PHYSICAL WEALTH, AGGREGATE EXPENDITURES DETERMINANT: One of several specific aggregate expenditures determinants assumed constant when the aggregate expenditures line is constructed, and that shifts the aggregate expenditures line when it changes. A decrease in physical wealth causes an increase (upward shift) of the aggregate expenditures line. An increase in physical wealth causes a decrease (downward shift) of the aggregate expenditures line. Other notable aggregate expenditures determinants include consumer confidence, federal deficit, inflationary expectations, and exchange rates.

  • For small changes in production, up or down, the oligopolistic firm maintains existing production and price.

  • This is the source of price rigidity for oligopoly.

AVERAGE PRODUCT CURVE

A curve that graphically illustrates the relation between average product and the quantity of the variable input, holding all other inputs fixed. This curve indicates the per unit output at each level of the variable input. The average product curve is one of three related curves used in the analysis of the short-run production of a firm. The other two are total product curve and marginal product curve.
