In this paper, we study the theory of preference over unbounded random prospects using an axiomatic approach. We first show that Yaari's dual independence axiom can be decomposed into two axioms, the homogeneity axiom and the co-monotonic independence with respect to addition axiom, and we...

An expected utility based cost-benefit analysis is in general fragile to its distributional assumptions. We derive necessary and sufficient conditions on the utility function of the expected utility model to avoid this. The conditions ensure that expected (marginal) utility remains finite also...

In searching for the optimal preference-free solution for demand of risks, most existing models maximize risk-averse agents' expected utility with an implicit constant-solution assumption a priori. For these problems with unique solution, this extra assumption demands a restrictive distribution...

Expected utility functions are limited to second-order (conditional) risk aversion, while non-expected utility functions can exhibit either first-order or second-order (conditional) risk aversion. We extend the concept of orders of conditional risk aversion to orders of conditional dependent...

We introduce two subclasses of convex measures of risk, referred to as entropy coherent and entropy convex measures of risk. We prove that convex, entropy convex and entropy coherent measures of risk emerge as certainty equivalents under variational, homothetic and multiple priors preferences,...

This paper focuses on the attitude of non-professional investors towards financial losses and their decisions on wealth allocation, and how these change subject to behavioral factors. Our contribution concerns the integration of behavioral elements into the classic portfolio optimization....

An expected utility based cost-benefit analysis is in general fragile to its distributional assumptions. We derive necessary and sufficient conditions on the utility function of the expected utility model to avoid this. The conditions ensure that expected (marginal) utility remains finite also...

Necessarily, new technical change is facilitated by the development of new technical proficiencies. Whenever the claim to `new technical change' is robust, the accompanying `new technical proficiencies' facilitate an `outcome', in respect of which `old technical proficiencies' are intractable....

We consider an investor maximizing his expected utility from terminal wealth with portfolio decisions based on the available information flow. This investor faces the opportunity to acquire some additional initial information G.. The subjective fair value of this information for the investor is...

We consider a sovereign wealth fund that invests broadly in the international financial markets. The influx to the fund has stopped. We adopt the life cycle model and demonstrate that the optimal spending rate from the fund is significantly less than the fund's expected real rate of return. The...
