Advancing annuity demand theory, we present sufficient conditions for the optimality of full annuitization under market completeness that are substantially less restrictive than those used by Yaari (1965). We examine demand with market incompleteness, finding that positive annuitization remains...

This paper advances the theory of annuity demand. First, we derive sufficient conditions under which complete annuitization is optimal, showing that this well-known result holds true in a more general setting than in Yaari (1965). Specifically, when markets are complete, sufficient conditions...

Advancing annuity demand theory, we present sufficient conditions for the optimality of full annuitization under market completeness which are substantially less restrictive than those used by Menahem E. Yaari (1965). We examine demand with market incompleteness, finding that positive...
