In countries with large scale private and public funded pension arrangements, for example, the United States, Canada, Japan, the Netherlands, and the United Kingdom, one of the key decisions is how the contributions into the fund should be invested to best effect. The investment decision typically results in some form of risk sharing between members and sponsor in terms of (1) the level of contributions required to pay for all promised benefits, (2) the volatility of contributions required, and (3) the uncertainty of the level of benefits actually deliverable should the scheme be wound up or have to be wound up. Some of the risks associated with the pension benefits have a clear link with the economy and hence with other instruments traded in the financial markets. Others, such as demographic risks and the uncertainty as to how members or the sponsor will exercise their options, which are often far from being economically optimal, are less related to the assets held in the fund.
