SPPI Methodology
Surveyed products
Product list defined with the respondents (8) Specific products or transactions agreed with each individual observation unit (5) Standard statistical product list (e.g. CPA) (4) Self developed product list (2)
Data collection
Postal and phone surveys Electronic questionnaires via mail Electronically reporting system

Quality Adjustment
VBG agenda items in 2010 and 2011
Implicit methods preferred
Overlap method
Comparable replacement
www.statistik.at slide 15 | April 18, 2023
Main Conclusions
Turnover part is well developed
A sample of few enterprises results in a market coverage above 70% in regard to turnover coverage
Flexible economy class booking categories should also be considered for SPPIs
Monthly/Quarterly average prices presumably more accurate in regard to the characteristics of yield management systems
www.statistik.at slide 16 | April 18, 2023
Main Conclusions cont.
CPI data for air transport for b2b SPPIs or the consumer part of b2all SPPIs (two other methods lead)
IATAs Cargo Account Settlement System (CASS) for freight air transport
Electronically reporting systems
To quality adjust in the case that the production function has changed
