This paper analyses the formal retirement protection systems in five economically successful, rapidly industrializing, and globalized economies of Southeast Asia: Indonesia, Malaysia, the Philippines, Singapore, and Thailand. It finds that while there are major differences in the formal retirement protection systems of the five countries in terms of coverage; contribution rates; scope and nature of preretirement schemes; investment patterns, practices, and performance; replacement rates; administrative and compliance efficiency; and regulatory structures, the main common feature (with the exception of the Philippines) is aversion to social insurance and predominant reliance on individual provision through publicly mandated and managed provident funds. While these systems do minimize the fiscal burden on the State and thereby help maintain international competitiveness, they provide socially inadequate levels of retirement protection and are weak in ensuring efficiency of the saving-investment process. Moreover, several design and institutional features prevent full realization of many of the advantages of the provident funds found in these countries. They may, therefore, benefit by following the worldwide pension reform debate more closely, particularly concerning design and institutional and regulatory structures for mandatory defined-contribution schemes.
