The assumed benefits of diversification – reducing the reliance of individuals on one form of
retirement insurance – currently inform policy advice on pension reforms. The diversification
argument also often justifies reforms of old age pensions, including their privatization.
However, the merits of diversification, particularly if pursued through privatization, are
questionable. First, actual gains from diversification are limited. Private pension systems
are not immune to regulatory risks, as often assumed. Moreover, diversification cannot
protect against the macroeconomic shocks that represent the main challenges for pension
systems. Secondly, the macroeconomic gains from private pillars are often overestimated
in the policy debate. Finally, the costs of diversification through privatization are very high,
despite the popular myth about reducing the implicit debt. In reality, retaining debt in its
implicit form is the preferable option for public finances.
