Social security reform in Latin America: policy challenges.

Over the last decade Latin American countries have served as the world's laboratory for pension systems based on individual retirement savings accounts. Some countries have adopted defined-contribution individual accounts as a replacement for state-run pension systems; other countries have embraced mixed systems of have made individual accounts optional and supplementary. This article outlines some of the most significant elements of recent Latin American pension reforms and examines some of the most serious policy challenges faced by governments implementing the new systems of individual accounts, including the need to reduce administrative costs, limit evasion, incorporate new categories of workers into the system, and improve competition in the pension fund industry. The authors conclude that there is no single Latin America model, and that reform itself has been and will continue to be an incremental process.
