Adverse Selection in the Irish Tontines of 1773, 1775, and 1777
Abstract
We construct and analyze a new data set on the mortality experience of the nomineesof the 1773, 1775, and 1777 Irish Tontines. The active participation of Genevan
speculators in these Irish Tontines has been well documented. We use our new data
to ascertain both the extent of their presence and the fact that the Genevan nominees
were indeed significantly longer-lived than non-Genevan nominees—particularly so
for the 50 nominees selected by a Genevan investment syndicate. We show that this
enhanced longevity had only trivial consequences for the Irish government issuer
but led to a investment return gap of approximately 7% between Genevan and non-
Genevan nominees in tontine issue which had the largest Genevan presence. These
findings have implications for recent proposals to introduce tontine-like features into
contemporary retirement plans.
