  1. Local and Regional Procurement Learning Alliance 6. Market Data ASSESSING SECONDARY DATA

  2. Using secondary data: • Conserves time & resources: utilize secondary data whenever possible; collect primary data to fill gaps • Requires identification of existing sources: price data is often collected by governments, international organizations, national agricultural research services (NARS) • Secondary data may be available for wholesale and/or retail prices; we need both • After requesting price data, always clarify collection method • Requires that primary data be collected using same procedures as secondary data: this approach ensure comparability and combinability

  3. Price data collected by a governmental or other agency • Check agricultural ministries, trade ministries, national statistical offices for agricultural price data • Look online, in local news media, historical publications and archives • Search first, then arrange a visit with data collection agency

  4. Examples of online sources • Start here: • List of country-specific statistical agencieshttp://www.ssb.no/en/links/ • Government databases: • Bangladesh’s Department of Agricultural Marketing: http://www.dam.gov.bd/jsp/advancedSearchReport.jsp • Benin (French only): http://www.insae-bj.org/ • NARS databases: • Check with CGIAR centers, WFP country offices, FAO country offices • Dataaggregators: • Famine Early Warning System Network (FEWS NET): http://www.fews.net/Pages/markettrade.aspx?loc=3&l=en

  5. Understanding the methods used by governmental or other agencies to collect data • Examine methodology, surveys (if available), prior to meeting with agency official • Ask officials how, where and when data are collected with a series of targeted questions • Only use data collected monthly or more often • Understanding previously used methods is critical for process replication and data comparability

  6. Example questions to ask agency official • From what markets are these prices collected? • Are the prices in the dataset retail prices? Wholesale prices? Farm-gate prices? • From whom are these prices collected? • For what volume are the prices collected? • For each commodity price that the CO will track: what are the commodity’s color, size, quality, and condition? • How frequently are these prices collected? • Are prices averages over time or across several traders?

  7. Obtaining secondary data • Find out how quickly secondary data will be available • Try to obtain data for the last 24 months, but ideally 60 months • Consider offering to make your data available to the secondary data provider • If your CO is heavily dependent on delayed secondary data, consider collecting some primary data for monitoring purposes

  8. During the interview: Map secondary price data collection processes by commodity
