Separable choices
We introduce the novel setting of joint choices, in which options are vectors with components associated to different dimensions. In this framework, menus are multidimensional, being vectors whose components are one-dimensional menus, that is, nonempty subsets of elements associated to each dimension. We provide a natural notion of separability, requiring that selections from some dimensions are never affected by those performed on the remaining dimensions. Stability of separability across dimensions is throughly investigated. Moreover, we analyze rationalizable joint choices, which are those explained by the maximization of a revealed preference. The interplay between rationalizability e separability of joint choices allows to show that latter extends the classical definition of separability of discrete preference relations, and to assess the consistency of the former across dimensions.

Entangled vs. Separable Choice
We investigate joint probabilistic choice rules describing the behavior of two decision makers, each facing potentially distinct menus. These rules are separable when they can be decomposed into individual choices correl…
Decision MakingDid Harold Zuercher Have Time-Separable Preferences?
This paper proposes an empirical model of dynamic discrete choice to allow for non-separable time preferences, generalizing the well-known Rust (1987) model. Under weak conditions, we show the existence of value function…
Two-Step Estimation of a Strategic Network Formation Model with Clustering
This paper explores strategic network formation under incomplete information using data from a single large network. We allow the utility function to be nonseparable in an individual's link choices to capture the spillov…
ClusteringVocal Bursts Valence PredictionThe Implicit Bias of AdaGrad on Separable Data
We study the implicit bias of AdaGrad on separable linear classification problems. We show that AdaGrad converges to a direction that can be characterized as the solution of a quadratic optimization problem with the same…
General ClassificationParametric Graph-based Separable Transforms for Video Coding
In many video coding systems, separable transforms (such as two-dimensional DCT-2) have been used to code block residual signals obtained after prediction. This paper proposes a parametric approach to build graph-based s…
