Here are 3 key enhancements proposed to further develop the Expected Return methodology:
1. Modeling interdependencies between investments to more accurately assess tradeoffs
2. Optimizing investment portfolios based on foundations' funding and staffing constraints
3. Discounting future benefits using an appropriate social discount rate, since benefits received in the future are less valuable than those today.
These enhancements aim to make the Expected Return framework more robust and useful for complex philanthropic decision making.
