Summary of "Investing in Public Investment: An Index of Public Investment Efficiency"

Core Content

This working paper introduces the Public Investment Management Index (PIMI), a new composite index designed to measure the efficiency of public investment management across four key stages: strategic guidance and project appraisal, project selection, project implementation, and project evaluation and audit. The index is constructed for 71 countries, including 40 low-income countries, and aims to provide a benchmarking tool for policy analysis and reform prioritization.

The PIMI is distinct from traditional physical infrastructure indicators, as it focuses on the institutional and procedural efficiency of the public investment process. This is crucial because inefficient public investment can lead to poor returns, reduced growth, and fiscal unsustainability, especially in low-income countries where infrastructure deficits are significant.

Main Viewpoints

• Public investment is essential for growth in low-income countries, particularly in infrastructure.
• Institutional quality in the investment process significantly affects the productivity and effectiveness of public investment.
• Weaknesses in project appraisal, selection, implementation, and evaluation are common in low-income countries, leading to poor outcomes and wasteful spending.
• PIMI addresses these issues by capturing the quality and efficiency of public investment management across different stages.
• Data availability and interpretation pose challenges in constructing the index, and some aspects of public investment management are difficult to quantify due to limited data or system-specific contexts.

Key Information

Components of the PIMI Index

The index is composed of 17 indicators grouped into four stages:

1. Strategic Guidance and Project Appraisal

   • Availability of strategic guidance and sector strategies
   • Transparency of appraisal standards
   • Independent review of appraisals

2. Project Selection and Budgeting

   • Existence of medium-term planning frameworks
   • Integration of investment and recurrent expenditures in the budget
   • Public access to fiscal information
   • Inclusion of donor-funded projects in the budget

3. Project Implementation

   • Degree of open competition in contract awarding
   • Existence and operation of procurement complaints mechanisms
   • Funding flows during budget execution
   • Internal controls and audit effectiveness

4. Project Evaluation and Audit

   • Conduct of ex-post evaluations
   • External audits and their scrutiny by the legislature
   • Maintenance of asset registers and their subject to external audit

Index Construction

• The index is qualitative, with scores ranging from 0 to 4 for each indicator.
• Coding rules were applied to minimize subjectivity and ensure consistency.
• Data sources include:
  • World Bank Public Investment Management (PIM) case studies
  • PEFA (Public Expenditure and Financial Accountability) assessments
  • Budget Institutions database
  • World Bank Public Expenditure Reviews (PERs)
  • Country websites

Country Scores and Comparisons

• The PIMI provides country scores that allow for benchmarking across regions and income groups.
• It has been compared with existing institutional indices, highlighting its unique focus on the investment process.
• The robustness of the index has been tested, showing that it is sensitive to different weighting schemes and data sources.

Applications

• The PIMI can be used for cross-country analysis, policy evaluation, and reform prioritization.
• It offers a new dataset that can be used to assess the institutional environment for public investment and guide fiscal and technical reforms.
• The index is particularly useful in identifying weaknesses in the investment process that may hinder growth and fiscal sustainability.

Limitations and Caveats

• The index is not exhaustive, as it is constrained by data availability.
• Asset maintenance and project monitoring are difficult to quantify, limiting the index’s scope.
• System-specific interpretations of data can affect the accuracy of the index.
• The focus is on central government investment processes, with sub-national and PPP aspects not directly included due to data limitations.

Conclusion

The PIMI is a pioneering tool for assessing the efficiency and quality of public investment management in low and middle-income countries. It highlights the importance of institutional reforms and technical improvements in the investment process to enhance growth and fiscal sustainability. The paper calls for further research to refine the index and improve data collection in key areas such as asset management and project monitoring.
