Chen, A., Haberman, S. ORCID: 0000-0003-2269-9759 & Thomas, S. ORCID: 0000-0001-5438-4263 (2019). The implication of the hyperbolic discount model for annuitisation decisions. Journal of Pension Economics and Finance, 19(3), pp. 372-391. doi: 10.1017/s1474747218000343


The low demand for immediate annuities at retirement has been a long-standing puzzle. We show that a hyperbolic discount model can explain this behaviour and results in the attractiveness of long-term deferred annuities. With a set of benchmark assumptions, we find that retirees would be willing to pay a much higher price than the actuarial fair price for annuities with longer deferred periods. Moreover, if governments were to introduce a pre-commitment device which requires pensioners to make annuitisation decisions around ten years before retirement, the take up rate of annuities could become higher.
