales due to pre-registration) .
Una cosa e certa fino a qualche anno fa gonfiano i dati.
