The paper reviews models of the physician-patient relationship to derive testable hypotheses about the relation between health, demand for medical services and patient's compliance. The models imply that in addition to existing information asymmetries the actions that physician and patient...

We analyze a rating agency's incentives to distort ratings in a model with a monopolistic profit maximizing rating agency, a continuum of heterogeneous firms, and a competitive market of risk-neutral investors. Firms sell bonds, the value of a firm's bond is known to the firm and observable by...
