Policy Space Index Summary

The paper introduces a new Policy Space Index to quantify a country's ability to respond to catastrophic events in the short term. It combines fiscal, monetary, and reserve space components with adjustments for institutional features such as currency status, income group, access to capital markets, debt distress risk, and exchange rate regime.

Key Components

• Fiscal Space: Includes borrowing space (debt sustainability) and financing space (gross financing needs threshold).
• Monetary Space: Measures central banks' capacity to lower policy rates or use unconventional tools, considering inflation targets and exchange rate regimes.
• Reserve Space: Based on reserve adequacy thresholds (e.g., months of imports or short-term debt coverage).

Institutional Adjustments

• Reserve Currency Countries (RCCs): Benefit from amplified policy space due to the ability to create money without limits.
• Income Group: Advanced economies (AE) have higher sustainability thresholds and negative rate capacity, while low-income countries (LICs) face stricter constraints.
• Access to Capital Markets: Full access increases policy space; limited or no access reduces it.
• Debt Distress Risk: High risk severely restricts fiscal space for LICs.
• Exchange Rate Regime: Flexible regimes allow fuller use of monetary space; fixed regimes restrict it.

Calculation Method

The index uses a probabilistic approach to define nominal policy space based on thresholds and normal distributions, then adjusts for institutional factors. Effective policy space is the sum of three components, bounded by zero, and calculated for country groups to ensure comparability.

Application to Covid-19 Crisis

• Approximately 8% of global GDP comes from countries with no or very limited policy space, requiring emergency assistance.
• Countries were classified into five groups based on available policy space:
  • RCCs with unrestricted space.
  • RCCs with restricted space.
  • Non-RCCs with substantial space.
  • Non-RCCs with limited or conditional space.
  • Non-RCCs with no policy space.
• Findings highlight that fiscal policy was the primary response, with LICs having the least capacity.

Limitations and Conclusions

• The index is static and may miss dynamic interactions between components.
• It is less robust for LICs due to data limitations and country-specific factors.
• The index is useful for short-term crisis response assessment and can guide policymakers to strengthen resilience.

This index provides a comprehensive framework for evaluating policy space but requires further refinement for operational use.
