Summary
- Policy advice and economic theory advocate for fiscal rules with a clear anchor that reflects fiscal risk and a robust correction mechanism that implements a more ambitious fiscal consolidation when fiscal risk is higher.
- Among more than 120 countries with fiscal rules, only six are identified as implementing such robust correction mechanisms: Armenia, Costa Rica, Cyprus, Czech Republic, Poland, and Slovakia.
- Using synthetic control methods and dynamic panel regressions, the paper finds that the introduction of fiscal rules with robust correction mechanisms has been particularly effective in these countries, triggering a persistent median spread reduction of about 25 percent, or 75 basis points, over one year.
Empirical methods and evidence
- Methods:
- Synthetic control methods.
- Dynamic panel regressions.
- Key empirical finding:
- Persistent median sovereign spread reduction of about 25 percent, or 75 basis points, over one year following the introduction of fiscal rules with robust correction mechanisms in the identified countries.
Policy implications and interpretation
- Fiscal rules that:
- Have a clear anchor reflecting fiscal risk, and
- Include robust correction mechanisms that mandate more ambitious consolidation when fiscal risk rises,
- Are associated with materially lower sovereign spreads in the sample of countries identified.
- The evidence supports the view that well-designed fiscal frameworks can reduce sovereign borrowing costs by signaling stronger fiscal credibility and responsiveness to fiscal risk.
