The IMF has released a detailed study about the optimal design of fiscal policy to combat the crisis. A key feature of this report is that it accepts that the appropriate fiscal response varies across countries. In particular, this extract from an online interview with two of the report’s authors (Olivier Blanchard and Carlo Cottarelli) is relevant to the Irish situation:
Cottarelli: That said, it is critical that this fiscal stimulus isn’t seen by markets as undermining medium-term fiscal sustainability. That would be counterproductive, including in its effects on demand today. Indeed, we’ve said that not all countries can afford a fiscal expansion.
How the stimulus package is designed is also key: fiscal measures should be reversible, and governments may want to precommit to unwinding some of the policies. Also, any stimulus should be formulated within a robust medium-term fiscal framework, which could be made more credible by strengthening independent oversight of fiscal policy.
