Readers Question. Can you explain why the Government and Economic Commentators are talking about a multiplier (in relation to budget cuts) of between 0.5 and 1, whereas I always thought that the GDP multiplier was bigger than this.
Just to summarise a multiplier of 0.5 would mean fiscal consolidation (spending cuts) of £1bn, would lead to a drop in GDP of only £0.5bn. In other words, they hoped fiscal consolidation would be successful and only have a limited impact on reducing economic growth rates.
However, evidence from the IMF and other studies have shown the fiscal multiplier has proved much higher. In fact a multiplier of up to 2. (for every spending cut of £1bn, we have seen GDP fall £2bn. See: Fiscal multiplier and European austerity).
Essentially, this shows the limitations of using economic models which are applied during very different economic circumstances. If you look at previous attempts at fiscal consolidation undertaken during strong economic growth (e.g. Canada in 1990s), a multiplier of 0.5 would be quite reasonable.
However, there was an unwillingness to admit that the economic situation in the aftermath of a financial crisis and liquidity trap was very different.
Why might the Government and European Commentators expect a multiplier of 0.5?
To some extent, I answered this yesterday on the post – why austerity will increase the budget deficit. But, just to recap, the may have hoped for a multiplier of 0.5 because:
1. Expansionary monetary policy. With spending cuts, usually a Central Bank can cut interest rates and loosen monetary policy so that there is a boost to demand to offset the impact of tax increases and spending cuts.
- But, the EU and UK government should have realised that interest rates were already at record lows in 2010. Quantitative easing has done little to boost spending in the UK. In Europe, the ECB has never showed any real sign of loosening monetary policy in response to fiscal consolidation. In fact in 2011, the ECB increased interest rates over misplaced fears on inflation.
