PIGOUVIAN TAX: A tax on an external cost, such as pollution, designed to use market forces to achieve an efficient allocation of resources. A. C. Pigou, one of the first economists to study the market failure of externalities, is credited with developing this tax system for internalizing costs external to the market. An external cost caused by pollution, for example, can be internalized if polluters pay a tax equal to the value of the external cost.

OPEN ECONOMY

An economy that engages in international trade, especially one that exports goods and services to, and imports goods and services from, other economies that make up its foreign sector. It is "open" in the sense that goods and services flow into and out of the country. The alternative to an open economy is a closed economy, one that does not engage in international trade.
