Nontrivial decision problems typically involve a trade-off among multiple attributes of choice options. One simple way of resolving such trade-offs is to aggregate multiple attributes into one real-valued index, known as weighted or separable utility. Applications of weighted utility can be...

Geometric utility theory is proposed for modeling decision making under risk and uncertainty. If a decision maker's preferences satisfy four standard behavioral assumptions (completeness, transitivity, continuity and the independence axiom) then they admit a geometric utility representation....

This paper proposes a new axiomatic model of intertemporal choice that allows for dynamic inconsistency. We weaken the classical assumption of stationarity into two related axioms: stationarity in the short-term and stationarity in the long-term. We obtain a model with two independent discount...

This paper presents an overlapping generations household model with positive assortative matching (richer individuals marry richer partners), incomplete information about partner's type (it takes time to reveal income-earning capabilities of individuals) and a gender wage gap on the labor market...
