This paper aims to characterise a dynamic, incentive-compatible contract for the provision of health services, allowing for both moral hazard and adverse selection. Patients’ severity changes over time following a stochastic process and is private information of the provider. We characterise the optimal dynamic contract and show that it is made up of two components: a time-invariant payment, which depends on the structural characteristics of the provider, and a time-varying component, which is affected by both patient and hospital characteristics. To illustrate the characteristics of the dynamic contract and compare it with a more standard static contract, we provide a numerical exercise calibrated with data from hip replacement hospitalisations in Italy.
