Efficient intertemporal allocations with recursive utility

In this article, our objective is to determine efficient allocations in eco nomies with multiple agents having recursive, non-time-additive utility fun ctions. Our main result is to show that in a multi-agent economy, the probl em of determining efficient allocations can be characterized in terms of a single value function (that of a social planner), rather than multiple func tions (one for each investor), as has been proposed thus far (D. Duffie et al., 1994, J. Math. Econ. 23, 133-146). We then show how the single value f unction can be identified using the familiar technique of stochastic dynami c programming.
