Detailed Average Prices Project Experience of Statistics Belgium

This workshop delves into the detailed process of calculating indicative price levels using CPI/HICP data in Belgium. It covers the national average prices, methodology changes, and future challenges faced in spatial and temporal price comparison. Major updates include automating price calculations, optimizing metadata, and expanding the product sample for representativity. Explore the synergy between HICP/CPI and PPP and potential use of scanner data for FMCG analysis. Connect with experts at the workshop to enhance your understanding of consumer price statistics.

  3. Introduction Aim project: to use the available monthly data of the CPI/HICP to calculate indicative price levels on a regular basis for welldefined products and services Overall goal: temporal and spatial price comparison http://economie.fgov.be

  4. Provision of prices June 2010 National average prices: Procedure existed before start of the project since Belgium has already a tradition in publishing average monthly prices of all products in the CPI/HICP.

  5. Ex-post approach: “selecting those CPI/HICP price observations that match exactly the given product definitions”

  6. Provision of pricesJune 2011/2012 Major changes comparedto 2010: • Increasing sample of productsby 51 products (ex-ante approach) - Further automatisation of calculation • Info brand products: predefined text free text (data cleaning) - Optimizing metadata: especially for electronic devices

  7. Electronic devices: separate price collection

  8. Well known brand / brandless: • Differentapproach for different types of products - FMCG - clothing - electronicdevices • Input of PPP-colleagueswasvery important

  9. Future Challenges: • Further expand sample of products: representativity Belgian market • Sample structure: analysis of scanner data of consumer panel research bought from a market research company • Methodology changes HICP/CPI: possible use of scannerdata in the future for FMCG? • Synergie between HICP/CPI and PPP: limited; extra cost DAP
