The Effects of Social Pressure on Fundamental Choices: Indecisiveness and Deferral
Alfio Giarlotta, M. Ali Khan, Angelo Enrico Petralia +1
In mainstream neoclassical economics, utility maximization is the only engine of individual action, and the other or the social, if it is modeled for decisions deemed fundamental,…
Separable joint choices
Davide Carpentiere, Alfio Giarlotta, Angelo Petralia +1
We introduce a novel choice dataset, called joint choice, in which options and menus are multidimensional. In this general setting, we define a notion of choice separability, which…
A rational measure of irrationality
Davide Carpentiere, Alfio Giarlotta, Stephen Watson
All possible types of deterministic choice behavior are classified by their degree of irrationality. This classification is performed in three steps: (1) select a benchmark of rati…
Rationalization of indecisive choice behavior by majoritarian ballots
José Carlos R. Alcantud, Domenico Cantone, Alfio Giarlotta +1
We describe a model that explains possibly indecisive choice behavior, that is, quasi-choices (choice correspondences that may be empty on some menus). The justification is here pr…
On the number of non-isomorphic choices on four elements
Alfio Giarlotta, Angelo Petralia, Stephen Watson
We use a combinatorial approach to compute the number of non-isomorphic choices on four elements that can be explained by models of bounded rationality.
Semantics meets attractiveness: Choice by salience
Alfio Giarlotta, Angelo Petralia, Stephen Watson
We describe a context-sensitive model of choice, in which the selection process is shaped not only by the attractiveness of items but also by their semantics ('salience'). All item…
Resolutions of Convex Geometries
Domenico Cantone, Jean-Paul Doignon, Alfio Giarlotta +1
Convex geometries (Edelman and Jamison, 1985) are finite combinatorial structures dual to union-closed antimatroids or learning spaces. We define an operation of resolution for con…
Robust sustainable development assessment with composite indices aggregating interacting dimensions: the hierarchical-SMAA-Choquet integral approach
Silvia Angilella, Pierluigi Catalfo, Salvatore Corrente +3
The evaluation of sustainable development - and, in particular, rural development - through composite indices requires taking into account a plurality of indicators, which are rela…
The Satisfiability Problem for Boolean Set Theory with a Choice Correspondence
Domenico Cantone, Alfio Giarlotta, Stephen Watson
Given a set U of alternatives, a choice (correspondence) on U is a contractive map c defined on a family Omega of nonempty subsets of U. Semantically, a choice c associates to each…
Extending rational choice behavior: The decision problem for Boolean set theory with a choice correspondence
Domenico Cantone, Alfio Giarlotta, Pietro Maugeri +1
Given the family of all nonempty subsets of a set of alternatives, a choice over is a function such that and for all…
Perfect Information vs Random Investigation: Safety Guidelines for a Consumer in the Jungle of Product Differentiation
A. E. Biondo, A. Giarlotta, A. Pluchino +1
We present a graph-theoretic model of consumer choice, where final decisions are shown to be influenced by information and knowledge, in the form of individual awareness, discrimin…
