A distance-based theory of lottery complexity
Giulio Principi
We propose a measure of lottery complexity that combines probabilistic dispersion with dissimilarity between outcomes. Taking degenerate lotteries, which yield a single outcome wit…
Absolute and Relative Ambiguity Attitudes
Francesco Fabbri, Giulio Principi, Lorenzo Stanca
We represent preferences that exhibit absolute or relative attitudes towards ambiguity without assuming convexity of preferences. Our analysis is motivated by the recent experiment…
Allocation Mechanisms in Decentralized Exchange Markets with Frictions
Mario Ghossoub, Giulio Principi, Ruodu Wang
The classical theory of efficient allocations of an aggregate endowment in a pure-exchange economy has hitherto primarily focused on the Pareto-efficiency of allocations, under the…
On the Weighted Top-Difference Distance: Axioms, Aggregation, and Approximation
Andrea Aveni, Ludovico Crippa, Giulio Principi
We study a family of distance functions on rankings that allow for asymmetric treatments of alternatives and consider the distinct relevance of the top and bottom positions for ord…
Anticomonotonicity for Preference Axioms: The Natural Counterpart to Comonotonicity
Giulio Principi, Peter P. Wakker, Ruodu Wang
Comonotonicity (``same variation'') of random variables minimizes hedging possibilities and has been widely used, e.g., in Gilboa and Schmeidler's ambiguity models. This paper inve…
A Nonlinear Sandwich Theorem
Mario Ghossoub, Giulio Principi, Lorenzo Stanca
We provide a Sandwich Theorem (König (1972)) for positively homogeneous functionals that satisfy additivity only on a restricted domain. Our relaxation of additivity is based on a…
Recursive Preferences and Ambiguity Attitudes
Massimo Marinacci, Giulio Principi, Lorenzo Stanca
Monotonicity and recursivity are central assumptions in intertemporal consumption problems under ambiguity. We show that monotone recursive preferences admit both a recursive and a…
Conditional divergence risk measures
Giulio Principi, Fabio Maccheroni
Our paper contributes to the theory of conditional risk measures and conditional certainty equivalents. We adopt a random modular approach which proved to be effective in the study…
Representations of cones and applications to decision theory
Paolo Leonetti, Giulio Principi
Let be a cone in a locally convex Hausdorff topological vector space containing . We show that there exists a (essentially unique) nonempty family of nonem…
