Strategies for Fiscal Consolidation in Japan

IMF Working Papers, February 1, 2007

Investigates the macroeconomic implications of alternative fiscal strategies for Japan using the IMF's Global Fiscal Model.
Primary policy question: how to put public finances on a more sustainable footing given aging-related fiscal pressures.

An adjustment package that achieves primary balance through lower social transfers and government spending and a higher VAT is the most viable option and has a smaller negative impact on growth than other fiscal measures.
Achieving primary balance is not sufficient to stabilize the net debt ratio.
Prefunding future aging costs provides greater long-term benefits compared with less front-loaded strategies.
Tax reform involving shifting from corporate taxation to consumption taxation could mitigate the short-term output losses associated with fiscal consolidation.
The spillovers to the rest of the world from consolidation in Japan are positive in the medium term, but modest.

Prioritize an adjustment mix emphasizing:
- Reductions in social transfers and government spending, combined with
- A higher value-added tax (VAT).
Recognize that reaching primary balance alone does not stabilize net debt—further measures or prefunding are required.
Consider front-loaded prefunding of aging-related costs to secure greater long-term benefits.
Implement tax reform that shifts the burden from corporate taxation toward consumption taxation to lessen short-term output losses during consolidation.
