Under risk, Arrow-Debreu equilibria can be implemented as Radner equilibria by continuous trading of few long …

Within the prospect theory the paper examines production and hedging decisions of a competitive firm under price … uncertainty. We consider the prospect theory for the firm's utility function in the two moment model known as (mu … theory, mean-variance model, price uncertainty …

We show that if an agent is uncertain about the precise form of his utility function, his actual relative risk aversion … may depend on wealth even if he knows his utility function lies in the class of constant relative risk aversion (CRRA … their risk aversion parameter invest less in risky assets than wealthy investors with identical risk aversion uncertainty. …

presented provides an ability to evaluate sustainable withdrawal rates and exposure to sequence risk together …

This paper extends decision making under risk and uncertainty to group theory via representations of invariant … behavioural space for prospect theory. First, we predict that canonical specifications for value functions, probability weighting … in decision theory. Moreover, representations include the special unitary group SU(2) and orthogonal group Θ …

We introduce three new families of reward-risk ratios, study their properties and compare them to existing examples … members only depend on the distribution of a return. In the second part of the paper we provide an overview of existing reward-risk …
