Fiscal Consolidation: How much, how fast and by what means?


Fiscal Consolidation: How much, how fast and by what means? 

An Economic Outlook Report, OECD Economics Policy Paper No. 1, 12 April 2012

Key policy messages

  • Many countries face enormous fiscal consolidation challenges. Even if debt-to-GDP ratios stabilise over the medium term, they would remain at dangerous levels.
  • Countries should reduce debt levels to around 50% of GDP or lower to provide a safety margin against future adverse shocks.
  • Some countries – including Greece, Iceland, Ireland, Portugal and Spain – have started fiscal consolidations of between 5% and 12% of GDP, which are very large by historical comparison.
  • Other countries, notably, Japan, the United Kingdom and the United States require a fiscal tightening that would exceed 5% of GDP in order to bring their debt back to 50% of GDP by around mid-century.
  • Spending pressures, principally from health and long-term care will continue to mount, and could require an additional permanent fiscal tightening of several percentage points of GDP to help keep debt down in the future.
  • Due to the scale of consolidation needs, most countries will need a sustained period of fiscal tightening, acting on both the revenue and spending side.
  • The extent to which revenue or spending bears the brunt of consolidation will depend on whether spending is already high.
  • Given the current state of the economy and the already exhausted monetary stimulus, implementing a large degree of fiscal tightening could be particularly costly.
  • Using instruments with low multipliers initially may help minimise the trade-off with growth in the short run, but could involve other trade-offs, such as with credibility of the effort.
  • Given the scale of ageing and other spending pressures, reforms to entitlement programmes need to be an important part of any longer-term sustainability strategy.
  • Potential budgetary savings have been identified, which are either growth-friendly or have little adverse effect on economic activity. For most countries they amount to between 4% and 10% of GDP. More specifically:
    • Efficiency gains in public spending on health and education could yield savings of 0.5% to 4.5% of GDP in the longer term.
    • There is scope to broaden tax bases by eliminating tax expenditures (such as tax credits or deductions). These can be costly, with individual large items accounting for 1% of GDP or even more in many countries.
    • Environmental taxes, user fees for government services, taxes on immovable property and well designed financial sector levies could support fiscal consolidation while minimising welfare costs.
  • Fiscal institutions and fiscal rules may be helpful in buttressing credibility. In the longer run, better institutional frameworks can help ensure that fiscal policy stays on track.
