Investing Public Pensions in the Stock Market: Implications for Risk Sharing, Capital Formation and Public Policy in the Developed and Developing World

Concerns that existing public pension systems will be unable to pay benefits to a rapidly ageing population without sharp tax increases, and the prospect of higher average returns on stocks than on government securities, are drawing the attention of policy–makers worldwide to the option of investing public pension assets in stocks. Including stock market investments in public pension plans could improve risk sharing within and between generations, and could perhaps lead to faster market development in some countries. It could also result in excessive risk–taking, higher transactions costs and a false sense of increased financial security. This paper assesses these issues, with an emphasis on the considerations that are of special importance to developing markets. A contrast is drawn between the demographic outlook in East Asia and the major industrialized countries. Some lessons are drawn from the reform experience in Chile and elsewhere in Latin America.
