Boyd, J.,“Recursive Utility and the Ramsey Problem,” J. Econ. The – CrossRef Google ScholarCited by:   Second, additive utility is insensitive to uncertainty about the long-run fundamentals of the process—or parameter uncertainty, for short.

In the example above, the agent is indifferent between process P 1, where long-run average consumption is known with certainty, and P 2, Author: Nabil I. Al-Najjar, Eran Shmaya. () Expected Utility Maximization Problem Under State Constraints and Model Uncertainty.

Journal of Optimization Theory and Applications() Maximum Principles of Markov Regime-Switching Forward–Backward Stochastic Differential Cited by: This paper presents an axiomatic foundation for recursive utility that captures the role of the timing of resolution of uncertainty without relying on exogenously specified objective beliefs.

Two main representation results are proved. Under uncertainty, the recursive gain/loss asymmetric Recursive utility under uncertainty book satisfies the following stochastic recursive equation:(3)Ut({cτ}τ≥t)=Et[ϕ(essinfδ∈[δ̲t+1,δ¯t+1]{(1−δ)u(ct)+δϕ−1(Ut+1({cτ}τ≥t+1))})],where ϕis a continuous and strictly increasing function from Rto R,ϕ−1is the functional inverse of ϕ, and Etis a Author: Yuki Shigeta.

Downloadable (with restrictions). This paper axiomatizes a recursive utility model that captures both intertemporal utility smoothing defined across time and ambiguity aversion defined over states. The resulting representation adapts Wakai (Econometrica –, ) model of intertemporal utility smoothing as an aggregator function, where the utility of the certainty equivalent of.

The purpose of this book is to collect the fundamental results for decision making under uncertainty in one place, much as the book by Puterman [] on Markov decision processes did for Markov decision process theory.

In partic-ular, the aim is to give a uni ed account of algorithms and theory for sequential. With expected utility, you are indifferent between these lotteries, but with EZ lottery B is prefered iff >ˆ: In general, early resolution of uncertainty is preferred if and only if >ˆi.e. risk aversion > 1 IES:This is another way to motivate these preferences, since early resolution seems intuitively preferable.

We study a maximization problem from terminal wealth and consumption for a class of robust utility functions introduced in Bordigoni, Matoussi, and Schweizer [A stochastic control approach to a rob. The book goes on to treat equilibrium analysis, covering a variety of core macroeconomic models, and such additional topics as recursive utility (increasingly used in finance and macroeconomics), dynamic games, and recursive contracts.

) Conclusion (pg. This has spurred the development of new areas for research such as nonlinear dynamic expectation theory, e.g., g and G-expectation, and path-dependent partial differential equations, while also finding new applications for problems of ambiguity, uncertainty, quantitative risk, and recursive utility in finance and economics.

In a continuous-time setting with Brownian and Poissonian uncertainty, this paper formulates recursive utility under two smooth certainty equivalent (CE) types that have been proposed as. Downloadable. This paper axiomatizes an intertemporal version of multiple-ptiors utility.

A central axiom is dynamic consistency, which leads to a recursive structure for utility, to 'rectangular' sets of priors and to prior-by-prior Bayesian updating as the updating rule for such sets of priors. It is argued that dynamic consitency is intuitive in a wide range of situations and that the model.

bad uncertainty. Hence, both uncertainty risks contribute positively to risk premia, and help explain the cross-section of expected returns beyond cash flow risk.

other than expected utility. Under objective risk, neutrality toward timing (or preference for early resolution) cannot be combined with nonexpected util-ity preferences: any certainty equivalent other than E necessarily produces a nonuniform attitude to temporal resolution.

Overview of Results This paper studies choice under uncertainty. optimality and state pricing in constrained financial markets with recursive utility under continuous and discontinuous information Mathematical Finance, Vol. 18, No. 2 Foundations of Continuous-Time Recursive Utility: Differentiability and Normalization of Certainty Equivalents.

In economics, Epstein–Zin preferences refers to a specification of recursive utility. A recursive utility function can be constructed from two components: a time aggregator that characterizes preferences in the absence of uncertainty and a risk aggregator that defines the certainty equivalent function that characterizes preferences over static gambles and is used to aggregate the risk.

A principal feature of recursive utility, that distinguishes it from time-separable expected utility, is its dependence on the timing of resolution of uncertainty. Recursive Models of Dynamic Linear Economies Lars Hansen University of Chicago Utility of Income. Consumption Externalities.

This paper generalizes, in the setting of Brownian information, the Duffie–Epstein () stochastic differential formulation of intertemporal recursive utility (SDU).

We provide a utility functional of state-contingent consumption plans that exhibits a local dependency with respect to the utility intensity process (the integrand of the quadratic variation) and call it the generalized SDU. The new FIER algorithm under both interval probabilistic and fuzzy uncertainties Based on the fuzzy assessment set HF, a FIER (Fuzzy Interval grade ER) recursive algorithm is developed as follows using the similar technique used in Yang and Singh and Yang, et al (the detailed proof is shown in the Appendix).

13(4), p.Recursive utility functions are more general then the above parametrisation but this one is arguably the most common one. Agents are clearly risk-averse (dislike variation across different states) and clearly prefer an early resolution of uncertainty. The Technium Summary.

Under Poisson uncertainty, a smooth divergence CE can be approximated with an expected-utility CE if and only if it is of the entropic type. A nonentropic divergence CE results in a new class of continuous-time recursive utilities that price Brownian and Poissonian risks differently.

This chapter solves the optimal consumption and investment decisions of a rational individual in various settings. First, the simple one-period framework is considered, where straightforward utility-maximization under the appropriate budget constraint implies that the marginal rate of substitution of the individual - the ratio of marginal utility of future consumption to marginal utility of.

With more and more scholars studying, g-expectation has become a powerful tool for studying recursive utility theory and financial risk measurement [2] [3] [4].

The concept of g-expectation can be applied to handle a set of uncertain probabilities by reference probability P. Under what economists call a ‘time separable power utility’ specification of investor preferences commonly used in macroeconomics, a decision maker views the two lotteries as comparable.

In a more general ‘recursive utility’ specification, the intertemporal composition of risk can matter. Recursive Methods in Economic Dynamics [Nancy L. Stokey]. This rigorous but brilliantly lucid book presents a self-contained treatment of modern economic dynamics. Stokey, Lucas, and Prescott develop the basic methods of recursive analysis and illust.

For the most part, although not entirely, the first three chapters are a compression of Chapters 2 through 4 of my book Random Processes for Image and Signal Processing, aimed directly at providing a tight background for optimal signal processing under uncertainty, the goal being to make a one-semester course for Ph.D.
