Résumé
The aim of this article is to propose a general analytical framework that can be transposed to different experiments and studies about individual preferences for connected objects (CO) at home. From revealed individual preferences for CO over time, as a substitute for non-connected time, we formalise a simple microeconomic optimisation model applied to two individuals assumed to share the same home. We show that individual preferences naturally seek a balance between time passed on CO, social link with the housemate and time devoted to other activities.
