  1. Non-market output: the view from national accounts David Caplan National Accounts Group, ONS

  2. Non market output • The challenge for national accountants • The UK experience • The issues arising • Concepts • Data • Relationships • Quality

  3. The challenge for national accountants • Seeking exhaustive coverage of the economy • Value output as equal to sum of inputs • Labour, depreciation and intermediate consumption • Traditionally deflate inputs to produce volume measure • But assumes no productivity change • Questionable assumption • SNA93 and ESA 95 proscribe direct measures of volume

  4. UK experience • Introduced some direct measures in 1998 • Health, education and social security administration • “first generation” measures • Noted at the time that developments would be needed • Not well handled by ONS • But measures of this nature can never be an all embracing summary of the output of a complex public service • National accounts statistics entered the Political domain • And then the Atkinson review

  5. Issues post Atkinson • Some things improved • Resources • Links with other government departments • Improved conceptual framework • Other things revealed on remain

  6. Concepts • What are we measuring • A particular problem for collective services • But may also be true for individual services where there is ambiguity about what is being produced

  7. Data • Partial coverage of category • Truncated time series • Poor timeliness • Lack of regular surveys • Limited geographical coverage • Future proof?

  8. Relationships • National accountants do not see the world in the same way as those in charge of delivery • Different concepts of output (education) • Different hurdles for data • Desire to show maximum value

  9. Measuring quality • the idea that quality improvements in the public services can be objectively measured and that such a fuzzy concept should be captured in the measurement of national output is absurd. • It's absurd that the current measure of productivity does not cover the range of massive improvements that are being seen across the NHS.

  10. Quality issues • Likely to be based on outcomes • Much more in this conference • Reliability (consistent over time and well measured) • Timeliness – may not be available quickly • UK education • Confounding with other factors • Comprehensiveness of measures • Quantifying the effects

  11. Conclusion • SNA said • There is no mystique about non-market health or education which makes changes in their volume more difficult to measure than volume changes for other types of output such as financial or business services. • But • No units or prices • Changing policies • Policy environment • Data difficulties • Maybe the authors of the SNA were over-optimistic.
