Résumé en anglais

We define a repairable asset as an irreplaceable commodity whose quality is at risk, but can be partly restored at a cost. Examples are houses, automobiles and, especially, health, for which standard monetary approaches are oversimplified. To optimize the value of insurance, the insurer and the insured have to agree upon repair strategies (when to fix the asset and how much) and compensation rules (how much money to receive for other goods). We clarify the role of the consumer's preferences in the properties of the contract, and we highlight the relationship between repair strategies and the super- or submodular structure of the repair technology.
