n Studies in Economics and Econometrics - An evaluation of the BER's trade and building survey panels

Volume 26, Issue 1
  • ISSN : 0379-6205


During the late 1990s, researchers at the BER became concerned about the validity of its trade and building survey results. At that stage the panels of participants had last been updated in 1984. The response rate in some sectors was rather low and the sectoral weights probably no longer reflected the structural changes that occurred over the previous ten years or so. In accordance with international custom, deliberate sampling was used to re-design the BER?s trade and building panels. The BER?s trade and building panels are broadly fair reflections of the universe taking into account the response rate and the results of a comparison between the composition of the panels and censuses and other official data. The exception is sub-contractors. The building panel is representative of the formal sector, but not of the building sector as a whole, as it does not cover the informal sector.
