WAGES, AGGREGATE SUPPLY DETERMINANT: One of several specific aggregate supply determinants assumed constant when the short-run aggregate supply curve is constructed, and that shifts the short-run aggregate supply curve when it changes. An increase in the wages causes a decrease (leftward shift) of the short-run aggregate supply curve. A decrease in the wages causes an increase (rightward shift) of the short-run aggregate supply curve. Other notable aggregate supply determinants include the technology, energy prices, and the capital stock. Wages are an example of a resource price aggregate supply determinant.

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.

FOUR-FIRM CONCENTRATION RATIO The proportion of total output in an industry produced by the four largest firms in an industry. This is one of two common concentration ratios. The other is the eight-firm concentration ratio. Another related measure is the Herfindahl index. The four-firm concentration ratio is commonly used to indicate the degree to which an industry is oligopolistic and the extent of market control held by the four largest firms in the industry.
