Investment efficiency is a function of the risk, return and total cost of an investment management structure, subject to the fiduciary and other constraints within which investors must operate. Institutional investors implement their investment policies through investment management structures. In this paper the aim is to enhance the investment management structure by broadening the financial objectives, by recognising the effect of behavioural issues and by incorporating governance constraints. We therefore suggest that investment efficiency should be considered as a combination of financial efficiency and non-financial efficiency.

Modern portfolio theory had a revolutionary effect on portfolio construction. In the same way, we believe that investment management structures should be constructed in a more disciplined and quantitative manner. In this paper we outline the quantitative and qualitative methods by which these structures can be developed. The proposed new framework for designing investment management structures seeks to optimise net information ratios while simultaneously recognising the level of regret risk facing fiduciaries, minimising non-financially-productive behavioural biases and taking account of the resources available to the fiduciary to monitor these structures.

This Working Party has considered the pensions implications of a prolonged period of low inflation. Experience in the United States of America suggests weaker correlation between equity and bond returns and greater overall volatility of returns. Without a further significant increase in the valuation of equities relative to their underlying economic activity, the cost of pensions will rise, possibly as much as doubling within the next 15 years. It follows that for defined contribution schemes and personal pensions, current contribution levels are likely to produce disappointing and generally inadequate results. Similarly, the costs of defined benefit promises will increase. Future defined benefit provision is also vulnerable to the mismatch of mainly equity assets with mainly fixed liabilities and is therefore difficult to control. Many practical issues of scheme design still reflect past inflation and need to be addressed.

This paper describes how to calculate approximate prices of options if investment markets are being modelled according to the Wilkie investment model.
