Summary of Institutions, Performance, and the Financing of Infrastructure Services in the Caribbean

Core Content

This report, edited by Abhas Kumar Jha, explores the relationship between institutional frameworks, infrastructure performance, and financing in the Caribbean. It focuses on five key infrastructure sectors: telecommunications, electricity, water and sanitation, ports and maritime transport, and airports and air services. The study emphasizes how institutional quality and policy design significantly influence service delivery, investment needs, and financial sustainability in these sectors.

Main Sectors and Their Performance

1. Telecommunications

• Access and Usage: Some Caribbean countries, like Jamaica and Antigua and Barbuda, have higher access to telecom services than predicted by income levels.
• Technology and Market Liberalization: The adoption of mobile technology and market liberalization in the late 1990s transformed access. Jamaica and the Dominican Republic were early adopters of competitive mobile services.
• Tariff Trends: International calling rates were historically high, but reforms have brought them closer to competitive levels. However, some countries, like Haiti and the Dominican Republic, still struggle with excessively high international rates.
• Internet Costs: Internet services are more expensive in the Caribbean compared to similar income-level countries. For example, 20-hour dial-up in St. Lucia costs $22.22, while in Malaysia it is $8.42. High-speed internet can cost up to $400 per month in the Caribbean, compared to $40–50 in the U.S.
• Policy Recommendations: Countries that have not liberalized their markets should consider following successful models to improve access and affordability.

2. Electricity

• Access Rates: English-speaking Caribbean countries have electrification rates above 80%, while the Dominican Republic and Haiti lag behind at 70% and 40%, respectively.
• Cost Recovery: Most countries have tariffs that cover costs, but in the Dominican Republic and Haiti, tariffs are below cost, leading to financial strain.
• Fuel and Cost Drivers: The cost of electricity is influenced by fuel prices and generation efficiency. Countries like Trinidad benefit from low-cost indigenous gas, while others rely on more expensive imports.
• Regulatory Impact: Regulatory agencies in Barbados and Jamaica effectively incentivize efficiency and service quality. In contrast, weak regulatory frameworks in other countries have led to inefficiencies and "financial blackouts."
• Financial Blackouts in Dominican Republic: Due to frozen tariffs, lack of legal tools to enforce payments, and illegal grid connections, IPPs were forced to suspend production, leading to power cuts and public unrest.

3. Water and Sanitation

• Access Levels: Access to improved water sources is generally higher than access to electricity, with Haiti at less than 50% and the Dominican Republic and Suriname between 80% and 90%.
• Infrastructure Gaps: Despite access, many countries suffer from significant leakage, theft, and under-billing, leading to water rationing.
• Sanitation Challenges: Sewage networks are less developed than water supply systems, and wastewater is often inadequately treated, posing health and environmental risks.
• Tariff and Investment Needs: Water tariffs vary, and investment requirements are substantial. The report highlights the need for efficient management, investment in treatment and distribution, and institutional reforms to improve service quality and affordability.

4. Ports and Maritime Transport

• Economic Importance: Ports are vital for trade and economic growth. Intra-regional trade accounts for a significant portion of GDP.
• Port Efficiency: Countries like Jamaica and the Dominican Republic have relatively efficient ports, while others, especially smaller islands, face challenges due to limited economies of scale.
• Challenges: Issues such as high port charges, low throughput, and inadequate infrastructure hinder performance. Regional cooperation and modernization efforts are recommended.
• Case Studies: Examples include the Mauritius Port, Dubai Port, and Jawaharlal Nehru Port, which demonstrate the benefits of regulatory cooperation and investment in infrastructure.

5. Airports and Air Services

• Economic Role: Airports are critical for tourism and trade. Efficient airports contribute to economic growth and tourism development.
• Performance Metrics: Key indicators include runway length, passenger throughput, baggage handling, and airport charges.
• Challenges: Many Caribbean airports face inefficiencies, high charges, and limited connectivity. The Sangster International Airport in Jamaica and the Dominican Republic's airport sector are highlighted as case studies.
• Recommendations: Improving airport management, charging structures, and regulatory oversight is essential for enhancing performance and attracting investment.

Key Policy Findings and Recommendations

• Institutional Quality Matters: Strong, independent regulatory bodies and transparent governance are crucial for efficient infrastructure service delivery.
• Market Liberalization: Introducing competition in telecommunications and electricity has improved access and affordability.
• Tariff Reforms: Tariffs must reflect actual costs to ensure financial sustainability. Frozen tariffs and subsidies have led to financial blackouts and inefficiencies.
• Efficiency Gains: Reducing transmission and distribution losses, improving labor productivity, and adopting competitive procurement practices can lower costs.
• Regional Cooperation: Cross-border collaboration in regulation, infrastructure development, and financial market initiatives can enhance the performance of infrastructure sectors.
• Investment Needs: Substantial investment is required in all sectors to meet MDG targets and improve service quality. Public-private partnerships and output-based aid are suggested as viable financing models.

Conclusion

The report underscores that institutional reforms and policy changes are essential for improving the performance and sustainability of infrastructure services in the Caribbean. While technological and market developments have enhanced access, the quality of institutions remains a critical determinant of success. The findings suggest that a strategic approach to financing, regulatory modernization, and efficiency improvements can help Caribbean countries overcome structural disadvantages and provide more affordable, reliable infrastructure services.
