We develop a model of waiting lists for public hospitals when physicians deliver both private and public treatment. Public treatment is free but rationed, i.e., only cases meeting some medical criteria area admitted for treatment. Private treatment has no waiting time but entails payment of a fee.

This paper makes several contributions to the growing literature on the economics of religion. First, we explicitly introduce spatial-location models into the economics of religion.

The introduction of new (and expensive) pharmaceutical products is one of the major challenges for health systems. The search for new institutional arrangements is natural. The use of the so-called risk-sharing agreements is one example. Recent discussions have somewhat neglected the economic fundamentals underlying risk-sharing agreements. We argue here(More)
