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…
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…
