RT Journal Article SR Electronic T1 The Effects of Spending Rules and Asset Allocation on Nonprofit Endowments JF The Journal of Portfolio Management FD Institutional Investor Journals SP 81 OP 106 DO 10.3905/jpm.2022.1.431 VO 49 IS 1 A1 Zachery Halem A1 Andrew W.

Using a dynamic model, the authors explore how different endowment spending rules (SRs) influence the dynamics of an endowment’s size and future spending. They find that different parameters within each SR have significant long-term impact on wealth accumulation and spending capacity. Using Merton’s (1993) endowment model and compiled asset-allocation data, they estimate the intertemporal preferences and risk aversion of several major endowments and find significant variation across endowments in their propensity to increase portfolio risk in response to increased spending needs.
