Dummy Variable

An alternative name for a binary variable, which takes the value 1 or 0. Dumping

A refusal by a health care provider to treat patients whose costs are expected to exceed the compensation payable to the provider. It arises particularly in systems that are dependent on private health insurance arrangements. In the USA, federal patient-dumping law entitles people in emergency situations to be screened, receive emergency care and to be appropriately transferred to another provider. A hospital must provide 'stabilizing care' for a patient with an emergency medical condition. The hospital must screen for the emergency and provide the care without inquiring about ability to pay. Although emergency cover is thus assured (in the USA), there is less assurance about non-emergency care for people who lose their jobs or change jobs (and who lose cover that was previously provided through a workplace arrangement).

106 Duopoly

Note that this is quite different from the usual notion of 'dumping' in international trade: selling goods abroad below their normal market value or below the price charged for them in the domestic market of the exporting country. This form of dumping can be a predatory trade practice whereby the international market, or a certain national market, is flooded with dumped goods in order to force competitors out of the market and establish a monopoly position.
