Assessing the Feasibility of Micro-Data AccessOptions for SBS

Nadim Ahmad, Statistics Directorate, OECD

  • Increasing desire for micro-data access in analysis and policy formulation, accelerated by cheaper and faster computer power ......which in turn have increased capacity and potential for NSOs to provide access.
  • ‘Conservative’ rules relating to access however have led users to conduct own surveys = additional costs on users & respondents, and, so, the economy, which are often of lower quality than micro-data held by NSOs = risks of inappropriate policy measures & of NSOs being overtaken by events or marginalised.
the oecd s feasibility study options
The OECD’s Feasibility Study - Options
  • Overview
    • Snap shot indicators
    • Longitudinal indicators
    • Bilateral projects
    • Remote Access
    • Transmission of micro-data
    • Accessing private data sets
tentative conclusions
Tentative Conclusions
  • That the OECD should utilise networks to collect/construct indicators based on micro-data (Options I and II)
  • With a view to considering remote access solutions for the medium/longer term.
  • Creating a meta-data bank of micro-data, relating in the first instance to business statistics
implications for business statisticians
Implications for business statisticians
  • For the OECD to develop with NSOs/analysts a list of indicators that could be produced without compromising confidentiality.
  • E.g. for business statistics providing information relating to distributions, variances, standard deviations. Kurtosis, medians: broken down by size class, ISIC.
current indicators
Current Indicators
  • Turnover
  • Production at producers’ prices and/or factor costs
  • Value added at basic prices and/or factor costs
  • Gross operating surplus
  • Total purchases of goods and services
  • Change in stocks of goods and services
  • Purchases of energy products
  • Gross investment in tangible goods
  • Gross investment in land
  • Gross investment in existing buildings and structures
  • Gross investment in machinery and equipment
  • Sales of tangible investment goods
  • Employment, number of persons engaged and number of employees
  • Employment, number of females employees
  • Employment, number of employees in full time equivalent units
  • Hours worked by employees
  • Compensation of labour, all persons engaged and employees
  • Wages and salaries, all persons engaged and employees
  • Other employers’ social contributions, employees
  • Number of enterprises and/or establishments
composite indicators
Composite indicators
  • Extending the distribution statistics to composite indicators:
  • (Hirschman-Herfindhal) concentration indices;
  • Labour productivity, (arguably maximum and minimums too).
  • Labour/Capital ratios, (maximum and minimums);
  • Labour productivity growth;
  • Standard regression coefficients, for example linking output to labour and capital using KLEMS’ type production functions;
  • Operating surplus/employment ratios;
  • Turnover/Output ratios;
  • Social contributions % of total compensation;
  • New high-growth measures (session 2b); Growth more generally
  • Brainstorming (quartiles etc, higher ISIC aggregates, foreign ownership, exports, imports)
commercial sources proposal
Commercial Sources – Proposal
  • Investigation of Amadeus/Orbis
    • Tentative conclusions are that these are useful sources for micro-data analysis
    • But issues relate to representivity
    • Proposal is to benchmark (and gross-up) Amadeus data to SBS statistics on basis of size, ISIC, legal form and location – (views on feasibility, obstacles etc)
