Safety of Low-Dose Quetiapine for Insomnia in Older Adults.

Background And Objective: Quetiapine is a Food and Drug Administration (FDA) approved second-generation antipsychotic. It is also commonly used at low dose for its sedative properties to treat insomnia in the older population. Quetiapine at standard doses has been associated with increased risk of cerebrovascular events, cognitive decline, and mortality in patients with dementia, especially within older adults.

Equilibrium Provider Networks: Bargaining and Exclusion in Health Care Markets.

We evaluate the consequences of narrow hospital networks in commercial health care markets. We develop a bargaining solution, "Nash- in-Nash with Threat of Replacement," that captures insurers' incentives to exclude, and combine it with California data and estimates from Ho and Lee (2017) to simulate equilibrium outcomes under social, consumer, and insurer- optimal networks. Private incentives to exclude generally exceed social incentives, as the insurer benefits from substantially lower negotiated hospital rates.
