Stochastic Differential Utility as the Continuous-Time Limit of Recursive Utility
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 Duffie and Epstein (1992), in the ...
