Stochastic differential utility as the continuous-time limit of recursive utility [PDF]

open access: yes, 2013
We establish a convergence theorem that shows that discrete-time recursive utility, as developed by Kreps and Porteus (1978), converges to stochastic differential utility, as introduced by Dufffie and Epstein (1992), in the continuous-time limit of ...
