UK Budget Forecasters May Need Higher Productivity Outlook, Report Finds

Revised Productivity Measurements and Implications for UK Economic Policy

(Adds dropped word "to" in headline)

Sept 25 (Reuters) - Britain's budget forecasters may have to raise their downbeat view of productivity growth in the light of a new way of measuring it, but the revision is likely to be too late to help finance minister John Healey with his tax and spending plan announcement next month, a think tank said on Friday.

New Methodology for Measuring Productivity

Britain's official statistics office said last week that the pace of growth in output per hour in the country between 2007 and 2019 was almost twice as fast as previously thought, based on a new methodology using more reliable data.

Impact of Productivity Revisions

The Resolution Foundation said the change took the UK productivity growth rate from the Group of Seven's second worst to its second best, behind only the U.S. But Britain's level of productivity still lags well behind that of France and Germany.

Key Points from the Resolution Foundation's Release

  • Persistent Productivity Gap

    The persistent productivity gap between Britain and France and Germany even after the revision suggests its productivity problems are deep-rooted and may precede the global financial crisis, the think tank said

  • Government Response to Productivity Revisions

    the revisions suggested the government should do more to address a fall in hours worked - which was a key factor behind the higher productivity growth estimate - and to get more people into work, it said

  • Recent Improvements in Productivity Growth

    other assessments of recent data have shown an improvement in British productivity growth over the last couple of years that Healey has hailed as a sign of an economic turnaround

  • OBR's Outlook and Budget Implications

    "The OBR (Office for Budget Responsibility) may revisit its assumption in time, but sadly for the Chancellor this is unlikely to affect the forecast at this budget," said Simon Pittaway, principal economist at the Resolution Foundation

  • OBR's Previous Forecast Adjustments

    The OBR, whose forecasts underpin the budgets of British governments, last year lowered its view of future productivity growth.

Key Takeaways

  • New ONS methodology shows annual output‑per‑hour growth from 2009–19 is about 1.3%, almost double previous estimates, changing the UK's G7 ranking significantly (ons.gov.uk)
  • Despite revision, UK remains productivity‑lagging behind France and Germany, suggesting deep‑rooted structural issues (theweek.com)
  • Recent productivity growth measured by administrative data is stronger (~1.1% a year since Q3 2024), aligning with OBR’s revised medium‑term assumption—but too late to affect the upcoming Budget forecast (resolutionfoundation.org)
