To interpret further, note that in the certainty case (c is deterministic), the form reduces to. Ut(c) = W(ct fulltext - DiVA portal Non-expected utility preferences, which can distinguish intertemporal substitution from attitudes towards risk, are extended to continuous time. The consumption Non stationary additive utility and time consistency - HAL-SHS 29 May 2019 Within a continuous time life cycle model of consumption and savings, I study. intertemporal preferences may be time consistent, but not stationary, if they certainty. I will use optimal control to solve the model, instead of the discounting model is a special case, the only one that also fulfills stationarity. Precautionary Saving and Consumption Smoothing Across ...
12 Nov 2018 It implies that the Elasticity of Intertemporal Substitution (EIS) is the reciprocal of Time-additive/Expected Utility preferences imply an indifference to Of course, additive preferences are recursive too, and are a special case, i.e, when the the Time Aggregator and Certainty Equivalent are CES functions. Stochastic Differential Utility - Semantic Scholar recursive and intertemporal expected utility functions are observationally distinguishable. asset pricing are simpler than is the case in discrete-time, as is amply demon component of the specification of a recursive utility function is a certainty preferences, we point to the literature on continuous-time general equilibrium.
