Summary of "An Assessment of Reform Options for the Public Service Pension Fund in Uganda"

Core Content

This paper evaluates the financial sustainability and reform options for the Ugandan Public Service Pension Fund (PSPF) under the provisions of CAP 286. It uses the World Bank Pension Reform Options Simulation Toolkit (PROST) to project future liabilities and analyze different reform pathways. The study concludes that a hybrid (two-pillar) reform—comprising a small defined benefit (DB) scheme and a larger defined contribution (DC) scheme—is preferable to a pure DC (monopillar) reform, despite the latter being more commonly discussed by policymakers.

The paper highlights the generosity of the current PSPF system, which includes early retirement at age 45, a short vesting period of 10 years, a high benefit accrual rate of 2.4% per year, and indexation of benefits to wages. These features, while beneficial in the short term, lead to increasing fiscal pressure due to demographic trends and the aging of the workforce.

Main Points

1. Current System Characteristics

• Non-contributory: The PSPF is funded by the government and not by employee or employer contributions.
• Coverage: Includes traditional civil servants, local authority civil servants, and primary and secondary school teachers.
• Benefits:
  • Old-age pensions (regular and commuted pension gratuity)
  • Survivor's pensions (equivalent to 100% of deceased public officers' pension entitlement)
  • Other gratuities (death, marriage, short service, etc.)
• Generosity:
  • High replacement rates (79.7% for civil servants, 83.4% for teachers)
  • Indexation of benefits to wages
  • High benefit accrual rate

2. Projected Financial Pressures

• System Dependency Ratios:
  • Civil servants: 23% to 35–40%
  • Teachers: 80% to 40–45%
• Pension Expenditure:
  • Civil servants: Expected to increase from 0.6% to 2.2% of GDP
  • Teachers: Expected to increase from 0.4% to 2.3% of GDP
• Required Contribution Rates:
  • Civil servants: Starts at 36%, rises to 40%
  • Teachers: Starts at 18%, rises to 45%
• Implicit Pension Debt (IPD):
  • Civil servants: 23% of GDP in the base year, expected to reach 100% by the end of the simulation
  • Teachers: 27% of GDP in the base year, expected to reach 110% by the end of the simulation
• Fiscal Impact:
  • The IPD indicates a significant subsidy from the general population to the covered population, reaching 50% of GDP in the base year and 100% by the end of the simulation.

3. Reform Options Analyzed

• Pure DC (Monopillar) Reform:
  • Makes the scheme fully contributory (15% contribution rate: 5% from employees, 10% from employers).
  • Leads to a significant reduction in government expenditure in the short term, but may result in lower replacement rates due to the lack of redistribution and pooling.
• Hybrid (Two-Pillar) Reform:
  • Combines a small DB scheme with a larger DC scheme.
  • Offers higher average replacement rates due to the DB component’s redistributive and pooling properties.
  • Has a similar impact on pension expenditure as the pure DC reform, assuming the same grandfathering rules and surplus in the first pillar.

4. Key Considerations in Reform Design

• Target Replacement Rates:
  • Should be around 40–50% for a typical worker to maintain subsistence levels.
  • Higher for lower-income workers, lower for higher-income workers.
• Scope of Reform:
  • Should include both new and existing employees to ensure long-term sustainability.
• Indexation:
  • Price indexation is more effective in reducing government expenditure than wage indexation.
• Asset Returns:
  • Higher returns on assets can improve replacement rates in DC components.
• Grandfathering Rules:
  • Affect the level of government expenditure and the design of the reform.

Key Findings

• The current PSPF system is generous, but this comes at a high fiscal cost.
• The system dependency ratio is expected to increase significantly over the next 70 years, worsening the financial sustainability of the scheme.
• Pure DC reform reduces government expenditure but may lead to lower replacement rates and higher fiscal burden in the long term.
• Hybrid reform is recommended as it maintains higher replacement rates and better redistribution while achieving similar fiscal benefits as pure DC reform.
• Implicit pension debt is a strong indicator of the fiscal burden and generosity of the system.
• Discount rate sensitivity is a critical factor in IPD calculations, with a 5% real discount rate used in this paper.

Policy Recommendations

• Implement a hybrid two-pillar pension system to balance fiscal sustainability with benefit adequacy.
• Include both new and current employees in the reform to ensure long-term viability.
• Use price indexation rather than wage indexation to reduce government expenditure.
• Consider realistic asset return assumptions to ensure that replacement rates remain adequate.
• Design grandfathering rules carefully to minimize the short-term fiscal impact.

Conclusion

The paper emphasizes the importance of reforming the PSPF to address the growing fiscal burden and ensure long-term sustainability. It advocates for a hybrid approach that preserves the redistributive and pooling features of the current system while introducing a contributory element to reduce reliance on general taxation. The recommended reform would allow for fiscal sustainability, adequate pension benefits, and greater equity in the pension system.
